玉軸受の組立方法
Document Type and Number:
Japanese Patent JP7085430
Kind Code:
B2
Abstract:
To provide an assembling method of a ball bearing which can enhance a charging rate of balls assembled between an outer ring and an inner ring, and can efficiently perform the assembling work of the balls.SOLUTION: Firstly, two pivoting balls 13 are arranged between a raceway groove 11a of an outer ring 11 and a raceway groove 12a of an inner ring 12 with a prescribed angle interval θ, then regions A in each of which a clearance in a radial direction between the outer ring 11 and the inner ring 12 are formed at two points in a peripheral direction by applying loads in a direction in which the radial clearance is narrowed to the outer ring 11 and the inner ring 12 in the vicinity of a center position of the angle interval θ between both the pivoting balls 13, and the remaining balls 13 are inputted between the outer ring 11 and the inner ring 12 from the regions A at the two points. By this constitution, the charging rate of the balls 13 can be enhanced more than that by a normal assembling method of a deep groove ball bearing, and the balls 13 can be efficiently assembled because the number of points for inputting the balls 13 is large as compared with a conventional method using a jig.SELECTED DRAWING: Figure 2
