Rolling ring drive
The Uhing® rolling ring drive principle
Download rolling ring drive catalogue
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 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

60 Years Uhing Rolling Ring Drive, or “Archimedes’ Dream”
This may well have been the dream of the mathematician Archimedes (278 to 212 B.C.) and his contemporaries: Since Ancient Greek times, there has been the desire for a helical gear variable in terms of pitch and direction. Electrical engineer Joachim Uhing made this dream come true by inventing the rolling ring drive. In 1952, he launched the first version of this device. This year, Joachim Uhing KG celebrates the 60th anniversary of its renowned product....[read more]

Traversing system automatically ensures a cylindrical winding
To obtain a cylindrical winding in the particularly critical reversing area, Uhing has developed the AVS Traversing Width Controller that does not require any interference-prone optical sensors.
