Problems solved by technology

[0003] The self-aligning bearings currently used all need to be equipped with springback pressing devices, such as stamping springs or coil springs. It is difficult to assemble during use, and there are many parts, which is easy to produce fit gaps and loosen after long-term use.

Embodiment Construction

[0027] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0028] Such as Figure 1-Figure 4 As shown, the present invention includes the following characteristic components: 1 is a bearing race, 2 is an inner circlip, 3 is a dust cover, 4 is an inner ring of a bearing, 5 is an outer ring of a bearing, 6 is a rubber washer, and 7 is a cage. 8 is a steel ball group, and 9 is grease.

[0029] A rolling bearing assembly of the present invention includes a bearing body, which includes a steel ball group composed of a plurality of steel balls and a cage, the steel ball group is embedded in the cage to form a whole, and the bearing body is installed on the inner ring of the bearing and the outer ring of the bearing In the...

Abstract

The invention relates to a rolling bearing assembly which comprises a bearing body, a steel ball group formed by multiple steel balls, and a holder. The steel ball group is embedded into the holder soas to form a whole; the bearing body is arranged in a cavity space formed by channels of a bearing inner ring and a bearing outer ring; two contact points are produced on contact surfaces between each steel ball in the steel ball group and the bearing inner ring as well as each steel ball and the bearing outer ring; and the bearing body, the bearing inner ring and the bearing outer ring are arranged in a bearing seat ring. According to the bearing assembly, the bearing can have a larger center adjusting quantity under the condition of a small free clearance, and meanwhile, the bearing assembly can further provide a certain resilience force and damping, so that the clearance of an assembly system is fully eliminated, and the vibration is reduced.

Description

technical field [0001] The invention relates to a rolling bearing assembly, which belongs to the technical field of bearings. Background technique [0002] The self-aligning function of the ball bearing is very limited during operation. If an outer spherical self-aligning bearing is used, it will be difficult for the outer self-aligning surface to provide resilience, and it can only rotate in a deflected position. In some occasions, such as the support bearing of the worm, it is necessary to provide a certain amount of self-alignment while allowing a certain rebound preload between the worm and the turbine, so as to avoid the shock vibration caused by the free gap. [0003] The self-aligning bearings currently used all need to be equipped with springback pressing devices, such as stamping springs or coil springs, which are difficult to assemble during use and have many parts, which are prone to fit gaps and loosening after long-term use. Contents of the invention [0004]...
