Description

Technical Field

[0001] The utility model relates to the technical field of bearings, and more specifically, to a bearing with a noise reduction function. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during movement, and ensure their rotation accuracy. They are widely used in various fields. When the inner and outer rings of the bearings are working, they drive the balls to rotate at high speed. Long-term friction of the balls can easily cause noise. Generally, when the bearings produce noise, they are usually replaced directly or disassembled and lubricated.

[0003] The utility model patent with patent publication number CN210978196U discloses a bearing with noise reduction function. Through the outer ring of the bearing, the inner ring of the bearing, the ball, the plugging plate, the annular groove, the first aluminum plate, the first silencer hole, the first silencer plate, the second silencer plate, the second aluminum plate, the second silencer hole and the silencer cotton, when the bearing body generates noise during operation, the generated noise is transmitted to the corresponding second silencer hole, and the silencer cotton reduces the noise in the second silencer hole, and at the same time, the reduced noise is transmitted to the corresponding first silencer plate, and the first silencer plate reduces the reduced noise. The noise on the first sound-absorbing plate is reflected to the corresponding second sound-absorbing plate, and the other part of the noise is reflected to the point where the noise occurs. The noise on the second sound-absorbing plate is reflected to the corresponding first sound-absorbing plate. The reflection of multiple first sound-absorbing plates and multiple second sound-absorbing plates is used to make the first sound wave that originally propagated forward return to the origin and turn back to propagate forward again. The two sound waves converge, thereby interfering with each other and canceling each other out. After multiple reflections, the noise is gradually reduced, and the reduced noise is silenced again through the corresponding first sound-absorbing hole, thereby achieving a good sound-absorbing effect.

[0004] However, in actual use, although the noise generated by the bearing itself can be reduced, the wear of the ball cannot be processed, and it is not convenient to add lubricating oil. The abnormal noise generated by the wear of the ball is not easy to hear due to the noise reduction, so that the ball is always in a worn state, which causes the bearing to be directly scrapped, and it is not convenient to add lubricating oil, so it needs to be replaced, which reduces the service life of the bearing. Therefore, a bearing with noise reduction function is proposed. Utility Model Content
