Abstract
The utility model discloses a kind of speed reducer assemblies reducing oil sealing pressure.The speed reducer assembly for reducing oil sealing pressure includes reducer shell, flange, oil sealing and dust cover, one end of the flange is inserted into reducing gearbox body and fixed thereto, the oil sealing is located between flange outer wall and reducer shell inner wall, the bearing with coaxial thereto is equipped in the reducing gearbox body, decompression part is equipped between the bearing and flange, the reducer shell inner wall is equipped with drainback passage, and the decompression part is between drainback passage and oil sealing, one end of the dust cover is sleeved on the flange, the other end of the dust cover is sleeved on reducer shell.The speed reducer assembly that the utility model can reduce oil sealing pressure is avoided that fluid directly impacts oil sealing, ensures that oil sealing will not oil leak.
Description
Technical field
The utility model is related to decelerator oil encapsulation technique fields, more particularly to a kind of retarder reducing oil sealing pressure
Assembly.
Background technology
The main tooth oil sealing of traditional main reducing gear, the gear oil flowed back to by reducer shell back oil road directly pour impact
On main tooth oil sealing, if running at high speed at this time, gear rotational speed aggravation, impact meeting of the fluid flowed back at this time from back oil road to oil sealing
Bigger, equally to the carrying of oil sealing and wear resistance test aggravation.
Utility model content
Oil sealing is impacted the technical problem to be solved by the present invention is to provide a kind of fluid of reduction back oil road outflow
Speed reducer assembly.
To solve the above problems, the utility model provides a kind of speed reducer assembly reducing oil sealing pressure, it is described to subtract
The speed reducer assembly of few oil sealing pressure includes reducer shell, flange, oil sealing and dust cover, and one end of the flange, which is inserted into, slows down
In device shell and fixed thereto, the oil sealing is located between flange outer wall and reducer shell inner wall, in the reducing gearbox body
Decompression part is equipped with equipped with the bearing with coaxial thereto, between the bearing and flange, the reducer shell inner wall is equipped with oil return
Channel, and the decompression part, between drainback passage and oil sealing, one end of the dust cover is sleeved on the flange, described
The other end of dust cover is sleeved on reducer shell.
Further, the oil sealing includes keel and rubber bodies, and the keel are fixed in rubber bodies.
Further, the rubber bodies are equipped with and pull piece.
Further, the decompression part is plain washer.
Further, the decompression part is equipped with spoiler.
Further, the spoiler is arc-shaped.
The speed reducer assembly that the utility model can reduce oil sealing pressure is equipped with decompression part between oil return runner and oil sealing, subtracts
Casting die can stop the oil that reflux oil duct flows back to, and avoid fluid from directly impacting oil sealing, alleviate the pressure of oil sealing, extend making for oil sealing
Use the service life.
Description of the drawings
Fig. 1 is the structural schematic diagram of the better embodiment for the speed reducer assembly that the utility model can reduce oil sealing pressure.
Fig. 2 is the partial enlarged view of A in Fig. 1.
Fig. 3 is the partial structural diagram for depressurizing part.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1
As depicted in figs. 1 and 2, the utility model can reduce the better embodiment packet of the speed reducer assembly of 3 pressure of oil sealing
Include reducer shell 1, flange 2, oil sealing 3 and dust cover 5.It is interior and solid therewith that reducer shell 1 is inserted into one end of the flange 2
It is fixed.The oil sealing 3 is located between 1 inner wall of 2 outer wall of flange and reducer shell；The oil sealing 3 includes keel 32 and rubber bodies 31,
The keel 32 are fixed in rubber bodies 31, and keel 32 increase the intensity of rubber bodies 31, it is ensured that can bear sufficiently large pressure；Institute
Rubber bodies 31 are stated equipped with piece is pullled, take out rubber bodies 31 from installation site when being needed replacing convenient for the later stage.The dust cover 5
One end be sleeved on the flange 2, the other end of the dust cover 5 is sleeved on reducer shell 1, and dust cover 5 is by oil sealing 3
Sealing, protects oil sealing 3, and oil sealing 3 is made not corroded by sundries such as dust, extends the service life of oil sealing 3.The retarder
It is equipped with the bearing 12 coaxial with flange 2 in shell 1, decompression part 4, the reducing gearbox are equipped between the bearing 12 and flange 2
1 inner wall of body is equipped with drainback passage, and the decompression part 4 is between drainback passage and oil sealing 3.Wherein, the decompression part 4 is flat
Washer ensures the intensity of decompression part 4, can bear sufficiently large impact force.
It is equipped with decompression part 4 between oil return runner and oil sealing 3, and is fixed with bearing 12 by part 4 is depressurized by flange 2, returns
The oil that stream oil duct 11 flows back to directly percussion directly impacts oil sealing 3 so as to avoid fluid, alleviates oil sealing 3 on decompression part 4
Pressure, the phenomenon that extending the service life of oil sealing 3, avoid oil leak.
Embodiment 2
As shown in figure 3, the decompression part 4 is equipped with spoiler 41, alleviate impact of the fluid to decompression part 4.The flow-disturbing
Piece 41 is arc-shaped, and the direction of spoiler 41 is irregularly arranged, i.e., the direction of adjacent spoiler 41 is different, further to drop
Impact of the low fluid to decompression part 4.
It these are only the embodiment of the utility model, it does not limit the scope of the patent of the present invention, every profit
The equivalent structure made by the utility model specification and accompanying drawing content is directly or indirectly used in other relevant technology necks
Domain, similarly within the scope of patent protection of the utility model.
