Abstract

The invention relates to the technical field of wind power generation, in particular to a wind power generation speed reducer which comprises a mounting table, a speed reducer body and a base fixedly connected to the speed reducer body, a placing groove is formed in the mounting table, and the base is fixed in the placing groove through a locking mechanism; the locking mechanism comprises a torsion bar, the torsion bar is rotationally connected with the mounting table, a worm and a gear are fixed to the torsion bar, a worm gear meshed with the worm is rotationally connected into the placing groove, a locking block is fixedly connected to the worm gear, a sliding groove is formed in the placing groove, a rack is slidably connected into the sliding groove, and the rack is meshed with the gear; and an oil outlet in the upper end of the speed reducer body is communicated with a filtering module. The locking block and the rack are used for right-angle clamping of the top wall and the side wall of the base, the effect is reliable, operation is convenient, and the efficiency is high; and the filtering module is used for filtering oil liquid, abrasion of parts in the speed reducer is reduced, and the service life of the speed reducer is prolonged.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a speed reducer for wind power generation. Background technique [0002] The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator. The reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. According to the number of transmission stages, it can be It is divided into single-stage and multi-stage reducers; according to the shape of the gear wheel, it can be divided into cylindrical gear reducers, bevel gear reducers and conical-cylindrical gear pulley reducers, which are often used as reduction transmission between the driving part and the working machine The device plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator, which is very common on wind turbines.
