HIGH-RATIO DRIVE MECHANISM

摘要

A rotary power transmission having a drive shaft and a driven shaft in parallel or coaxial alignment, a rigid annulus fixedly mounted around the drive shaft, the driven shaft having a flexible tubular end portion disposed between the drive shaft and the rigid annulus, and means including rollers between the drive shaft and flexible tubular end portion for transferring torque from the drive shaft to the flexible tubular end portion by frictional circumferential engagement and radial compression of the tubular end portion between the rollers and the rigid annulus.
