Prior art
General turntable bearing is axially a kind of and radial cylinder set of rollers sympodium holds, and completely fills centripetal roller bearing combine by two cylindrical roller thrust bearings and one.But this bearing structure is complicated, difficulty of processing is large, and cost of production is high, and rotating speed is low.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of high speed turntable bearing, to reach simplified structure, to reduce costs and put forward high-revolving object.
The utility model is achieved in that
High speed turntable bearing completely fills radial ball bearing by a cylindrical roller thrust bearing and one and combines, described cylindrical roller thrust bearing is combined into by outer ring and blowout patche, retainer and a row cylinder roller, and described cylindrical roller is assemblied between the axial end of described outer ring and described blowout patche by retainer; The described radial ball bearing that completely fills is made up of outer ring and inner ring, stopper, taper pin and radial ball, radially plug hole is offered in described outer ring, described stopper is installed in described plug hole, has axial taper pin-hole and be provided with the taper pin that stopper can be made to locate in the arranged outside of described plug hole; The end face that described outer ring, described stopper are relative all has ball groove, for assembling one group of radial ball, the corresponding position of described blowout patche and described inner ring having attachment hole and by cross-under set screw, described blowout patche is fixed on the axial end of described inner ring.
Be provided with uniform through hole vertically in described outer ring, be divided into fixed via and tapped hole in described through hole, interval is arranged, and described fixed via is used for fixing outer ring, and described tapped hole is for lifting by crane turntable bearing.
The center of the exterior edge face of described stopper 9 is provided with tapped hole, for dismantling stopper.
Owing to have employed technological scheme described above, the utility model has following beneficial effect:
1, cylindrical roller of the present utility model can bear larger thrust load, and radial ball can bear larger radial load and tilting moment.
2, outer ring adopts plug hole, can install larger steel ball, improve the rigidity of bearing.
3, more general turntable bearing, the utility model has that structure is simple, cost of production is low and rotating speed advantages of higher, is specially adapted to high-speed vertical revolving table or the index plate of lathe or other precision optical machineries.

In figure: 1-outer ring; 2-cylindrical roller; 3-blowout patche; 4-inner ring; 5-set screw; 6-radial ball; 7-retainer; 8-taper pin; 9-stopper; 10-through hole.
Embodiment
As shown in Figure 1, high speed turntable bearing of the present utility model, completely fills radial ball bearing by a cylindrical roller thrust bearing and one and combines.
Cylindrical roller thrust bearing is combined by outer ring 1 and blowout patche 3, retainer 7 and a row cylinder roller 2.Cylindrical roller 2 is assemblied between the axial end of outer ring 1 and the axial end of blowout patche 3 by retainer 7.Completely fill radial ball bearing to be made up of outer ring 1 and inner ring 4, stopper 9, taper pin 8 and radial ball 6.Radially offer plug hole in outer ring 4, stopper 9 is installed in this plug hole.The center of the exterior edge face of stopper 9 is provided with tapped hole, for dismantling stopper.
There is axial taper pin-hole in the arranged outside of this plug hole and the taper pin 6 that stopper can be made to locate is installed.The end face that outer ring 1, stopper 9 are relative all has ball groove, for assembling one group of radial ball 6.The corresponding position of blowout patche 3 and inner ring 4 has attachment hole and by cross-under set screw 5, described blowout patche 3 is fixed on the axial end of described inner ring 1, the attachment hole on inner ring 4 is stepped throughhole.By blowout patche 3 and inner ring 4 fixedly make cylindrical roller thrust bearing and completely fill radial ball bearing be fixed together and form this high speed turntable bearing.
This high speed turntable bearing is provided with uniform through hole 10 vertically in described outer ring, and this through hole 10 is divided into fixed via and tapped hole, and interval is arranged.Fixed via is used for fixing outer ring, and tapped hole is for lifting by crane turntable bearing.
In the utility model, the width of inner ring 4 is the width of described outer ring 1 and the diameter sum of cylindrical roller 2.The internal diameter of blowout patche 3 is slightly larger than the internal diameter of inner ring 4.The external diameter of blowout patche 3 is slightly larger than the external diameter of retainer 7.At the through hole 10 that the axial end of blowout patche 3 is arranged, the diameter of the central diameter of tapped through hole wherein and the fixed via of circumference uniform distribution is equal with the end face diameter macropores of the stepped connecting through hole of inner ring 4, the straight hole diameter of this blowout patche 3 is equal with the end diameter of the stepped connecting through hole of inner ring 4, this tapped through hole arrange the straight hole of number and blowout patche 3 arrange number sum and described inner ring 4 stepped throughhole to arrange number equal.
In bearing working process, outer ring 1, inner ring 4 and blowout patche 3 drive radial ball 6 to rotate around bearing axis together with retainer 7 with cylindrical roller 2 respectively, and radial ball 6 and cylindrical roller 2 had not only revolved round the sun but also rotation in bearing rotary process.Cylindrical roller thrust bearing in the utility model can bear larger thrust load, completely fills radial ball bearing and can bear larger radial load and tilting moment.
