[0002] Rollers are one of the important components of belt conveyors. Belt conveyors use a wide variety of rollers, and they are also used in large quantities, accounting for about 35% of the total cost of a belt conveyor. Under working conditions, the rollers on the belt conveyor will withstand more than 70% of the resistance, so the rollers must be flexible, safe, and reliable during operation. In actual use, due to the influence of the operating environment, some rollers on the belt conveyor will often produce abnormal noises or slow rotation, seriously affecting the normal progress of production operations. The rollers must be promptly repaired, and the shafts and bearings on the rollers must be disassembled and the bearings replaced to ensure the normal operation of the belt conveyor and the continuation of production.

[0028] In response to the above problems, an embodiment of the present application provides a belt roller bearing disassembly device, which can improve the safety of workers when disassembling the roller bearing, reduce labor intensity, and improve work efficiency.
[0029] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0030] See also Figure 1 The belt roller bearing disassembly device includes a straight cylinder 2; a disassembly groove is opened on the straight cylinder 2, and a bracket 1 is provided at the bottom of the straight cylinder 2. One end of the disassembly groove of the straight cylinder 2 is engaged and connected with a hydraulic press 3, and the other end is fixed with a baffle 14. A guide cylinder 4 is fixed on the end face of the hydraulic press 3, and an extension component 5 is provided inside the guide cylinder 4. The extension component 5 extends to the outside of the guide cylinder 4 away from the end of the hydraulic press 3 and is installed with a disassembly disk 12. The diameter of the disassembly disk 12 is smaller than the inner diameter of the belt roller 6. Limiting components 7 are symmetrically provided on both sides of the top of the straight cylinder 2, and the limiting components 7 are located on both sides of the hydraulic press 3.
[0031] In some embodiments, see Figure 3 The baffle 14 is an arc-shaped structure with an arc-shaped groove on its upper side. The wall thickness of the arc structure is smaller than that of the belt idler 6. This ensures that the bearing inside the belt idler 6 is located above the arc-shaped groove at the top of the baffle 14. During disassembly, the baffle 14 will not interfere with the disengagement of the bearing inside the belt idler 6.
[0032] In some embodiments, see Figure 2 、 4The extension component 5 includes a sliding hole 51, a sliding plate 52, a connecting screw 53, a screw nut 54, two ejector rods 55 and a pressure rod 56. The sliding hole 51 is opened on the inner wall of the guide cylinder 4. The inner wall of the sliding hole 51 is slidably connected with the sliding plate 52. The connecting screw 53 is rotatably connected to the inside of the guide cylinder 4 through a bearing. The inner wall of the sliding plate 52 is fixed with a screw nut 54 threadedly connected to the connecting screw 53. The side of the sliding plate 52 away from the hydraulic press 3 is fixed with an ejector rod 55. The end of the ejector rod 55 is fixed with a pressure rod 56. The pressure rod 56 extends to the outside of the guide cylinder 4 and is installed with a disassembly disk 12.
[0033] In some embodiments, the surface of the straight cylinder 2 is rotatably connected to a linkage shaft 8 through a bearing, one end of the linkage shaft 8 is fixed with a first bevel gear 9, the surface of the connecting screw 53 is fixed with a second bevel gear 10, the first bevel gear 9 is meshed with the second bevel gear 10, and the other end of the linkage shaft 8 is fixed with a handwheel 11.
[0034] Turning the handwheel 11 rotates the linkage shaft 8 and the first bevel gear 9. Since the first bevel gear 9 is meshed with the second bevel gear 10, the second bevel gear 10 and the connecting screw 53 rotate synchronously. After the connecting screw 53 cooperates with the screw nut 54, the sliding plate 52 slides along the inner wall of the sliding hole 51. At the same time, the two ejector rods 55 move horizontally to make the pressure rod 56 and the rubber pad 13 close to the bearing position of the belt roller 6. Therefore, the bearings of belt rollers 6 of different lengths can be disassembled by adjusting the horizontal position of the pressure rod 56.
[0035] In some embodiments, the limiting assembly 7 includes a vertical plate 71, a screw 72 and a gasket 73. The vertical plate 71 is fixedly arranged on both sides of the top of the straight cylinder 2. The inner wall of the vertical plate 71 is threadedly connected with a screw 72. A gasket 73 is fixedly provided at one end of the screw 72 close to the hydraulic press 3. By rotating the two screws 72 in sequence, the two gaskets 73 are used to fix and limit the hydraulic press 3, so that the device can be suitable for installing hydraulic presses 3 of various specifications.
[0036] In some embodiments, a rubber pad 13 is fixedly provided on one side of the disassembly disk 12 , and the rubber pad 13 can reduce the wear of the disassembly disk 12 on the belt disassembly bearing.
[0037] Working process of this application:
[0038] When using the present invention, first place the belt idler 6 whose bearing needs to be removed at one end inside the straight cylinder 2, and place the bearing to be removed toward the pressure rod 56, then place the hydraulic press 3 on the other side inside the straight cylinder 2, and turn the two screws 72 in sequence to make the two gaskets 73 fix the hydraulic press 3, then turn the hand wheel 11 to rotate the linkage shaft 8 and the first bevel gear 9. Since the first bevel gear 9 is meshed with the second bevel gear 10, the second bevel gear 10 and the connecting screw rod 53 rotate synchronously. After the connecting screw rod 53 cooperates with the screw nut 54, the sliding plate 52 slides along the inner wall of the sliding hole 51. At the same time, the two ejector rods 55 move horizontally to make the pressure rod 56 and the rubber pad 13 close to the bearing position of the belt idler 6. Finally, turn on the control switch of the hydraulic press 3 to make the pressure rod 56 squeeze the bearing in the belt idler 6 to complete the disassembly of the roller bearing.
