Abstract
RV reducer has a wide range of applications in China due to a series of advantages such as high precision (backlash less than 1 Angle minute), high rigidity, high durability, high output density (strong torque & compact), wide reduction ratio range and low vibration. Due to the large gap between domestic RV reducer and foreign brands, this is mainly reflected in the low level of research and low investment due to low profitability, the domestic RV reducer market relies heavily on imports at present. By reviewing the development status of RV reducer at home and abroad, this paper points out the restrictive factors in the development of domestic RV reducer, the number of patents filed as the main measure for assessing the level of research in China and abroad, and puts forward suggestions and directions for the development of domestic RV reducer, providing reference for the next development of domestic RV reducer.
