Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of disassembly tools, in particular to a bearing seat disassembly device. Background Art
[0002] Bearings are an important component in mechanical equipment. Their main function is to support mechanical rotating bodies, reduce friction coefficients during movement, and ensure rotation accuracy. Bearings come in many types according to their operating conditions and their own structures. Among them, outer spherical ball bearings with seats are composed of outer spherical ball bearings with seals on both sides and cast bearing seats. The outer ring of the outer spherical ball bearing is provided with a truncated spherical outer surface, and the inner side of the bearing seat is provided with a concave spherical surface. The two can be matched to achieve automatic self-alignment, so outer spherical ball bearings with seats are widely used in mechanical equipment.
[0003] When the outer spherical ball bearing with seat is used in the stacker's traveling wheel assembly, the outer spherical ball bearing with seat is sleeved on the outside of the drive shaft. Since the stacker's traveling wheel will vibrate during traveling, the bearing seat will be subjected to uneven force, resulting in stress concentration. Therefore, the bearing seat often glues to the mounting support plate at the position for installing the bearing seat on the stacker's mounting support plate, making it difficult to remove the bearing seat.
[0004] In the prior art, when replacing and disassembling a damaged bearing seat, it is usually necessary to spray a rust loosening agent on the bearing seat installation position, then repeatedly hit different positions of the bearing seat with a rubber hammer, and finally remove the bearing seat with a crowbar or even gas cutting. Although the bearing seat removal method in the prior art can achieve disassembly, it uses many tools, is time-consuming and labor-intensive, and is not convenient enough. Utility Model Content

[0012] In one embodiment of the present invention, the clamping block is in the shape of a spherical table, and the outer contour of the clamping block is in the shape of an arc.

[0031] Among them, one end of the active rod 6 abuts against the axial end surface of the driving shaft 2. When the active rod 6 is screwed and rotated, the active rod 6 drives the connecting plate 5 and the support rod 4 to move to the side away from the driving shaft 2, and the support rod 4 drives the outer spherical bearing 3 with a seat to separate from the mounting support plate 1 and the driving shaft 2.
[0032] When the bearing seat disassembly device is used, the operator drills a hole on the outer spherical bearing 3 with a seat, and installs the support rod 4 to clamp the outer spherical bearing 3 with a seat; then the active rod 6 is threadedly connected with the connecting plate 5, and the connecting plate 5 is sleeved and connected to the outside of the support rod 4; the operator screws the active rod 6, and the active rod 6 rotates on the shaft end surface close to the drive shaft 2. After the active rod 6 abuts against the drive shaft 2, the active rod 6 is continued to be screwed, and the forward direction of the active rod 6 is blocked by the drive shaft 2, thereby forcing the connecting plate 5 to move in the direction away from the drive shaft 2. When the connecting plate 5 moves, it drives the outer spherical bearing 3 with a seat to detach from the mounting support plate 1 and the drive shaft 2 through the support rod 4, and the disassembly of the outer spherical bearing 3 with a seat is completed. The bearing seat disassembly device is easy to use, and the disassembly process saves time and effort, and improves the efficiency of disassembly and replacement.
[0033] In this embodiment, refer to Figure 2 As shown, preferably, one end of the support rod 4 is provided with an insert portion 41 and a block 42 that are interconnected, the insert portion 41 is configured to be inserted into the outer spherical bearing 3 with a seat, the width of the block 42 is greater than the thickness, and after the block 42 is inserted into the outer spherical bearing 3 with a seat and rotated 90 degrees, the block 42 is clamped in the outer spherical bearing 3 with a seat.
[0034] In this embodiment, specifically, the operator first breaks open the retaining frame inside the outer spherical bearing 3 with a seat, and then inserts the insertion portion 41 and the block 42 into the retaining frame in the thickness direction of the block 42. After the insertion, the support rod 4 is rotated 90 degrees, and the width direction of the block 42 is locked inside the retaining frame, so that the block 42 cannot directly slide out of the outer spherical bearing 3 with a seat, thereby completing the clamping connection between the support rod 4 and the outer spherical bearing 3 with a seat.
[0035] In this embodiment, preferably, the block 42 is in the shape of a spherical table, and the outer contour of the block 42 is in the shape of an arc.

[0047] By providing an arc chamfer on the outer side of the connecting plate 5, collision with sharp parts can be avoided, thereby improving the safety of operators.
[0048] The implementation principle of this embodiment is as follows: when the bearing seat disassembly device is in use, the operator drills a hole on the outer spherical bearing 3 with a seat, and inserts the support rod 4 into the retaining frame of the outer spherical bearing 3 with a seat, and then rotates the support rod 4 90 degrees to clamp the block 42 in the outer spherical bearing 3 with a seat; then the active rod 6 is threadedly connected to the connecting plate 5, and the connecting plate 5 is sleeved and connected to the outside of the support rod 4; the operator screws the active rod 6, and the active rod 6 rotates close to the axial end face of the drive shaft 2. After the active rod 6 abuts against the drive shaft 2, the active rod 6 is continued to be screwed, and the forward direction of the active rod 6 is blocked by the drive shaft 2, thereby forcing the connecting plate 5 to move in the direction away from the drive shaft 2. When the connecting plate 5 moves, it drives the outer spherical bearing 3 with a seat to detach from the mounting support plate 1 and the drive shaft 2 through the support rod 4, thereby completing the disassembly of the outer spherical bearing 3 with a seat.
