A clamping plate 4 is provided at the left end of the workbench 1 for abutting against one side of a bearing 3. Two clamping plates 4 are provided, facing each other front and back along the width of the workbench 1, with a passage for a shaft 5 to pass through between the two clamping plates 4. A jacking support 6 is provided on the workbench to the right of the two clamping plates 4. A hydraulic cylinder 7 is provided on the left side of the jacking support 6. The cylinder body of the hydraulic cylinder 7 abuts the left side of the jacking support 6, and the piston rod of the hydraulic cylinder 7 extends leftward along the length of the workbench 1 toward the two jacking supports 6.

[0035] During disassembly, the bearing 3 and shaft 5 to be removed are hoisted onto the workbench 1, the bearing 3 is attached to the right side of the two clamps 4, and the shaft 5 passes between the two clamps 4; the hydraulic cylinder 7 is placed on the right side of the jacking support 6, the cylinder body of the hydraulic cylinder 7 abuts the left side of the jacking support 6, and the piston rod abuts the right end of the shaft 5 to the left; start the hydraulic cylinder 7, the piston rod of the hydraulic cylinder 7 extends and pushes the shaft 5 to the left along its axial direction, and the bearing 3 is held stationary by the two clamps 4, so that the shaft 5 can be ejected from the bearing 3.

[0036] Similarly, when installing, hoist the bearing 3 and the shaft 5 onto the workbench 1, and put the bearing 3 on the shaft 5, then place the hydraulic cylinder 7 according to the steps for dismantling, and push the shaft 5 into the bearing 3 through the piston rod of the hydraulic cylinder 7.

[0037] First locking bolts 8 are provided through the clamping plates 4. Two first locking bolts 8 are arranged side by side along the length of the workbench 1. The workbench 1 is provided with first adjustment slots 9 corresponding to each of the first locking bolts 8. The first adjustment slots 9 are elongated and extend forward and backward along the width of the workbench 1. The first locking bolts 8 pass through the corresponding first adjustment slots 9 and engage with the first locking nuts. After loosening the first locking bolts 8, the installation position of the clamping plates 4 can be adjusted forward and backward along the first adjustment slots 9, thereby adjusting the distance between the two clamping plates 4 according to the diameter of the shaft 5 to be removed.

[0038] A second locking bolt 10 is threaded through the jack support 6. Two second locking bolts 10 are arranged side by side along the length of the workbench 1. The workbench 1 is provided with a second adjustment slot 11 for the two second locking bolts 10 to pass through. The second adjustment slot 11 is in the shape of an elongated strip extending left and right along the length of the workbench 1. The second locking bolt 10 passes through the second adjustment slot 11 and is screwed into the second locking nut. After loosening the second locking bolt 10, the jack support 6 can be adjusted left and right along the second adjustment slot 11. This allows the installation position of the hydraulic cylinder 7 to be adjusted according to the length of the shaft 5 to be disassembled and assembled, thereby meeting the requirements for disassembling and assembling shafts 5 of different lengths.

[0039] Example 2:

[0040] like Figures 4 to 6 As shown, the difference between this embodiment and embodiment 1 is that a fixing plate 12 for clamping the bearing 3 is provided on the right side of the splint 4, and a sleeve 13 extending left and right along the length direction of the workbench 1 is welded to the right side of the splint 4, and two sleeves 13 are arranged side by side up and down. A sliding column 14 corresponding to the sleeve 13 is welded on the left side of the fixing plate 12, and the sliding column 14 is slidably installed in the corresponding sleeve 13 to provide support and guidance for the left and right movement of the fixing plate 12; a spring 15 is provided on the outer side of the sleeve 13, and the two ends of the spring 15 respectively abut against the splint 4 and the fixing plate 12, and the spring 15 pushes the fixing plate 12 to the right away from the splint 4, so that the distance between the splint 4 and the fixing plate 12 is increased, so that the bearing 3 can be placed between the splint 4 and the fixing plate 12.

[0041] A screw 16 extending left and right along the length of the workbench 1 is welded to the right side of the clamping plate 4. The screw 16 passes through the fixed plate 12 to the right and is screwed with an adjusting nut 17. Specifically, when the adjusting nut 17 is loosened, the spring 15 pushes the fixed plate 12 away from the clamping plate 4, and the bearing 3 to be disassembled can then be placed between the clamping plate 4 and the fixed plate 12. After the bearing 3 is placed in place, the adjusting nut 17 is tightened and the fixed plate 12 is pushed toward the clamping plate 4. The bearing 4 is clamped by the fixed plate 12 and the clamping plate 4, thereby providing an effective fixation for the bearing 4 and further improving the safety of the disassembly and assembly of the bearing 3.

[0042] The workbench 1 is provided with a bracket 18 that matches the hydraulic cylinder 7. Figure 6 As shown, the bracket 18 includes a base plate 19, and the base plate 19 is welded with a vertically extending stud 20. Two studs 20 are arranged side by side in the front and back direction along the width direction of the workbench 1. A supporting plate 21 for supporting the cylinder body of the hydraulic cylinder 7 is provided on the stud 20. A pressure plate 22 for pressing the cylinder body of the hydraulic cylinder 7 is also provided on the stud 20. A fastening nut 23 is screwed on the stud 20 located above the pressure plate 22.

[0043] In this embodiment, the cylinder body of the hydraulic cylinder 7 is cylindrical, and the top of the support plate 21 and the bottom of the pressure plate 22 are respectively provided with arc grooves 24 that match the outer wall of the cylinder body of the hydraulic cylinder 7. When installing the hydraulic cylinder 7, the cylinder body of the hydraulic cylinder 7 is placed on the top of the support plate 21, the pressure plate 22 is covered on the top of the cylinder body of the hydraulic cylinder 7 and the fastening nut 23 is tightened, thereby providing a stable support effect on the hydraulic cylinder 7 and improving the stability of the disassembly and assembly of the bearing 4.

[0044] A number of gaskets 25 are sleeved on the studs 20 located between the base plate 19 and the support plate 21. During specific use, gaskets 25 can be added between the base plate 19 and the support plate 21 according to the diameter of the bearing 4 to be disassembled, so as to adjust the piston rod of the hydraulic cylinder 7 and the shaft 5 to a coaxial state, so that the forces on the bearing 4 and the shaft 5 are more balanced when they are disassembled and assembled, thereby reducing wear.

[0045] Locating posts 26 are welded to the bottom of the base plate 19. Two locating posts 26 are arranged side by side in the front and back direction along the width of the workbench 1. The workbench 1 is provided with multiple locating holes 27 that match the locating posts 26. The locating holes 27 are arranged in two rows in the front and back direction. The second adjustment slot 11 is located between the two rows of locating holes 27. The multiple locating holes 27 in the same row are evenly spaced left and right along the length of the workbench 1. When installing the bracket 18, the locating posts 26 at the bottom of the base plate 19 are inserted into the locating holes 27 on the workbench 1. This prevents the bracket 18 from shifting when the hydraulic cylinder 7 is operating, and provides more stable support for the hydraulic cylinder 7 through the bracket 18. In addition, the locating posts 26 at the bottom of the base plate 19 can be inserted into different locating holes 27 according to the installation position of the jack 6 and the hydraulic cylinder 7, thereby flexibly adjusting the installation position of the bracket 18.
