A wind turbine main shaft with buffer function

Abstract

The invention relates to the technical field of generator main shafts, and discloses a wind power generator main shaft with a buffer function, including a first bearing seat, a second bearing seat, a first main shaft, a second main shaft, a meshing wheel and a claw wheel. The main shaft is rotatably installed inside the first bearing seat through the first rolling bearing, the second main shaft is rotatably installed inside the second bearing seat through the second rolling bearing, the meshing wheel is fixedly arranged at the right end of the first main shaft, and the claw wheel is fixedly arranged at the second At the left end of the main shaft, the meshing wheel and the pawl wheel cooperate. The interior of the meshing wheel and the outside of the meshing groove are surrounded by a plurality of evenly distributed cavities, and the interior of the multiple cavities is provided with a buffer mechanism for the pawl wheel. The main shaft of the wind power generator with the buffer function can have a good buffer effect on the claw wheel, greatly reduces the wear of the main shaft of the wind power generator, and is convenient for staff to disassemble and assemble the connecting rod and the ball, with low labor intensity.

Description

Technical field [0001] The present invention relates to the field of generator spindle technology, and is specifically a wind turbine spindle having a buffer function. Background technique [0002] With the continuous development of wind power, the amount of airborne charger has also been greatly improved. However, the high failure rate of the wind turbine hinders the development of wind power. Based on the problem of failure diagnosis of wind power, it is learned that a large part of the failure of wind turbines is caused by the impact caused by the airway to the gearbox and motor. Since the wind speed is uncontrollable, the impact caused by wind speed is inevitable. However, the failure rate of the device can be reduced by increasing the buffer device to reduce the impact of the device during the power transmission process, thereby reducing the failure rate of the device. The spindle is at the front end of the wind power plant, and if the buffer spindle can be designed, it can ...

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a wind turbine main shaft with a buffer function, which has a good buffering effect on the claw wheel, greatly reduces the wear of the wind power generator main shaft, and is convenient for the staff to connect the connecting rod and the ball Disassembly and assembly, low labor intensity, etc., solve the problem that the buffer structure of the main shaft of the wind turbine mainly uses the vertical elastic force to buffer the claw wheel, and the buffer effect is poor, and the above buffer structure is in contact with the claw wheel It is inconvenient to disassemble the parts, which increases the labor intensity of the staff
