Problems solved by technology

However, since the wind speed of offshore wind farms is much higher than that of land wind farms, the equipment is required to be highly reliable, easy to install, and easy to maintain. Therefore, the yaw reducer commonly used in wind power generation cannot be applied to the offshore wind power industry.

Embodiment Construction

[0021] The large-torque wind power generation yaw reducer of the present invention comprises a motor 14, a motor base 12 is installed under the motor 14, and an organic casing is installed on the motor base 12, and the casing is composed of an upper body 16, a support body 121, a support body II23 and lower body 26. The middle part of the motor base 12—the central axis of the motor main shaft is provided with a socket 13, and the bottom of the socket 13 is sequentially connected with a five-stage planetary gear set. Each stage of the planetary gear set is composed of a sun gear in the middle part, a planetary gear installed around the sun gear and meshed with it, a planetary carrier supporting the planetary gear, and an internal gear. The number of planetary gears is generally 3-4, evenly Distributed around the sun wheel. The internal gears of the first, second and third stage planetary gear sets are integrated with the upper body 16, the internal gears of the fourth stage pl...

Abstract

The invention relates to a large-torque wind power generation yaw speed reducer. The speed reducer comprises a motor and a machine shell connected with a motor seat below the motor, the large-torque wind power generation yaw speed reducer is characterized in that five-stage planetary gear sets are sequentially connected and mounted in the machine shell along the central axis of a motor main shaft,wherein a fifth planetary carrier of a fifth-stage planetary gear set and an output shaft are transmitted through a spline, and the output shaft and an open gear below the output shaft are of an integrated structure. The large-torque wind power generation yaw speed reducer has the technical advantages of being compact in structure, stable, large in torque, high in transmission efficiency, low incost and the like, and is suitable for offshore wind power generation.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a large-torque wind power generation yaw speed reducer. Background technique [0002] Wind power is the fastest growing new energy source in the world. Among them, offshore wind power has become a wind power because of its advantages of no need for fuel, no occupation of cultivated land, no pollution, low operating cost, and no radiation or air pollution. The mainstream of power generation. [0003] my country is rich in wind energy resources, and the wind energy reserves that can be developed and utilized are 1 billion KW, of which the wind energy reserves on land are about 253 million KW (calculated at a height of 10m above the ground on land), and the wind energy reserves that can be developed and utilized at sea are about 750 million KW. Now the onshore wind farm is limited, and the high-power wind turbine yaw reducer is still under development, so the power generation is limited. The eas...
