Description
Technical field
The utility model is related to a kind of wind-power electricity generation bearing.
Background technology
The working environment of wind-driven generator is generally relatively more severe, is used because necessarily be in the abundant area of wind resource, because
This is higher for each technical property requirements of wind-driven generator, particularly with its main parts, such as bearing, the design of bearing
Reasonability affects the performance and service life of generator.And design, lubrication system for the Each part of bearing sets
Meter can all influence the use of bearing.Big multiple bearing is moistened only by oil inlet passage with the lubricating oil in oil discharge passage at present
It is sliding, and run after a period of time, it is necessary in time to adding lubricating oil in bearing, and the excessive or lubricating oil of lubricating oil addition is reduced
The performance of bearing will be influenceed, bearing service life is reduced, so that the performance of motor is influenceed, it is solid for bearing rigidity in addition
Structure due to main shaft is also unfavorable for maintenance.
The content of the invention
To solve the above problems, the utility model provides a kind of wind-power electricity generation bearing, and convenient maintenance is reduced and added to bearing
The frequency of lubricating oil, may be such that lubricating oil plays the maximal efficiency to bearing lubrication, extend the service life of bearing.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of wind-power electricity generation bearing, including bearing outer ring and two bearing inner races side by side, in bearing outer ring and two axles
Hold and be respectively equipped with a row steel ball between inner ring, the ball orbit of biserial annular, double row ball are provided with the inner surface of bearing outer ring
Surface of the track respectively with two row steel balls is engaged, and the ball orbit of annular is respectively equipped with the outer surface of two bearing inner races,
The surface of two ball orbits of bearing inner race outer surface respectively with two row steel balls is engaged, in the biserial of bearing outer ring inner surface
Two are respectively equipped with ball orbit and are located at steel ball both sides and annular groove side by side, in the ball rail of bearing inner race outer surface
Two also are provided with road and are located at steel ball both sides and annular groove side by side, oil was provided between bearing outer ring and bearing inner race
Chamber, is provided with the outside of bearing inner race and crosses the oil inlet passage that oil pocket is communicated, and is provided with bearing outer ring and crosses what oil pocket was communicated
Oil drain passage, two bearing inner races are connected by screw.
The utility model is convenient to be repaired, and reduces the frequency that lubricating oil is added to bearing, may be such that lubricating oil is played to bearing
The maximal efficiency of lubrication, extends the service life of bearing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the mplifying structure schematic diagram of A in Fig. 1.
Wherein：In bearing outer ring 1, bearing outer ring ball orbit 1-1, bearing outer ring groove 1-2, oil drain passage 1-3, bearing
Circle 2, bearing inner race ball orbit 2-1, bearing inner race groove 2-2, oil inlet passage 2-3, steel ball 3, excessively screw 4, oil pocket 5.
Specific embodiment
It is described in further detail below in conjunction with the most preferred embodiment shown in accompanying drawing：
As shown in Fig. 1~Fig. 2, a kind of wind-power electricity generation bearing, including bearing outer ring 1 and two bearing inner races 2 side by side,
A row steel ball 3 is respectively equipped between bearing outer ring 1 and two bearing inner races 2, biserial annular is provided with the inner surface of bearing outer ring 1
Bearing outer ring ball orbit 1-1, surfaces of the double-row bearing outer ring ball orbit 1-1 respectively with two row steel balls 3 is engaged, two
The outer surface of individual bearing inner race 2 is respectively equipped with the bearing inner race ball orbit 2-1 of annular, two axles of the outer surface of bearing inner race 2
Hold surfaces of the inner ring ball orbit 2-1 respectively with two row steel balls 3 to be engaged, in the double-row bearing outer ring of the inner surface of bearing outer ring 1
Two are respectively equipped with ball orbit 1-1 and are located at the both sides of steel ball 3 and annular bearing outer ring groove 1-2 side by side, in bearing
Enclose and two also are provided with the bearing inner race ball orbit 2-1 of 2 outer surfaces positioned at the both sides of steel ball 3 and annular bearing inner race side by side
Groove 2-2, was provided with oil pocket 5 between bearing outer ring 1 and bearing inner race 2, is provided with the outside of bearing inner race 2 and crosses oil pocket 5
The oil inlet passage 2-3 for communicating, is provided with bearing outer ring 1 and crosses the oil drain passage 1-3 that oil pocket 5 is communicated, and two bearing inner races 2 lead to
Screw 4 is crossed to connect.
When using, oil inlet passage 2-3 addition lubricating oil, lubricating oil flows by oil pocket 5, is rolled through steel ball 3, is delivered to each
Bearing outer ring groove 1-2, bearing inner race groove 2-2, can finally be discharged by oil drain passage 1-3, each bearing outer ring groove 1-2,
A part of lubricating oil can be stored in bearing inner race groove 2-2, with the use of bearing, each bearing outer ring groove 1-2, bearing inner race
Lubricating oil in groove 2-2 can in time supplement the loss of lubricating oil in oil pocket 5, reduce the frequency that lubricating oil is added to bearing,
May be such that lubricating oil plays the maximal efficiency to bearing lubrication, and two bearing inner races 2 by the installation easy to connect of screw 4, side
Just detachable maintaining, extends the service life of bearing.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
