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

Embodiment 1

[0082] Such as figure 2 As shown, the full ball bearing dismounting device includes a bearing support 10 , a bearing pressing piece 20 and a shock rod 30 , and the bearing pressing piece 20 includes an inner ring pressing piece 21 and an outer ring pressing piece 22 . The bearing support 10 and the bearing pressing piece 20 are used for supporting and positioning the bearing inner ring 51 and the bearing outer ring 52, and the impact rod 30 is used for removing the steel ball 53 from the full ball bearing. The full ball bearing dismounting device also includes a clamping device 40 for clamping and supporting the bearing support 10 .

[0083] Bearing support 10 is a shaft-type rotary structure, including three parts, namely support main body 11, mandrel 12 and clamping handle 13, mandrel 12 and clamping handle 13 are respectively located at the top and bottom of support main body 11. The support body 11 is provided with an annular accommodation groove 14, and the part of the ...

Embodiment 2

[0092] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the annular accommodation groove 14 on the bearing support 10 forms a steel ball avoidance space for avoiding the protruding steel ball 53; while in this embodiment, the bearing One side of the shaft seat is provided with a cavity, and the cavity forms a steel ball avoidance space, and the protruded steel ball 53 directly falls into the cavity.

Embodiment 3

[0094] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the bearing pressure piece 20 includes an inner ring pressure piece 21 and an outer ring pressure piece 22, and the inner ring pressure piece 21 and the outer ring pressure piece 22 are two In this embodiment, the inner ring pressing piece 21 and the outer ring pressing piece 22 have an integrated structure, and the bearing inner ring 51 and the bearing outer ring 52 are pressed simultaneously when tightening.

Abstract

The invention relates to a full ball bearing dismounting device and a full ball bearing dismounting method. The full ball bearing dismounting device comprises a bearing support, a bearing pressing piece and an impact rod, wherein the bearing support is provided with an inner ring supporting surface and an outer ring supporting surface; a bearing positioning structure is arranged on the bearing support and is used for positioning the full ball bearing along the radial direction; the bearing pressing piece is used for pressing a bearing outer ring and a bearing inner ring onto the bearing support, so that the bearing inner ring and the bearing outer ring are relatively fixed in the circumferential direction; the impact rod is used for applying impact force towards the bearing support to steel balls, so that the steel balls are separated from a steel ball channel on the full ball bearing; and a steel ball yielding space is formed in the bearing support and used for yielding the separatedsteel balls. The full ball bearing dismounting method comprises the steps that the full ball bearing is pressed on the bearing support through the bearing pressing piece, steel balls correspond to thesteel ball channel, and the steel balls are separated from the steel ball channel through the impact rod and enter the steel ball yielding space on the bearing support. According to the full ball bearing dismounting device and the full ball bearing dismounting method, the bearing outer ring can be prevented from being damaged during bearing dismounting.

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...
