Mechanical design engineers planning a drivetrain typically have a range of component options to choose from, and many decisions will boil down to the specific application. When it comes to creating optimal torque output, rotational speed and direction, few decisions are as important in designing high performing gear drives as choosing the right gear for the job. 

The Timken Company has agreed to acquire CGI Inc., a Nevada-based manufacturer of precision drive systems serving a broad range of automation markets with a concentration in medical robotics. The deal is subject to customary closing conditions, including regulatory approval, and is expected to close in the third quarter.

Verification of a drive system should include all main elements of the system, which are gears, bearings, shafts, and depending on the application other parts such as screws, couplings, and connections. Gears are clearly the most complicated parts for verification, but in many cases, a gearbox failure has its origin in a shaft or bearing failure. The subject of this paper is to explain how verification of a drive system based on measured or simulated torque-speed-time data can be handled.
