Ball supply and ball quantity checking device for bearing

Abstract

Provided is a ball supply and ball quantity inspection device for a bearing, which supplies balls to a rolling surface formed on the inner periphery of a bearing outer ring and checks the quantity of the supplied balls. The ball supply and ball quantity inspection device of the present invention comprises: a frame (100), a base (200), a ball supply tool (410), a ball guide (220), a ball quantity inspection device (510), a carriage ( 300) and motion devices. According to the present invention, balls are automatically supplied and distributed to the inside of the outer ring, and at the same time, whether the correct number of balls are supplied is automatically checked, thereby making it very easy to manufacture and inspect the bearing. In particular, there is an effect of improving productivity by reducing working time and labor.

Description

technical field [0001] The present invention relates to a ball supply and ball quantity inspection device for a bearing, and more specifically, to a ball supply and ball supply system for a bearing that automatically supplies and distributes balls to the outer ring of a bearing and automatically checks whether the correct number of balls is supplied. Ball count checking device. Background technique [0002] In general, a bearing is provided on a shaft rotation portion required for shaft rotation. As one example of the bearing, there is a wheel bearing for automobiles. Wheel bearings for automobiles, such as figure 1 Shown is an outer ring 10, two inner rings 20 arranged on the inner periphery 12 of the outer ring 10, two rows of balls 30 arranged between the outer ring 10 and each inner ring 20, and balls for maintaining 30 spaced between ball separators 40 constituted. Here, on the inner periphery 12 of the outer ring 10, a pair of rolling surfaces 14 etc. are formed at...

Problems solved by technology

[0003] On the other hand, in such a wheel bearing, there is a disadvantage that after fitting the balls 30 into the ball separator 40 one by one by hand, the ball separator 40 equipped with the balls 30 must be fitted to the outer ring 10. internal

Therefore, a lot of work time is required and a lot of labor is required, and as a result, there is a problem of lowering productivity and increasing costs.

[0004] In addition, there are also the following disadvantages: in the past, after the balls 30 are assembled into the ball separator 40, the operator must confirm these balls one by one with the naked eye, and check whether the correct number of balls are installed in each receiving groove 42 of the ball separator 40, etc. Ball 30

Such a defect becomes a cause of delay in work time
