Principle of CRP Zero-Backlash Roller Rack：
-
The roller system is composed of multiple rollers mounted on a roller frame. During engagement, the rollers roll along the rack’s tooth surfaces, significantly reducing friction, enhancing meshing precision, and minimizing wear. Moreover, the tooth profiles of both the rack and the gear ring are engineered based on the rollers’ unique rolling characteristics—distinct from the conventional involute design—to ensure superior meshing performance.
Features of the CRP Zero-Backlash Roller Rack:
-
Zero Backlash：The engagement between the rollers and the rack (or gear ring) achieves zero backlash, allowing for the application of preloading that substantially enhances both repeatability in positioning and transmission precision.
-
High Precision：Delivering transmission accuracy up to ±0.02 mm, repeat positioning accuracy of ±0.01 mm, and angular precision as fine as ±50 arc-seconds—comparable to that of lead screws.
-
Low Noise & Vibration：Designed to accommodate a wide range of loads, with no differential vibration between no-load and full-load conditions.
-
Long-Distance Transmission：Thanks to its modular, splicable design, the rack enables extended precision transmission—far surpassing lead screws—while also allowing for custom arc configurations.
-
Extended Lifespan：The rolling engagement markedly reduces wear compared to conventional gear racks, ensuring that the angular transmission via the circular-ring rack maintains high precision and torque over prolonged use.
-
ltra-Low Friction & Noise：Featuring a specialized tooth profile that minimizes dust generation, this design is ideally suited for Class 1000 cleanroom environments.
-
Versatile Input Options：Offered in various configurations and fully compatible with SAIZIN reducers.
