Roller Pinion Systems
The Roller Pinion System (RPS)is based on an innovative pinion consisting of bearing-supported rollers and a unique tooth profile.
This unique drive system provides very high positional accuracy, near-zero backlash, virtually no cumulative error, low-velocity ripple, unlimited length, very high speeds, high rigidity, low noise, low (in some cases no) maintenance, corrosion resistance, long life, and 99% efficiency.
This opens up new machine design possibilities and provides the capability to achieve much higher levels of performance.
High Positional Accuracy
Positional accuracy up to ± 30 microns and repeatability of ± 5 microns at its meshing line or circle.
Near-zero backlash of less than 3.2 microns is achieved by multiple rollers engaging the rack or gear teeth in opposition at all times.
Typical Product Use
A few areas where you can find these products in use are listed below:
- Mechanical Testing Equipment
- Welding Systems
- Production Workcells
Capable of speeds as high as 11 m/sec. Extemely low friction design does not create heat or significant wear on components.
We use needle bearings to support the rollers that engage the teeth. This eliminates the sliding friction found in many other motion control systems and gives it an efficiency greater than 99%.
