Description

Technical Field

[0001] The utility model relates to a bearing outer ring structure with a rubber ring, belonging to the technical field of bearings. Background Art

[0002] The outer ring of the roller bearing adopts a full complement cylindrical roller bearing with a thick outer ring wall. The outer diameter surface of the roller has cylindrical or curved shapes, which can be designed to match the raceway surface according to the application. With this outer ring, the roller can roll directly on the raceway and can withstand heavy loads and impact loads.

[0003] The outer ring of the bearing is an important component of the bearing. The existing technology, such as a one-way outer ring bearing disclosed in patent number CN202220551485.3, belongs to the field of mechanical parts technology. The key points of its technical solution include the outer ring of the bearing. When the bearing is working normally, when the outer ring of the bearing rotates, its inner side will contact the mating steel ball. During normal use and when vibration occurs, the mating steel ball moves toward the inside of the mating block due to vibration. Because the inner side of the mating block is conical, when the mating steel ball enters, the lubricating oil inside the hollow shell will flow out from the gap between the mating block and the mating steel ball. The lubricating oil flows out to complete the lubrication of the structure.

[0004] The disadvantage of the above-disclosed bearing outer ring is that, when in use, it is necessary to consider the wear resistance and the sound insulation effect, but the disclosed bearing outer ring lacks the above-mentioned properties. Utility Model Content

[0009] In the above-mentioned bearing outer ring structure with an apron, the thickness of the dense corundum contact surface, the thickness of the first silicon oxide surface layer and the thickness of the second silicon oxide surface layer are equal.

[0010] In the above-mentioned bearing outer ring structure with a rubber ring, the ring width of the outer protective rubber ring is twice the thickness of the bearing outer ring body.

[0011] In the above-mentioned bearing outer ring structure with an apron, the sum of the thickness of the graphite bushing layer and the thickness of the nitrile rubber layer is equal to the thickness of the nitrided composite ceramic layer.
