Abstract
The utility model relates to a slewing bearing for hybrid wind power generation. The slewing bearing is characterized by comprising a base ring, an upper shaft ring and a lower shaft ring, wherein an annular convex structure is arranged on the inner side face of the base ring; the cross section of the upper shaft ring is of a T-shaped structure and the cross section of the lower shaft ring is of an inverted Y-shaped structure; the upper shaft ring and the lower shaft ring are fixedly connected through a bolt which runs through a shaft ring mounting hole to form an integral shaft ring with an I-shaped cross section; two raceways are simultaneously arranged between the annular convex upper surface of the base ring and the upper and lower parts of the integral shaft ring; inner side raceways in the upper and lower raceways, close to axes, are angular contact ball bearing raceways in which balls are filled, while outer side raceways in the upper and lower raceways, way from axes, are thrust bearing raceways in which pin rollers are filled. The slewing bearing, through hybrid use of the angular contact ball bearing raceways and the cylindrical raceways in the raceway structures, can simultaneously bear axial force and lateral force thereof; a pin roller for bearing radial force is not required to be additionally arranged, so that manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of hybrid pivoting support used for wind power generation.
Background technique
Wind-power electricity generation is because its environmental protection has been subject to the great attention of world's every country in recent years, and wind-powered electricity generation industry development is quite rapid.Therefore wind energy power bearing has wide market prospects.Steel ball bearing on wind-driven generator generally has: driftage bearing, pitch variable bearings, dynamo bearing.Wind-driven generator is worked throughout the year in the wild, and it is in use directly exposed to rain, snow and sunlight and descends, and has Environmental Conditions severe, the feature that maintenance cost is high.Therefore to all having proposed very high requirement in generator set overall operation stability, impact resistance, working life.
In traditional generator unit structure with gear-box, though its pivoting support functional reliability is high, can meet the severe working environment in field, current pivoting support used for wind power generation is owing to being subject to axially and radial force simultaneously, therefore it generally adopts three roller path structures, blowout patche adopts " work " font flange arrangement, upper raceway together with arranging between " work " font upper flange lower surface of blowout patche and seat ring upper surface, lower raceway together with arranging between lower flange upper surface and the lower surface of seat ring, between the flange neck sidewall of " work " font and seat ring inner side surface, arrange and sidewinder.Although this kind of structure can meet axially and radial load, because the required precision of sidewindering is higher, exists manufacture cost higher, the shortcoming of job insecurity simultaneously.
Model utility content
The technical problems to be solved in the utility model is to provide the pivoting support hybrid used for wind power generation that a kind of fabricating cost simple in structure is low.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of hybrid pivoting support used for wind power generation, it is characterized in that: comprise seat ring, upper blowout patche, lower blowout patche, on seat ring, be evenly drilled with the seat ring mounting hole that distributes ringwise and connect the upper and lower end face of seat ring, the inner side surface of seat ring is an annular protrusion structure; The cross section of upper blowout patche is " T " character form structure, the cross section of lower blowout patche is for falling " T " character form structure, the corresponding blowout patche mounting hole distributing ringwise that is drilled with on upper blowout patche and lower blowout patche, upper and lower blowout patche is by being connected into the overall blowout patche of a cross section for " work " font through the bolt of blowout patche mounting hole, between dividing on the annular protrusion upper surface of seat ring and the top of overall blowout patche, raceway in twice is set, between dividing in the annular protrusion lower surface of seat ring and the bottom of overall blowout patche, raceway under twice is set; Inboard raceways near axis in described upper and lower raceway is the angular contact ball bearing structure raceway that can fill ball, in upper and lower raceway, is the thrust bearing raceway that can fill roller away from the outboard raceway of axis.
The utility model has the advantage of: adopt the upper and lower blowout patche structure of separated type, can realize smoothly the installation of cylinder rolling element in upper and lower raceway; Adopt angular contact ball raceway and cylindrical raceway and mix in roller path structure, can bear the axial and lateral force of pivoting support simultaneously, without the roller that bearing radial force is set in addition, reduced manufacture cost.
Brief description of the drawings
Fig. 1 is hybrid pivoting support structural representation used for wind power generation in the utility model.
Embodiment
As shown in Figure 1, comprise seat ring 1, upper blowout patche 2, lower blowout patche 3, be evenly drilled with the seat ring mounting hole 11 that distributes ringwise and connect seat ring 1 upper and lower end face on seat ring 1, the inner side surface of seat ring 1 is an annular protrusion structure.
The cross section of upper blowout patche 2 is " T " character form structure, the cross section of lower blowout patche 2 is for falling " T " character form structure, the corresponding blowout patche mounting hole 4 distributing ringwise that is drilled with on upper blowout patche 2 and lower blowout patche 3, upper blowout patche 2, lower blowout patche 3 are by being connected into the overall blowout patche of a cross section for " work " font through the bolt of blowout patche mounting hole 4.
Between dividing on the annular protrusion upper surface of seat ring 1 and the top of overall blowout patche, raceway in twice is set, on this, raceway is angular contact ball bearing structure raceway near the inboard raceways of axis, in it, fill ball 5, in upper raceway, be thrust bearing raceway away from the outboard raceway of axis, in it, fill roller 6.
Between dividing in the annular protrusion lower surface of seat ring 1 and the bottom of overall blowout patche, raceway under twice is set, this lower raceway is angular contact ball bearing structure raceway near the inboard raceways of axis, in it, fill ball 7, in lower raceway, be thrust bearing raceway away from the outboard raceway of axis, in it, fill roller 8.
