Description

Technical Field

[0001] This utility model relates to the field of gear disassembly tooling technology, and in particular to a disassembly tooling for tapered gears. Background Technology

[0002] A planetary gearbox is a transmission device based on a planetary gear train structure. It achieves a reduced transmission ratio and amplified torque through the meshing of a sun gear, planet gears, and an internal ring gear. Disassembly of the gearbox output shaft is crucial in wind power maintenance and industrial equipment upkeep because, as a core component of the transmission system, the efficiency and quality of its disassembly directly impact equipment maintenance costs and downtime.

[0003] Traditional disassembly methods require multiple people working together. One person operates a large counter-pressure disassembly device, another operates high and low pressure supply equipment, and a third operates a forklift to catch the gear. This not only wastes manpower but also forklifts and other equipment. Work efficiency is low, and due to the lack of protective tooling such as baffles and fixing plates, there is a certain degree of risk during the disassembly of large gears. A single output shaft disassembly can take ≥4 hours, and balance depends heavily on the operator's experience. Furthermore, some existing tooling (such as L-shaped lifting balance frames) requires custom-made fixing plates based on the bolt holes at the shaft end, resulting in insufficient versatility.

[0004] Therefore, designing a set of tooling for gear disassembly has become one of the urgent problems to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to provide a tooling for disassembling tapered gears.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A tapered gear disassembly fixture includes a first baffle, a second baffle, a fixing plate, a lifting device, a disassembly cylinder, and a conversion connector. The first baffle includes an integrally formed first baffle handle end and a first baffle insertion end. The second baffle includes an integrally formed connecting plate and a second baffle insertion end.

[0008] The fixed plate has a rectangular cross-section and first through holes at both ends; the lifting device is cylindrical and has multiple second through holes penetrating both ends; the outer wall of the disassembly cylinder has multiple lifting holes; the conversion connector includes a conversion head adapted to the high-pressure pipe connector, and one end of the conversion head has an integrally formed connecting pipe.

[0009] The first baffle insertion end is C-shaped, and the first baffle handle end is connected to the middle of the first baffle insertion end.

[0010] The second baffle insertion end is C-shaped, one end of the connecting plate is connected to the middle of the second baffle insertion end, the other end of the connecting plate is connected to the lower part of the inner surface of the upright plate, and a handle is connected to the middle of the outer surface of the upright plate.

[0011] The upper two sides of the upright plate are provided with through holes.

[0012] The number of the second through holes is three, and they are evenly distributed along the circumference.

[0013] The disassembly cylinder has multiple through holes at one end along the circumferential direction.

[0014] During gear disassembly, the disassembly cylinder is inserted into the output shaft wheel side, the lifting device is connected to the output shaft motor side, the connecting pipe of the conversion connector is fixed to the large gear, the hydraulic cylinder is connected to the disassembly cylinder, the high-pressure pipe connector is connected to the conversion head of the conversion connector, the second baffle is inserted between the gearbox body and the large gear, and the second baffle is fixed together with the gearbox body, the first baffle is inserted between the second baffle and the large gear, the first baffle and the second baffle are interference fit, and the fixing plate is fixed to the gearbox body by bolts.

[0015] Compared with the prior art, the outstanding advantages of this utility model are:

[0016] This utility model's tapered gear disassembly fixture enables single-person disassembly, reducing the need for additional auxiliary equipment while minimizing personnel requirements. Compared to traditional tapered gear disassembly fixtures, it is not only less expensive but also allows for the simultaneous disassembly of multiple stations and gears, improving efficiency and reducing potential risks to personnel during the disassembly process.

[0017] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates the tapered gear disassembly fixture of this utility model. Attached Figure Description

[0029] like Figure 3-7 As shown, a disassembly fixture for tapered gears includes a first baffle 1, a second baffle 2, a fixing plate 3, a lifting device 4, a disassembly cylinder 5, and a conversion connector 6. Figure 1 As shown, the first baffle 1 includes an integrally formed first baffle handle end 11 and a first baffle insertion end 12, as... Figure 2 As shown, the second baffle 2 includes an integrally formed connecting plate 21 and a second baffle insertion end 22. (As indicated...) Figure 3 As shown, the cross-section of the fixing plate 3 is rectangular, and first through holes 31 are provided at both ends of the plate. Bolts can be passed through the through holes to fix the gearbox.

[0030] like Figure 4 As shown, the lifting device 4 is cylindrical, and multiple second through holes 41 extending through both ends of the lifting device 4 are provided on the lifting device 4; as Figure 5 As shown, the outer wall of the disassembly cylinder 5 is provided with multiple lifting holes 51; as Figure 6 As shown, the adapter 6 includes an adapter that is adapted to the high-pressure pipe connector, and one end of the adapter is provided with an integrally formed connecting pipe 61.

[0031] like Figure 1 As shown, the first baffle insertion end 12 is C-shaped, and the first baffle handle end 11 is connected to the middle of the first baffle insertion end 12.

[0032] like Figure 2As shown, the second baffle insertion end 22 is C-shaped. One end of the connecting plate 21 is connected to the middle of the second baffle insertion end 22, and the other end of the connecting plate 21 is connected to the lower part of the inner surface of the upright plate 23. A handle 24 is connected to the middle of the outer surface of the upright plate 23.

[0033] The upper sides of the upright plate 23 have through holes to fix the second baffle to the gearbox body. There are three second through holes 41, evenly distributed around the circumference, through which bolts can be inserted to fix the lifting device 4 to the output shaft motor side 8. One end of the disassembly cylinder 5 has multiple through holes around the circumference, through which bolts can be passed to connect to the output shaft wheel side.

[0034] like Figure 7-9 As shown, when disassembling the gear, the lifting ring is installed on the lifting hole 51 of the disassembly cylinder 5, the disassembly cylinder 5 is inserted into the output shaft wheel side, the lifting device 4 is connected to the output shaft motor side 8, and the overhead crane is operated to lift the gearbox with the output wheel side facing upward. The connecting pipe 61 of the conversion connector 6 is fixed to the large gear, the hydraulic cylinder 9 is connected to the disassembly cylinder 5, and the high-pressure pipe connector 10 is connected to the conversion head of the conversion connector 6. The second baffle 2 is inserted between the gearbox body and the large gear, and the second baffle 2 is fixed to the gearbox body with bolts. The first baffle 1 is inserted between the second baffle 2 and the large gear. The first baffle 1 and the second baffle 2 are interference fit, and the two fixing plates 3 are fixed to the gearbox body with bolts.

[0035] Then, connect the low-pressure pipe of the pressure carriage to the hydraulic cylinder 9, and connect the high-pressure pipe to the conversion head of the conversion head of the conversion head of the conversion head of the conversion head of the conversion head of the conversion head of the pressure carriage through the high-pressure pipe connector 10. Adjust the maximum expansion pressure of 1650 bar applied by the pressure carriage. The high-pressure oil expands the large gear through the high-pressure pipe connector 10 and the conversion head of the conversion head 6. When the high pressure is applied, it is found that glycerin overflows from between the large gear and the output shaft. Slowly apply low pressure to push out the output shaft, thereby achieving the purpose of disassembling the large gear. During the disassembly process, the large gear is fixed in the housing by the first baffle and the second baffle and remains stationary. Finally, operate the crane to remove the output shaft.
