Description
Technical field
The invention belongs to field of bearings, is related to a kind of hub reduction gear thrust bearing.
Background technology
Hub reduction gear is afterbody deceleration torsion increasing device in automotive transmission, can be met total using hub reduction gear
Gearratio under the same conditions, reduces the load of the parts such as speed changer, power transmission shaft, main reducing gear, differential mechanism, semiaxis, size
The advantages that diminishing and making drive axle obtain the larger road clearance, it is widely used in load truck, motorbus, cross-country
Automobile and some other large-scale work mine car.Therefore the research to hub reduction gear, has critically important practical significance and enterprise
Practicality.
Sun gear in existing hub reduction gear, planetary gear both sides are pads in the market, during running car, when
When planetary gear and sun gear rotate, pad is also and then rotated, and cunning can be produced between pad and gear, pad and reducing gearbox
Dynamic friction, sliding friction now is produced between planetary gear, sun gear, pad, reducing gearbox, sliding recess can be produced, cause to go
Star-wheel, sun gear, pad, reducing gearbox inordinate wear and fail.A kind of new structure is needed now is ground extremely to solve this
Damage and Problem of Failure.
The content of the invention
The present invention is in order to make up the deficiencies in the prior art, there is provided a kind of energy-conservation, long-life, inseparable hub reduction
Device thrust bearing.
The present invention is achieved through the following technical solutions：
The hub reduction gear thrust bearing of the present invention, it is characterised in that：Blowout patche, seat ring and rolling including interconnection
Body, there is upward flange on the inside of blowout patche, have downward flange on the outside of seat ring, blowout patche, seat ring are formed by way of riveted
One closing box, rolling element is locked in closing box.
Retainer is also accompanied between blowout patche and seat ring, be evenly arranged with retainer several spaces be used for accommodate rolling
Body.
The lower edge of the flange of seat ring is provided with several riveted points, and riveted point forms inside projection；The flange of blowout patche
Top edge is provided with several riveted points, and riveted point forms outside projection；The projection of seat ring is stuck in the outer lower portion of retainer, axle
The projection of circle blocks the inside upper part of retainer, the bearing is separated.
Retainer is provided with centre circle big groove, outer ring little groove and inner ring little groove, the shaft section of retainer is formed W
Shape, is provided for separating the space of rolling element at centre circle big groove, and outer ring little groove and inner ring little groove are used to increase intensity.
The shaft section of blowout patche is L-shaped, and the shaft section of seat ring is in inverted L-shaped, and the two split forms square shape.
Rolling element uses needle roller, i.e. the bearing uses needle roller thrust bearing.
Blowout patche, seat ring are respectively adopted punching press and are made.
Retainer is made of punching press.
It is used for the space for accommodating rolling element on retainer, the opening of the upper surface in the space and the opening difference of lower surface are small
In the diameter of rolling element.
The invention has the advantages that the pad on hub reduction gear gear both sides is by punching press cell type needle roller thrust bearing generation
Replace, sliding friction is replaced by rolling friction, greatly reduce frictional force, needle roller thrust bearing is by two punched outer housings and one group of needle roller
Retainer is formed, and cages for needle component is locked between two lassos.During running car, planetary gear and sun gear rotation and band
Dynamic lasso rotation, this lasso drive cages for needle rotation, and needle roller is made to roll operating in a cell type raceway, slowed down
Relative motion is not produced between device shell and another matched lasso.So only have cages for needle to exist in running car
Make rolling movement between two lassos, and do not produce relative motion between lasso and reducing gearbox, planetary gear, sun gear, solve
Planetary gear, sun gear, pad, reducing gearbox inordinate wear and the problem of fail.Make the longevity of planetary gear, sun gear, reducing gearbox
Life improves 10 times, reduces maintenance cost and the man-hour of hub reduction gear.
Brief description of the drawings
Fig. 1 is the overall schematic of the present invention.Fig. 2 is close-up schematic view.Fig. 3 is that retainer along the circumferential direction deploys
Partial schematic diagram afterwards.
It is 1 seat ring, 2 blowout patches, 3 downward flange, 4 needle rollers, 5 upward flange, 6 riveted points, 7 retainers, 8 inside convex
