いては、組立は不可能であった。Conventionally, assembling devices for double row ball bearings have been described, for example, in Japanese Utility Model Application Publication No. 56-44224.
The device described in this publication is useful for double-row ball bearings with a relatively small groove center distance P as shown in Figure 1, but in this type of device, the groove center distance P For large bearings, the inner and outer rings are offset relative to each other, and after inserting the specified number of balls for two rows of grooves into the gap formed between the inner and outer rings, the centers of the inner and outer rings are Even if the inner or outer ring is displaced to match,
Although the ball fits into the gap between the lower grooves, it may be difficult to fit into the upper gap, and it has been impossible to assemble balls with a particularly large distance between the groove centers.

。The device of this invention has almost no relation to the distance between the groove centers, and can be used to assemble ball bearings with a particularly large distance between the groove centers. After inserting a specified number of balls into the gap between the groove and the bay on the lower side of the bearing, the arc length is shorter than the circumferential length of the unoccupied part of the ball after the construction of the double row ball bearing. Place a crescent-shaped ball bearing member with a cylindrical shape in the above-mentioned gap, and after inserting the specified number of nine balls into the gap between the upper groove and the bay of the double row ball bearing, place the balls on the ball bearing member. With the centers of the inner and outer rings of the bearing aligned and the balls held in the gaps between the grooves of the inner and outer rings of the double-row ball bearing, the ball bearing member is rotationally displaced to a space where the balls are not lined up. This is an assembly device for a double row ball bearing, which is characterized in that the bearing is returned upward from this space.

It's K. The ball bearing member 6 is a crescent-shaped member, and its arc length is shorter than the circumferential length of the unoccupied portion of the ball after the construction of the double-row ball bearing, and its thickness is determined to improve the strength and the length of the double-row ball bearing 3. It is determined based on the distance between the groove centers, but in cases other than double row ball bearings where the distance between the groove centers is small, only the strength needs to be considered. Also, the width in the diametrical direction is the inner ring of a double row ball bearing! It is determined based on the gap formed between the outer diameter surface and the inner diameter surface of the outer ring 31. The ball leveling device f8 is configured to be able to move vertically in the figure by a drive mechanism such as a fluid cylinder (not shown), and includes a ball leveling part 81 that is curved according to the size of the double row ball bearing. There is. The suppression device 9 is the left supply pipe 10 of the main body 2 in the figure.

装入された規定数の玉おをはぼ覆う位置にある。Next, the assembly of a double row ball bearing using the above assembly device will be described. In the pre-process, the inner ring holder and outer ring 31 of the double-row ball bearing are placed on the support stand 1 so that their centers are relatively offset, and the gap below the placed double-row ball bearing is As shown in FIG. 3, a specified number of balls are loaded and arranged on the crescent-shaped protrusion ll, and then transferred to a predetermined position in the apparatus. Therefore, the above-mentioned device inserts a specified number of balls between the upper grooves of the double-row ball bearing in the mounted state. The ball bearing member 6, which has been displaced as an inner ring guide with respect to the inner ring 32 of the double row ball bearing, which has been shifted to a predetermined position by the support base 1, descends into the gap formed between the inner ring 32 and the outer ring 31 of the double row ball bearing. . It is necessary to adjust this lowering position in advance so that the balls can be easily lined up in the upper groove. FIG. 4 shows this ball bearing member 6 and the inner ring 32.
Although the relative positions of the outer ring 31 and the outer ring 31 in the horizontal direction are shown, the ball bearing member 6 is in a position that completely covers the specified number of balls that have already been inserted between the lower grooves in the previous step.
