The fixing assembly comprises a locking element 25, a gasket 26 and a screw gland 27, wherein the screw gland 27 is fixedly connected to the middle of the left end of the rotor set 23, the locking element 25 penetrates through the middle of the screw gland 27 and is fixedly connected to the left end of the cone shaft 22, and the gasket 26 is abutted between the locking element 25 and the screw gland 27.

Wherein the locking element 25 is a socket head cap screw; the screw gland 27 is provided with external threads and a second threaded hole 271 and a through hole 272 which are axially arranged; the external thread is provided on the outer diameter of the screw gland 27; the second screw hole 271 is provided in the middle of the screw gland 27, and the through hole 272 is provided in plurality and provided around the second screw hole 271.

The middle part of the left end of the conical shaft 22 is provided with a first threaded hole 221, the locking element 25 passes through the second threaded hole 271 of the screw gland 27 in a threaded manner, and is then connected in the first threaded hole 221 in a threaded manner in the process of rotation locking; wherein the first screw hole 221 and the second screw hole 271 are on the same horizontal line.

The disassembly tool comprises three independent components, namely a disassembly screw 11, a T-shaped block 12 and a disassembly adapter 13. Wherein the disassembly screw 11 is an inner hexagon bolt; ding Zikuai 12 includes a circular plate 121 and a cylindrical rod 122, and the cylindrical rod 122 is fixedly disposed at a side middle portion of the circular plate 121.

Since the compressor and the rotor set 23 are of various kinds, the diameter of the circular plate 121 is required to be directly smaller than that of the conical shaft 22, the length of the cylindrical rod 122 is smaller than the depth of the first threaded hole 221, and the diameter of the first threaded hole 221 is set to be larger than that of the cylindrical rod 122, so that the overall structure of the conical shaft 22 can be maintained from being damaged in the disassembling process.

Then, the pneumatic wrench is used to drive the disassembly screw 11 to axially rotate rightward, and the left end of the t-block 12 is axially pressed, so that the rotor set 23 is forced to axially move toward the left side of the taper shaft 22. The rotor set 23 will gradually disengage from the cone shaft 22 under force until completely disengaged.

After the rotor set 23 is removed, the removal screw 11 and the screw gland 27 are removed from the rotor set 23, and Ding Zikuai is easily removed from the first threaded bore 221 without an abutting force.
