Traction Drive Unit Reducer for high-accuracy feeding Minimal rotation irregularity No backlash Low noise, low vibration

The traction drive unit is a power transmission based on the rolling contact between rollers and is capable of smooth, rattle-free power transfer. High-accuracy and high-strength rollers are subjected to elastic deformation prior to assembly, achieving high pressure force. Additionally, by introducing traction grease that becomes highly viscous under high pressure, it is possible to achieve excellent power transfer while securing lubricity. Principle and Structure Traction force T (rolling transfer force) Traction force T=pP ^Traction coefficient P:Pressure force Ideal for High-accuracy Feeding...
