VRG hub reducer has the characteristics of large bearing torque, low noise, stable operation, short length and maintenance-free. The integrated processing of high-speed end support and gear meshing can better realize the requirements of coaxiality and meet the requirements of low noise; An adjustment ring is added inside the reducer, which can adjust the internal axial clearance to achieve channeling; The output end of the reducer is carried by tapered roller bearings to meet the demand for greater force and the stability after loading; Parts processing quality: the core components of the reducer are realized "professional people do professional things, professional enterprises do professional parts", the external teeth are hard scraped, the internal teeth are broached multiple times, and all parts are fully inspected by the quality management system and assembled by classification. The appearance of the product is handicraft: the appearance of the shape adopts a combination of curved and straight to meet the aesthetic needs; The outer surface treatment adopts a specific process and is tested by salt spray to achieve anti-corrosion and anti-rust.
