Choosing a Gearbox Drive and Electric Motor Supplier

When choosing manufacturing partners during a machine build, remember that there are two methods for choosing a gearbox and electric motor supplier. One is selecting a pre-engineered unit and the other is choosing a gearbox-motor combination and integrating them into the equipment.

Pre-engineered gearmotor solutions are suitable if a design engineer doesn’t have the time or engineering resources to build a gearmotor in-house — or if the design needs a quick setup. New modular approaches to support OEMs (and enable new machine tools, automation, and design software) now let engineers get reasonably priced gearmotors even in modest volumes.

It’s true that one benefit to selecting a separate motor and gearbox and then combining them can less expensive than choosing a pre-engineered gearmotor. Another benefit to this approach is that one may be able to design the most optimized gearmotor for the application at hand … because this approach also gives the design engineer the most control over the final configuration and cost.

No matter the approach to gearmotor selection, be sure to continually improve the design by comparing predictions of performance with measurements. Then use the result of the analysis to improve next gearmotor iteration.

Strategies for Assessing and Optimizing Bearing Running Noise

How does the gearbox housing amplify noise?

Whitepaper written for Power Transmission Engineering by Dr. Hannes Grillenberger and published with permission from the Schaeffler Group USA

An important quality feature requires an effective assessment strategy

The noise behavior of rolling-element bearings is an important indicator of quality. Accordingly, it is a high-priority feature for customers. With the proliferation of electric motors in applications such as electric vehicles and household appliances, customers are also becoming more sensitive to bearing-induced vibrations. To effectively address these concerns, it is important to optimize bearings not only by testing but also by means of validated simulation methods. But while simulations provide useful information, they can be complicated to use. This creates a need for easy-to-use rating and limiting values that can facilitate proper bearing assessment and selection for each particular application.

The article will both provide an overview of the complex simulations applied to certain aspects of rolling-element bearing noise as well as introduce a catalog-based rating index known as the “Schaeffler Noise Index” (SGI).

Simulation methods for investigating bearing running noise

CABA3D simulation tool

Simulations of bearing noise may be done with Multi-Body-Simulation (MBS), a physics-based simulation tool that uses the power of a computer to design, evaluate and refine complex systems using sophisticated mathematical modeling and solution tools. To that end, Schaeffler has developed the CABA3D MBS tool [1, 2]. When using MBS, an accurate contact model is essential to accurately model the mechanical response of the bearing. In addition to the contact model, the inner bearing geometry significantly impacts the bearing’s stiffness and the degree of its variation. This can be an issue if the simulation is performed using commercial software, as these internal parameters may not be made available by the bearing manufacturer.

Of course, MBS is not the only method for analyzing bearing dynamics and vibration. Finite Element Analysis (FEA) is another popular simulation tool, but it requires long simulation times as transient calculations need to be performed – a significant drawback.

The following paragraphs provide a brief insight into some validation techniques as well as the possibilities of running noise simulation.

Schaeffler Noise Index - SGI
Fig. 1 FEA and BMS calculations on the displacement of an NU-type bearing caused by waves on the rings.

How waves on bearing rings affect noise

This effect is investigated using both the CABA3D MBS tool and FEA on an NU-type cylindrical roller bearing radially loaded with 37.7% of the static load rating C0. The waves are applied on the rotating inner ring with an amplitude of 9.7*10e-3% of the inner race diameter and wave numbers of 2 and 7 as well as both waves combined in phase. The inner ring is rotating at 9.3% of the bearing’s limiting speed. In these simulations, the outer ring is locked in all degrees of freedom, and the inner ring is completely free except for the constant rotation. The assessed dimension is the displacement speed of the inner ring in the radial direction perpendicular to the load direction. The graphs show the duration of the simulations for the three configurations. The strong correlation between the amplitudes and frequencies of the MBS results and the FEA results can be seen as positive.

Grinding marks on rollers

Grinding marks on rollers are typically the result of a manufacturing defect. Although such defective rollers would not be used in a bearing intended for sale, they serve as a good validation example for the simulation. The impact of the grinding marks usually masks all other effects of further tolerances and allows a comparison of testing results and the idealized simulation.

The graph in Fig. 2 shows the envelope spectrum of testing and simulation data from the radial vibration acceleration on the outer diameter of a cylindrical roller bearing with a grinding mark on one roller. The grinding mark has a depth of 0.25% of the roller diameter. The load on the bearing is 2% of C0, and the rotational speed is 7.8% of the limiting speed of the bearing. Due to the very good agreement of the spectra, the simulation can be interpreted as having been validated.

Fig. 2 Envelope spectra of an NJ-type bearing with grinding marks on rollers.

As with any comparison of data, employing the correct set of boundary conditions can be crucial because they influence the resonance of the system being analyzed. Especially when regarding absolute amplitudes, the boundary conditions must be as similar as possible. For comparisons that are made using test data, the simulation also must take into account the salient features of the test rig that was used. These “salient features” must be identified since each application is different. However, if an “A to B” comparison is being made, then the boundary conditions may also be disregarded in favor of the lower modeling effort and shorter calculation times.

Radius sorting of tapered rollers

During production, the diameter of tapered rollers can vary within a certain tolerance range, which may lead to noise. For our investigation, the radius sorting takes into account sorting spread and relative sorting. For the spread definition, an initial spread of x in the low micron range is assumed and scaled by 0, 1, 2, 4 and 8. Three different statistical sequences are generated as sort sequences, along with a scenario where all rollers (except for a larger one) have the same diameter. The sequences are scaled by the spread of the simulation.

The diameter spread effects the noise of the bearing in three different mechanisms:

1. Ring position due to roller diameters:

Due to the different roller diameters, the rings are not ideally aligned. Instead, they are tilted and shifted toward each other, which causes vibrations as the bearing is rotating. The degree of tilting and shifting is primarily dependent on the sorting spread.

2. Additional tilting of the ring:

If the relative sorting causes the support of the rings to become unstable, they may additionally tilt and, consequently, vibrate even more. This effect depends on the sorting sequence and is augmented by high diameter spreads as an unstable position becomes more likely.

3. Cage dynamics:

These simulations are done for a roller-guided cage. For a horizontal bearing axis, the cage center of mass (CoM) is shifted downward due to the effects of gravity on an ideal bearing. Depending on the roller diameters, different types of dynamics can be seen. In the red sorting simulation shown in Fig. 3, the cage guidance is passed from roller to roller. This results in a vibration of the bearing ring with the ball-passing frequency of the outer ring (BPFO) and its multiples. This can also be seen in the vibration spectrum of the ring as the guidance force is transmitted to the rings with that frequency (Fig. 4).

Fig. 3 Cage center of mass trajectories for two different rolling element sorting simulations.
Vibration spectrum of the bearing due to different cage dynamics excited by roller sorting.
Fig. 4 Vibration spectrum of the bearing due to different cage dynamics excited by roller sorting.

For the green roller sorting simulation shown in Fig. 3, the cage CoM orbits with the roller set frequency, and it is being guided by only some of the rollers. This results in vibration with the roller set frequency (fundamental train frequency/FTF) and its multiples. This can be seen for another sorting simulation, which is shown in blue in Fig. 4. Because centrifugal force has a significant impact on orbiting cages, this effect is both sorting- and speed-dependent.

Schaeffler Noise Index (SGI)

The above-mentioned possibilities regarding simulation of individual bearing noise behavior caused by typically unwanted effects are an important step toward establishing the overall noise-level calculation. Based on highly sophisticated tools, the Schaeffler Noise Index (SGI) was developed to provide a catalog-level rating tool that can quickly rate and compare bearing noise. The SGI’s development was motivated by a desire to understand which bearing emits the minimum noise for a given static load rating – a question that, until now, could only be answered through experience or measurement. With regard to experience, each case may be individually different and will usually give qualitative results. Measurement, on the other hand, is complicated and time-consuming. In contrast, the Schaeffler Noise Index is a quantitative measure that quickly provides results and offers users the opportunity to make comparisons between bearing types.

Because the SGI is derived from and certified by Schaeffler’s internal standards, it is currently only available for Schaeffler bearings. It displays the maximum permissible vibration level for reference conditions described in ISO 15242.

This definition leads to two main characteristics: Because the SGI is derived from certain basic requirements, an individual bearing usually has lower normal running noise. Individual subjective impressions in certain applications are not displayed because the SGI refers to reference conditions that describe the load case, mounting as well as assessment.

Because the SGI is normalized, it does not have a separate unit. In the catalog listing, it is displayed graphically over the static load rating C0, which offers a fast and clear overview for a given application with known load rating. The relationship to C0 is obvious as this measure links the maximum permissible load to a certain plastic deformation, which may be directly related to the emitted vibration.

The Schaeffler Noise Index is available for the main series of deep grove ball bearings, angular contact bearings as well as tapered and cylindrical roller bearings. It allows quick comparisons to be made between different bearing types, e.g., ball bearing vs. roller bearing. An SGI for additional bearing types and series is currently in development and will be published as it becomes available [3]. Fig. 5, which features a graph of the SGI for deep groove ball bearings, clearly shows that several bearing series may be used for a given C0 = 20300N. Furthermore, the graph shows that, depending on the geometrical dimensions of the application, one particular bearing series provides the best fit (for example, the 62..-C series). For noise-sensitive applications, Schaeffler’s GenerationC bearing (designated as point 2 in the graph) is recommended because its SGI value is considerably lower than for a conventional version (designated as point 1).

Schaeffler Noise Index

Summary

To address the challenges posed by the noise behavior of rolling-element bearings, it is necessary to take a comprehensive approach that includes advanced simulations, testing methods and readily available rating values. This article provides examples of validated multi-body-simulations that help to understand the general excitation mechanisms within bearings in order to be able to optimize them during the design phase.

To that end, Schaeffler has introduced its Schaeffler Noise Index, which allows the noise emitted by a bearing at reference conditions to be quickly and easily rated. As such, the SGI offers a hands-on rating tool for designers during the application engineering stage.

Compact Gearboxes: All Clear for Automated Guided Vehicles

Compact Gearboxes: All Clear for Automated Guided Vehicles

Automated guided vehicle (AGV) systems can increase efficiency in production and logistics. To do so, however, they have to be powerful, safe and flexible. ABM Greiffenberger presented a series of extremely compact and space-saving gearboxes designed specifically for use in automated guided vehicles. They enable reliable and energy-efficient operation on factory floors and in warehouses.

ABM offers efficient gearboxes for various vehicle concepts. These include towing vehicles, undercarriages, upgraded forklifts and assembly platforms. ABM  developed particularly compact parallel shaft and angular gearboxes, which can be easily integrated into the often tight spaces of automated guided vehicles.

The two- and three-stage units are available with high reductions, low backlash and high encoder resolution. They are designed for low speeds and enable exact vehicle positioning. Different steering versions are used depending on the drive unit design, e.g., via electronic differential control of two motors for curved paths. For complex driving maneuvers, forward and backward motion, lateral travel or rotation when stationary, one or more drive wheels can be steered electrically.

KG series bevel gears with output torques of 60 to 800 Nm are included among the versions that are particularly well suited to use in AGVs. FG series parallel shaft gearboxes range from 50 to 2,000 Nm. ABM also has helical gearboxes in its portfolio with output torques ranging from 30 to 2,080 Nm. High wheel loads of up to 25,000 N are provided by hub wheel drives (TDH series) offered in four versions with output torques from 360 to 2,000 Nm and of robust design. Through the integration of the components into the drive wheel, the ABM designs excel as traction drives with particularly efficient, space-saving force transmission. Bevel gear drives type TDB can be supplied with electric steering upon request. They are available with static wheel loads of up to 16,000 N and in the different versions cover a range from 435 to 2,000 Nm. Type TDF parallel shaft gearboxes with a performance range of 435 to 1,400 Nm reach static wheel loads of up to 17,000 N.

The high wheel torques at low rotational speeds facilitate traveling on slight inclines and enable precise maneuvering. Additionally, users save costs: Thanks to the high wheel loads, there is no need for separate support of the wheel axle.

SINOCHRON® Motors for Long Battery Life
Compared with forklift drives, automated guided vehicles do not require high starting torques for inclines because they are usually used on level factory floors. Autonomous operation batteries with 48 or 24 volts are frequently used. Permanent-magnet synchronous motors have proven themselves in low-voltage applications and are recommended for use here. ABM offers the SINOCHRON® series with a continuous output of up to 13 kilowatts for this use. This series is characterized by its compactness and high efficiency. SINOCHRON® Motors are environmentally friendly. They surpass the requirements of Super Premium Efficiency class IE4. Users can meet future legal regulations with these advanced standards. The drives possess a high power density and provide for long battery life in daily use. In addition, the series is compact and can easily be integrated into transport systems.

Permanent focus on customer benefit
ABM Greiffenberger is present in the AGV sector as a system supplier who offers a high-level of customer support, development expertise and turnkey solutions: all products are designed in-house, and even complex prototypes can be quickly produced via additive manufacturing. Modern testing technologies and a laboratory for materials analysis and motor dynos ensure consistent high quality. The parts are produced on state-of-the-art machines and machining centers; robot-controlled manufacturing cells guarantee consistent series quality. Innovative products arise out of close customer relationships and intense market monitoring. ABM uses its modular and extensive portfolio to develop application-tailored, space- and cost-optimized systems.

Choosing a Gearbox Drive and Electric Motor Supplier

When choosing manufacturing partners during a machine build, remember that there are two methods for choosing a gearbox and electric motor supplier. One is selecting a pre-engineered unit and the other is choosing a gearbox-motor combination and integrating them into the equipment.

Pre-engineered gearmotor solutions are suitable if a design engineer doesn’t have the time or engineering resources to build a gearmotor in-house — or if the design needs a quick setup. New modular approaches to support OEMs (and enable new machine tools, automation, and design software) now let engineers get reasonably priced gearmotors even in modest volumes.

It’s true that one benefit to selecting a separate motor and gearbox and then combining them can less expensive than choosing a pre-engineered gearmotor. Another benefit to this approach is that one may be able to design the most optimized gearmotor for the application at hand … because this approach also gives the design engineer the most control over the final configuration and cost.

No matter the approach to gearmotor selection, be sure to continually improve the design by comparing predictions of performance with measurements. Then use the result of the analysis to improve next gearmotor iteration.

ABM Offers Energy-Efficient, Liquid-Cooled Motors for Long Operation

Liquid-Cooled, Energy-Efficient Gearbox Motors

Efficient Drives for Various Industries

ABM DRIVES INC. added liquid-cooled motors to their comprehensive program of efficient drive technologies for various industries. This motor excels with high power density at minimal space requirement, energy efficiency and long operating time.

Liquid-Cooled, Energy-Efficient Gearbox Motors
The liquid-cooled motors are suitable for a variety of industrial applications as well as mobile applications.

Users can reliably operate this motor over a long period with high output devoid of overheating. ABM DRIVES INC. offers these motors in IEC frame sizes 80 to 160. Outputs up to 100 kW are feasible and if required they can be easily controlled with ABM inverters. Additionally, it is possible to set a constant operating temperature resulting in uniform elongation. This means the motor can be fitted in µ-accuracy in its application – an advantage that considers the ever-increasing demand for smaller space requirements.

Depending on the application or customer needs, cooling can be accomplished by water, oil or refrigerant. Radial cooling results in an extremely efficient motor but axial cooling is simpler in design. Liquid-cooled motors can be combined with ABM straight shaft, parallel shaft and right-angle shaft helical gearboxes. The user can pick flexibly from the complete ABM drive portfolio. The motor lends itself for industrial applications such as textile machinery but also for mobile uses such as construction machinery. In addition, they impress in powerful electro vehicles and watercraft.

ABM presents itself as a systems supplier that can deliver complete drive solutions from a single source. The company takes over full systems responsibility from specification to manufacturing. In addition, the specialists from the town of Marktredwitz deal with the systems integration, so customers receive solutions with additional benefits. ABM makes sustainability an important consideration in the strategic direction through an emphasis on the protection of resources, high energy efficiency and minimal emissions during operation.

Straight shaft, parallel shaft and right-angle shaft helical gearboxes combined with ABM motors can also be supplied industry and application-specific with inverters. They are equipped optimally with different bus systems and guarantee network interconnectedness. This prepares the ABM drives system for the Industry 4.0 requirements.

What is Droop Control in the Context of AC Motors & Drives

AC Gear Motor Droop Control Conveyor

What is Droop Control in the Context of AC Motors & Drives

One of the fundamental characteristics of an AC induction motor is that the rotor spins at a slower rate than that of the stator’s rotating magnetic field. This difference in speed between the rotor and the stator’s magnetic field is known as slip.

Slip allows the motor to produce torque — the higher the slip, the higher the torque production, but also, the lower the motor’s efficiency (in most cases). But in load-sharing applications, motor slip can be used to prevent one motor from taking a disproportionate share of the load.

Slip = (Ns – N)/Ns

Ns = synchronous speed (rpm)

N = rotor speed (rpm)

Load-sharing, in this context, refers to two or more AC motors connected to and driving the same load. Read More.

Natural Load Balancing

Because slip is inherent in AC motors, when two or more motors are connected to one drive, their natural slip will work to achieve balanced load sharing. As one motor experiences increased load, its speed (i.e., rotor speed) slows down, increasing slip between the rotor and stator. Read More.

Droop Control

For applications where load-sharing needs to be precise and controllable, some AC drives include a function — typically referred to as droop control — that manipulates motor slip to better ensure equal load-sharing. Read More.

AC Gear Motor Droop Control Conveyor

Droop control is often used to increase slip in an overloaded motor, allowing other motors connected to the same load to take a higher share of the load. One application where droop control is useful is a conveyor with multiple driven rolls. If one section of the conveyor (and, therefore, one motor) sees an increase in load, droop control prevents the motor from sustaining this disproportionate share of the load, preventing damage to the motor and, potentially, to the system.
