Problems solved by technology
[0003] In the plastic-coated bearings of the prior art, due to the friction between the plastic-coated layer and the belt, frictional heat will be generated during operation, which will soften the plastic-coated layer and cause relative sliding between the plastic-coated layer and the outer ring of the bearing. There will be relative rotation between them, which will affect the service life of the bearing

Embodiment Construction
[0013] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:
[0014] like figure 1 As shown, the present invention mainly includes a bearing outer ring 1 , a bearing inner ring 2 , steel balls 3 , a cage 4 and a sealing ring 5 .
[0015] The bearing inner ring 2 is concentrically arranged in the bearing outer ring 1, and a plurality of cages 4 for positioning each steel ball 3 are arranged between the bearing inner ring 2 and the bearing outer ring 1, and each cage 4 is provided with a plurality of The ball installation chambers are evenly distributed along the circumferential direction, and a steel ball 3 is rollingly installed in each ball installation chamber.
[0016] Both sides of the cage 4 are provided with seal rings 5 respectively, and the inner and outer rings of the seal ring 5 are respectively in interference fit with the bearing inner ring 2 and the bearing outer ring 1, so that the seal ring 5 is...

The invention belongs to the technical field of bearings and relates to a bearing, in particular to an outer ring knurled bearing. The outer ring knurled bearing comprises a bearing outer ring, a bearing inner ring, steel balls, cages and sealing rings; one or more ring grooves distributed in the circumferential direction are formed in the outer circumference surface of the bearing outer ring; andknurls are arranged in the centers of the ring grooves. The outer ring knurled bearing is simple, compact and reasonable in structure, the grooves extending in the circumferential direction are formed in the outer surface of the bearing outer ring, the straight-pattern knurls are machined in the grooves, thus the binding force of plastic and the bearing is increased, the quality of the plastic-coated bearing is improved, and the service life of the bearing is prolonged.
Description
technical field [0001] The invention relates to a bearing, in particular to an outer ring knurled bearing, which belongs to the technical field of bearings. Background technique [0002] Plastic-coated bearings generally refer to wrapping a layer of plastic on the outside of the bearing, and the plastic materials are generally nylon, polyoxymethylene and engineering plastic polypropylene. Outsourcing plastic has certain hardness, impact resistance, friction resistance and certain self-lubricating property. Plastic-coated bearings are a newly emerging industry in China. They are widely used in mechanical equipment, industrial assembly lines, furniture and hardware accessories. [0003] In the plastic-coated bearings of the prior art, due to the friction between the plastic-coated layer and the belt, frictional heat will be generated during operation, which will soften the plastic-coated layer and cause relative sliding between the plastic-coated layer and the outer ring of t...
