Description
Technical field
This utility model relates to a kind of variator two axle assembly bearing block, is specifically related to a kind of axial limiting needle bearing seat.
Background technology
Single middle-shaft automotive speed-variator two axle assembly often structure is complicated, and part is many, equipped with needle bearing between gear and two axles.
In order to the many parts on two axles being carried out axial limiting, often two axles being designed to centre is the thickest, is gradually become to two ends by centre
Thin Step Shaft form, by the shaft shoulder and coordinate needle bearing seat, back-up ring, snap ring etc. to carry out spacing to the part on two axles, real
Now install and use function.For big centre-to-centre spacing variator, variator two axle is relatively thick, can be by the shaft shoulder pair of certain altitude
Part on two axles carries out axial limiting.But in the case of, centre-to-centre spacing more at transmission gear is less, by variator center
Away from restriction, the diameter of axle can not be too thick, and the spring bearing at axle two ends can not be the least, therefore cannot design abundant on axle
Step carries out the axial location of part, and by installing back-up ring, snap ring etc. on axle, the part on two axles must be carried out spacing
Can effectively realize installing and using function.Thus make parts on shaft quantity increase, and each part all have mismachining tolerance,
The error accumulation of multiple parts gets up to make the part positioning precision on whole axle to reduce, and additionally part is the most, between part
Contact surface is the most, and frictional impact face is the most, and the noise of generation is the biggest.
Utility model content
The purpose of this utility model is for above-mentioned defect of the prior art, it is provided that a kind of simple in construction, easy for installation, fixed
Position precision is high, it is possible to be effectively improved the axial limiting needle bearing seat of efficiency of assembling.
To achieve these goals, the technical solution adopted in the utility model is: include the bearing block body coordinated with two axles, axle
One end of bearing body is provided with the flange for two parts on shaft carry out axial limiting.
Described bearing block body is one-body molded with the flange of its end.
The oil-feed breach for the lubricating oil that circulates it is machined with in described flange outer periphery.
Described oil-feed breach is the multiple arc notch being uniformly opened in flange outer periphery.
Described oil-feed breach is two truncation breach that symmetry is opened in flange outer periphery.
Described thickness of flange >=2mm.
Described flange outside diameter is more than the diameter of bore of the installed part in flange both sides.
Compared with prior art, this utility model by one end of bearing block body design flange, it is possible to substitute common back-up ring with
And snap ring, be equivalent to be combined into back-up ring and bearing block one entirety, so more accurate to the location of two shaft gears and other part
Really, installation is the most convenient.Further, since typically installed by interference fit between bearing block and two axles, it is right to eliminate
Back-up ring carries out the design of spacing aspect and considers.Needle bearing seat of the present utility model has simple in construction, axial positioning precision height,
Good reliability, the plurality of advantages such as easy for installation, can effectively reduce by two axle assembly number of parts simultaneously, improve efficiency of assembling.
Further, thickness of flange >=2mm of the present utility model, thickness is too small can not meet part strength requirement.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Seeing Fig. 1, traditional needle bearing seat can not meet the positioning requirements installing part on axle, generally requires and arranges on axle
Two shaft gears and needle bearing etc. are carried out spacing by back-up ring and snap ring etc..
See Fig. 2,3, this utility model structurally includes and the bearing block body 1 of two axle interference fit, bearing block body 1
One end be provided with the flange 2 for two shaft gear end faces or other part being carried out axial limiting.Flange 2 visually uses on periphery
Situation processes several oil-feed breach 3 for the lubricating oil that circulates, for the needle roller axle being loaded on needle bearing seat during use
Offer lubrication is provided.This utility model substitutes spacing back-up ring by being set to the flange 2 of one with bearing block, is equivalent to back-up ring and axle
These 2 part combination of bearing become a part, so more accurate to the location of two shaft gears, install the most convenient.
Without relative motion between this utility model bearing block and two axles, therefore, this kind of design needs to examine without the concern for conventional design
The back-up ring location on two axles considered and anti-rotation, this kind of design simultaneously reduces number of parts, decreases between different part because of peace
The frictional impact that dress gap produces contacts with surface, it is possible to reduce the noise that variator produces because of frictional impact.
See Fig. 4, in order to the gear a on countershaft and gear b axially positions, common two axle assemblies are provided with bearing block,
The right side of gear a and the left side of gear b are carried out spacing by back-up ring 5 and snap ring 6 three parts altogether.See Fig. 5,
This utility model replaces the bearing block in Fig. 3, back-up ring 5 and snap ring 6, installs more convenient.Two axles in Fig. 4 and Fig. 3 simultaneously
In two axles compare, owing to need not install snap ring 6, the structure of axle is simpler, and processing cost is lower.
See Fig. 6, in order to gear a, b, the c on countershaft and needle bearing thereof carry out axial limiting, in traditional two axle assemblies respectively
It is provided with double common needle bearing seats and double back-up ring.See Fig. 7, this utility model replace two bearing blocks in Fig. 6 and
Two back-up rings 5, by a needle bearing seat with axial limit function, decrease part and install quantity, decrease part and add
Work error accumulation, improves the part positioning precision on axle, installs more convenient simultaneously, and cost is lower.
