Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly equipment, in particular to a synchronous gear disassembly tool. Background Art

[0002] In the process of gear disassembly, the gears are generally disassembled by manual hammering; however, when the gears are large in size, heavy in weight and the gear meshing clearance is small, manual hammering is more difficult; in addition, when encountering synchronous gears, the large and small gears in the synchronous gears are helical gears. In addition to the synchronous movement, the synchronous gears need to rotate during the movement (such as the synchronous gears in the large screw compressors of oil refining equipment). Therefore, manual hammering requires manual rotation of the gears while completing the hammering of the two gears, which results in low disassembly quality and is easy to cause harm to the operator.

DETAILED DESCRIPTION

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0018] Example: Please refer to Figure 1A synchronous gear disassembly tool comprises a plurality of screw rods 10 threadedly connected to two gears 1, two limit plates 11 threadedly connected to the screw rods 10, and a hydraulic cylinder 2 fixed to the middle of the limit plate 11, the output rod end of the hydraulic cylinder 2 is in close contact with the end of the gear shaft, each limit plate 11 is aligned with a gear 1, and the limit plate 11 is rotatably connected to the connecting block 9, wherein each gear 1 is threadedly connected to three screw rods 10. When it is necessary to disassemble two gears 1 at the same time, it is only necessary to screw the screw rod 10 into the end of the gear 1 and align the end of the output end of the hydraulic cylinder 2 with the gear shaft, and then start the hydraulic cylinder 2 to realize the two gears 1 being pulled out from the gear shaft. During this process, the limit plate 11 can be rotated to ensure that the gear 1 can rotate during the process of entering and exiting, and there is no need to directly touch the gear 1 with hands. Therefore, the utility model replaces the method of manually hammering the gear 1, and the two gears 1 are pushed out synchronously by two hydraulic cylinders 2, thereby improving the disassembly quality; and in the process of dismantling the gear 1, the gear 1 can also be rotated by rotating the limit plate 11. During the rotation of the gear 1, the gear shaft will also rotate, and then rotate together with the hydraulic cylinder 2, so that the hydraulic cylinder can realize the rotation of the gear 1 while pushing it out; thereby satisfying the disassembly of the synchronous gear 1 (helical gear) while protecting the health of the operator.

[0019] In this embodiment, a screw sleeve 4 is provided on the limit plate 11, and the screw sleeve 4 is threadedly connected to the screw rod 10, thereby improving the connection quality between the screw rod 10 and the limit plate 11; and each gear 1 is provided with an internal threaded hole of the same depth, and the screw rod 10 is threadedly connected to the internal threaded hole. When the six screw rods 10 are screwed into the bottom of the threaded hole, the limit plate 11 and the end face of the gear 1 are in a parallel state, thereby ensuring the stability of the hydraulic cylinder 2 when it is pushed out; the utility model also includes a mobile frame 16, and the hydraulic cylinder 2 is provided with a fixing ear, and the top of the mobile frame 16 is provided with a fixing ear. There is a connecting rod 15, on which a positioning column 14 is fixed, and the positioning column 14 is connected to the fixed ear through a wire rope 13. The bottom of the mobile frame 16 is provided with a universal roller with a brake, so as to prevent the gear 1 from falling off the gear shaft after being pushed out, and when the gear 1 is pushed out, the mobile frame 16 can be moved to realize the transfer of the gear 1; and a detachable counterweight frame 7 is provided on the side wall of the connecting block 9 away from the limiting plate 11, and a counterweight block 8 is placed on the counterweight frame 7, and a limiting column is provided on the side wall of the counterweight frame 7, and a fixed platform 6 is provided on the connecting block 9. The inner hole clearance of the column and the fixed platform 6 is matched; different counterweight blocks 8 can be prevented according to the different masses of the synchronous gear 1, so as to ensure that the gear 1 will not fall suddenly after being pushed out and hit other parts, causing damage to the gear 1; and the support foot 3 of the mobile frame 16 adopts a telescopic structure, which can be realized by threaded connection between a screw and a stud or by connecting two telescopic rods through a V-shaped spring piece, so as to adjust the height of the hydraulic cylinder 2, and then realize the disassembly of gears 1 of different heights; and each limit plate 11 is provided with A stud 12 is provided on the connecting block 9 with a connecting column 5 threadedly connected to the stud 12. Gaps are provided between the bottom of the stud 12 and the connecting column 5 and between the end of the stud 12 and the inner bottom of the connecting column 5. The threads of the two studs 12 have opposite rotation directions, which ensures the normal rotation of the two limit plates 11. The gap realizes the rotational connection between the limit plate 11 and the connecting block 9, eliminates the problem that when the rotational connection adopts a bearing connection, the counterweight block 8 will generate a large torque during the pushing process, which makes the bearing easily damaged, thereby ensuring the service life of the tooling.

[0020] How it works

[0021] When it is necessary to disassemble the two gears 1 at the same time, it is only necessary to screw the screw 10 into the end of the gear 1 and align the end of the output end of the hydraulic cylinder 2 with the gear shaft, and then start the hydraulic cylinder 2 to push the two gears 1 out from the gear shaft. During this process, the limit plate 11 can be rotated to ensure that the gears 1 can rotate during the process of entering and exiting. Therefore, the present invention replaces the method of manually hammering the gears 1 by simultaneously pushing out the two gears 1 with the hydraulic cylinder 2, thereby improving the disassembly quality; and during the disassembly of the gear 1, the gear 1 can also be rotated by rotating the limit plate 11, eliminating the operation of directly touching the gear 1 by hand, satisfying the disassembly of the synchronous gear 1 (helical gear) while protecting the health of the operator.
