Wind power speed reducer

Abstract

A wind turbine reducer, relating to the field of wind power equipment technology, is used to solve the technical problems of high processing cost, difficult operation, and low precision in existing technologies. In the wind turbine reducer, the upper body, the first steel tube internal gear ring, and the support base are connected by the first bolt; the support base, the second steel tube internal gear ring, and the lower body are connected by the second bolt. Because the production process of the steel tube internal gear ring is relatively simple and is usually mass-produced, material procurement is relatively stable, and its price is lower than that of forging materials, thus effectively reducing material costs. At the same time, compared to forging materials, it saves the cost of mold making, and the internal microstructure of the steel tube internal gear ring has a uniform grain distribution, resulting in stable mechanical properties and effectively simplifying the processing flow. Furthermore, the design of the steel tube internal gear ring can be applied to wind turbine reducers of different specifications and types, thus having wide applicability and being suitable for various specifications.
