Rolling-Ring Drives
Uhing® Rolling Ring Drives are friction drives which convert the constant rotary movement of a plain shaft into a traversing movement. They operate like nuts on a screw rod but have a pitch - either right-handed or left-handed - that can be precisely adjusted and can equal zero.
This effect is achieved by using pivoted Uhing® Rolling Rings that are mounted on roller bearings and have a specially shaped running surface which is pressed against the rotating shaft. A roller lever capable of making contact with cams arranged along the stroke path makes it possible to implement even complicated patterns of motion.
