Mechanical transmission system for extra-large vertical axis wind power generation device

Abstract

The invention discloses a mechanical transmission system for an extra-large vertical axis wind power generation device. The system comprises a vertical axis, a central gear fixed on the vertical axis, a generator and a base. The key point is that: the generator has a vertical structure; the axis of a motor is vertical to the base; the base at the bottom end of the vertical axis is provided with aload-bearing bearing group; the vertical axis is fixed by the load-bearing bearing group and a support bearing; a plurality of satellite gears connected with a rotating shaft of the generator are arranged at the periphery of the central gear; the central gear is provided with a brake disc and an electric control brake; and the rotating shaft of the generator is connected with an electric control clutch. The system has a novel structure, a reasonable design and reliable performance, is safe and stable in operation, can be stably started at a low wind speed, can keep a rated rotating speed evenif the wind speed is high, effectively solves the problem of mechanical transmission in large vertical axis wind power generation, and has the generated power of over 1.2MW.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a mechanical transmission system for transmitting the rotational torque generated by a vertical axis to multiple generators due to wind force. Background technique [0002] One of the great features of the extra-large vertical axis wind power generation device is the length of the vertical axis and its own weight, making it difficult to install and transmit torque. Coupled with the instability of wind speed, it brings many problems to the start-up and control of the power generation device. In particular, to make full use of wind energy and realize high-power power generation, it is necessary to stably drive multiple generators to run simultaneously. Due to the uncertainty of the wind force, the matching generator is either in a standby start state because the wind force cannot reach the working torque of the generator; or the wind force has reached the working tor...

AI Technical Summary

Problems solved by technology

Due to the uncertainty of the wind force, the matching generator is either in a standby start state because the wind force cannot reach the working torque of the generator; or the wind force has reached the working torque of a single generator, but cannot reach multiple generators Generator starting torque, still can not start power generation smoothly

As a result, it is difficult to fully utilize the wind energy of the power generation system, the power generation efficiency is greatly reduced, and the equipment can only maintain low-level operation
