Nexen Roller Pinion System Opens Up New Design Possibilities
Nexen Group’s unique new Roller Pinion System (RPS) revolutionizes linear and rotary motion.
The Technology
The RPS allows machine designers to incorporate highly accurate linear and rotary motion-control functions with zero backlash and speeds as high as 11 meters per second (36.1 feet per second).
The incredible performance of the Roller Pinion System is controlled by the innovative way in which the roller pinions engage the linear toothed track or the ring gear. The roller pinions follow the profile of the specially shaped teeth in such a way that two or more rollers connect with the rack teeth in opposition at all times, offering backlash-free performance in both directions with no cumulative error.
The typical life of the Roller Pinion System is estimated to be as high as 28,000,000 meters of travel (94,000,000 feet). Linear track sections can be joined together to total any reasonable length with no sacrifice in accuracy. In addition, the ring gear can be manufactured in segments that can be joined together to create large diameters with no loss of precision.
The Applications
The patented RPS technology can replace typical rack and pinions, linear motors, spur gears, chain/belt drives and ball-screws in critical motion-control applications that require high speed, great accuracy, and low maintenance and noise.
The Benefits
The RPS provides zero backlash, very high positional accuracy, unlimited length or diameters, very high speeds, 99% efficiency, high rigidity, low noise, low maintenance, corrosion resistance, and long life. The RPS system is capable of positional accuracy up to ± 30 μm [± 0.00118 in] and repeatability of ± 5 μm [± 0.00020 in] over any run length. This opens up new machine design possibilities and provides the capability to achieve much higher levels of performance in machine designs.
