Abstract
Description
Technical Field
[0001] The present application relates to the field of bearing disassembly and assembly, and in particular to a bearing disassembly and assembly device. Background Art
[0002] Bearings are precision parts widely used in mechanical equipment. They are mainly used to support rotating shafts or swinging shafts and ensure their stable and accurate rotation or swinging, while bearing and transmitting axial and radial loads. Bearings play a vital role in mechanical equipment and directly affect the working efficiency, lifespan and operating stability of the equipment.
[0003] However, with the operation and use of mechanical equipment, the bearings therein will gradually wear out. When the bearings are worn to a certain extent, they can no longer be used and need to be replaced in time.
[0004] At present, when replacing bearings, simple tools such as iron bars, pads and hammers are often used to knock the bearings to disassemble and install them. However, the bearing and the bearing mounting holes on the bearing seat are tightly matched, and the hardness of the bearing and the bearing seat is also high, so it takes a lot of effort to remove the bearing from the bearing seat or install the bearing on the bearing seat. In this process, it is easy to damage the bearing and the bearing seat. Utility Model Content
[0005] The present application provides a bearing disassembly and assembly device to at least solve the problem of disassembling and installing the bearing without damaging the bearing and the bearing seat. The technical solution of the present application is as follows:
[0006] The present application provides a bearing disassembly and assembly device, including a clamping part, a screw and a nut. The clamping part includes a fixing part and two clamping parts. The two clamping parts are spaced apart and located on one side of the fixing part, and one end is connected to the fixing part. The two clamping parts are used to clamp a bearing seat, and an old bearing is installed in the bearing seat. One end of the screw is connected to the fixing part, and the other end extends to a side of the clamping part away from the fixing part. The screw is used to allow the old bearing and the new bearing to be inserted thereon. The nut is sleeved on the screw and is threadedly connected to the screw.
[0007] According to the above technical means, the bearing disassembly and assembly device provided in the embodiment of the present application, when in use, first pass the screw through the inner ring of the old bearing, and then make the inner sides of the two clamping parts clamp into the outer side of the bearing seat. Then, from the side of the screw away from the clamping part, the new bearing is sleeved on it. Then, on the side of the screw away from the clamping part, the nut is threadedly connected with the screw. Turn the nut so that the nut moves and rotates relative to the screw, and the nut gradually moves in the direction close to the clamping part. Then the nut contacts the new bearing, and the nut applies a force in the direction close to the clamping part to the new bearing, so that the nut and the new bearing move in this direction together. Then the new bearing contacts the old bearing, and the new bearing applies a force in the direction close to the clamping part to the old bearing, so that the nut, the new bearing and the old bearing move in this direction together. Slowly, under the action of the force applied by the nut, the old bearing moves out of the mounting hole and enters the U-shaped slot. At the same time, the new bearing moves into the mounting hole and fits tightly with the bearing seat. Thus, the disassembly of the old bearing and the installation of the new bearing are completed.
[0008] In a possible implementation, the bearing disassembly and assembly device further includes a first gasket. The first gasket is sleeved on the screw, located on a side of the nut close to the clamping member, and is detachably connected to the screw.
[0009] According to the above technical means, friction between the old bearing and the new bearing can be prevented during the movement, thereby ensuring the integrity of the old bearing and the new bearing.
[0010] In a possible implementation, the first gasket includes a first connection portion and two first protrusions. The first connection portion is provided with a first avoidance hole, and the first connection portion is sleeved on the screw through the first avoidance hole. The two first protrusions are located on both sides of the first connection portion along the axis direction of the avoidance hole. The two first protrusions are arranged around the periphery of the avoidance hole.
[0011] According to the above technical means, the axis center of the new bearing and the axis center of the old bearing can be located on the same straight line, so that the new bearing can be moved into the mounting hole at a more appropriate position.
[0012] In a possible implementation, the bearing disassembly and assembly device further includes a second gasket. The second gasket is sleeved on the screw and is located on a side of the first gasket away from the clamping member. The first gasket and the second gasket are used to be located on both sides of the new bearing respectively.
[0013] According to the above technical means, friction between the new bearing and the nut during movement can be prevented, thereby ensuring the integrity of the new bearing.
[0014] In a possible implementation, the second gasket includes a second connection portion and a second protrusion. The second connection portion is provided with a second avoidance hole, and the second connection portion is sleeved on the screw through the second avoidance hole. The second protrusion is located on a side of the second connection portion close to the clamping portion along the axial direction of the avoidance hole. The second protrusion is arranged around the periphery of the avoidance hole.
[0015] According to the above technical means, it can be further ensured that the axis of the new bearing can be located on the same straight line as the axis of the old bearing.
[0016] In a possible implementation manner, the bearing disassembly and assembly device further includes a third gasket. The third gasket is sleeved on the screw and is located between the second gasket and the nut.
[0017] According to the above technical means, the rotational stress of the nut can be reduced as much as possible, preventing various components from being damaged and affecting the service life of the new bearing and the bearing disassembly and assembly device.
[0018] In a possible implementation, a receiving groove is provided on one side of the fixing portion close to the two clamping portions, and one end of the screw is connected to the bottom of the receiving groove.
[0019] According to the above technical means, a storage space can be provided for the replaced old bearing.

DETAILED DESCRIPTION
[0036] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.
[0037] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.
[0038] Bearings are widely used in modern industry and mechanical equipment. They are used in most fields that require the support of rotating parts or the reduction of friction. Bearings play a vital role in reducing wear, improving efficiency, ensuring accuracy and extending equipment life.
[0039] The installation and removal of bearings is a delicate operation process. The correct method can ensure the working performance of the bearing, extend the service life and prevent damage. Generally, the fit between the bearing and the bearing seat is relatively tight, which makes the removal and installation of the bearing difficult. It takes a lot of force to replace the bearing. However, forceful removal and installation of the bearing will cause certain damage to the bearing and the bearing seat.
[0040] Furthermore, generally, the steps of disassembling and installing the bearing are performed separately, which takes a long time and makes the efficiency of disassembling and installing the bearing low.
[0041] Based on this, the embodiment of the present application provides a bearing disassembly and assembly device, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the overall structure of a bearing disassembly and assembly device 100 provided by the present invention. The bearing disassembly and assembly device 100 may include a clamping member 10, a screw 20 and a nut 30.
[0042] The clamping member 10 may include a fixing portion 11 and two clamping portions 12. The two clamping portions 12 are spaced apart and located at one side of the fixing portion 11, and one end is connected to the fixing portion 11. The two clamping portions 12 are used to clamp a bearing seat, and an old bearing is installed in the bearing seat.
[0043] The clamping part 12 and the fixing part 11 form a U-shaped clamping groove. When in use, the inner side of the U-shaped clamping groove, that is, the two sides where the two clamping parts 12 are close to each other, clamps the outer side of the bearing seat. The bearing seat can be stably clamped on the clamping part 12. Because the old bearing is installed in the bearing seat, the position of the old bearing is relatively stable relative to the clamping part 10.
[0044] For example, a mounting hole may be provided on the bearing seat, and the mounting hole is used to mount the bearing. The bearing is tightly matched with the bearing seat through the mounting hole.
[0045] For example, Figure 2 As shown, Figure 2 This is a partial structural diagram of a bearing disassembly and assembly device 100 provided by the utility model. The overall shape of the clamping portion 12 can be cylindrical, and can also be set to other shapes according to specific circumstances.
[0046] like Figure 1As shown, one end of the screw 20 is connected to the fixing portion 11, and the other end extends to the side of the clamping portion 12 away from the fixing portion 11. The screw 20 is used to allow the old bearing and the new bearing to be inserted thereon. The nut 30 is sleeved on the screw 20 and is threadedly connected to the screw 20.
[0047] The screw 20 first passes through the inner ring of the old bearing and then passes through the inner ring of the new bearing, thereby limiting the positions of the old bearing and the new bearing to prevent them from shifting and falling off during the process of disassembly and installation.
[0048] The bearing disassembly and assembly device 100 provided in the embodiment of the present application is as follows: Figure 1 As shown, when in use, firstly, the screw 20 is passed through the inner ring of the old bearing, and then the inner sides of the two clamping parts 12 are clamped into the outer side of the bearing seat. Then, the new bearing is sleeved on the side of the screw 20 away from the clamping part 10. Then, the nut 30 is threadedly connected with the screw 20 on the side of the screw 20 away from the clamping part 10.
[0049] Rotate the nut 30 so that the nut 30 moves and rotates relative to the screw 20, and the nut 30 gradually moves toward the direction close to the clamping part 10. Then the nut 30 contacts the new bearing, and the nut 30 applies a force to the new bearing in the direction close to the clamping part 10, so that the nut 30 and the new bearing move together in this direction. Then the new bearing contacts the old bearing, and the new bearing applies a force to the old bearing in the direction close to the clamping part 10, so that the nut 30, the new bearing and the old bearing move together in this direction. Slowly, under the action of the force applied by the nut 30, the old bearing moves out of the mounting hole and enters the U-shaped slot. At the same time, the new bearing moves into the mounting hole and fits tightly with the bearing seat. This completes the removal of the old bearing and the installation of the new bearing.
[0050] In some embodiments, Figure 1 As shown, the bearing disassembly and assembly device 100 may further include a first gasket 40. The first gasket 40 is sleeved on the screw 20, located on a side of the nut 30 close to the clamping member 10, and is detachably connected to the screw 20.
[0051] Specifically, the first gasket 40 is located between the old bearing and the new bearing, which can prevent friction from occurring during the movement between the old bearing and the new bearing, thereby ensuring the integrity of the old bearing and the new bearing.
[0052] In some embodiments, Figure 3 As shown, Figure 3 Schematic diagram of the structure of the first gasket 40 provided by the utility model, the first gasket 40 may include a first connecting portion 41 and two first protrusions 42. The first connecting portion 41 is provided with a first avoidance hole, and the first connecting portion 41 is sleeved on the screw 20 ( Figure 1The two first protrusions 42 are located on both sides of the first connection portion 41 along the axial direction of the avoidance hole. The two first protrusions 42 are arranged around the periphery of the avoidance hole.
[0053] The two first protrusions 42 can respectively fit tightly with the inner ring of the old bearing and the inner ring of the new bearing.
[0054] For example, the two first protrusions may be in the shape of a ring, and the centers of the two first protrusions are located on the same straight line, so that the axis of the new bearing and the axis of the old bearing are located on the same straight line, so that the new bearing can be moved into the mounting hole at a more appropriate position.
[0055] In other embodiments, the first gasket may include the first connecting portion but does not include the two first protrusions. In this case, the first gasket can also prevent friction between the old bearing and the new bearing during the movement.
[0056] In other embodiments, the first gasket may include a first connecting portion and a first protrusion. The first protrusion is located on a side of the first connecting portion away from the clamping portion. In this case, the first protrusion can be tightly matched with the inner ring of the new bearing, so that the new bearing is in a more suitable position for installation.
[0057] In some embodiments, Figure 1 As shown, the bearing disassembly and assembly device 100 may further include a second gasket 50. The second gasket 50 is sleeved on the screw 20 and is located on a side of the first gasket 40 away from the clamping member 10. The first gasket 40 and the second gasket 50 are used to be located on both sides of the new bearing respectively.
[0058] The second gasket 50 is located between the new bearing and the nut 30, and can prevent friction between the new bearing and the nut 30 during movement, thereby ensuring the integrity of the new bearing.
[0059] In some embodiments, Figure 4 As shown, Figure 4 Schematic diagram of the structure of the second gasket 50 provided by the utility model, the second gasket 50 may include a second connecting portion 51 and a second protruding portion 52. The second connecting portion 51 is provided with a second avoidance hole, and the second connecting portion 51 is sleeved on the screw 20 ( Figure 1 The second protrusion 52 is located on one side of the second connection portion 51 close to the clamping portion 12 along the axial direction of the avoidance hole. The second protrusion 52 is arranged around the periphery of the avoidance hole.
[0060] The second protrusion 52 can be tightly matched with the inner ring of the new bearing.
[0061] For example, the second protrusion may be in the shape of a ring, and the center of the circle of the second protrusion and the center of the circle of the first protrusion are on the same straight line, so that the axis of the new bearing and the axis of the old bearing are on the same straight line.
[0062] Protruding washers are provided on both sides of the new bearing, so that both sides of the new bearing can be supported in position, further ensuring that the axis of the new bearing can be located on the same straight line as the axis of the old bearing.
[0063] In other embodiments, the second gasket may include the second connection portion but does not include the second protrusion. In this case, the second gasket can also prevent friction between the new bearing and the nut during the movement.
[0064] In other embodiments, the shapes of the two first protrusions 42 and the second protrusions 52 may also be other shapes, or may be discontinuously arranged, as long as they can fit tightly with the inner rings of the old bearing and the new bearing so that the axes of the new bearing and the old bearing are located on the same straight line.
[0065] For example, Figure 3 and Figure 4 As shown, the first connection portion 41 and the second connection portion 51 may be cylindrical in shape, or other shapes may be selected according to specific circumstances.
[0066] In some embodiments, Figure 1 As shown, the bearing disassembly and assembly device 100 may further include a third gasket 60. The third gasket 60 is sleeved on the screw 20 and is located between the second gasket 50 and the nut 30.
[0067] The third gasket 60 is located between the second gasket 50 and the nut 30. Since the nut 30 rotates relative to the screw 20 while moving relative to the screw 20, the second gasket 50 is subjected to the rotational stress generated by the nut 30 and rubs against the nut 30. This causes certain friction damage to the second gasket 50 and the nut 30. At the same time, the second gasket 50 may also rotate relative to the screw 20 due to the rotational stress of the nut 30, so there will be certain friction between the second gasket 50 and the new bearing, thereby damaging the new bearing.
[0068] Therefore, the presence of the third gasket 60 can reduce the rotational stress of the nut 30 as much as possible, prevent various components from being damaged, and affect the service life of the new bearing and the bearing disassembly and assembly device 100.
[0069] Exemplarily, the first gasket 40, the second gasket 50 and the third gasket 60 are close to the inner side of the screw 20, and can be smooth, so as not to rotate relative to the screw 20. This can prevent friction damage between the components due to rotation.
[0070] In some embodiments, Figure 2 As shown, a receiving groove 1101 may be provided on one side of the fixing portion 11 close to the two clamping portions 12. One end of the screw 20 is connected to the bottom of the receiving groove 1101.
[0071] When the old bearing is separated from the bearing seat under the force applied by the nut 30, it can enter the receiving groove 1101. The receiving groove 1101 can provide a receiving space for the replaced old bearing, and can also limit the position of the old bearing to a certain extent, preventing the old bearing from shaking at will and causing unnecessary friction with the screw 20 and the clamping member 10 to cause damage.
[0072] For example, Figure 2 As shown, the shape of the receiving groove 1101 can be cylindrical, so that it can better fit the shape of the old bearing and can better accommodate the disassembled old bearing. The shape of the receiving groove 1101 can be selected from other shapes according to specific circumstances.
[0073] For example, Figure 1 As shown, the type of nut 30 can be a hexagonal nut. The shape of the hexagonal nut is a hexagonal column, and each face can be tightened or loosened with a wrench, a socket wrench or an Allen wrench. It is more convenient for the staff to operate the nut 30 and apply force to it.
[0074] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
