Problems solved by technology
During the use of wind turbine bearings, due to the dust in the air, these dusts will adhere to the bearings when they enter the wind turbine, which will affect the use of the bearings. At the same time, in order to facilitate the use of the bearings, it is often necessary to regularly add Lubricating oil, the existing bearing cap structure needs to completely remove the bearing cap for refueling, and the refueling operation is complicated

The invention discloses a bearing inner and outer cover for a wind power generator, and relates to the technical field of wind power generator accessories. The present invention includes an inner cover and an outer cover that cooperate with each other. The inner cover includes an inner cover with a cylindrical structure. The bottom side of the inner cover is provided with a shaft hole for passing the shaft. shaped damping energy-absorbing ring; the opening side of the inner cover is provided with a mounting flange 1, and a number of grooves 1, 2 and 3 are arranged on the mounting flange 1; groove 1, groove 2 and groove 3 The third groove is a fan-shaped structure; the outer cover includes a cylindrical outer cover body, the inner bottom side of the outer cover body is provided with a number of damping energy-absorbing blocks, and the opening side of the outer cover body is provided with a matching flange. The flange 2 is installed; the flange 2 is installed with a plurality of protrusions that can cooperate with the groove 1, the groove 2 and the groove 3, and the protrusion is a fan-shaped structure. In the present invention, the inner and outer covers of the bearing composed of the inner cover and the outer cover matched with each other realize the protection of the bearing.
Description
technical field [0001] The invention belongs to the technical field of wind power generator accessories, in particular to an inner and outer bearing cover for a wind power generator. Background technique [0002] Wind turbine is a kind of electrical equipment that converts wind energy into mechanical energy and then into electrical energy. It is widely used in areas with considerable wind power, such as Finland, Denmark, and some western parts of my country. The principle of wind power generation is to use the wind to drive the blades of the windmill to rotate, and then increase the speed of rotation through the speed increaser to drive the generator to generate electricity. Since wind energy is a renewable and non-polluting energy source, it has been paid more and more attention and vigorously developed; bearings are an indispensable component in motor wind turbines, and bearings require bearing inner and outer covers. During the use of wind turbine bearings, due to the du...
