I bet a lot of us (mentors and students) got into this line of work first because we wondered how things work, and stayed in it because we thought "I can make that work better". Thus starts a life-long battle between perfection and time. So far, time is ahead. - petek [more]
Description:
The Who'sCTEKS present their 2004 Dual Speed Dual Motor Gearbox. This design is a refinement of their 2003 Dual Speed run during the 2003 off-season. It uses the CIM and Bosch Motors and can be built as a single motor gearbox.
Team 716, the Who’sCTEKs would like to share our 2002 dual motor gearbox design. The drawings are in AutoCAD R14 and are in a self extracting zip file. This shows a simple way to couple two motors using gears and sprockets. Key factors are shaft center distances and matching motor speeds.
