Abstract
An integral retainer for a bidirectional thrust tapered roller bearing is provided with a set of closed pockets in a radial arrangement. The lower curved surface of each pocket is tangent to the rolling surface of the tapered roller to realize the function of accommodatingand guiding the tapered roller. An inclined surface protruding from both sides of the pocket is formed above each pocket, and the lower surface of the pocket is provided with a roller locking pressure groove. When a roller is installed in each pocket, the roller is pushed by contracting the roller locking pressure groove, and the roller is locked by the protruded inclined surface on the pocket by expanding the roller locking pressure groove. An arc oil groove is formed where the pocket and the chamfer of the roller contact. The retainer of the present invention has functions of oil storage for lubricating, reduces friction, and realizes pure rolling when a rolling body works. The integral retainer enhances the impact resistance performance of the bearing, guarantees the effect of flexible rotation of the bearing and prolongs the service lifetime of the bearing.
Description
Technical field
The present invention relates to bearing mnanufacture technical field, particularly relate to a kind of Integral retainer of bidirectional thrust tapered roller bearing.
Background technique
Bidirectional thrust tapered roller bearing structure is more complicated, and bearing capacity is strong, and can bear bi-directional axial load, good rigidly, and can withstand shocks load, for the retainer that this bearing is supporting also should be applicable to this kind of operating mode use.The traditional retainer of bidirectional thrust tapered roller bearing is solid cage seat and the retainer lid of separable, car, keep the pocket hole that stand has one group of aplysia punctata arrangement unlimited, serve the effect of maintenance and guide rolls, after roller loads maintenance stand, keep stand to be connected with retainer lid elastic cylindrical pin, retainer and roller achieve the function of whole assembly.But this structure is only applicable to general operating mode, and heavy duty cannot be ensured and have the bad working environments of impulsive load to use.Therefore to the retainer architecture advances of traditional bidirectional thrust tapered roller bearing, be the active demand of meeting the need of market.
Summary of the invention
The technical problem to be solved in the present invention is, provides one can ensure heavy duty and have impulsive load bad working environments to use, a kind of Integral retainer of the bidirectional thrust tapered roller bearing of extensively meeting the need of market.
The technological scheme adopted is:
A kind of Integral retainer of bidirectional thrust tapered roller bearing, be provided with the pocket hole that the arrangement of one group of aplysia punctata is closed, the lower surface camber in described pocket hole is tangent with the rolling surface of tapered roller, serves and contains and the effect of guide rolls.Be provided with to protrusion plane of inclination, both sides, pocket hole above described pocket hole, be provided with lock roller indent below relative pocket hole, when loading roller to pocket hole, shrink press-in roller by lock roller indent, by expanding lock roller indent, the protrusion plane of inclination above pocket hole is made to pin roller.Described pocket hole and roller chamfer contacting point are set as circular arc oil duct.
Above-mentioned pocket outer end of hole and inner retainer are equipped with oily nest.
The present invention adopts retainer and roller to carry out whole assembly, and pocket hole and roller chamfer contacting point are carried out circular arc oil duct and retainer and to be oiled nest, and serve trapped fuel lubrication, reduce friction and hinder, can realize rolling element is operationally pure rolling.This kind of Integral retainer, enhances the shock proof performance of bearing, ensure that bearing rotary effect flexibly, extends the working life of bearing.

Embodiment
A kind of Integral retainer of bidirectional thrust tapered roller bearing, is provided with the pocket hole 3(that the arrangement of one group of aplysia punctata closes and sees Fig. 3), the lower surface camber in described pocket hole is tangent with the rolling surface of tapered roller, serves and contains and the effect of guide rolls.Be provided with to protrusion plane of inclination 5, both sides, pocket hole (see Fig. 4, Fig. 5) above described pocket hole 3, be provided with lock roller indent 6(below relative pocket hole and see Fig. 6, Fig. 7), when loading roller 2 to pocket hole, press-in roller is shunk by lock roller indent 6, by expanding lock roller indent 6, make the protrusion plane of inclination 5 above pocket hole pin roller, retainer and roller achieve the function (see figure 1) of whole assembly.Described pocket hole 3 is set as circular arc oil duct 7 with roller 2 chamfer contact place, and outer end, pocket hole 3 and inner retainer 1 are equipped with oily nest 4, serves trapped fuel lubrication, and reduce friction and hinder, can realize rolling element is operationally pure rolling.This kind of Integral retainer, enhances the shock proof performance of bearing, ensure that bearing rotary effect flexibly, realizes the highi degree of accuracy rotated.
