Abstract
The utility model provides a kind of main shaft cooling duct sealing ring, including main shaft, it is characterised in that be provided with N1 roads main shaft runner on the main shaft, and wherein N1 is positive integer and N1 >=2；First sealing ring and the second sealing ring, it is separately positioned on the cylindrical side of each main shaft runner, and be in be symmetrical arranged up and down, each main shaft runner is sealed up and down, main shaft cooling oil is respectively double-decker in the first sealing ring and the second sealing ring internal circulation flow, first sealing ring and the second sealing ring.The beneficial effects of the utility model are：1st, double containment, dual fail-safe are realized using double-layer double-direction sealing ring on main shaft.2nd, the main material of this sealing ring is rubber, with the addition of oil resistant, high temperature resistant material on this basis, substantially increases the service life of sealing ring.
Description
Technical field
The utility model is related to main shaft cooling technology field, and in particular to a kind of main shaft cooling duct sealing ring.
Background technology
Main shaft cooling is all that the main shaft oil for adopting is cooled down mostly, and sealing ring plays a part of to seal cooling duct, it is ensured that main shaft
Oil does not leak outside.
Main shaft oil has certain corrosivity, and the sealing ring of market is all to adopt quality of rubber materials, in prolonged immersion oil, holds
It is also easy to produce hardening rotten, so as to deform, causes main shaft oil to leak outside.
It is generally adopted by individual layer sealing on the market, in installation process, has deviation unavoidably, installation is relatively difficult, one
As all repeatedly install.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of main shaft cooling duct sealing ring.
The utility model provide technical scheme be：
A kind of main shaft cooling duct sealing ring, including main shaft, it is characterised in that be provided with N1 roads main shaft stream on the main shaft
Road, wherein N1 are positive integer and N1 >=2；
First sealing ring and the second sealing ring, are separately positioned on the cylindrical side of each main shaft runner, and set in symmetrical above and below
Put, each main shaft runner is sealed up and down, main shaft cooling oil is in the first sealing ring and the second sealing ring internal circulation flow, institute
State the first sealing ring and the second sealing ring is respectively double-decker.
Preferably, the first sealing ring and the second sealing ring are made up of quality of rubber materials.
The beneficial effects of the utility model are：
1st, double containment, dual fail-safe are realized using double-layer double-direction sealing ring on main shaft.
2nd, the main material of this sealing ring is rubber, with the addition of oil resistant, high temperature resistant material on this basis, substantially increases close
The service life of seal.
Description of the drawings
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the structural representation of the first sealing ring or the second sealing ring in the utility model.
Specific embodiment
Describe the utility model, here signal of the present utility model below in conjunction with accompanying drawing and specific embodiment in detail
Property embodiment and explanation be used for explaining the utility model, but be not intended as to restriction of the present utility model.
Referring to figs. 1 to Fig. 2, a kind of main shaft cooling duct sealing ring, including main shaft 5, it is characterised in that set on the main shaft 5
N1 roads main shaft runner is equipped with, wherein N1 is positive integer and N1 >=2；
First sealing ring 1 and the second sealing ring 2, are separately positioned on the cylindrical side of each main shaft runner, and in symmetrical above and below
Arrange, each main shaft runner is sealed up and down, 5 cooling oil of main shaft is in 2 inner recirculation flow of the first sealing ring 1 and the second sealing ring
Dynamic.First sealing ring 1 and the second sealing ring 2 are respectively double-decker.Cooling main shaft is played during main shaft 5 operates
The effect of 5 inner and outer walls.2 exclusive design double containment main shaft runner of first sealing ring 1 and the second sealing ring, seals double guarantor simultaneously
Danger.And the corrosion resistant material of oil resistant is with the addition of in the case where main material is rubber so as to more robust, indeformable.
Above the technical scheme disclosed in the utility model embodiment is described in detail, used herein specifically
Embodiment is set forth to the principle of the utility model embodiment and embodiment, and the explanation of above example is only applicable to
Help the principle for understanding the utility model embodiment；Simultaneously for one of ordinary skill in the art, according to the utility model reality
Example is applied, be will change in specific embodiment and range of application, in sum, this specification content should not be understood
It is to restriction of the present utility model.
