Product Principle：
Rolling ring traverse drive 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 Drives 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 Rolling Ring Traverse Unit Principle ：
Rolling Ring Traverse drives Working are non-positive drives which convert the constant rotation of a plain round shaft into reciprocating motion. They operate like nuts on a threaded bar, however the pitch both left-hand and right-hand can be fine-tuned or set to zero. This effect is achieved by using ball bearing based Rolling Rings which are designed to tilt on the shaft, their specially crowned running surfaces being pressed against the shaft as it rotates.
The main advantages of the Uhing rolling ring Unit 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
