Description

Technical Field

[0001] This utility model belongs to the technical field of bearing disassembly equipment, specifically relating to a bearing disassembly device for a hydraulic motor. Background Technology

[0002] The bearings of hydraulic motors are usually interference-fitted to the outside of the rotating shaft or the inside of the hydraulic motor housing. The disassembly of existing hydraulic motor bearings is often done manually. For bearings on the outside of the rotating shaft, the bearing is removed from the rotating shaft by directly hitting it with a hammer. For bearings on the inside of the housing, a copper rod is needed and a hammer is used to hit them to remove them. However, this disassembly method is laborious, slow, and can easily damage the bearing and surrounding parts, making it impractical. Utility Model Content

[0003] The purpose of this invention is to provide a bearing disassembly device for hydraulic motors, so as to solve the problems of laborious and impractical disassembly methods for hydraulic motor bearings.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A bearing removal device for a hydraulic motor includes a mounting bracket and a screw that screws through the mounting bracket. A fixing plate is fixedly mounted at one end of the screw, and a movable seat is rotatably sleeved on the outside of the fixing plate. Two top plates are symmetrically rotatably connected to the end of the movable seat. Two sliding columns are symmetrically slidably connected on both sides of the screw on the mounting bracket. Rotating rods are rotatably connected inside each of the two sliding columns, and baffles are fixedly mounted at the ends of each of the two rotating rods.

[0006] Preferably, a guide rod is fixedly installed at one end of the movable seat, and one end of the guide rod slides through the mounting frame.

[0007] Preferably, one end of the lead screw has a hexagonal groove.

[0008] Preferably, a threaded cylinder is fixedly installed on the outside of the movable seat, and a threaded sleeve is screwed onto the outside of the threaded cylinder, with one end of the threaded sleeve slidably fitted onto the outside of the two top plates.

[0009] Preferably, the mounting bracket has two sliders slidably connected inside, and the two sliders are respectively fixedly connected to two sliding columns.

[0010] Preferably, a double-ended screw is rotatably connected inside the mounting bracket, and the two sliders are respectively screwed onto the two ends of the double-ended screw.

[0011] Preferably, one end of the double-ended screw extends rotatably to the outside of the mounting bracket, and a handle is fixedly installed at the end of the double-ended screw that extends out of the mounting bracket.

[0012] Preferably, a rotating seat is fixedly installed at one end of the rotating rod, and a limiting frame is slidably connected inside the rotating seat. The limiting frame has an L-shaped structure, and one end of the limiting frame is slidably engaged with one side of the mounting frame. A spring is fixedly connected between the limiting frame and the rotating seat.

[0013] Preferably, a slide rod is fixedly installed on one side of the limiting frame, one end of the slide rod slides through the rotating seat, and a pull handle is fixedly installed at the end of the slide rod.

[0014] Preferably, the spring is sleeved on the outside of the slide rod.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] (1) This utility model is equipped with baffles, top plates and screws. When disassembling the bearing on the outside of the rotating shaft, the two baffles point inward and abut against one side of the bearing. The two top plates rotate and fit together, so that the ends of the two top plates abut against the end of the rotating shaft. When disassembling the bearing on the inside of the housing, the two baffles point outward and pass through the middle of the bearing, abut against one side of the bearing. The two top plates rotate and unfold so that one side of the two top plates abuts against the end of the housing. Then, by rotating the screw, the fixed plate and the movable seat drive the two top plates to move, so that the two top plates push the rotating shaft or the housing and the bearing to move relative to each other. In this way, the bearings on the outside of the rotating shaft and the inside of the housing can be disassembled. It is highly practical. The bearing can be disassembled by simply rotating the screw. The operation is simple and the efficiency is high.

[0017] (2) The present invention is provided with a threaded sleeve and a threaded cylinder. When the threaded sleeve is rotated and moves along the threaded cylinder toward the direction close to the top plate, one end of the threaded sleeve moves to the outside of the two top plates, so that the two top plates fit together. This makes the width of the two top plates smaller, so that the two top plates can pass through the middle of the bearing, which is convenient for pushing the rotating shaft to achieve relative movement with the bearing. When the threaded sleeve is rotated and moves along the threaded cylinder toward the direction away from the top plate, the threaded sleeve is not located on the outside of the two top plates. This allows the two top plates to rotate and unfold, making the width of the two top plates larger and able to abut against the edge of the outer shell, which is convenient for pushing the outer shell to achieve relative movement with the bearing.

[0018] (3) This utility model is equipped with a double-ended screw and a slider. By rotating the double-ended screw, the two sliders move relative to each other, thereby driving the two sliding columns to move relative to each other. Then, the two rotating rods drive the two baffles to move relative to each other, thereby adjusting the distance between the two baffles. This makes it possible to disassemble bearings of different sizes and specifications, increasing its practicality.

[0019] (4) This utility model is equipped with a limiting frame. The spring force makes the L-shaped limiting frame abut against one side of the mounting frame, thereby limiting the rotation of the rotating seat and thus limiting the rotation of the baffle driven by the rotating rod. This prevents the baffle from rotating during the disassembly of the bearing and ensures the reliability of the contact between the baffle and the bearing. In addition, by pulling the handle, the sliding rod can be moved to move the limiting frame, so that the limiting frame compresses the spring and retracts into the rotating seat. At this time, the rotating seat can be rotated to drive the rotating rod and the baffle to rotate, thereby adjusting the orientation of the baffle. The operation is simple and efficient.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 As shown, this utility model provides the following technical solution:

[0028] A bearing removal device for a hydraulic motor includes a mounting frame 1 and a screw 9 that screws through the mounting frame 1. A fixing plate 17 is fixedly installed at one end of the screw 9. A movable seat 6 is rotatably sleeved on the outside of the fixing plate 17. Two top plates 4 are symmetrically rotatably connected to the ends of the movable seat 6. Two sliding columns 2 are symmetrically slidably connected on both sides of the screw 9 on the mounting frame 1. Rotating rods 18 are rotatably connected inside the two sliding columns 2. Baffles 3 are fixedly installed at the ends of the two rotating rods 18.

[0029] A guide rod 8 is fixedly installed at one end of the movable base 6, and one end of the guide rod 8 slides through the mounting frame 1;

[0030] One end of the lead screw 9 has a hexagonal countersunk groove 16;

[0031] A threaded cylinder 15 is fixedly installed on the outside of the movable seat 6. A threaded sleeve 5 is screwed onto the outside of the threaded cylinder 15. One end of the threaded sleeve 5 is slidably sleeved on the outside of the two top plates 4.

[0032] Based on the above-disclosed structure, when disassembling the bearing for the hydraulic motor:

[0033] When disassembling the bearing on the outer side of the rotating shaft, first rotate the threaded sleeve 5 so that it moves along the threaded cylinder 15 towards the top plate 4, causing one end of the threaded sleeve 5 to move to the outside of the two top plates 4. This restricts the rotation and unfolding of the two rotating plates 4, causing the middle parts of the two top plates 4 to fit together, and aligning the ends of the two top plates 4 with the ends of the rotating shaft. Then, slide the two sliding pins 2 on the mounting bracket 1 so that the two sliding pins 2 respectively abut against the two ends of the outer diameter of the bearing to be disassembled. Next, rotate the two rotating rods 18 to drive the two baffles 3 to rotate, causing the two baffles 3 to move to the side of the bearing to be disassembled and abut against that side. Two top plates 4 and two baffles 3 are located on both sides of the bearing to be disassembled. Then, a manual or electric hex wrench is inserted into the hexagonal recess 16 and drives the screw 9 to rotate, causing the fixed plate 17 to move the movable seat 6 along the guide rod 8, so that the two top plates 4 approach and press against the end of the rotating shaft. Then, the screw 9 is rotated, so that the ends of the two top plates 4 push the rotating shaft to move. Since the distance between the two baffles 3 and the mounting frame 1 is fixed, the two top plates 4 push the rotating shaft away from the mounting frame 1, thereby causing the rotating shaft to move relative to the bearing to be disassembled. This process continues until the rotating shaft separates from the bearing to be disassembled, thus completing the disassembly of the bearing on the outside of the rotating shaft.

[0034] When disassembling the bearing inside the housing, first rotate the threaded sleeve 5 so that it moves away from the top plate 4 along the threaded cylinder 15, so that the end of the threaded sleeve 5 is no longer outside the two top plates 4, allowing the two rotating plates 4 to rotate and unfold to the sides, so that the two unfolded top plates 4 correspond to the edge of the housing. Then, slide the two sliding pins 2 on the mounting bracket 1 and move them towards the center so that the distance between the outermost edges of the two sliding pins 2 is equal to the inner diameter of the bearing to be disassembled. Move the mounting bracket 1 so that the two sliding pins 2 and the rotating rod 18 drive the two baffles 3 through the center of the bearing to be disassembled. Then rotate the two rotating rods 18 and the two rotating rods 18 respectively. Rod 18 drives the two baffles 3 to rotate, causing the two baffles 3 to move to the side of the bearing to be disassembled and to contact the side of the bearing to be disassembled. Then, screw 9 is rotated, causing fixed plate 17 to drive moving seat 6 to move along guide rod 8, causing the two top plates 4 to approach and press against the edge of the housing. Then screw 9 is rotated again, causing the two top plates 4 to push the housing to move. Since the distance between the two baffles 3 and the mounting frame 1 is fixed, the two top plates 4 push the housing away from the mounting frame 1, thereby causing the housing and the bearing to be disassembled to move relative to each other. This continues until the housing and the bearing to be disassembled are separated, and the bearing inside the housing is disassembled.

[0035] Regarding the movement of the two sliding rods 2, the following structure is preferably provided:

[0036] Two sliders 11 are slidably connected inside the mounting bracket 1, and the two sliders 11 are fixedly connected to two sliding columns 2 respectively.

[0037] A double-ended screw 10 is rotatably connected inside the mounting bracket 1, and two sliders 11 are respectively screwed onto the two ends of the double-ended screw 10;

[0038] One end of the double-ended screw 10 extends to the outside of the mounting bracket 1, and a handle 7 is fixedly installed on the end of the double-ended screw 10 that extends out of the mounting bracket 1.

[0039] As can be seen from the above, rotating the handle 7 drives the double-ended screw 10 to rotate, causing the two sliders 11 connected at both ends of the double-ended screw 10 to move towards the center within the mounting frame 1, thereby driving the two sliding pillars 2 to move towards the center within the mounting frame 1 respectively; conversely, rotating the handle 7 drives the double-ended screw 10 to rotate in the opposite direction, causing the two sliding pillars 2 to move to the sides within the mounting frame 1 respectively, thus making it possible to disassemble bearings of different sizes and specifications, increasing practicality.

[0040] In addition, regarding the rotation and limiting of the baffle 3, the following structure is preferably provided:

[0041] A rotating seat 13 is fixedly installed at one end of the rotating rod 18. A limit frame 14 is slidably connected inside the rotating seat 13. The limit frame 14 has an L-shaped structure. One end of the limit frame 14 is slidably engaged with one side of the mounting frame 1. A spring 20 is fixedly connected between the limit frame 14 and the rotating seat 13.

[0042] A slide rod 19 is fixedly installed on one side of the limit frame 14. One end of the slide rod 19 slides through the rotating seat 13, and a pull handle 12 is fixedly installed at the end of the slide rod 19. A spring 20 is sleeved on the outside of the slide rod 19.

[0043] As can be seen from the above, when the baffle 3 needs to be rotated, pulling the handle 12 causes the slide rod 19 to move the limiting frame 14 toward the rotating seat 13. At the same time, the limiting frame 14 and the rotating seat 13 compress the spring 20 until the limiting frame 14 is completely retracted into the rotating seat 13. At this time, the rotating seat 13 can be rotated to drive the rotating rod 18 to rotate, which in turn drives the baffle 3 to rotate. When the baffle 3 points to the middle or the outer side of the mounting frame 1, the rotating seat 13 drives the limiting frame 14 to move to the outer side of the mounting frame 1. Then, the handle 12 is released. Under the elastic force of the spring 20, the spring 20 pushes the limiting frame 14 closer to the mounting frame 1, so that one end of the limiting frame 14 abuts against one side of the mounting frame 1, thereby restricting the rotation of the rotating seat 13, and thus restricting the rotation of the rotating rod 18 and the baffle 3. This prevents the baffle 3 from rotating during the disassembly of the bearing and ensures the reliability of the contact between the baffle 3 and the bearing to be disassembled.
