Abstract

The invention discloses a wind power gear box transmission structure which comprises an impeller and a box body. The impeller is arranged on a convex neck outer ring of the box body through a bearing;the side edge of the impeller is connected with a main shaft through a hub coupler; the main shaft penetrates through a convex neck of the box body so as to stretch into the box body; a planet carrier is connected to the tail end of the main shaft and is supported on an inner wall of the box body through a bearing; a drive bevel gear is arranged on the main shaft close to a front side wall of thebox body and is in transmission connection with a driven bevel gear through a duplex bevel gear; the duplex bevel gear is arranged on an inner wall of the tank through a bearing; the driven bevel gear is fixed onto an inner gear ring; a planet wheel in the planet carrier meshes with the inner gear ring, stretches out of a roller outside the planet carrier through the bearing so as to mesh with asun wheel; and a sun wheel axle stretches out of a rear side wall of the box body so as to externally output the torque. The wind power gear box transmission structure provided by the invention has the technical effects that the transmission ratio is improved, so that an operation performance, the generating capacity and the generating efficiency of a fan are improved.

Description

technical field [0001] The invention relates to a planetary transmission structure of a wind power gearbox, belonging to the technical field of new energy equipment. Background technique [0002] With the increasing saturation of hydropower generation worldwide and people's increasing attention to climate change, the environmental pollution problems caused by fossil fuels and solar energy technologies have seriously restricted their own development. As a clean and cheap renewable resource, wind energy has a total reserve of 40 times the current global energy consumption in the world, which to a certain extent has promoted the continuous growth of the total installed capacity of wind power. In recent years, with the continuous improvement of modern manufacturing level, material industry and other fields of science and technology, in order to improve the efficiency of wind power generation and reduce the cost of power generation, wind turbines are developing in the direction o...
