Background

The bearing is a common assembly part on the motor rotating shaft, and mainly has the effects of reducing mechanical friction, bearing radial load and axial load and ensuring the stable operation of the motor.

The bearing is easy to receive dust in the equipment during working, so that the inner roller and the inner ring of the bearing are infected with dust, and in the process of rotary friction, the inner ring and the roller of the bearing are worn by impurities, so that the working efficiency of the equipment is reduced, the service life of the bearing is shortened, and the equipment is easy to damage;

in the process of rotating the rotating shaft at high speed, lubricating oil is easy to run off from the bearing, so that dry grinding of the bearing rollers and the bearing occurs, and the working efficiency of the rotor is affected.

A mating angular ball bearing structure as in CN201520408560.0 is comprised of a pair of back-to-back angular ball bearings with a play spacer mounted between them.

The above patents have an optimizable space: the sealing structure can be added to the bearing, so that the loss of lubricating oil at high temperature is reduced, and impurities such as dust are prevented from entering the bearing.

The aim of the utility model can be achieved by the following technical scheme: the utility model provides a bearing pairing structure, includes the bearing, the bearing divide into inner circle and outer lane, the roller is installed at both ends about the bearing, the outer lane links as an organic wholely, bearing inner circle mutually independent, be provided with the sealing block between the inner circle, the draw-in groove has been seted up in the bearing outside, install the dust ring in the draw-in groove.

In the above-mentioned mating bearing structure, a convex ring is provided on the seal block.

In the pairing bearing structure, buckles are arranged at two ends of the dustproof ring, and the buckles are divided into buckling holes and buckles.

In the above pairing bearing structure, the button is provided with a conical structure, and the diameter of the large end of the conical structure is larger than the diameter of the button hole.

In the above-mentioned mating bearing structure, the dust ring length is greater than the bearing perimeter, and the seal block inner diameter is greater than the bearing inner diameter.

Compared with the prior art, the utility model has the advantages that: and the sealing structures such as the sealing gasket, the dust ring and the like are additionally arranged on the bearing to block external dust and prevent lubricating oil from losing, so that the service life of the bearing is prolonged.

Detailed Description

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

As shown in fig. 1, a pairing structure of a bearing 1 comprises the bearing 1, wherein the bearing 1 consists of an inner ring 11 and an outer ring 12, rollers 13 are arranged at two ends between the inner ring 11 and the outer ring 12, the outer ring 12 is connected into a whole, the inner rings 11 are mutually independent, a sealing block 2 is arranged between the inner rings 11 and is used for sealing a gap between the inner rings 11 to prevent lubricating oil from flowing out, and meanwhile, the inner rings 11 are connected to ensure that the two inner rings 11 rotate together; the clamping groove 14 is formed in the outer side of the bearing 1, the dustproof ring 3 is arranged in the clamping groove 14 and used for blocking external impurities from entering, and the clamping groove 14 is provided with the dustproof ring 3, so that the difficulty of entering dust is increased due to the bending of the clamping groove 14, and meanwhile oil liquid is prevented from leaking.

As shown in fig. 1, the sealing block 2 is provided with a collar 21. The convex ring 21 improves the contact area between the sealing gasket and the inner ring 11, improves the sealing performance of the sealing block 2, and strengthens the connection between the sealing block 2 and the inner ring 11.

As shown in fig. 1 to 4, the two ends of the dust ring 3 are provided with buckles, the buckles are divided into buckling holes 31 and buckles 32, and the buckling holes 31 and the buckles 32 are beneficial to ensuring that the dust ring 3 cannot fall off in the working process of the bearing 1, so that equipment is damaged.

As shown in fig. 3 and 4, the button 32 is provided with a conical structure 321, the diameter of the large end of the cone is larger than that of the button hole 31, the dust ring 3 is made of a non-metal material with elasticity, such as rubber, and the button hole 31 is connected with the button 32 after being stretched and deformed, and the conical structure 321 limits the movement of the button hole 31 end of the dust ring 3, so as to prevent the dust ring 3 from being accidentally separated from the bearing 1.

As shown in fig. 1 to 3, the dust ring 3 has a length greater than the circumference of the bearing 1, and the sealing block 2 has an inner diameter greater than the inner diameter of the bearing 1. The dust ring 3 is a part which is formed by encircling long strips into a ring shape, and the length of the dust ring is longer than the circumference of the bearing 1, so that the dust-proof capacity of the dust ring 3 is enhanced; the inner diameter of the sealing block 2 is larger than that of the bearing 1, so that the sealing block 2 can be prevented from being in direct contact with the rotating shaft, and the sealing block 2 is prevented from affecting the rotation of the rotating shaft.
