Description
technical field [0001] The invention belongs to the technical field of yaw reducer for wind power generation, and in particular relates to a yaw reducer with multi-shaft combination drive of planetary gear plates for wind power generation and small tooth difference. Background technique [0002] Most of the yaw reducers currently used are driven by multi-stage planetary gears. If the required large transmission ratio (i=1000-4000) is realized, the axial dimension will be relatively large. Due to the limitation of space size, the load borne by multi-stage planetary gear transmission is limited, which makes the life of the yaw reducer currently used is relatively low. [0003] In order to reduce the axial size and improve the load-carrying capacity of the output end, some literatures have proposed transmissions with few tooth differences using different stages and tooth shapes, which solve the above problems to a certain extent. Such as: [0004] Deng Hao, Gui Peng. Yaw redu...
