Abstract
The utility model is related to one kind and is directed to sealing structure on the input of wind-driven generator gear-box and output shaft, including mechanically-sealing apparatus, it is characterized in that, the input being related to or output shaft are hollow shaft, the disc of the mechanically-sealing apparatus includes annulus disc and disk disc, they with hollow shaft close to being interference fitted successively, and wherein annulus disc inwall is provided with the annular groove for being used for placing O-ring seal, and equipped with O-ring seal.
Description
Technical field
The utility model is related to the hollow input in a kind of mechanically-sealing apparatus, especially a kind of wind-driven generator wheel-box
The disc structure being related in the mechanically-sealing apparatus that axle and hollow output shaft are 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 cost is low, floor space is small, the convenient advantage of maintaining, especially large-scale water-power plant, and storage reservoir is also easy to pair
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 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 be twisted 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 can not bear to get rid of
Oil ring dries the high temperature of suit timing；If reducing the magnitude of interference to reduce fitting temperature, it can not meet after axle stress again, disc and axle
Fitting part area, in 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 utility model is：Input or output shaft for wind power generation gear case use what is faced during hollow shaft
Leakage is directed to sealing structure in the input of wind-driven generator gear-box and output shaft there is provided one kind.
What the purpose of this utility model was realized in：One kind is directed to the input of wind-driven generator gear-box and output shaft
Upper sealing structure, including mechanically-sealing apparatus, it is characterised in that the input being related to or output shaft are hollow shaft, the machinery is close
The disc of seal apparatus includes annulus disc and disk disc, and they with hollow shaft close to being interference fitted successively, wherein round
Ring disc inwall is provided with the annular groove for being used for placing O-ring seal, and equipped with O-ring seal.
In the utility model, the depth that annulus disc inwall places the annular groove of O-ring seal is straight less than O-ring seal
The 1/5-1/2 in footpath, the sectional area of annular groove is more than the cross-sectional area of O-ring seal.
In the utility model, the annular groove that annulus disc inwall places O-ring seal is located at itself and the friendship of disk disc
Remittance end inwall.
In the utility model, the end wall of described annulus disc is provided with dismounting screw.
In the utility model, the installation magnitude of interference of annulus disc is less than disk disc.
The utility model has the advantage of because input or output shaft are hollow shaft, the disc of mechanically-sealing apparatus adopts
Combined with annulus disc and disk disc, they with hollow shaft close to being interference fitted successively, wherein annulus disc inwall
Provided with the annular groove for placing O-ring seal, and equipped with O-ring seal, it can effectively prevent lubricating oil by by O-ring seal
Disc and between centers seepage.Because the depth that annulus disc inwall places the annular groove of O-ring seal is 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, can implement precompression to O-ring seal, make it
It is seamless applying between hollow shaft and disc, meanwhile, the sectional area of annular groove can provide enough receiving skies for O-ring seal
Between, especially when the deformation that is distorted after hollow shaft stress, O-ring seal still can compensate its deflection.Because annulus is got rid of
The end wall of oil ring is provided with dismounting screw, and the installation magnitude of interference of annulus disc is less than disk disc, can be single in use
Solely by dismantling the Bolt dismantling annulus disc that screw is configured, replacement o sealing ring enormously simplify mechanically-sealing apparatus
Maintenance cost.The utility model compact conformation.
Brief description of the drawings
Fig. 1 is the structural representation of utility model embodiment.
In figure, 1, hollow shaft, 2, annulus disc, 3, O-ring seal, 4, disk disc, 5, dismounting screw.
Embodiment
Accompanying drawing discloses a kind of concrete structure for embodiment that the utility model is related to without limitation, below in conjunction with the accompanying drawings
The utility model patent is further described.
As seen from Figure 1, the utility model includes mechanically-sealing apparatus, wherein, the input or output shaft being related to are hollow
Axle 1, the disc of the mechanically-sealing apparatus includes annulus disc 2 and disk disc 4, they close to successively with hollow shaft
1 interference fit, the wherein inwall of annulus disc 2 are provided with the annular groove for being used for placing O-ring seal 3, and equipped 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 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 is got rid of
The end wall of oil ring 2 is provided with dismounting screw 5.
When it is implemented, the installation magnitude of interference of annulus disc is less than disk disc.
