Background

The bearing is an important and key basic part in the equipment manufacturing industry, directly determines the performance, quality and reliability of important equipment and host products, and is known as a heart part for equipment manufacturing. Through years of development, although the bearing industry in China has formed a considerable scale and is located in the third place of the world, most of the bearing industry is concentrated at the low end, and in the field of high-end bearing manufacturing, a considerable gap still exists compared with developed countries. The deep groove ball bearing is suitable for operation at high rotating speed or even extremely high rotating speed, is very durable and does not need frequent maintenance. The deep groove ball bearing mainly bears radial load and can bear the radial load and the axial load at the same time. When it is subjected to only radial loads, the contact angle is zero.

The deep groove ball bearing is widely used in the equipment manufacturing industry, so the service life and the effect of the deep groove ball bearing are very worth paying attention to, the deep groove ball bearing is suddenly not lubricated enough due to increased friction in the working process, mechanical rotation is influenced, lubricating oil needs to be added into the deep groove ball bearing for lubrication, and the deep groove ball bearing cannot dissipate heat due to the fact that the whole space is closed when in operation. In the use, the condition that need change not unidimensional ball can appear, and current deep groove ball bearing can't adapt to the diameter size of different balls well.

Preferably, one section of the spring arranged in the sealing ring is provided with a fixed block, and the fixed block is fixedly connected with the spring.

Preferably, one sections of the two soft blocks, which are close to the balls, are provided with press strips, and the press strips are fixedly connected with the soft blocks and made of heat-resistant rubber.

Preferably, a plurality of air holes are uniformly formed in the outer ring of the deep groove ball bearing.

Preferably, the height and the thickness of the outer ring of the deep groove ball bearing and the inner ring of the deep groove ball bearing are the same, and the diameter of the outer ring of the deep groove ball bearing is larger than that of the inner ring of the deep groove ball bearing.

Preferably, the balls are made of steel, and the surfaces of the balls are polished.

The utility model has the advantages that:

make lubricating oil effective reasonable protect the ball through setting up sealing washer and bearing oil guide pipe, reduce the loss that frictional force brought, can adapt to adjustment ball diameter at will through setting up the spring, make things convenient for the ball to change, the bleeder vent that sets up makes deep groove ball bearing can give off partly heat when the operation.
