Uhing Rolling Ring Drives are non-positive drives that convert the rotation of a smooth, non-threaded round shaft into a linear movement. Rolling ring bearings are arranged at an angle to the shaft and press against the rotating shaft with their specially shaped running surfaces. Depending on the swivel angle, they generate a left- or right-handed movement. The pitch can be finely adjusted, right up to standstill.
The main advantages of the Uhing® rolling ring drive are:
- Highest efficiency: Gear and payload are fully supported by roller bearings.
- Automatic traversing movement.
- Variable traversing speeds (0 m/s to 4.2 m/s); separately set for both directions with constant shaft rotation.
- Adjustable traversing width and position.
- High dynamics at points of reversal.
- Can be released from the shaft.
- Low operating costs.
- Low maintenance requirements.
- Operate like nuts on a screw rod with adjustable right-handed or left-handed pitch (can equal zero).
- Achieved via pivoted Uhing® rolling rings mounted on roller bearings, with a specially shaped running surface pressed against the rotating shaft.
- Roller lever contact with cams along the stroke path allows for complex motion patterns.
