Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-7, an embodiment of the present invention is shown: a bearing without magnetic materials comprises an inner ring 1 and an outer ring 2, wherein a first wear-resistant block 5 is arranged on the outer wall of the inner ring 1, the outer ring 2 is sleeved on the inner ring 1, a first round hole 9 is formed in the outer ring 2, first threads 10 are symmetrically formed in the outer ring 2, a second bearing ring 11 is fixedly connected to the outer wall of the outer ring 2 through the first threads 10, a second round hole 12 is formed in the outer wall of the second bearing ring 11, second threads 13 are formed in the outer ring 2, a third bearing ring 14 is fixedly connected to the outer wall of the outer ring 2 through the second threads 13, and third wear-resistant blocks 15 are distributed on the outer wall of one side of the third bearing ring 14; one end of the inner ring 1 is fixedly connected with an installation flange 3, and a first installation hole 4 is formed in the installation flange 3; a second mounting hole 6 is formed in the inner ring 1; a first bearing ring 7 is sleeved on the inner ring 1, and the first bearing ring 7 is fixedly connected with the mounting flange 3 through a first mounting hole 4; second wear-resistant blocks 8 are distributed on the first bearing ring 7; one end of the outer ring 2 is inserted between the inner ring 1 and the first bearing ring 7; the inner wall of the outer ring 2 is provided with a fourth wear-resistant block 16.

The working principle is as follows: during assembly, firstly, a plurality of first bearing rings 7 are sleeved on an inner ring 1, the first bearing rings 7 and a mounting flange 3 are fixed through a first mounting hole 4, then two second bearing rings 11 are rotationally fixed on an outer ring 2 through a first thread 10, then a third bearing ring 14 is rotationally fixed at one end of the outer ring 2, after the assembly is finished, the assembled outer ring 2 is sleeved on the inner ring 1, one end of the outer ring 2 is inserted into a position between the inner ring 1 and the second bearing rings 11, the assembly work of the whole bearing is finished, and when the bearing is used, first wear-resistant blocks 5, second wear-resistant blocks 8, third wear-resistant blocks 15 and fourth wear-resistant blocks 16 made of CBN are respectively staggered to rub with a smooth surface made of PCBN, so that the friction coefficient of mechanical movement is reduced; when the bearing is partially damaged and needs to be repaired and replaced, a wrench is inserted into the first round hole 9 and the second round hole 12 to assist in disassembly, and the disassembly efficiency is improved.
