A high-precision bearing and its manufacturing method

Abstract

The invention relates to the technical field of machinery and provides a high precision bearing and a process method thereof. The high precision bearing comprises an inner ring part and an outer ringpart as well as a ring seat arranged between the inner ring part and the outer ring part; the ring seat is matched with a ring cover and a plurality of ball pieces and a lubricating structure are arranged; the inner ring part is arranged on the inner side of the outer ring part and is provided with an outer ring slot; the outer ring part is provided with an inner ring slot relative to the outer ring slot; sunken portions meeting the quantity of the plurality of ball parts are distributed on the ring seat annularly in an equally spaced manner; bottom planes and arc-shaped walls, corresponding to two sides, vertically connected to the bottom planes, are formed in the sunken portions; and the ball parts are clamped by the arc-shaped walls on two sides in the sunken portions, and lean againstthe inner and outer ring slots. Therefore, the structure solves the technical problem of a bearing provided with the lubricating structure, and achieves the effects of enhancing the product property and prolonging the service life of the product.

Description

technical field [0001] The invention provides a bearing, especially a high-precision bearing and a process method thereof. Background technique [0002] Bearings are an important part of the combination of rotation in machinery, and their main function is to support, guide and limit the movement of the rotating shaft. At the same time, the bearing also has the function of reducing friction loss and increasing transmission efficiency. However, the structure of the bearing generally includes an inner ring, an outer ring, a rotating body, a cage, and a plurality of rolling elements (such as balls) arranged between the inner ring and the outer ring. Do the rolling motion at intervals. The inner and outer rings have corresponding track grooves, and the rolling elements form geometric point contact in the track grooves of the inner and outer rings, theoretically rolling motion and / or revolution in the track grooves of the inner ring and the outer ring . [0003] Usually, a bal...

AI Technical Summary

Problems solved by technology

[0003] Generally, ball bearings with rolling elements (such as balls) may affect the service life of the bearing and the parts related to the bearing due to changes in vibration, wear, temperature, pressure, etc., which will increase the use cost of the product
