Description

Technical Field

[0001] This utility model relates to a bearing disassembly device. Background Technology

[0002] Currently, bearings are typically tightly fitted onto a shaft. When the bearing or shaft is damaged, or during routine maintenance, a bearing removal device is needed to remove the bearing from the shaft. For example, Chinese Patent CN112775899A discloses a bearing removal device that involves placing the bearing against the edge of an opening groove and passing the shaft through the groove, then using a lifting mechanism to push the shaft out of the bearing, thus completing the removal. However, this bearing removal device is limited by the size of the opening groove and can only remove bearings of a fixed size, making it unsuitable for disassembling bearings of different sizes, thus limiting its applicability.

[0034] like Figures 1-4 As shown, a bearing disassembly device includes a frame 100, a pressure applying mechanism 200, an adjusting mechanism 300, and multiple trays 1;

[0035] The frame 100 is provided with a through hole 3 for the shaft 2 to pass through;

[0036] The support plates 1 are arranged sequentially along the circumference of the through holes 3 and are slidably connected to the frame 100 along the radial direction of the through holes 3. The inner end of the support plate 1 is used to abut against the lower end face of the bearing 4 mounted on the shaft 2 to support the bearing 4.

[0037] The adjustment mechanism 300 is connected to the frame 100, and the adjustment mechanism 300 is connected to the tray 1 and is used to drive the tray 1 to move radially into place;

[0038] The pressure mechanism 200 is connected to the frame 100 and is used to actuate against the shaft 2 and push the shaft 2 downward along the axial direction of the shaft 2, thereby separating the shaft 2 from the bearing 4.

[0039] Specifically, firstly, based on the dimensions of the bearing 4 and the shaft 2, the adjusting mechanism 300 drives the support plate 1 to move radially into position. Then, the lower end face of the bearing 4 abuts against the inner end of the support plate 1, allowing the shaft 2 to pass through the through hole 3. At this point, the support plate 1 holds the bearing 4. Then, the pressing mechanism 200 abuts against the shaft 2 and pushes the shaft 2 downward, thereby separating the shaft 2 from the bearing 4. The adjusting mechanism 300 can drive the support plate 1 to move radially, thus enabling the support plate 1 to hold bearings 4 of different sizes, and thus allowing the disassembly of bearings 4 of different sizes. In this embodiment, the support plate 1 has six holes evenly distributed circumferentially, the through holes 3 extend vertically, and the inner end of the support plate 1 is the end near the center of the through hole 3.

[0040] like Figures 1-4 As shown, the adjustment mechanism 300 may include a drive ring 5 and an actuation mechanism;

[0041] The drive ring 5 is rotatably connected to the frame 100, and the drive ring 5 is provided with a plurality of drive grooves 6;

[0043] The actuation mechanism is connected to the frame 100. The actuation mechanism is connected to the drive ring 5 and is used to drive the drive ring 5 to rotate, thereby driving the support plate 1 to move radially along the through hole 3 through the cooperation of the drive groove 6 and the transmission pin 7.

[0044] like Figures 1-4As shown, the actuation mechanism may include a worm gear tooth 8 disposed on the drive ring 5 and a worm 9 rotatably connected to the frame 100 and meshing with the worm gear tooth 8. A handwheel 10 is connected to the worm 9. Specifically, the handwheel 10 can drive the worm 9 to rotate, and then the drive ring 5 can be driven to rotate through the cooperation between the worm 9 and the worm gear tooth 8.

[0045] like Figures 1-4 As shown, the frame 100 may include a mounting plate 11;

[0046] The mounting plate 11 is provided with a sleeve portion 12, and the through hole 3 is provided on the inner side of the sleeve portion 12;

[0047] The drive ring 5 is rotatably sleeved on the sleeve portion 12 and located below the mounting plate 11;

[0048] The lower end of the sleeve portion 12 is connected to a cover plate 13, which abuts against the lower end face of the inner circumference of the drive ring 5, thereby restricting the rotation of the drive ring 5 on the sleeve portion 12; in this embodiment, the worm gear 9 is rotatably connected to the mounting plate 11 and located below the mounting plate 11.

[0049] like Figures 1-4 As shown, the support plate 1 is slidably connected to the mounting plate 11 along the radial direction of the through hole 3 and is located above the mounting plate 11;

[0050] The mounting plate 11 is provided with a waist-shaped groove 14 corresponding to the support plate 1. The transmission pin 7 on the support plate 1 passes through the corresponding waist-shaped groove 14 and then engages with the drive groove 6 on the drive ring 5.

[0051] like Figures 1-4 As shown, the upper end of the mounting plate 11 is connected to a limiting seat 15 corresponding to the support plate 1. The limiting seat 15 is provided with a sliding hole, and the support plate 1 is slidably disposed in the corresponding sliding hole in the limiting seat 15.

[0052] like Figures 1-4 As shown, a locking bolt 16 can be connected to the limiting seat 15. The locking bolt 16 is used to tighten the support plate 1 against the support plate 1 and lock the position of the support plate 1 when the support plate 1 is driven to move radially into place.

[0053] like Figures 1-4 As shown, the frame 100 may further include a main body 17 and a support frame 18;

The pressure block 20 is connected to the hydraulic cylinder 19, and the hydraulic cylinder 19 is connected to the frame 100 and is used to drive the pressure block 20 to move downward to abut against the shaft 2 so as to push the shaft 2 downward. In this embodiment, the hydraulic cylinder 19 is connected to the support frame 18.

[0057] like Figure 3 As shown, the pressure block 20 may be provided with a conical groove 21 facing downward. The conical groove 21 is used to abut against the upper end of the shaft 2 to prevent the pressure block 20 from slipping off the shaft 2 when the shaft 2 is pressed down.

[0058] In summary, firstly, based on the dimensions of the bearing 4 and the shaft 2, the adjusting mechanism 300 drives the support plate 1 to move radially into position. Then, the lower end face of the bearing 4 abuts against the inner end of the support plate 1, allowing the shaft 2 to pass through the through hole 3. At this point, the support plate 1 holds the bearing 4. Then, the pressing mechanism 200 abuts against the shaft 2 and pushes the shaft 2 downward, thereby separating the shaft 2 from the bearing 4. The adjusting mechanism 300 can drive the support plate 1 to move radially, thus enabling the support plate 1 to hold bearings 4 of different sizes, and thus allowing the disassembly of bearings 4 of different sizes.
