RV-C


Hollow shaft component sets

Powerhouses with an open centre

RV-C gears are your ideal choice for very demanding applications. They have a hollow shaft through which power supply cables, drive shafts, etc. can be fed. The RV-C component sets are compact, lightweight and offer high torsional and moment rigidity. Thus, the RV-C gear series reaches exceptional repeatability and path accuracy.

Hollow shaft (for routing cables, etc.)

High precision (hysteresis loss < 1 arcmin)

Less vibration

High precision for diverse application options

The component sets of the RV-C series have an identical design and the same quality characteristics of the RV-E eccentric gears. The difference is the hollow shaft with a diameter of up to 138 mm.

The design of the RV-C component sets achieves very high repeatability and path accuracy with a hysteresis loss of less than 1 arcmin. In combination with the low vibrations, the RV-C series is therefore ideal for applications in robotics, medical technology, 5-axis machining centres (CNC) and also for antenna systems, which require maximum precision.

Applications for RV-C hollow shaft component sets

Robotics

Delta, SCARA and 6-axis robots for painting systems, assembly, PCBs and machine tools

Medical technology

Imaging processes such as X-ray, MRI or ultrasonic examinations

Antenna construction

Adjustment of large parabolic antennas for communication with near-Earth satellites
