Abstract
The utility model is related to a kind of non-maintaining devices of Helicopter Main Reducer oil leak, including seal receptacle, sealing device, pipe fitting, oil pipe, the sealing device is mounted on seal receptacle, on seal receptacle threaded hole is provided with below the outside of sealing device, pipe fitting is mounted on threaded hole, oil pipe one end is mounted on pipe fitting, other end connection oil trap.The utility model can not only provide the lubricating oil for collecting dynamic sealing leakage at single, while collect the collection of entire main reducing gear.Therefore, the utility model can reduce or remit the ground maintenance of oil leak to avoid pollution of the helicopter oil leak to ground.
Description
Technical field
The utility model is related to a kind of non-maintaining devices of Helicopter Main Reducer oil leak, are moved for Helicopter Main Reducer close
The collection of lubrication leakage is sealed, exempts oil leak ground maintenance.
Background technology
At present, there are more sealings, predominantly static seal and dynamic sealing for Helicopter Main Reducer.Static seal include O-ring,
Thread seal etc., is not related to oil leak generally；Dynamic sealing includes mechanical seal, lip oil sealing etc., and general oil leak is more, this is because
The contact relative rotation sealing of dynamic sealing, causes dynamic sealing inevitably to have oil leak.Although dynamic sealing oil leak amount is few,
The use of Helicopter Main Reducer not being interfered with, but due to there is no collection lubricating oil, lubricating oil will be dropped on helicopter platform, then with
The action of helicopter high maneuver, blowing by gravity and wind is spread all over everywhere, taken for ground maintenance by lubricating oil
When it is laborious, be one greatly test.
Invention content
The purpose of this utility model is to provide a kind of non-maintaining device of Helicopter Main Reducer oil leak, avoids helicopter oil leak
The ground maintenance of oil leak is reduced or remitted in pollution to ground.
The technical solution of the utility model is, the non-maintaining device of Helicopter Main Reducer oil leak include seal receptacle,
Sealing device, pipe fitting, oil pipe, the sealing device are mounted on seal receptacle, positioned at the outer of sealing device on seal receptacle
Threaded hole is provided with below side, pipe fitting is mounted on threaded hole, and oil pipe one end is mounted on pipe fitting, other end connection collection
Oil groove.The seal receptacle end set has the annular flange with interior extension, and oil pump is provided on oil pipe.
The utility model is provided with pipe fitting and oil pipe, and the oil leaked by sealing device enters oil-collecting by the access
In slot, do not fall directly on ground；Seal receptacle end set has the annular flange with interior extension, and lubrication leakage can be prevented excessive
And it overflows；Oil pump is provided on oil pipe, the effect for because oil pipe is long, influencing to collect draining off leak oil can be prevented.This practicality is new
Type can not only provide the lubricating oil for collecting dynamic sealing leakage at single, while collect the collection of entire main reducing gear.Therefore, this reality
The ground maintenance of oil leak can be reduced or remitted with novel to avoid pollution of the helicopter oil leak to ground.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of seal receptacle.
Specific embodiment
As shown in the figure, the non-maintaining device of Helicopter Main Reducer oil leak includes seal receptacle 1, sealing device 2, pipe fitting 3, oil
Pipe 4, the sealing device 2 are mounted on seal receptacle 1, are provided with below the outside of sealing device on seal receptacle 1
Threaded hole, pipe fitting 3 are mounted on threaded hole, and 4 one end of oil pipe is mounted on pipe fitting 3, other end connection oil trap.Described
1 end set of seal receptacle have with the annular flange of interior extension 5, be provided with oil pump on oil pipe 4.
