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

Uhing Drives Antarctic Research
Operating in one of the harshest environments on the planet, The British Antarctic Survey (BAS) has, for over 60 years, undertaken the majority of Britain’s scientific research on and around the Antarctic continent. A component of the Natural Environment Research Council, BAS supports three permanent research stations based in Antarctica, along with two stations on South Georgia and is at the forefront of research on “the frozen continent”, work that recognises that “the Polar Regions may be at the ends of the Earth but what happens there affects us all”....[read more]

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]

Uhing at Wire 2012 in Düsseldorf
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. The traversing system used here is the well-known Uhing rolling ring drive featuring pneumatically controlled reversing triggered by a microcontroller.....[read more]
