Problems solved by technology

Most of the existing bearings are formed by sandwiching a layer of balls between the inner ring and the outer ring. Although this kind of bearing achieves the purpose of realizing rolling motion and reducing friction, because there is only one layer of balls, the number of balls is limited. Therefore, the ability of the bearing to reduce friction is limited, and the bearing capacity of the bearing is small
[0003] At the same time, at present, the bearings produced in the world generally have a short service life. Even if the bearings are processed and produced with high-quality raw materials, the rotation is blocked due to the wear of the balls, which also seriously affects the use efficiency of mechanical equipment.

Embodiment 1

[0043] Such as figure 1 , 2 . Layer 2, the above-mentioned second rolling layer 3 and the above-mentioned third rolling layer 4 are all equipped with cages, and the above-mentioned matching layer 100, the above-mentioned first rolling layer 2, the above-mentioned second rolling layer 3 and the above-mentioned third rolling layer 4 are coaxial with each other , the above-mentioned first rolling layer 2 , the above-mentioned second rolling layer 3 and the above-mentioned third rolling layer 4 are arranged in sequence.

[0044] In this embodiment, it includes a matching layer 100, a first rolling layer 2, a second rolling layer 3 and a third rolling layer 4, and the matching layer 100 can be connected with a shaft; the above-mentioned first rolling layer 2, the above-mentioned second rolling layer 3 and the above-mentioned third rolling layer 4 are all equipped with cages, and the first rolling layer 2, the second rolling layer 3 and the third rolling layer 4 all include commo...

Embodiment 2

[0060] Such as figure 1 , 2 , 3, 4, 5, 6, and 7, this embodiment is based on Embodiment 1, the contact surface between the above-mentioned first intermediate ring 102 and the above-mentioned second rolling element 301 is a slope, and the above-mentioned second intermediate ring 103 and the above-mentioned The contact surface of the second rolling element 301 is an inclined surface.

[0061] In this embodiment, the contact surface between the first intermediate ring 102 and the second rolling element 301 is an inclined surface, and the contact surface between the second intermediate ring 103 and the second rolling element 301 is an inclined surface, so that the second rolling layer 3 It can bear axial force, and the direction of its slope can be opposite to the direction of the slope of the bearing inner ring 101, which ensures that the three-layer bearing can bear axial force in different directions.

[0062] In some implementations of this embodiment, the contact surface b...

Embodiment 3

[0065] Such as figure 1 , 2 , 3, 4, 5, 6, 7, the above-mentioned first rolling layer 2, the above-mentioned second rolling layer 3 and the above-mentioned third rolling layer 4 are axially arranged.

[0066] In the above embodiment, the above-mentioned first rolling layer 2, the above-mentioned second rolling layer 3 and the above-mentioned third rolling layer 4 are axially arranged, and the axial arrangement greatly improves the bearing capacity of the axial force of the three-layer bearing. The scope of application of the three-layer bearing is specified.

Abstract

The invention provides a three-layer bearing, and relates to the technical field of three-layer bearings. A three-layer bearing comprises a matching layer, a first rolling layer, a second rolling layer and a third rolling layer, the first rolling layer, the second rolling layer and the third rolling layer are all provided with retainers, and the matching layer, the first rolling layer, the second rolling layer and the third rolling layer are coaxial with one another. The first rolling layer, the second rolling layer and the third rolling layer are arranged in sequence. The three-layer bearing has the advantages that the structure is simple, the pressure of the rolling body can be shared, the service life and the use safety of the bearing are ensured, meanwhile, the temperature of the bearing is reduced, so that the three-layer bearing can adapt to a high-rotating-speed working environment, the three-layer bearing can still operate normally under extreme conditions, and the reliability and the safety of the bearing are improved.

Description

technical field [0001] The present invention relates to the technical field of three-layer bearings, in particular to a three-layer bearing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Most of the existing bearings are formed by sandwiching a layer of balls between the inner ring and the outer ring. Although this kind of bearing achieves the purpose of realizing rolling motion and reducing friction, because there is only one layer of balls, the number of balls is limited. Therefore, the ability of the bearing to reduce friction is limited, and the bearing capacity of the bearing is small. [0003] At the same time, at present, the bearings produced in the world generally have a short service life. Even if the bearings are processed and produced with high-quality raw materi...
