Bearing with dust-proof and heat dissipation functions

Abstract

The invention relates to a bearing with dust-proof and heat dissipation functions. The bearing comprises an inner ring, an outer ring, balls and a plastic dust-proof cover, the balls are arranged between the inner ring and the outer ring, and a plurality of heat dissipation holes are formed in the inner ring and the outer ring; heat conduction layers are arranged on the inner walls of the heat dissipation holes, and heat dissipation layers are arranged on the inner walls of the heat conduction layers; a cooling pipe is arranged on one side of the balls, and a coolant is filled in the inner cavity of the cooling pipe; two convex rings are arranged on the outer wall of the outer ring, a bearing hole is formed in the center of the plastic dust-proof cover, through holes are formed in the positions, corresponding to the heat dissipation holes, of the plastic dust-proof cover, and the inner diameters of the through holes are the same as the inner diameters of the heat dissipation holes; anda round clamping plate is arranged on one side of the plastic dust-proof cover, a circle of clamping groove is formed in the inner wall of the round clamping plate, and the clamping groove is connected with the convex rings in a nesting mode. The bearing has good dust-proof and heat dissipation effects.

Description

technical field [0001] The invention relates to a bearing with dust-proof and heat-dissipating functions, belonging to the technical field of bearings. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and maintain the center of the shaft. As a fixed part, bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load during the transmission process of the equipment. At present, the bearings on the market are generally It consists of an inner ring, an outer ring, and balls or rollers placed in the middle.

[0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and maintain the center of the shaft. As a fixed part, bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load during the transmission process of the equipment. At present, the bearings on the market are generally It consists of an inner ring, an outer ring, and balls or rollers placed in the middle. Some bearings will have a bearing cage between the balls or rollers. It partially wraps all or part of the rolling elements and moves with them. Because the bearing During work, due to the friction between the rolling elements and the bearing cage, a large amount of heat will be generated, especially when some mechanical equipment rotates at a relatively fast speed, the generated heat will be even greater, which will cause the bearing to heat up and get stuck The failure of the bearing makes the bearing unable to work normally. Therefore, the machine tool spindle and its related components are required to meet the needs of high-speed machining, which puts forward new requirements for the performance of the bearing, and dust and impurities enter the inside of the bearing, which will lead to a reduction in the service life of the bearing. , therefore, further improvement is required
