Abstract

The utility model discloses a kind of high speeds without rib circular cone hub bearing, including outer ring, sealing ring inner ring, roller, mandrel, retainer, gear ring, sensor and bolt；The inner ring includes three, respectively inner ring I, inner ring II and inner ring III, and the roller is that Double-conical-surface roller, the inner ring I and inner ring II are connected with the matching of side roller, and the inner ring III is connected with the matching of other side roller.The roller designs of the utility model are Double-conical-surface, can avoid axial thrust when lateral loading force, do not redesign rib to offset axial force, also not again can due to sliding friction earlier period damage.The hollow design of roller facilitates product group equipped with preloading, and does not have sliding friction in rotation process and destroys raceway face, making hub bearing, the service life is longer.

Description

A kind of high speed is without rib circular cone hub bearing

Technical field

The utility model relates to a kind of hub bearing assemblies, and in particular to a kind of high speed is without rib circular cone hub bearing.

Background technique

Currently, application of the circular cone hub bearing on automobile, due to the superiority of structure, so that the large carrying capacity of vehicle It is big to increase.Into manufacturing development over year, the performance and integrated, the peace on automotive wheel of circular cone hub bearing are constantly changed Dress is single-row from two, to a biserial, then to bearing block, wheel speed sensors is integrated, also saves the rotation riveting knot structure of nut, This all improvement makes the performance of automotive hub more superior, and manufacture and use are more convenient, replaces also more economical.

Circular cone hub bearing during processed, traditional design be inner ring have rib (as shown in Figure 4), optimal position it is lateral Thrust, contact of roller (as shown in Figure 5) end face with rib be sliding friction, over time, roller and inner ring friction generate High temperature makes roller and inner ring raceway that ablation occur, and then will appear fatigue damage, part also loses the function of rotation and carrying.

Summary of the invention

The technical problem to be solved by the utility model is to provide a kind of high speeds without rib circular cone hub bearing, roller designs For Double-conical-surface, axial thrust when lateral loading force can avoid, the hollow design of roller facilitates product group equipped with preloading, rotated Sliding friction is not had in journey and destroys raceway face, the service life is longer for hub bearing.

The utility model technical scheme applied to solve the technical problem is: a kind of high speed without rib circular cone hub bearing, Including outer ring, sealing ring inner ring, roller, mandrel, retainer, gear ring, sensor and bolt；The inner ring includes three, respectively For inner ring I, inner ring II and inner ring III, the roller is Double-conical-surface roller, and the inner ring I and inner ring II match rank with side roller It connects, the inner ring III is connected with the matching of other side roller.

As a preference, the gear ring is set between inner ring II and inner ring III.

The beneficial effects of the utility model are: roller designs are Double-conical-surface, axial thrust when lateral loading force can avoid, Do not redesign rib to offset axial force, also not again can due to sliding friction earlier period damage.The hollow design of roller helps to produce Product be assembled with it is preloading, do not had in rotation process sliding friction destroy raceway face, making hub bearing, the service life is longer.

Specific embodiment

In conjunction with shown in attached drawing 1~3, a kind of high speed is without rib circular cone hub bearing, including outer ring 1,2 inner ring of sealing ring, rolling Son 3, mandrel 4, retainer 6, gear ring 7, sensor 8 and bolt 9；The inner ring includes three, respectively inner ring I 5, inner ring II 10 With inner ring III 11, the roller 3 is that Double-conical-surface roller, the inner ring I 5 and inner ring II 10 are connected with the matching of side roller 3, described Inner ring III 11 is connected with the matching of other side roller 3.The gear ring 7 is set between inner ring II 10 and inner ring III 11.Sealing ring 2 Prevent dust, sundries, muddy water etc. from entering inside hub-bearing unit.Bolt 9 connects wheel rim.

Wherein outer ring 1 connects automobile chassis；Sealing ring 2, seal grease is excessive, and the dust for being also prevented from outside enters raceway； Double-conical-surface roller 3, the weight of rotation and carrying vehicle；Mandrel 4, connection wheel and transfer of torque；Inner ring I 5, inner ring II 10, inner ring III 11, the raceway of support roller rotation；Retainer 6, guide rolls rotation, constrains roller position；Gear ring 7, wheel rotation speed signals Generator；Sensor 8, wheel speed measuring cell；Bolt 9, fixing vehicle wheel.

Working principle are as follows: Double-conical-surface roller is set by the stress of two conical surfaces come optimal position play to save inner ring Count rib limitation roller (as shown in figure 4, wherein 12 be inner ring, 13 be rib, and 14 be roller).Hollow roller can bear a certain amount of Preload, effectively prevent roller slip, design in this way can improve the service life of hub bearing.
