Full ball bearing removal device and full ball bearing removal method

Abstract

The invention relates to a full ball bearing dismounting device and a full ball bearing dismounting method. The full ball bearing dismounting device includes: a bearing support, the bearing support has an inner ring support surface and an outer ring support surface; a bearing positioning structure is provided on the bearing support for radial positioning of the full ball bearing; Press the outer ring of the bearing and the inner ring of the bearing onto the bearing support so that the inner ring of the bearing and the outer ring of the bearing are relatively fixed along the circumferential direction; the impact rod is used to exert an impact force on the steel ball towards the bearing support to make the steel ball It escapes from the steel ball channel on the full ball bearing; the bearing support is provided with a steel ball avoidance space for avoiding the protruded steel ball. The disassembly method of the full ball bearing is to press the full ball bearing onto the bearing support through the bearing pressure piece, so that the steel ball corresponds to the steel ball channel, and use the impact rod pair to make the steel ball escape from the steel ball channel and enter the bearing support The steel ball on it avoids the space. The above solution can avoid damage to the outer ring of the bearing when the bearing is disassembled.

Description

technical field [0001] The invention relates to a full ball bearing dismounting device and a full ball bearing dismounting method. Background technique [0002] Full ball bearing refers to the bearing with more steel balls installed between the bearing inner ring and the bearing outer ring. Even if these steel balls contact in sequence, it is enough to maintain the coaxial relationship between the bearing inner ring and the bearing outer ring. A novel bearing disclosed in the Chinese patent literature with the publication number CN104121279A. Compared with deep groove ball bearings, full ball bearings have no cage, which can avoid the impact of the cage on the bearing rotation, and are especially suitable for workplaces that bear heavy radial loads. [0003] However, due to the large number of steel balls, the steel balls cannot be directly loaded into the bearing raceway from the space between the inner ring and the outer ring of the bearing. Therefore, if figure 1 As sh...

Problems solved by technology

[0004] However, since the steel balls 103 are forced into the bearing raceway when the full ball bearing is assembled, it is difficult to remove the steel balls 103 of the full ball bearing after assembly. At present, destructive methods are often used to disassemble the full ball bearing, such as The bearing outer ring 102 is cut by wire cutting technology, which will damage the bearing outer ring 102, and the bearing outer ring 102 cannot be reassembled, which increases the maintenance cost
