Zirconia ceramic bearing ball

Abstract

The invention discloses a zirconia ceramic bearing ball. The zirconia ceramic bearing ball comprises a jacket and a rotating shaft. The jacket is internally and movably connected with the rotating shaft. A connecting piece is movably connected between the jacket and the rotating shaft. The connecting piece is internally and fixedly provided with a limiting hole. The limiting hole is internally andmovably connected with a bearing ball body. The periphery of the bearing ball body is rotationally connected with a limiting plate. The inner side wall of the jacket is fixedly provided with a firstrolling groove. The top of the rotating shaft is fixedly provided with a second rolling groove. The first rolling groove and the second rolling groove are internally and fixedly connected with graphite rings. The zirconia ceramic bearing ball is novel in design, simple in structure and not prone to being damaged and achieves relatively-high performance of high temperature resistance, a low thermalexpansion coefficient, corrosion resistance and the like, and therefore the service life of the bearing ball can be greatly prolonged, a good automatic lubricating effect is achieved, the working efficiency of the bearing ball is further improved, and the bearing ball is not prone to being damaged and is convenient to use for a long time.

Description

technical field [0001] The invention relates to a bearing ball, in particular to a zirconia ceramic bearing ball. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearings are generally outer rings, inner rings, bearing balls and connecting components are composed. [0003] The current bearing balls usually use steel balls. Due to the high density of steel balls, the centrifugal force is large during high-speed operation, resulting in high rolling loads, making the bearings more vulnerable to damage, and under high-speed rotation, the steel balls are more prone to damage. The higher temperature makes it easier to cause cracks in the bearing, which greatly reduces the service life of the bearing ball, which can no longer meet people's needs. To this end, we propose a zirconia cera...
