Description
Technical field
It the utility model is related to a kind of cone bearing master and subtract assembly, relate generally to main reducing gear field.
Background technology
The mechanism that main reducing gear can change torque and rotating speed in drive axle.Basic training be by from speed changer or
The torque increase of person's universal driving device, while reduce rotating speed and change the direction of transfer of torque.
A kind of integral type main cone bearing unit structure is disclosed in the patent document of Application No. 201320731646.8
Master subtract assembly, it includes main subtracting housing, drive bevel gear, active conical tooth wheel support bearing, bearing block, bead assembly, left and right
Differential mechanism and driven wheel of differential assembly, left and right differential mechanism include with driven wheel of differential assembly：Taper roll bearing, adjusting nut,
Locking plate, locking nut, spring washer, left and right differential case assembly, bolt, pad, planetary gear, cross axle, pad, axle shaft gear,
Driven wheel of differential, guide bearing, bolt, nut, bolt, wherein left and right differential case assembly are fixed on master and subtract housing, left and right
Differential case assembly outboard end is respectively fitting into master and subtracted in the fixing hole of housing or so, and fixing hole is as bearing block, due to this
For class main reducing gear using taper roll bearing, rigging error is larger, therefore existing solution is fixing hole as footpath
To fixing point, axial fixing point uses locking nut, and locking nut coordinates on the outside of fixing hole, then inwardly to tapered shaft
Hold and locked, and then overcome rigging error.This mode must utilize the regulation of locking nut and then control taper roller axle
That holds is elastic, manually adjusts entirely, can not realize accurate control, and colleague's structure is excessively complicated, easily occurs when use small
Failure.
Utility model content
For above the deficiencies in the prior art, the cone bearing for improving efficiency of assembling is simplified the utility model proposes a kind of structure
Master subtracts assembly.
To reach above-mentioned purpose, the technical solution of the utility model is：Subtract housing, drive bevel gear, left and right difference including master
Fast device housing assy and taper roll bearing, the main both ends for subtracting housing are respectively equipped with bearing fixing hole, set in bearing fixing hole inwall
There is ring shaped axial fixed seat, the left and right extension of left and right differential case assembly is provided with bearing fixing end, in bearing fixing end periphery
Left and right differential case assembly is provided with axial restraint platform, and taper roll bearing includes cone, cup and circular cone rolling
Son, cone are fixed on bearing fixing end excircle, the bearing between the inner end and axial restraint platform of cone
Annular gasket is cased with fixing end, the excircle of cup is fixed in bearing fixing hole, the outer end of cup and ring
Shape axial restraint seat is offseted, and taper roller is arranged between cone and cup.
Technical principle of the present utility model and have the beneficial effect that：Using this programme, relatively existing technology eliminates lock
Tight nut, caused rigging error is overcome using pad, structure is more simplified.When assembling, subtract the toughness of housing using master,
Rigging position is suitably expanded a bit, taper roll bearing and left and right differential case assembly are then stuck in centre, pad overcomes
Error caused by assembling.
Further, if pad includes dry plate rubber sheet gasket, can adjust pad as needed quantity, and then assembling is missed
Difference control is in minimum.
Brief description of the drawings

Embodiment
As shown in figure 1, the utility model includes, including master subtracts housing, drive bevel gear, left and right differential case assembly and circle
Taper roller bearing, drive bevel gear are fixed on the bottom of axle journal, and two active conical tooth wheel support bearings are fixed on shape on axle journal
Into main cone bearing unit.Main cone bearing unit is vertically arranged in the main top subtracted in housing, and subtracting the bottom in housing in master is provided with
Left and right differential case assembly, left and right differential case assembly includes, planetary gear, cross axle, axle shaft gear, driven wheel of differential, with
Upper is existing known technology.
Left and right differential case assembly is fixed on master by taper roll bearing and subtracted in housing, as shown in figure 3, master subtracts housing
Both ends are respectively equipped with bearing fixing hole, and ring shaped axial fixed seat is provided with bearing fixing hole inwall, left and right differential case assembly
Left and right extension is provided with bearing fixing end, and axial restraint platform is provided with the left and right differential case assembly of bearing fixing end periphery,
Axial restraint platform is set in main subtract on housing in advance, is adjusted without the later stage, therefore its precision is fixed, as shown in Fig. 2 circular cone
Roller bearing includes cone, cup and taper roller, and cone is fixed on bearing fixing end excircle, circular cone
Some annular gaskets, the excircle of cup are cased with bearing fixing end between the inner end and axial restraint platform of inner ring
It is fixed in bearing fixing hole, outer end and the ring shaped axial fixed seat of cup are offseted, and taper roller is arranged in circular cone
Between circle and cup.The axial direction of taper roll bearing is determined by axial restraint platform and ring shaped axial fixed seat
Position, and then ensure that cone and cup can be close together, while annular gasket is used, overcome its rigging error.
Overall structure is more simplified.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
