Pivoting support bearing is the critical component in the pitch-controlled system and yaw system of wind-driven generator, according to wind-power electricity generation
Active force feature of the machine pivoting support bearing by radial load, axial load and tilting moment, it is desirable to which bearing will have higher
Intensity and bearing capacity, being capable of smooth long term running.
Pivoting support of windmill generator bearing is made up of axis inner ring on the same line and outer ring, inner ring and outer ring
Between be evenly equipped with steel ball, inner ring and outer ring can relatively rotate in the both sides of steel ball.When using, one is injected to Bearing inner die cavity
Quantitative lubricating grease, in order to prevent bearing die cavity internal lubrication fat to be lost in, it is to avoid steel ball occurs dry friction with bearing internal external circle, together
When also for the dust prevented in external environment enter Bearing inner die cavity, the upper and lower ends face between the inner ring of bearing and outer ring
Rubber seal is installed.
Pivoting support of windmill generator bearing rubber seal of the prior art has the sealing ring body of annular, close
One end of seal body has the installing handle of annular, and the other end has the sealing limb that section is V-arrangement, by installing handle, sealing ring
Body and sealing limb are formed with two seals loop, and its middle section is the sealing limb of V-arrangement towards a limb oil sealing of inner side, outside
The oil sealing simultaneously of one limb of side and envelope dirt.
Pivoting support of windmill generator bearing rubber seal is in field high altitude environmental work throughout the year, and working condition is disliked
It is bad, and as wind power technology develops, present Megawatt fan is become by original multikilowatt, correspondingly the chi of pivoting support bearing
Very little also increasing, this just has requirement higher, pivoting support axle to the sealing property of pivoting support bearing rubber seal
The structure for holding sealing ring greatly affected the sealing property of sealing ring.Above-mentioned pivoting support of windmill generator of the prior art
Bearing sealed ring, it is difficult to meet the requirement of Megawatt fan pivoting support bearing sealing, bearing grease leakage problem never has and obtains
Effectively solve.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of pivoting support of windmill generator bearing rubber seal,
The utility model has good sealing function for large scale bearing, particularly Megawatt fan pivoting support bearing, can be with
Effectively prevent the generation of bearing grease leakage problem.
In order to solve the above technical problems, a kind of pivoting support of windmill generator bearing rubber seal of the utility model, should
Pivoting support of windmill generator bearing has the inner ring and outer ring for cooperating, and it is approximate square to have section on the excircle of inner ring
The annular installing handle groove of shape, it is that approximate rectangular ring packing limb is installed that outer ring accordingly also offers section towards the side of inner ring
Groove, one end that the rubber seal has O-ring seal body, O-ring seal body has annular installing handle, the other end
With ring packing limb, the first sealing limb that the ring packing limb is stretched out by upward front, forward obliquely downward stretch out the
The 3rd sealing limb that two sealing limbs and downward rear ramp are stretched out is constituted, and the second sealing limb has upper and lower sealing, works as rubber
When sealing ring is loaded on pivoting support of windmill generator bearing, the annular installing handle is located in the annular installing handle groove, institute
State ring packing limb second, third sealing limb be located at the ring packing limb mounting groove in, first sealing limb be resisted against annular
Outer ring edge on the outside of sealing limb mounting groove, the upper and lower sealing of the second sealing limb is resisted against the installation of ring packing limb respectively
On the groove lateral surface and groove bottom of groove, the 3rd sealing limb is resisted against on the groove medial surface of ring packing limb mounting groove.
Using the pivoting support of windmill generator bearing rubber seal of said structure, pivoting support of windmill generator is sealed
During bearing, four road sealed circuits can be formed, had for large scale bearing, particularly Megawatt fan pivoting support bearing good
Sealing function, can effectively prevent the generation of bearing grease leakage problem.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is a kind of section structure schematic diagram of pivoting support of windmill generator bearing rubber seal of the utility model.
Assembling structure schematic diagram when Fig. 2 is the utility model loaded on pivoting support of windmill generator bearing.
