Planet carrier floating structure of wind power generation yaw and variable pitch speed reducer

Abstract

The invention relates to a planet carrier floating structure of a wind power generation yaw and variable pitch speed reducer. The planet carrier floating structure comprises a planet carrier, a sun gear matched with the planet carrier through a spline and a planet gear installed on the planet carrier. A supporting pad is arranged at the end, in spline fit with the planet carrier, of the sun gear, the supporting pad is fixed to the planet carrier through a shaft clamping spring, the shaft clamping spring is installed in a clamping groove formed in the planet carrier, the shaft clamping spring, the supporting pad and the planet carrier form a whole, and the spline of the and the planet carrier are modified to be in a drum shape in the tooth direction. The spline fit tolerance of the sun gear and the planet carrier is controlled to be 5f / 6H, so that the floating structure is formed, the axial and radial floating amounts are achieved, the effective error compensation amount is provided during operation of the speed reducer, the bearing capacity is improved, the service life of the speed reducer is prolonged, and the problem that due to the fact that an internal planet carrier assembly of an existing wind power generation yaw and variable pitch speed reducer is an integral rigid assembly, and consequently, a tooth surface is prone to generating abnormal abrasion is solved.

Description

technical field [0001] The invention belongs to the field of mechanical transmission, and relates to a planet frame floating structure of a wind power generation yaw and pitch reducer. Background technique [0002] At present, when the yaw and pitch reducers are working in the industry, as the wind direction changes, the yaw and pitch reducers adjust the windward angles of the nacelle and blades respectively, so that the wind turbine can maximize the use of wind energy. At present, the internal planetary frame assembly of the yaw and pitch reducer is an integral rigid assembly. During assembly, a circlip is used to fix the position on the upper surface of the sun gear. The free floating of each level, because the planets of each level use multiple planetary gears to mesh with the ring gear and the sun gear at the same time, there are errors in gear processing, ring gear processing, assembly, etc., so this structure affects the spline when the reducer is running. , Sun gear,...
