Whitepapers, Articles and Power Transmission Tips from our Engineers
This paper will provide recommendations and ideas for obtaining a highly efficient gearbox while still taking into consideration application constraints.
In industry, digital prototyping has become a valuable tool for the design and subsequent analysis of components for a proposed design. It is not common to find dynamic examples of the operation of a cycloidal type speed reducer where the kinematics of the reduction mechanism is completely different from that of the traditional involute gearing. The paper explores a method of dynamically simulating a cycloidal type speed reducer where the generated internal loads are used to assess the stresses acting on the one of the major reduction components contained within the cycloid disc.
Can lubricants improve gearbox efficiencies? This paper will explore how oil selection can affect gearbox efficiency.
This paper provides basic lubrication information for industrial gearbox oils and examples of specific recommendations for Sumitomo Drive Technologies' products. Basic properties, terms from specification sheets and maintenance information are also included.
In this article we will provide a few tips to extend the time between the major life periods of the average gearbox. There may be significant differences between new, broken and rebuilt gearboxes, but they all have certain maintenance requirements in common.
This paper provides some design guidelines for torque arm applications in shaft mounted speed reducers.
This paper will review ways in maintaining and managing automotive equipment for trouble-free operation.

Methodology for Identifying Defective Cycloidal Reduction Components Using Vibration Analysis and Techniques
This paper explains how gear efficiencies are just as important as motor efficiencies if you want to improve the overall system efficiency of your application.
Sumitomo Drive Technologies is working on a design of the alignment free system by using Finite Element Analysis (FEA) to help guide the design process.
The goal of this analysis is to provide a technical understanding of the cause(s) of failure, its consequences, and a means to correct any problems with the gearbox - real or perceived in WWT Aerator Drives.
Learn about the different methods of shaft-mounting a reducer that include keyed, splined, taper grip bushing, shrink disc and rigid coupling.
Sumitomo's Cyclo Centrifuge Drives are used to separate liquids from solids through either a decanter or screen centrifuge
Sound can be a very subjective thing. What may sound “unusual” to one individual may very well sound “normal” to another. As a method of diagnosing a potential problem with a gearbox or gearmotor, the sound coming from it should not solely be relied on to determine whether a problem exists.
Selecting the right gearbox for your mixer application is important - especially when it is also the key support between the impeller shaft and the motor.
One of the most cricical aspects to consider when sizing and selecting a gearbox is the required service factor. Learn how to determine the proper service factor for overhead crane applications.
This paper discusses the stress distribution, modeled in a dynamic simulation environment, on the rotating parts of Cycloidal reducer. A three dimensional finite element model is developed using Algor FEA commercial code to simulate the combined effect of external loading and dynamic as well as inertial forces on one--cycloid disc system.
