Problems solved by technology
[0002] Ordinary bearings have relatively high rigidity in each part. When subjected to an unstable load during operation, the vibration amplitude of the bearing will increase, and the noise will increase at the same time, and the transmission system will run unevenly.
It will not only reduce the service life of the bearing, but also affect the life and precision of other parts in the transmission system

Embodiment Construction
[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] Such as Figure 1-3 As shown, the three-point contact radial ball bearing includes: outer ring assembly, rolling element 1, and inner ring 2; rolling element 1 is set between the outer ring assembly and inner ring 2, the inner diameter of the outer ring assembly and the inner ring The outer diameters are respectively provided with raceways that match the rolling elements 1, and the rolling elements 1 are rollingly connected between the outer ring assembly and the inner ring 2; the outer ring assembly is a combined overall structure, which consists of : one-piece outer sleeve 3, two-piece tolerance ring 4, two-piece outer ring 5;
[0020] The two-piece outer ring 5 and the two-piece tolerance ring 4 are separately arranged with the rolling body 1 as the center and close to the two end faces of the bearing ring;
[0021] The outer ring 5 and the tolerance ring...

The invention relates to an oil-lubricated bearing, in particular to a three-point contact radial ball bearing, and belongs to the technical field of bearings. The three-point contact radial ball bearing comprises an outer ring assembly, a rolling body and an inner ring; the rolling body is arranged between the outer ring assembly and the inner ring; raceways matched with the rolling body are arranged on the inner diameter of the outer ring assembly and the outer diameter of the inner ring; the rolling body is connected between the outer ring assembly and the inner ring in a rolling manner; the outer ring assembly is of a combined overall structure and sequentially comprises an integrated outer sleeve, a two-body type tolerance ring and a two-body type outer ring from outside to inside. According to the oil-lubricated three-point contact radial ball bearing, the thickness of the outer ring is reduced, and the tolerance ring made of rubber is additionally arranged between the outer sleeve and the outer ring, so that not only can normal use of the bearing be met, but also a certain effect can be achieved in the aspects of load buffering and noise reduction, the sealing performance of the bearing is improved, the damage to the bearing is reduced, and the use reliability of the bearing is improved.

technical field [0001] The invention relates to an oil-lubricated bearing, in particular to a three-point contact radial ball bearing, and belongs to the technical field of bearings. Background technique [0002] Ordinary bearings have relatively high rigidity in each part. When subjected to an unstable load during operation, the vibration amplitude of the bearing will increase, and at the same time the noise will increase, and the transmission system will run unevenly. It will not only reduce the service life of the bearing, but also affect the life and precision of other parts in the transmission system. Contents of the invention [0003] In view of the above-mentioned technical defects, the object of the present invention is to provide a three-point contact radial ball bearing, which can compensate the tolerance of the bearing to a certain extent by setting a tolerance ring, and has a certain improvement in vibration and noise; improves the sealing of the bearing Perfo...
