A heat-dissipating bearing

Abstract

The invention discloses a bearing capable of dissipating heat, relating to the field of produced parts of industrial machinery. The bearing comprises bearing outer rings and bearing inner rings, wherein rolling bodies are arranged between the bearing inner rings and the corresponding bearing outer rings; one side, close to the rolling bodies, of each bearing outer ring is of a concave surface shape, one side, close to the rolling bodies, of each bearing inner ring is of a concave surface shape, the concave surfaces of each bearing outer ring and the corresponding bearing inner ring form an arc surface, and each arc surface is connected with the rolling bodies; a fixed frame is arranged among the rolling bodies, sealing rings are arranged between the bearing outer rings and the corresponding bearing inner rings, the thicknesses of the sealing rings are 30mm-100mm, and the sealing rings are used for isolating the rolling bodies from the outside; compression plates are arranged outside the sealing rings, and heat-dissipation oil layers are arranged between the compression plates and the sealing rings. The bearing capable of dissipating the heat is simple in structure, reliable in rotation performance, low in rotation noise, good in heat-dissipation performance, wide in application rang and low in cost and can work in a high-speed running environment.

Description

technical field [0001] The invention relates to a bearing capable of dissipating heat, which relates to the field of production parts of industrial machinery. Background technique [0002] The world is developing and society is progressing. Since the Industrial Revolution, mechanical production has been full of people's social production activities. From large-scale machinery to daily-use screws, they have greatly developed social productivity and brought benefits to people's lives. Mechanical production and application , the bearing plays an irreplaceable role in the transmission process of various parts of the machine. Although the bearing is widely used, its improvement work has always attracted people's attention. The traditional bearing outer ring and the bearing inner ring are directly provided with rolling elements. Without any protective device outside, it is easy to rust and wear after long-term use, which greatly shortens the service life of the bearing, and the ro...

[0002] The world is developing and society is progressing. Since the Industrial Revolution, mechanical production has been full of people's social production activities. From large-scale machinery to daily-use screws, they have greatly developed social productivity and brought benefits to people's lives. Mechanical production and application , the bearing plays an irreplaceable role in the transmission process of various parts of the machine. Although the bearing is widely used, its improvement work has always attracted people's attention. The traditional bearing outer ring and the bearing inner ring are directly provided with rolling elements. Without any protective device outside, it is easy to rust and wear after long-term use, which greatly shortens the service life of the bearing, and the rolling body of the bearing has no corresponding track, which also causes great wear to the ball. The application number is The heat-dissipating bearing described in 201210208433.7, although there is a shaft hole on the outer ring of the bearing, can inject lubricating oil into the rolling body to reduce wear between the rolling bodies, but the bearing will generate heat during high-speed rotation. Without a good heat dissipation device, the bearing will be deformed after long-term operation, and noise will be generated during operation, which will destroy the original working environment, so now people pay more attention to the heat dissipation performance of the bearing
