[0002] The reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between the prime mover and the working machine, and is widely used in modern machinery.

[0003] A pair of wheels is usually installed on the output shaft of the reducer, and the output shaft of the reducer is connected to the input shaft of the working machine through the pair of wheels. However, after a long period of use, the shaft seal of the reducer will seep or leak oil, so the shaft seal needs to be replaced. Before replacing the shaft seal, the pair of wheels needs to be removed first. A puller is usually used to remove the pair of wheels, but the puller is easy to slip when pulling it out, which poses a safety hazard. When the pair of wheels is installed tightly, it may also make the pair of wheels unable to be pulled out. Utility Model Content

[0026] The following is combined with Figure 1 To Attachment Figure 6 And specific embodiments describe the present invention in detail.

[0027] Reference Figure 1-6 The utility model provides a pair of reducer wheel disassembly tool, which is used to disassemble the pair of wheels 11 installed on the output shaft 10 of the reducer 1. The pair of reducer wheel disassembly tool comprises a receiving box 2 with openings at the top and the bottom. A jack 20 is horizontally arranged in the receiving box 2. Two support rods 21 are fixedly connected to the bottom of the receiving box 2. The jack 20 is mounted on the two support rods 21. An annular limiting seat 22 is fixedly connected to the inner wall of the receiving box 2. The bottom of the jack 20 is clamped in the limiting seat 22, so that the jack 2 0 is limited to improve the stability of the jack 20; a clearance groove 23 is opened on the side wall of the accommodating box 2, and the operating rod of the jack 20 is movably arranged in the clearance groove 23 and one end thereof passes through the accommodating box 2, so that it is convenient for personnel to rotate the operating rod; an accommodating groove 24 is opened on the inner wall of the accommodating box 2 opposite to the limiting seat 22, and the opening of the accommodating groove 24 is arranged downward, and the pair of wheels 11 is movably arranged in the accommodating groove 24, and the end surface of the pair of wheels 11 close to the output shaft 10 abuts against the inner wall of the accommodating box 2, and the top rod of the jack 20 passes through the pair of wheels 11 and abuts against the output shaft 10.

[0028] A cover plate 3 is hinged on the top of the containing box 2, and one end of the cover plate 3 is connected to the containing box 2 through a hinge 30. A clamping block 31 is fixedly connected to the side of the cover plate 3 close to the jack 20. The clamping block 31 is pressed on the jack 20 to further improve the stability of the jack 20. The end surface of the clamping block 31 contacting the jack 20 is set as an arc surface adapted to the jack 20, thereby increasing the contact area between the clamping block 31 and the jack 20.

[0029] A locking assembly 4 for fixing the cover plate 3 is provided at one end of the cover plate 3 away from the hinge 30, and the locking assembly 4 includes two fixing plates 40, and the fixing plates 40 are fixedly connected to the outer wall of the containing box 2, and a horizontally arranged locking rod 41 is inserted between the two fixing plates 40, and a pull ring 42 is fixedly connected to the end of the locking rod 41 away from the cover plate 3, and a supporting ring 43 is also fixedly connected to the locking rod 41, and the supporting ring 43 is located between the two fixing plates 40, and a spring 44 is fixedly connected between the supporting ring 43 and the fixing plate 40 away from the cover plate 3, and the spring 44 can push the supporting ring 43 to move toward the direction of the cover plate 3; a connecting plate 45 is fixedly connected to the end of the cover plate 3 away from the hinge 30, and a locking hole 46 is opened in the connecting plate 45, and the end of the locking rod 41 away from the pull ring 42 is inserted into the locking hole 46, so as to fix the cover plate 3.

[0030] Wheels 5 are provided at the four corners of the bottom of the storage box 2 to improve the mobility of the storage box 2; a lifting assembly 6 is also provided between the storage box 2 and the wheels 5, and the lifting assembly 6 includes four racks 60, which vertically penetrate the storage box 2, and the wheels 5 are installed at the bottom ends of the racks 60. Four support frames 61 are fixedly connected to the top of the storage box 2, and each support frame 61 is rotatably connected with a gear 62, which meshes with the rack 60. A rotating shaft 63 is fixedly connected between the two gears 62 located at the same end of the storage box 2, and a crank 64 is fixedly connected to one end of the rotating shaft 63. A limit member 65 for limiting the rotation of the gear 62 is provided on the support frame 61 near the crank 64. In this embodiment, the limit member 65 is a limit plate 650, which is vertically slidably penetrated on the support frame 61, and the bottom end of the limit plate 650 is inserted between two teeth of the gear 62 to limit the rotation of the gear 62.

[0031] The lifting component 6 can adjust the overall height of the storage box 2. On the one hand, after the storage box 2 is lifted up, it is convenient for the wheels 11 to enter the storage box 2 from the bottom of the storage box 2. On the other hand, the storage box 2 can adjust its own height according to the wheels 11 of different heights, so as to adapt to various types of reducers 1; the lifting component 6 can also adjust the inclination of the storage box 2. When the rising heights of the two ends of the storage box 2 are inconsistent, the storage box 2 is in a tilted state. When the reducer 1 is in a tilted state or the output shaft 10 is damaged and bent, the storage box 2 needs to be disassembled in the tilted state for the wheels 11. Therefore, the lifting component 6 can make the storage box 2 adapt to different conditions.

[0032] The implementation principle of the reducer wheel disassembly tool provided by the utility model is: before disassembling the pair of wheels 11, first pull the limit plate 650 upwards to make the limit plate 650 disengage from the gear 62, turn the crank 64, the crank 64 drives the gear 62 to rotate through the rotating shaft 63, the gear 62 moves upward on the rack 60, the gear 62 drives the accommodating box 2 to move upward through the supporting frame 61, when the accommodating box 2 is higher than the pair of wheels 11, push the accommodating box 2 in the direction close to the reducer 1, so that the pair of wheels 11 are located in the accommodating box 2, and then turn the crank 64 in the opposite direction to move the accommodating box 2 downward, when the top rod of the jack 20 is aligned with the center hole of the pair of wheels 11, the accommodating box 2 stops descending, and the limit plate 650 is inserted downward into the gear 62, thereby limiting the rotation of the gear 62, which also fixes the height of the accommodating box 2.

[0033] Then, the operating lever of the jack 20 is repeatedly swung to gradually extend the top rod of the jack 20, which passes through the center hole of the pair of wheels 11 and presses against the output shaft 10. As the top rod of the jack 20 is extended, the jack 20 pushes the receiving box 2 to move away from the reducer 1, and the receiving box 2 pushes the pair of wheels 11 to move away from the reducer 1, thereby removing the pair of wheels 11 from the output shaft 10.

[0034] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
