Abstract
The utility model discloses the new many lip wind-powered turntable bearing sealing rings of one kind, belong to technical field of sealing technology.The utility model section is included in body of rubber, body of rubber along the tiltedly lower epipharynx and outer lip extended out with oblique direction, and the main lip in Chun Hefu extended out along vertical and horizontal direction；Epipharynx and outer lip are symmetrical along body of rubber center line, the C-shaped double fastener angle design of adjacent edge；Main side lip both sides are respectively provided with corrugated and dentation, and auxiliary side lip outer side band has dentation；It is main in Chun Hefu after lip indentation sealing groove, epipharynx and outer lip are being formed radially interference fit with bearing ring.The utility model is designed using many lip formulas, meet the more requirement of wind-powered turntable bearing sealing surface, add the radial compression amount of epipharynx and outer lip and bearing ring, after turntable bearing long time running, being capable of automatic elastic restoration and compensation, seal closure loop is kept, the problem of wind-powered turntable bearing sealing ring uses rear poorly sealed for a long time is solved.
Description
Technical field
The utility model is related to technical field of sealing technology, is sealed more specifically to a kind of novel wind power turntable bearing
Circle.
Background technology
Wind-powered turntable bearing is a kind of extra large size bearing, is mainly used in the change oar and yaw system of wind power generating set, its
Middle pitch variable bearings are used to connect hub and blade, and yaw is used to connect tower and unit.It, which is dismounted, safeguards extremely difficult, together
When turntable bearing operationally partial denudation is polluted by sand and dust, water smoke, frost etc. encroach on outside, easily, sealing ring is used for bearing
Internal die cavity, which is isolated from the outside, to come, it is to avoid the leakage of internal lubrication fat and the entrance of introduced contaminants.Wind-powered turntable bearing is sealed
The validity of system and lasting reliability are the preconditions for ensureing turntable bearing long-time safe handling.
Wind-powered turntable bearing aloft work in the wild, required sealing surface is more, and inconvenience is safeguarded in sealing ring installation and maintenance, once
The problem of sealing ring occurs poorly sealed after a long time use, can not only cause Bearing inner lubricating grease leakage, can also cause
External contaminants enters Bearing inner and causes raceway to wear and tear or stuck phenomenon, causes wind-driven generator can not normal work
Make, in addition driving major accident.
The content of the invention
The purpose of this utility model is to solve turntable bearing sealing system, and to there is sealing surface more, and sealing ring makes for a long time
With it is rear occur poorly sealed the problem of there is provided the new many lip wind-powered turntable bearing sealing rings of one kind, meet wind-powered electricity generation rotating disk
The more requirement in bearing seal face, solves the problem of turntable bearing sealing ring uses rear poorly sealed for a long time.
To solve the above problems, technical solutions of the utility model are：Section includes body of rubber, edge respectively in body of rubber
Epipharynx and outer lip that tiltedly lower and oblique direction extends out, and extended out along the vertical and horizontal directions respectively in body of rubber
The main lip in Chun Hefu.
It is further preferred that described epipharynx and outer lip is symmetrical along body of rubber center line, the adjacent edge of epipharynx and outer lip
The design of C-shaped double fastener angle, wherein the angle of main angle α is more than time angle β angle, such structure effectively increase epipharynx and
The radial compression amount of outer lip and bearing ring, realizes the elastic recoil of rubber after wind-powered turntable bearing long time running.
It is further preferred that the main side lip both sides coordinated with seal groove are respectively provided with corrugated and dentation,
Dentation is carried on auxiliary side lip, such structure effectively increases the frictional force of outer fringe seal lip and seal groove, prevent sealing
Circle abjection and skidding.
It is further preferred that described sealing ring is after the indentation sealing groove of bearing ring upper surface, epipharynx and outer lip ride over
On the sealing surface of bearing ring, with bearing ring to be formed radially interference fit, the main lip in Chun Hefu and end face seal groove equal
For interference fit.
The beneficial effects of the utility model are to be designed using many lip formulas, meet wind-powered turntable bearing sealing surface more
Requirement, add the radial compression amount of epipharynx and outer lip and bearing ring, it is internal after wind-powered turntable bearing long time running
, being capable of automatic elastic restoration and compensation, holding seal closure in the case that grease pressure increases or bearing ring is deformed
Loop, prevents the leakage of internal lubrication fat and the invasion of introduced contaminants, and solve wind-powered turntable bearing sealing ring makes for a long time
With it is rear poorly sealed the problem of.
Brief description of the drawings
Fig. 1 be it is of the present utility model be many lip wind-powered turntable bearing sealing rings structural representation.
In figure：1st, body of rubber, 2, epipharynx, 3, outer lip, 4, auxiliary side lip, 5, main side lip.
Embodiment
The utility model is further described below with reference to specific embodiments and the drawings.
Embodiment 1

It is further preferred that described epipharynx (2) and outer lip (3) is symmetrical along body of rubber (1) center line, epipharynx and outer lip
The design of adjacent edge C-shaped double fastener angle, wherein the angle of main angle α is more than time angle β angle, such structure is effectively increased
The radial compression amount of epipharynx and outer lip and bearing ring, realizes that the elasticity of rubber after wind-powered turntable bearing long time running is returned
Position.
It is further preferred that main side lip (5) both sides coordinated with seal groove are respectively provided with corrugated and cdontoid process
Rise, dentation is carried on auxiliary side lip (4), such structure effectively increases the frictional force of outer fringe seal lip and seal groove, prevent
Only sealing ring abjection and skidding.
It is further preferred that described sealing ring is after the indentation sealing groove of bearing ring upper surface, epipharynx (2) and outer lip
(3) ride on the sealing surface of bearing ring, interference fit be formed radially with bearing ring, it is main in lip (5) and it is auxiliary while lip (4) with
End face seal groove is interference fit.
Schematically the utility model and embodiments thereof are described above, the description does not have restricted, accompanying drawing
Shown in be also one of embodiment of the present utility model, actual structure is not limited thereto.So, if this area
