[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1As shown, a vertical bearing bushing removal tool comprises a mechanism disk 1, the inner side of the mechanism disk 1 is rotatably connected with an adjusting mechanism 2, a push rod 3 is threadedly connected at the inner center of the mechanism disk 1, an inner hexagonal hole 4 is provided at the upper end axis of the push rod 3, two mounting mechanisms 5 symmetrically distributed on the left and right are movably sleeved on the inner side of the adjusting mechanism 2, and two limiting grooves symmetrically distributed on the left and right are provided on the upper surface of the mechanism disk 1.

[0027] It should be noted that the limiting groove 6 is used to limit the movement range of the installation mechanism 5, and the hexagonal hole 4 provides more ways to rotate the top rod 3. The top rod 3 can be rotated using a hexagonal screwdriver.

[0028] like Figure 2 , Figure 3 As shown, the adjusting mechanism 2 includes a bevel gear ring 21, the outer wall of the bevel gear ring 21 is rotatably connected to the upper wall of the mechanism disk 1 near the edge, and a transmission rod 22 is rotatably connected to the lower surface of the inner cavity of the mechanism disk 1 near the bosses on the front and rear sides, and the front and rear ends of the two transmission rods 22 are fixedly connected to the first bevel gears 23, and the upper sides of the two first bevel gears 23 located on the outermost sides are meshed and connected with the front and rear sides of the bevel gear ring 21, and the lower surface of the inner cavity of the mechanism disk 1 is rotatably connected to the bosses on the left and right sides. Two lead screws 24 symmetrically distributed front and back are fixedly connected, and the outer walls of the two lead screws 24 are fixedly connected near the middle part with second bevel gears 25, and the rear side of the second bevel gear 25 that is away from each other is meshed and connected with the left side of the first bevel gear 23 located on the inner side.

[0029] It should be noted that rotating the bevel gear ring 21 can drive the first bevel gear 23 located on the outside to rotate. When the first bevel gear 23 located on the outside rotates, the transmission rod 22 drives the first bevel gear 23 located on the inside to rotate. When the first bevel gear 23 located on the inside rotates, it drives the two second bevel gears 25 to rotate synchronously, thereby causing the two screw rods 24 to rotate synchronously.

[0030] like Figure 3 As shown, the outer wall of the screw rod 24 is threadedly connected with two sliders 26 which are symmetrically distributed on the left and right.

[0031] It should be noted that the screw rod 24 is a bidirectional screw rod having two threads in opposite directions, and the two sliders 26 are respectively threadedly connected to the threads in different directions, so that when the screw rod 24 rotates, the two sliders 26 move synchronously in opposite directions.

[0032] like Figure 2 , Figure 3 As shown, the upper surface of the bevel gear ring 21 is fixedly connected with a circular ring via a column.

[0033] It should be noted that the circular ring is used to facilitate the user to apply force to the bevel gear ring 21 when rotating the bevel gear ring 21 .

[0034] like Figure 2 , Figure 4 As shown, the two mounting mechanisms 5 both include an adjusting rod 51 , the outer wall of the adjusting rod 51 is movably sleeved on the inner side of the slider 26 , and the lower end of the adjusting rod 51 is fixedly connected with a connecting screw 52 .

[0035] It should be noted that the thread of the connecting screw 52 is connected to the threaded hole on the bearing bushing, so that the disassembly tool is fixed on the bushing.

[0036] like Figure 4 , Figure 5 As shown, the outer wall of the adjusting rod 51 is movably sleeved with two fixed components 53 distributed up and down, and the fixed components 53 are located on the upper and lower sides of the mechanism disk 1, and the two fixed components 53 each include an adjusting sleeve 531, the inner side of the adjusting sleeve 531 is movably sleeved on the outer side of the adjusting rod 51, the outer wall of the adjusting rod 51 has a plurality of linearly evenly distributed L-shaped fixed grooves 54, and the plurality of L-shaped fixed grooves 54 are distributed in two groups in a ring shape on the outer wall of the adjusting rod 51, the outer wall of the adjusting rod 51 is provided with two movable grooves 55 distributed symmetrically on the left and right, and the movable grooves 55 connect the horizontal ends of the L-shaped fixed grooves 54, the inner side of the adjusting sleeve 531 is fixedly connected with two evenly distributed limit blocks 532, and the outer side of the limit blocks 532 is slidably connected to the inner side of the movable groove 55.

[0037] It should be noted that when the limit block 532 is located on the inner side of the movable groove 55, the adjusting sleeve 531 can move quickly on the adjusting rod 51, and the adjusting sleeve 531 is rotated so that the limit block 532 moves to the inner side of one of the L-shaped fixed grooves 54, so that the adjusting sleeve 531 is fixed on the outer side of the adjusting rod 51, so that the adjusting sleeve 531 cannot move up and down.

[0038] like Figure 5 As shown, the outer wall of the adjusting sleeve 531 is threadedly connected to the limiting nut 533 .

[0039] It should be noted that by rotating the limit nut 533, the limit nut 533 can be moved up and down. The limit nut 533 is used to provide a movement margin for the adjustment sleeve 531 to compensate for the distance between two adjacent upper and lower L-shaped fixing grooves 54, so that the mechanism disk 1 is fixed more tightly.

[0040] like Figure 2 As shown, a circular plate is fixedly connected to the lower end of the push rod 3.

[0041] It should be noted that the circular plate is used to increase the contact area between the push rod 3 and the bearing, thereby reducing the wear of the push rod 3 on the bearing during the disassembly operation.

[0042] The working principle of the utility model is as follows: first, rotating the bevel gear ring 21 can drive the first bevel gear 23 located on the outside to rotate. When the first bevel gear 23 located on the outside rotates, the transmission rod 22 drives the first bevel gear 23 located on the inside to rotate. When the first bevel gear 23 located on the inside rotates, it drives the two second bevel gears 25 to rotate synchronously, thereby making the two screw rods 24 rotate synchronously. The screw rod 24 is a bidirectional screw rod, which contains two threads in opposite directions. The two sliders 26 are respectively threadedly connected with threads in different directions, so that when the screw rod 24 rotates, the two sliders 26 perform synchronous reverse movement. By rotating the bevel gear ring 21, the two screw rods 24 rotate synchronously, causing the two sliders 26 to perform synchronous reverse movement laterally, so that the movement amount of the two mounting mechanisms 5 is consistent, and the distance between each mounting mechanism 5 and the push rod 3 is consistent. When performing the disassembly operation, the lower end of the push rod 3 can be aligned with the middle of the bearing, which is convenient for disassembly. Finally, the threaded connection of the connecting screw 52 The cam 532 is then moved to the inner side of the movable groove 55 so that the adjusting sleeve 531 can be quickly moved on the adjusting rod 51. The adjusting sleeve 531 is rotated so that the cam 532 moves to the inner side of one of the L-shaped fixing grooves 54, so that the adjusting sleeve 531 is fixed to the outer side of the adjusting rod 51, so that the adjusting sleeve 531 cannot move up and down. The cam 533 is rotated so that the cam 533 can move up and down. The cam 533 is used to provide a movement margin for the adjusting sleeve 531 to compensate for the distance between the upper and lower adjacent L-shaped fixing grooves 54, so that the mechanism disk 1 is fixed more tightly. By threading the outer wall of the connecting screw 52 into the screw hole of the bearing bushing, the cam 532 is moved to the inner side of the movable groove 55, so that the adjusting sleeve 531 can be quickly moved, which makes it more convenient to fix the mechanism disk 1, reduces the time consumed by installing the cam 533, and is convenient to operate.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
