Abstract
The invention discloses a mechanical brake device of a wind driven generator, which comprises a shaft sleeve that is sheathed and connected with a main shaft; the shaft sleeve is externally provided with a brake disc which is externally provided with a brake; a spiral spring is positioned between the shaft sleeve and the brake disc; and one end of the spiral spring is fixedly connected with the shaft sleeve, and the other end thereof is fixedly connected with the brake disc. The mechanical brake device of the wind driven generator leads the brake and the brake disc to have less abrasion when in braking, is less in heat emission and low in cost, and has long service life.
Description
Technical field
The present invention relates to braking device, be specifically related to a kind of mechanical braking device of wind-driven generator.
Background technique
Braking device is used for the braking of machinery and electromechanics etc., the braking device of wind-driven generator is used for the braking of blower fan, the braking device of wind-driven generator is mainly mechanical braking, mechanical braking is to be finished by mechanical braking device, the structure of present mechanical braking device comprises the axle sleeve with the main shaft socket, the axle sleeve brake disc that has been rigidly connected outward, brake disc is provided with brake outward, when needing braking like this, allow brake and brake disc pressing friction, form reaction force, reach the braking purpose main shaft and axle sleeve, because the energy of braking is frictionally entirely, so in order to reach the braking purpose, the frictional force of brake and brake disc needs very big, this causes the braking device heating big, the noise height, the wearing and tearing of brake and brake disc are also more during each braking, thereby the braking device working efficiency descends comparatively fast, and braking device is shorter working life, need just can reach and brake purpose preferably through the high aerial frequent braking device of changing of being everlasting.
Summary of the invention
The wearing and tearing of brake and brake disc were less when technical problem to be solved by this invention provided a kind of the braking, and the braking device heating is few, and noise is low, and working life is the mechanical braking device of long wind-driven generator.
The present invention solves the problems of the technologies described above the technological scheme that is adopted: a kind of mechanical braking device of wind-driven generator, comprise axle sleeve with the main shaft socket, described axle sleeve is provided with brake disc outward, described brake disc is provided with brake outward, be provided with helical spring between described axle sleeve and the described brake disc, a described helical spring end is fixedlyed connected with described axle sleeve, and the described helical spring the other end is fixedlyed connected with described brake disc.Helical spring and axle sleeve and brake disc Placement can be that welding is fixing, also can be to rabbet, connect and fix etc., get final product so long as helical spring can not be shifted.
Compared with prior art, the invention has the advantages that a kind of mechanical braking device of wind-driven generator, comprise axle sleeve with the main shaft socket, axle sleeve is provided with brake disc outward, brake disc is provided with brake outward, be provided with helical spring between axle sleeve and the brake disc, a helical spring end is fixedlyed connected with axle sleeve, and the helical spring the other end is fixedlyed connected with brake disc.Like this when braking, brake and brake disc pressing friction form the reaction force to main shaft and axle sleeve, this reaction force tightens the helical spring between brake disc and the axle sleeve immediately, the helical spring that tightens produces bigger reaction force to main shaft and axle sleeve, reach very fast braking, braking effect is better, this makes and the frictional force of brake and brake disc is just relative less, the braking device heating is also less, noise is lower, and just wearing and tearing are just less for brake and brake disc when braking at every turn, thereby the braking device working efficiency improves, prolong the working life of braking device, and the high aerial braking device frequency of changing reduces.Therefore the wearing and tearing of brake and brake disc were less when the present invention was a kind of the braking, and the braking device heating is few, and noise is low, and working life is the mechanical braking device of long wind-driven generator.
