Abstract

The present invention relates to a kind of rear-end gear reduction bearing, category automobile axle component technology field.The bearing includes bearing block, bearing inner race, bearing outer ring, roller and retainer；Bearing inner race and bearing outer ring are installed in bearing block, roller is provided with by retainer symmetry shape between bearing inner race and bearing outer ring；Bearing block oil filler point and pilot hole are provided with described bearing block.The bearing arrangement is simple, and practicality is good, and the outer ring of the bearing is overall structure, instead of the Split type structure of original bearing, and has subtracted the gear platform in the middle of original bearing, thus optimizes structure；The inner ring A and inner ring B that bearing inner race is respectively L-type by section are constituted, and are brought into close contact connection between the two, have subtracted the center spacer of original bearing, clearance is adjusted from there through two inner rings, parts is reduced, production cost is both reduced, installation process is simplified again.

Description

A kind of rear-end gear reduction bearing

Technical field

The present invention relates to a kind of rear-end gear reduction bearing, category automobile axle component technology field.

Background technology

The main speed reduction bearing of current automobile axle is symmetrically to be mounted in bearing using two identical standard taper roll bearings In seat, due to placing a spacer ring between two bearing inner races, so necessarily cause adjustment bearing axial clearance adjustment complicated, dress Replace the spare parts many, make overall relatively costly.

The content of the invention

It is an object of the invention to provide a kind of simple structure, practicality is good, the back axle master for facilitating gap to adjust and assemble Decelerator bearing.

The technical scheme is that：

A kind of rear-end gear reduction bearing, including bearing block, bearing inner race, bearing outer ring, roller and retainer；Its feature exists In：Bearing inner race and bearing outer ring are installed in bearing block, are set by retainer symmetry shape between bearing inner race and bearing outer ring It is equipped with roller；Bearing block oil filler point and pilot hole are provided with described bearing block.

Described roller is pyramid type.

Outer ring corresponding with bearing block oil filler point oil filler point is provided with described bearing outer ring.

Described bearing outer ring section is tapered.

Described bearing inner race is split type, and bearing inner race is made up of inner ring A and inner ring B, the section of inner ring A and inner ring B Respectively L-type, is brought into close contact connection between inner ring A and inner ring B.

Inner convex platform is provided with the port of described bearing block side, inner convex platform is connected with bearing outer ring contact.

The beneficial effects of the present invention are：

The rear-end gear reduction bearing arrangement is simple, and practicality is good, and the outer ring of the bearing is overall structure, instead of original bearing Split type structure, and the gear platform in the middle of original bearing has been subtracted, thus optimize structure；Bearing inner race is respectively L-type by section Inner ring A and inner ring B is constituted, and is brought into close contact connection between the two, the center spacer of original bearing has been subtracted, from there through two Inner ring adjusts clearance, reduces parts, both reduces production cost, and installation process is simplified again.

Specific embodiment

The rear-end gear reduction bearing includes bearing block 1, bearing inner race, bearing outer ring 2, roller 3 and retainer 4；Bearing Bearing inner race and bearing outer ring 2 are installed in seat 1, bearing block oil filler point 5 and pilot hole 6 are provided with bearing block 1.Bearing outer ring 2 sections are tapered；Outer ring corresponding with bearing block oil filler point 5 oil filler point 7 is provided with bearing outer ring 2.

Conical roller 3 is provided with by the symmetry shape of retainer 4 between bearing inner race and bearing outer ring 2；Bearing inner race For split type, bearing inner race is made up of inner ring A8 and inner ring B9, and the section of inner ring A8 and inner ring B9 is respectively L-type, inner ring A8 and Connection is brought into close contact between inner ring B9.By the close contact of inner ring between inner ring A8 and inner ring B9, it is possible to achieve the axle of bearing To clearance self-regulated；And then improve the life-span of bearing.

Inner convex platform 10, inner convex platform 10 and bearing are provided with the port of the side of bearing block 1 of the rear-end gear reduction bearing The contact connection of outer ring 2, the purpose of inner convex platform 10 is to avoid outer ring to slide at work.

The rear-end gear reduction bearing arrangement is simple, and practicality is good, and the bearing outer ring 2 of the bearing is overall structure, instead of The Split type structure of original bearing, and subtracted the gear platform in the middle of original bearing, thus optimize structure；Bearing inner race is by section Respectively the inner ring A8 and inner ring B9 of L-type are constituted, and are brought into close contact connection between the two, have subtracted the middle interval of original bearing Circle, clearance self-regulated is realized from there through two inner rings, reduces parts, both reduces production cost, be in turn simplify Installation process；Production efficiency is improve simultaneously, production cost is reduced.
