Virtual End-of-Line Test

Tooth contact analysis is an integral part of the gear design process. With the help of these simulation tools, it is possible to calculate the excitation caused by a tooth contact (Ref. 1). Usually, the load-free transmission error or the total transmission error under load is used for this purpose. However, the calculation with the tooth contact analysis ZAKO3D allows only a quasi-static consideration of the excitation. To better evaluate the behavior in the overall system, it is therefore necessary to perform a dynamics simulation. However, the main disadvantage of such dynamics simulations is the much longer computing time compared to quasi-static tooth contact analyses due to the high computational effort.

Understanding Cycloidal Gearboxes - Single-stage vs Multi-stage

It's no secret that cycloidal gearboxes are important in mechanical engineering, especially when it comes to precision motion control and efficient power transmission. The gear systems differ from harmonic wave/strain wave gearboxes by using a cycloidal disk and needle bearings to transmit torque with minimum backlash, achieve high reduction ratios, and support substantial loads. This Sumitomo Drive Technologies blog will talk about single-stage and multi-stage cycloidal gearboxes.

Use of Gear Reliability Data in a Cloud-Based Gearbox Digital Twin Using Telematics Data

For this paper, the digital twin refers to a digital asset that exists alongside the physical asset during its operational life, providing insight into and feedback on the physical asset’s performance and health. Thus, the focus is on the DTI, with the potential to aggregate data into a DTA for the gearbox design being considered, and within the DTE set up by Hexagon.

In respect of the physical asset across its life, nothing is more important about its performance than its ability to function, i.e., reliability, and for CAE, nothing is of greater importance than to be able to predict the reliability of a product being designed. Thus, for this study, whilst gearbox noise, efficiency, and thermal behavior may be of interest, the primary interest is fatigue and reliability.

Redex Differential Gearboxes Ensure Lay Consistency for Wire Bunching Equipment

When it comes to twisting and bunching wire and cable, consistency is key. For example, the amount of insulation required for residential wiring depends on the wire’s lay — the distance between its twists, which is also known as the pitch. Without tight control during the wire bunching process, lay variations occur. As a result, the wire will require more insulation than necessary, raising its cost. A differential gearbox can drive rotating components in a single-twist buncher to provide a more uniform lay, using less power at a lower cost than a two-motor approach.

Fact or Fiction?

In everyday life and in the technical fields we often discover that certain decisions are based on “scientific data” when, in fact, they are often founded on historic conclusions that have not been challenged or re-evaluated in a long time. One such common myth is that for a stable and well-tuned drive you should match the motor’s inertia to the load inertia, which is typically done using a gearbox. Two factors lead to that conclusion: a. there is an optimization formula using the time constant of the motor and the load torque that shows that the best acceleration will be achieved if the reflected load inertia matches the rotor inertia; and b. a PID controller, which was commonly used when electric servos entered the marketplace, tend to perform best and appear to be most stable when the inertia are close or matched.

Precision Coupling Basics—Stiff or Stiff Enough?

Precision flexible shaft couplings come in two basic forms, both of which are designed to operate without backlash or excessive inertia while compensating for inevitable misalignment offsets between motor/gearbox and load. Torsionally stiff couplings are made with metallic flexible elements and with the intent to eliminate as much twisting deflection as possible so that the rotation of both shafts is kept as well synchronized as can be.

The Flexibility Factor

A flagship coupling in the Huco range, the Oldham solves the problem of side forces due to misalignment. Misalignment couplings that bend or flex do cause some side loading on bearings and shafts as the coupling tries to spring back. Of course, over prolonged use this can result in rapid deterioration of bearings, extra load on the motor, and eventual coupling fatigue.

Preventing unplanned downtime in industrial processes only gets more important during times of high demand. The cost of gearbox, motor and drive shaft replacement often pales in comparison to that of the lost production resulting from mechanical torque overload failures caused by jams, collisions and binding in the driveline. This makes mechanical circuit breaking technology more important than ever since a fast, tool free reset and recovery from torque overload minimizes interruption.

Bearing Lubricant Solution

A Chicago-area bakery was replacing the tray support bearings in its ovens on a reactionary basis. Their weekly inspection cycle was resulting in two mechanics spending an average of 20 labor hours per week to replace failed bearings. The premature bearing failures were caused by a combination of the high heat and humidity in the ovens, resulting in lubrication failure and contamination. When BDI was asked to recommend a solution, the bakery was averaging one month of bearing life in this application.

The Importance of Thermal Protection for Torque Motors

When talking about high-end machining or manufacturing applications that include direct-drive technology, one of the key advantages of utilizing this particular transmission method is its endurance. Because of the very nature of direct-drive motors they are able to operate at peak performance levels indefinitely — without any kind of wear or aging — as long as the motor isn’t pushed past its capacity. Unfortunately, because this isn’t a perfect world, unexpected things can happen which can cause the motor to overheat. Whether the heat source is due to a parameter being input incorrectly, or an unexpected external force causing more resistance than expected — it is important to have certain forms of thermal protection in place. Since torque motors are built in such a way that they cannot be repaired and yet maintain their efficiency, it is vital to prevent any overheating — thus precluding the need to purchase a new one.
