UHING Rolling Ring Drives

Product Overview

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 patters of motion.

The main advantages of the Uhing® rolling ring principle are:

  • highest possible efficiency due to the fact that the gear and the payload are completely supported by roller bearings
  • automatic traversing movement
  • variable traversing speeds ranging from 0 m/s to a maximum of 4.2 m/s; can also be separately set for the two directions with constant rotation of the shaft
  • variable traversing width and traversing position
  • high dynamics at the points of reversal
  • can be released from the shaft
  • low operating costs
  • low maintenance requirements
