[0033] See attached Figure 1 and 2 , Embodiment 1 provides a hollow shaft locking disk reducer disassembly and assembly tool, including a reducer disassembly tool and a reducer installation tool:

[0034] The reducer disassembly tool comprises a support 1, a screw rod 2, a protective cap 6 and a force rod 7. The support 1 is a cylindrical structure with front and rear openings.

The protective cap 6 is pressed against the bolt hole at the end of the equipment transmission shaft 14 located in the hollow shaft 13 of the reducer. The screw rod 2 is rotated by the force rod 7. The screw rod 2 drives the protective cap 6 to move axially backward to push the equipment transmission shaft 14 out of the reducer, thereby completing the disassembly of the reducer;

[0035] The reducer installation tool comprises a support 1, a screw 2, a pressure bearing 3, an adjustment pad 5, a protective cap 6, a force rod 7 and a locking nut 11; the screw 2 is threadedly connected to the support 1, and the other end of the screw 2 with an external thread passes through the hollow shaft 13 of the reducer and is threadedly connected to the end bolt hole of the equipment transmission shaft 14, and is locked by the locking nut 11, so that the screw 2 and the equipment transmission shaft 14 become one; the force rod 7 is installed on the force rod seat 9 on the outer wall of the support 1, and the screw 2 in the support 1 is provided with a front and rear arrangement Adjust the pad 5 and the pressure bearing 3. The end of the hollow shaft 13 of the reducer is located inside the rear side of the support 1 and contacts with the pressure bearing 3. The adjusting pad 5 is used to adjust the distance between the support 1 and the front shaft side cover 12 of the reducer so that a gap is left between the support 1 and the front shaft side cover 12 of the reducer. The support 1 is rotated by the force rod 7. The rotation of the support 1 drives the screw 2 to move forward axially. The screw 2 drives the equipment transmission shaft 14 to enter the hollow shaft 13 of the reducer, so that the hollow shaft 13 of the reducer is sleeved on the equipment transmission shaft 14 to complete the installation of the reducer.

[0036] In the first embodiment, the assembly and disassembly of the reducer requires the use of the support 1, the screw 2, the pressure bearing 3, the adjustment pad 5, the protective cap 6, the force rod 7, the force rod seat 9 and the locking nut 11 in the combined tool.

[0037] See attached Figure 5 and 12 Four force rod seats 9 are evenly arranged along the circumference on the outer wall of the support 1. When the reducer is installed, a force rod 7 is inserted into each force rod seat 9, and the force rod 7 is used to implement the rotation of the support 1.

[0038] See attached Figure 7 and 12 One end of the screw rod 2 is provided with a force rod hole 8. When the reducer is disassembled, the force rod 7 is inserted into the force rod hole 8, and the force rod 7 is used to implement the rotation of the screw rod 2.

[0039] See attached Figure 1 and 6 One end of the support 1 is prefabricated with 8 bolt connection holes 10, which is convenient for connecting with the front shaft side cover 12 of the reducer when disassembling the reducer. The other end of the support 1 is processed with a trapezoidal internal thread. With the help of the support force of the reducer and the ejection force provided by the screw rod 2 by the thread, the drive shaft 14 of the ejector is ejected and the reducer is disassembled.

[0040] See attached Figure 1 and 9, a hemispherical groove is provided on one side of the ejector block 4 adjacent to the protective cap 6, one end of the protective cap 6 is hemispherical and matches the hemispherical groove, and a socket is provided on the other end of the protective cap 6. When disassembling the reducer, the protective cap 6 is sleeved on the external thread at the other end of the screw 2, and the hemispherical end of the protective cap 6 is pressed against the end bolt hole of the equipment transmission shaft to prevent the tool ejection force from damaging the external thread at the other end of the screw 2 and the bolt hole at the end of the equipment transmission shaft. The end bolt hole of the equipment transmission shaft 14 is located at its axial position, and the protective cap 6 on the other end of the screw 2 is also located at its axial position, so that the ejection force is coaxial with the axis.

During assembly, the rear part of the support 1 is sleeved on the exposed end of the hollow shaft 13 of the reducer, and is rotatably arranged on the hollow shaft 13 of the reducer with the help of the adjusting pad 5 and the pressure bearing 3. The arrangement of the pressure bearing 3 enables the support 1 to easily roll on the hollow shaft 13 of the reducer. With the help of the tension generated by the rotation of the support 1, the screw rod 2 drives the equipment transmission shaft 14 into the hollow shaft 13 of the reducer, so that the reducer can be smoothly assembled on the equipment transmission shaft 14.

[0042] See attached Figure 2 and 10 The adjusting pad 5 is used when installing the reducer. The adjusting pad 5 is annular, and the inner diameter of the adjusting pad 5 is slightly larger than the outer diameter of the screw 2. By increasing or decreasing the number of adjusting pads 5, the distance between the support 1 and the reducer front shaft side cover 12 is adjusted, so that there is a gap of about 5-10mm between the reducer front shaft side cover 12, which facilitates the rotation of the support 1 and avoids friction with the reducer front shaft side cover 12. At the same time, the adjusting pad 5 prevents the pressure bearing 3 from axial displacement and positions the pressure bearing 3.

[0047] In the second embodiment, the disassembly and assembly of the reducer requires the use of the support 1, the screw rod 2, the top block 4, the protective cap 6 and the force rod 7 in the combined tool.

[0048] See attached Figure 3 and 6 One end of the support 1 is prefabricated with 8 bolt connection holes 10, which is convenient for connecting with the front shaft side cover 12 of the reducer when the hollow shaft is disassembled. The other end of the support 1 is processed with a trapezoidal internal thread. With the help of the support force of the reducer and the ejection force provided by the screw rod 2 by the thread, the purpose of ejecting the hollow shaft of the reducer to be removed is achieved.

[0049] See attached Figure 4 and 6 One end of the support 1 is prefabricated with 8 bolt connection holes 10, which is convenient for connecting with the rear shaft side cover 15 of the reducer when the hollow shaft is disassembled. The other end of the support 1 is processed with a trapezoidal internal thread. With the help of the support force of the reducer and the traction force provided by the screw rod 2 by the thread, the purpose of pulling in the hollow shaft of the reducer to be installed is achieved.
