[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. During operation, the inner ring of the bearing needs to rotate at high speed along with the shaft. The friction coefficient is reduced between the inner and outer rings by means of ball bearings and the built-in grease. Friction is an objective existence, and the friction between the ball bearings or the rotating needles in the bearings and the inner and outer rings of the upper and lower layers will continuously accumulate heat.

[0003] However, although the friction coefficient between the inner ring and the outer ring is reduced by the ball body and the grease inside, it is still impossible to avoid the bearing from heating up during operation, causing the bearing to be damaged due to high temperature during operation.

[0029] Furthermore, the inner side of the outer ring 101 in the outer shell 1 is movably connected to the inner ring 201 in the middle shell 2 by a rolling ball 106. The inner ring 201 is hollow inside to form a heat dissipation channel 202. A bump 203 protrudes inside the heat dissipation channel 202. The hollow heat dissipation channel 202 inside the inner ring 201 is used to inject cooling air, and the bump 203 protruding inside the heat dissipation channel 202 is used to support the bearing.
