The sealing structure is characterized in that the related input shaft or output shaft is a hollow shaft, an oil slinger of the mechanical sealing device comprises a round ring oil slinger and a round plate oil slinger, and the round ring oil slinger and the round plate oil slinger are close to each other and interference fitted with the hollow shaft in sequence, wherein the inner wall of the round ring oil slinger is provided with an annular groove used for putting an O-shaped sealing ring, and is provided with the O-shaped sealing ring.
Description
Technical field
The present invention relates to a kind of a kind of hollow input shaft in mechanically-sealing apparatus, especially wind-driven generator wheel-box and
The disc structure being related in the mechanically-sealing apparatus that hollow output shaft is used.
Background technology
Wind-power electricity generation, with the free of contamination advantage that generates electricity, compared with hydroelectric generation, has compared with traditional thermal power generation
Capital construction low cost, floor space are little, the convenient advantage of maintaining, especially large-scale water-power plant, and storage reservoir is also easy to right
Cause certain potential safety hazard in downstream.In wind-driven generator, gear-box is the critical component of wind-driven generator.
The Leakage of wind-driven generator wheel-box is always a difficult problem of China and foreign countries' gear box designs.For hollow shaft knot
Structure, traditional disc design is due to needing the early warning such as shrink disk, while the deformation that can twist during operation, causes longtime running
Later the phenomenon of permeability occurs between disc and axle.If being sealed using rubber parts, traditional rubber parts material cannot bear and get rid of
Oil ring dries the high temperature of suit timing；If reducing the magnitude of interference reducing fitting temperature, cannot meet again after axle stress, disc and axle
Fitting part area, in the face of this series of technical bottleneck, this area is highly desirable a kind of best solution.
The content of the invention
The purpose of invention is：The oil leak faced when input or output shaft for wind power generation gear case is using hollow shaft
Problem, there is provided one kind is directed to sealing structure on the input of wind-driven generator gear-box and output shaft.
The object of the present invention is achieved like this：One kind is directed to close on the input of wind-driven generator gear-box and output shaft
Seal structure, including mechanically-sealing apparatus, it is characterised in that the input being related to or output shaft are hollow shaft, the mechanical seal dress
The disc put includes annulus disc and disk disc, they close to successively with hollow shaft interference fit, wherein annulus gets rid of
Oil ring inwall is provided with for placing the annular groove of O-ring seal, and is furnished with O-ring seal.
In the present invention, annulus disc inwall places the depth of the annular groove of O-ring seal less than O-ring seal diameter
1/5-1/2, the sectional area of annular groove is more than the cross-sectional area of O-ring seal.
In the present invention, annulus disc inwall places the annular groove of O-ring seal and is located at itself and disk disc and crosses end
Inwall.
In the present invention, the end wall of described annulus disc is provided with dismounting screw.
In the present invention, the installation magnitude of interference of annulus disc is less than disk disc.
It is an advantage of the current invention that because input or output shaft are hollow shaft, the disc of mechanically-sealing apparatus is using circle
Ring disc and disk disc are combined, they close to successively with hollow shaft interference fit, wherein annulus disc inwall is provided with
For placing the annular groove of O-ring seal, and it is furnished with O-ring seal, can effectively prevents lubricating oil from getting rid of oil by by O-ring seal
Ring and between centers seepage.Because annulus disc inwall places the depth of the annular groove of O-ring seal less than the 1/ of O-ring seal diameter
5-1/2, the sectional area of annular groove can implement precompression so as to sky more than the cross-sectional area of O-ring seal to O-ring seal
It is seamless applying between heart axle and disc, meanwhile, the sectional area of annular groove can provide enough receiving spaces for O-ring seal,
Especially when the deformation that is distorted after hollow shaft stress, O-ring seal still can compensate its deflection.Due to annulus disc
End wall be provided with dismounting screw, and the installation magnitude of interference of annulus disc is less than disk disc, can individually lead in use
The Bolt dismantling annulus disc of dismounting screw configuration is crossed, replacement o sealing ring enormously simplify the maintenance of mechanically-sealing apparatus
Cost.Present configuration is compact.
Description of the drawings
Fig. 1 is the structural representation of inventive embodiments.
In figure, 1, hollow shaft, 2, annulus disc, 3, O-ring seal, 4, disk disc, 5, dismounting screw.
Specific embodiment
Accompanying drawing discloses without limitation a kind of concrete structure of embodiment according to the present invention, below in conjunction with the accompanying drawings to this
Patent of invention is further described.
As seen from Figure 1, the present invention includes mechanically-sealing apparatus, wherein, the input or output shaft being related to is hollow shaft 1,
The disc of the mechanically-sealing apparatus includes annulus disc 2 and disk disc 4, they close to successively with the mistake of hollow shaft 1
It is full of cooperation, the wherein inwall of annulus disc 2 is provided with for placing the annular groove of O-ring seal 3, and is furnished with O-ring seal 3.
In the present embodiment, the annular groove of the inwall of annulus disc 2 placement O-ring seal 3 is handed over positioned at it with disk disc 4
Remittance end inwall, the inwall of annulus disc 2 places the 1/5-1/ of the depth less than the diameter of O-ring seal 3 of the annular groove of O-ring seal 3
2, the sectional area of annular groove is more than the cross-sectional area of O-ring seal 3, it is ensured that annular groove can accommodate O-ring seal 3.Meanwhile, annulus gets rid of
The end wall of oil ring 2 is provided with dismounting screw 5.
When being embodied as, the installation magnitude of interference of annulus disc is less than disk disc.
