A braking device for wind turbines

Abstract

The invention discloses a braking device for a wind driven generator, and relates to the technical field of wind driven generators. The braking device comprises a cabin body, wherein a low-speed shaftpenetrates through one side of the cabin body; an impeller is arranged at one end of the low-speed shaft, and the impeller is arranged outside the cabin body; a transmission is arranged at the otherend of the low-speed shaft; a fixed block is arranged at the bottom of the transmission, and the bottom of the fixed block is fixedly connected with the bottom of an inner cavity of the cabin body; ahigh-speed shaft is arranged on one side of the transmission, and a generator is arranged at one end of the high-speed shaft; the low-speed shaft and the high-speed shaft are both sleeved with a brakedisc; and a motor is arranged on one side of the bottom of the inner cavity of the cabin body, and a rotating shaft is arranged at one end of an output shaft of the motor. According to the brake device for the wind power generator, brake pads can be conveniently arranged on placing discs, the brake pads are convenient to assemble and disassemble, the braking effect of the wind driven generator isimproved, the service lives of the high-speed shaft and the low-speed shaft are prolonged, the maintenance and replacement frequency of the high-speed shaft and the low-speed shaft is reduced, and the working efficiency of the wind driven generator is indirectly improved.

Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a braking device for wind power generators. Background technique [0002] A wind turbine is a power machine that converts wind energy into mechanical work, also known as a windmill. Broadly speaking, a wind turbine is a thermal energy utilization engine that uses the sun as a heat source and the atmosphere as a working medium. Wind power uses natural energy. Compared with diesel power generation, it is much better, but if it is used in an emergency, it is still not as good as diesel generators. Wind power generation cannot be regarded as a backup power source, but it can be used for a long time. [0003] Traditional wind turbines are equipped with braking devices on high-speed shafts. When used for too long, the high-speed shafts and low-speed shafts will be unevenly loaded and easily damaged, which increases the frequency of maintenance and replacement of high-spee...
