Novel ultrathin-wall high-abrasion-resisting ceramic bearing

Abstract

The invention discloses a novel ultrathin-wall high-abrasion-resisting ceramic bearing. The novel ultrathin-wall high-abrasion-resisting ceramic bearing comprises a bearing outer ring and a bearing inner ring. A ball groove is formed in the inner side wall of the bearing outer ring, balls are arranged in the ball groove, the multiple balls are arranged, and the bearing inner ring is arranged at one end of each ball. A plurality of ball fixing grooves are formed in the surface of the bearing inner ring, and lubricating oil suction grooves are formed between the ball fixing grooves. An abrasionresisting layer is arranged on the inner side of the bearing inner ring, and dustproof sound isolation rings are arranged on the two sides of the part between the bearing outer ring and the bearing inner ring. The novel ultrathin-wall high-abrasion-resisting ceramic bearing is simple in structure, friction is effectively reduced, the heat dissipation efficiency is greatly improved, and very good practicability is achieved; and the novel ultrathin-wall high-abrasion-resisting ceramic bearing can stably work under the environment that temperature changes are sharp, hardness is high, and abrasionresistance is achieved.

Description

technical field [0001] The invention relates to the technical field of ceramic products, in particular to a novel ultra-thin-walled and highly wear-resistant ceramic bearing. Background technique [0002] Most of the existing bearings use steel bearings. Due to the relatively high density of steel, the bearing weight is relatively large, and the centrifugal force on the outer ring during rotation is relatively large, which reduces the service life of the bearings; at the same time, the steel bearings expand and contract when heated. The impact is relatively large, so steel bearings cannot work in environments with severe temperature differences. At present, during the long-term operation of the ceramic bearing, due to the high friction between the shaft center and the bushing, it is easy to cause the inner ring to burst and get stuck, resulting in undesirable losses. To this end, we propose a new type of ultra-thin wall and high wear-resistant ceramic bearing. Contents of...

[0002] Most of the existing bearings use steel bearings. Due to the relatively high density of steel, the bearing weight is relatively large, and the centrifugal force on the outer ring during rotation is relatively large, which reduces the service life of the bearings; at the same time, the steel bearings expand and contract when heated. The impact is relatively large, so steel bearings cannot work in environments with severe temperature differences

At present, during the long-term operation of the transmission drive of ceramic bearings, due to the large friction between the shaft center and the bushing, it is easy to cause the inner ring to burst and get stuck, resulting in bad wear and tear.
