Description

Technical Field

[0001] The utility model relates to the technical field of fan disassembly, in particular to a fan gear disassembly device. Background Art

[0002] Generally, the maintenance and repair of a fan require the removal of the gear 02. As Figure 1 shown, since the gear 02 of the fan is arranged close to the fan housing 01, the gap between the gear 02 and the fan housing 01 is small. The traditional puller tool cannot enter between the gear 02 and the fan housing 01, making it difficult to disassemble the gear 02 for maintenance and repair. In the absence of a suitable tool, only destructive demolition can be carried out, resulting in higher maintenance and repair costs. In addition, when using the destructive demolition method, it is also necessary to protect the gear 02 from damage, resulting in a longer maintenance time and lower efficiency.

[0003] In response to this problem, the existing patent No. 202322626816.2 discloses a gear shaft end disassembly device for a drum-shaped tooth coupling. First, a suitable connecting screw is selected according to the gear shaft end, and the connecting screw is threadedly connected to the gear shaft end. Then, the connecting optical rod is connected to the traction screw. Then, the position of the traction screw is adjusted by sliding the adjustment block according to the position of the traction pull head, so that the traction pull head is connected to the traction screw. Furthermore, the traction screw is fixedly installed on the gear shaft end through the traction pull head. Finally, the top plate is moved. When the output shaft of the jack abuts against the tooth shaft, the locking nut is rotated so that the bottom of the locking nut abuts against the top of the abutting plate, and then the jack is made to abut between the top plate and the tooth shaft. The jack is activated to push the tooth shaft, so that the tooth shaft is disassembled from the gear shaft end. The effect of disassembling and adapting to different specifications of drum-shaped tooth couplings and jacks is achieved, which is convenient for disassembling the gear shaft ends of different specifications of tooth couplings and expanding the applicable range of the disassembly tool.

[0004] The solution of this patent disassembles the tooth shaft 03 and the gear 02 by the output shaft of the jack abutting against the tooth shaft 03 and the connecting screw being threadedly connected to the threaded hole 04. It is applicable to the situation where the end of the gear 02 has a fixed position, such as the threaded hole 04. However, in the face of a damaged threaded hole 04, or a different position setting method of the threaded hole 04, or a gear 02 without a threaded hole 04, it is still difficult to disassemble, and the compatibility is poor. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a fan gear disassembly device, which uses a suction cup to adsorb on the gear end, drives the micro vacuum pump to work to evacuate the suction cup to further adsorb the gear end, is more convenient for disassembly, has a more firm fixation, and has stronger compatibility, and is applicable to the situation where the gear end has no fixed position.

[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows: A fan gear disassembly device includes a top plate and a bottom plate horizontally arranged in sequence from top to bottom. A plurality of suction cups are evenly arranged at the bottom edge of the bottom plate. A micro vacuum pump is provided on the top plate. The micro vacuum pump is communicated with the suction cups through a hose. The micro vacuum pump is used to evacuate the suction cups to adsorb the gear end; A top column for fixing the gear shaft is vertically arranged in the center between the top plate and the bottom plate. A rotary extension cylinder is provided in the center of the top plate. The output end of the rotary extension cylinder is fixedly connected to the tail end of the top column. A through hole allowing the top column to pass through is provided in the center of the bottom plate.

[0007] Preferably, a handle is provided on the top plate.

[0008] Preferably, threads matching the internal threads of the gear are provided on the outer wall of the top column near the head end.

[0009] Preferably, a gasket is detachably provided at the bottom center of the top plate. A through groove matching the position of the gasket is provided on the top plate. The through groove is used for a bolt to pass through to fasten the gasket to the gear end.

[0010] The beneficial effects of the present utility model are as follows:

[0011] In this solution, the suction cups are used to adsorb the gear end. Driving the micro vacuum pump to work evacuates the suction cups to further adsorb the gear end. Compared with the connection method of the connecting screw and the threaded hole in the existing patent, the disassembly is more convenient, the fixation is more firm, and the compatibility is stronger, which is suitable for the situation where there is no fixed position at the gear end.

[0012] In this solution, a bolt is used to fasten the gasket to the gear end through the through groove, ensuring that the disassembly device is firmly fixed to the gear end, further improving the firmness of the fixation, and is also suitable for the situation where there is no fixed position at the gear end.
