[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 to Figure 2The utility model provides a disassembly tool for a helical axis motor rotor assembly, comprising a helical axis rotor assembly and a disassembly assembly.

[0021] The helical axis rotor assembly includes an output shaft 5, a housing 6, and a rotor 9. A threaded countersunk hole is provided at the upper end of the output shaft 5. The output shaft 5 and the rotor 9 are movably connected through a center rod 8 and a piston 7. The housing 6 includes a vertical section and an inclined section. A flange is provided on the outer wall of the upper port of the vertical section. The flange is provided with four evenly distributed flange holes. An oil separator is provided at the lower port of the inclined section. The output shaft 5 and the rotor 9 are arranged in the housing. The rotor 9 is located in the inclined section. The rotor 9 sits on the oil separator. The output shaft 5 is located in the vertical section. The output shaft 5 is connected to the housing 6 through a tapered roller bearing group 10.

[0022] The disassembly assembly includes a support plate 1, a nut 2, a pull rod 3, and a support rod 4. The support plate 1 is provided with fixing holes corresponding to two diagonal flange holes. A center hole is provided in the center of the support plate 1. An upper threaded section is provided on the outer wall of the upper end of the pull rod 3, and the upper threaded section can be connected to the nut 2. A supporting portion is provided at the upper end of the pull rod 3. A lower threaded joint is provided at the lower end of the pull rod 3, and the threaded joint can be connected to the threaded countersunk hole. The pull rod 3 can pass through the center hole. Two support rods 4 are provided, and plug rods are provided at both ends of the support rod 4, and the plug rods can be plugged into flange holes or fixing holes.

[0023] Among them, at least three pistons 7 are arranged, the center rod 8, piston 7 and rotor 9 are slidably plugged, the center rod 8, piston 7 and output shaft 5 are connected by a ball joint, and an oil hole connected to the cavity where the piston 7 is located is arranged at the bottom of the rotor 9. The oil dividing ring enables the piston 7 to reciprocate in oil intake and discharge oil, thereby causing the rotor to rotate. A balancing hole connected to the cavity where the center rod 8 is located is arranged at the bottom of the rotor 9, so that the center rod 8 can move.

[0024] Among them, the support plate 1 and the support rod 4 are made of medium carbon steel after quenching and tempering to increase the surface hardness of the parts. The nut 2 and the pull rod 3 are made of medium carbon alloy structural steel after quenching and tempering, and have high static strength and high fatigue limit, and strong resistance to high loads.

[0025] Among them, the insertion rod and the flange hole, the insertion rod and the fixing hole are all clearance fit. The clearance is large and can be easily inserted. The pull rod 3 and the output shaft 5 are threaded. When assembling, the threaded joint at the bottom of the pull rod 3 needs to be tightened. The nut 2 and the pull rod 3 are threaded. The tapered roller bearing group 10 and the housing 6 are interference fit.

[0026] When in use, the lower ends of the two support rods 4 are inserted into the diagonal flange holes of the shell 6, and the upper ends of the two support rods 4 are inserted into the fixing holes of the support plate 1. The pull rod 3 passes through the center hole of the support plate 1 and is connected to the threaded countersunk hole of the output shaft 5. The nut 2 is screwed into the upper threaded section of the pull rod 3 to fit the support plate 1.

[0027] At this time, the disassembly assembly has been fixed. Use an open-end wrench to fix the supporting part of the pull rod 3 to prevent it from rotating. Turn the nut 2 clockwise. Since the support plate 1, support rod 4, and housing 6 are fixed in position, the nut 2 rotates the pull rod 3 to rise. The pull rod 3 pulls the output shaft 5 to rise. Continue to rotate until the output shaft 5 is separated from the housing 6, and the output shaft 5, tapered roller bearing group 10, center rod 8, piston 7, and rotor 9 are taken out.
