Description

Technical Field

[0001] The utility model relates to the technical field of gear box sealing, in particular to a high sealing structure of a gear box. Background Art

[0002] The high-sealing structure of a gearbox usually refers to a well-designed gearbox, which aims to prevent the leakage of lubricating oil or other lubricating substances and prevent external contaminants from entering the interior of the gearbox. This high-sealing structure usually adopts multiple sealing devices, such as sealing rings, sealing gaskets, etc., to ensure that the lubrication system inside the gearbox is not disturbed by the external environment. This design can provide longer service life and more reliable performance in harsh environments, such as in environments with high temperature, high humidity, corrosive substances or more particulate matter.

[0003] The existing patent (publication number: CN214743193U) proposes a high-sealing structure for a gearbox. The utility model welds a steel ring around the axle above the axle hole of the gearbox cover, and then clamps an oil baffle plate on the steel ring. In this way, the oil on the gear and the oil splashed on the upper part during operation will not fall on the axle, and will not leak from the axle hole along the axle. At the same time, two steel rings and oil baffle plates are provided, so that the oil splashed between the gear and the axle flows evenly through the oil baffle plates on both sides to the bottom of both sides to prevent oil leakage.

[0004] However, the existing complex sealing structure makes maintenance and replacement of parts difficult, increasing maintenance costs and downtime. The complex sealing structure has high requirements for assembly accuracy, and the overall sealing effect will be affected if you are not careful. The sealing components will wear out during long-term operation, affecting the sealing effect, especially under high-speed operation conditions. Therefore, the utility model proposes a gear box high sealing structure to solve the above problems. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a gearbox high sealing structure, comprising a gearbox body, a sealing assembly is arranged on the gearbox body, and a fixing assembly is arranged on the sealing assembly;

[0007] The sealing assembly includes a first shell and a second shell, a fixing ring is fixed on the first shell, a rotating ring is rotatably connected to the first shell, a first telescopic spring is fixedly connected to the rotating ring, a supporting block is fixed on the first shell, a damping rod is fixed on the supporting block, a second telescopic spring is sleeved on the damping rod, a pressure block is fixed on the other end of the damping rod, and a bolt is threadedly connected to the supporting block.

[0008] As a preferred implementation of a high-sealing structure of a gearbox, one end of the second telescopic spring is fixedly connected to the support block, and the other end of the second telescopic spring is fixedly connected to the pressing block.

[0009] The beneficial effect of adopting the above further scheme is: since one end of the second telescopic spring is fixedly connected to the support block, and the other end of the second telescopic spring is fixedly connected to the pressure block, the second telescopic spring can provide an elastic effect on the pressure block, so that the damping rod, the second telescopic spring and the pressure block can provide a vibration reduction effect on the rotating shaft of the gear box body.

[0010] As a preferred implementation of a high-sealing structure of a gearbox, the first shell and the second shell are both fixed on the gearbox body, and sealing gaskets are both fixed on the first shell and the second shell.

[0013] The beneficial effect of adopting the above further scheme is: since the first fixed seat is fixed on the first shell, and the second fixed seat is fixed on the second shell, the first shell can support and fix the first fixed seat, and the second shell can support and fix the second fixed seat. Since the first fixed seat is rotatably connected with a rotating block, the first fixed seat can limit the rotation of the rotating block.

[0014] As a preferred implementation of a gearbox high sealing structure, a telescopic rod is fixed on the rotating block, a third telescopic spring is sleeved on the telescopic rod, a clamping block is fixed on the telescopic rod, and the clamping block is slidably connected to the rotating block.

[0015] The beneficial effect of adopting the above further scheme is: since a telescopic rod is fixed on the rotating block and a third telescopic spring is sleeved on the telescopic rod, the telescopic rod can limit the extension and retraction of the third telescopic spring; since a clamping block is fixed on the telescopic rod, when the clamping block moves, the telescopic rod can limit the movement of the clamping block.

[0016] As a preferred implementation of a gearbox high sealing structure, one end of the third telescopic spring is fixedly connected to the rotating block, and the other end of the third telescopic spring is fixedly connected to the clamping block, and the clamping block is fixed to the second fixed seat.

[0017] The beneficial effect of adopting the above further scheme is: because one end of the third telescopic spring is fixedly connected to the rotating block, and the other end of the third telescopic spring is fixedly connected to the clamping block, the third telescopic spring can provide an elastic effect on the clamping block, so that the clamping block can be clamped and fixed on the second fixed seat.

Tightening the bolts can fix the first shell and the second shell, thereby solving the technical problem that the service life of the sealing structure is affected by wear of the gear box body during operation.

[0028] 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.

[0029] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a gearbox high sealing structure, comprising a gearbox body 1, a sealing assembly 2 is arranged on the gearbox body 1, and a fixing assembly 3 is arranged on the sealing assembly 2;

[0030] like Figure 1 - Figure 3 As shown, the sealing assembly 2 includes a first shell 21 and a second shell 22, a fixing ring 23 is fixed on the first shell 21, a rotating ring 24 is rotatably connected to the first shell 21, a first telescopic spring 25 is fixedly connected to the rotating ring 24, a supporting block 26 is fixed on the first shell 21, a damping rod 27 is fixed on the supporting block 26, a second telescopic spring 28 is sleeved on the damping rod 27, a pressing block 29 is fixed to the other end of the damping rod 27, and a bolt 210 is threadedly connected to the supporting block 26. In specific operation, the first shell 21 and the second shell 22 are first inserted into the rotating shaft of the gear box body 1, and then the rotating shaft is sealed by the fixing ring 23 to prevent lubricating oil leakage, and then, the rotating ring 24 and the first telescopic spring 25 are fixedly connected. The cooperation of the spring 25 ensures that the rotating shaft of the gear box body 1 will not wear the sealing structure during long-term operation, thereby protecting the integrity of the sealing structure. In addition, the cooperation of the damping rod 27, the second telescopic spring 28 and the pressure block 29 arranged on the support block 26 can buffer and tighten the first shell 21 and the second shell 22, reducing the vibration generated by the rotating shaft during rotation, thereby improving the operating stability of the gear box. Finally, by tightening the bolts 210, the first shell 21 and the second shell 22 can be firmly fixed together, further ensuring the sealing and stability of the gear box, thereby solving the technical problem that the gear box body 1 affects the service life of the sealing structure due to wear during operation.

[0031] The above solution still has the problem that the sealing component 2 cannot be stably fixed when sealing the gear box body 1. Figure 1 - Figure 3As shown: one end of the second telescopic spring 28 is fixedly connected to the support block 26, and the other end of the second telescopic spring 28 is fixedly connected to the pressure block 29. Since one end of the second telescopic spring 28 is fixedly connected to the support block 26, and the other end of the second telescopic spring 28 is fixedly connected to the pressure block 29, the second telescopic spring 28 can provide an elastic effect on the pressure block 29, so that the damping rod 27, the second telescopic spring 28 and the pressure block 29 can provide a vibration reduction effect on the rotating shaft of the gear box body 1. The first shell 21 and the second shell 22 are both fixed to the gear box body 1. The first shell 21 and the second shell 22 are both fixed with a sealing gasket 211. Since the first shell 21 and the second shell 22 are both fixed to the gear box body 1, the first shell 21 and the second shell 22 can provide a sealing effect for the gear box body 1. Since the first shell 21 and the second shell 22 are both fixed with the sealing gasket 211, the sealing gasket 211 can increase the sealing effect of the connection between the first shell 21 and the second shell 22.

[0032] like Figure 1 as well as Figure 4 As shown, the fixing assembly 3 includes a first fixing seat 31 and a second fixing seat 36. The first fixing seat 31 is fixed on the first shell 21, and the second fixing seat 36 is fixed on the second shell 22. The first fixing seat 31 is rotatably connected with a rotating block 32. Since the first fixing seat 31 is fixed on the first shell 21, and the second fixing seat 36 is fixed on the second shell 22, the first shell 21 can support and fix the first fixing seat 31, and the second shell 22 can support and fix the second fixing seat 36. Since the first fixing seat 31 is rotatably connected with the rotating block 32, the first fixing seat 31 can limit the rotation of the rotating block 32. A telescopic rod 33 is fixed on the rotating block 32, and a third telescopic spring 34 is sleeved on the telescopic rod 33. A clamping block 35 is fixed on the telescopic rod 33, and the clamping block 35 is slidably connected to On the rotating block 32, since a telescopic rod 33 is fixed on the rotating block 32, and a third telescopic spring 34 is sleeved on the telescopic rod 33, the telescopic rod 33 can limit the extension and retraction of the third telescopic spring 34. Since a clamping block 35 is fixed on the telescopic rod 33, when the clamping block 35 moves, the telescopic rod 33 can limit the movement of the clamping block 35. One end of the third telescopic spring 34 is fixedly connected to the rotating block 32, and the other end of the third telescopic spring 34 is fixedly connected to the clamping block 35. The clamping block 35 is fixed on the second fixed seat 36. Since one end of the third telescopic spring 34 is fixedly connected to the rotating block 32, and the other end of the third telescopic spring 34 is fixedly connected to the clamping block 35, the third telescopic spring 34 can provide an elastic effect on the clamping block 35, so that the clamping block 35 can be clamped and fixed on the second fixed seat 36.

[0033] Working principle:

[0034] like Figure 1 - Figure 4 As shown, first, the first housing 21 and the second housing 22 are inserted into the rotating shaft of the gear box body 1, and then the rotating shaft is sealed by the fixing ring 23 to prevent leakage of lubricating oil. Then, through the cooperation of the rotating ring 24 and the first telescopic spring 25, the rotating shaft of the gear box body 1 will not wear the sealing structure during long-term operation, thereby protecting the integrity of the sealing structure. In addition, the cooperation of the damping rod 27, the second telescopic spring 28 and the pressing block 29 provided on the support block 26 can buffer and tighten the first housing 21 and the second housing 22, reduce the vibration generated by the rotating shaft during the rotation process, thereby improving the running stability of the gear box. Finally, by tightening the bolt 210, the first housing 2 The first housing 21 and the second housing 22 can be firmly fixed together, further ensuring the sealing and stability of the gear box. The rotating block 32 is rotated to the second fixing seat 36, and then the clamping block 35 is pulled. Through the cooperation of the telescopic rod 33 and the third telescopic spring 34, the clamping block 35 can be fixed on the second fixing seat 36, so that the rotating block 32 can be fixed on the second fixing seat 36, so that the first housing 21 and the second housing 22 can be fixed, which improves the stability and service life of the gear box and facilitates the disassembly and installation of the sealing assembly 2. When the gear box needs to be replaced or repaired, the first housing 21 and the second housing 22 can be easily separated by only reverse operation, which greatly improves the convenience of repair and replacement.
