Abstract
The utility model provides a differential mechanism, includes differential mechanism shell, planetary gear, planetary gear gasket and cross axle, its improvement lies in: the planetary gear gasket adopts thrust needle roller bearing. The utility model discloses an useful technological effect is: can guarantee planetary gear operation steady in a long -term.
Description
Technical field
This utility model is related to a kind of heavy-duty car differential mechanism, more particularly to a kind of Novel differential gear.
Background technology
There are multiple pads inside differential mechanism, wherein, related to this utility model is planet gear pad, and its effect is
Adjust the backlash between planetary gear and axle shaft gear and prevent planetary gear from rubbing with differential carrier inwall directly contact；
The problem of presence is：In prior art, planet gear pad typically adopts spherical pad, due to spherical pad and planetary gear and
The friction type of differential mechanism inwall is sliding friction, and frictional resistance is larger, and after life-time service, spherical pad abrasion is very tight
Weight, causes the backlash between planetary gear and axle shaft gear to become big, when serious, it may appear that beat tooth situation, damages differential mechanism.
Utility model content
For the problem in background technology, the utility model proposes a kind of Novel differential gear, including differential carrier, planet
Gear, planet gear pad and cross axle, the cross axle is arranged in differential carrier, and planetary gear and planet gear pad are equal
It is socketed on cross axle, planet gear pad is located between planetary gear outer face and differential carrier inwall, and it is improved by：Institute
State planet gear pad and adopt needle roller thrust bearing.
Planet gear pad is used instead after needle roller thrust bearing by original spherical pad, planet gear pad and surrounding structure
The friction type of body is also become for rolling friction by original sliding friction, and frictional resistance significantly reduces, and abrasion progress substantially subtracts
It is slow, it is ensured that planetary gear runs steadily in the long term.
Advantageous Effects of the present utility model are：Can guarantee that planetary gear runs steadily in the long term.
Description of the drawings
Fig. 1, structural representation of the present utility model；
Fig. 2, planet gear pad structural representation one of the present utility model；
Fig. 3, planet gear pad structural representation two of the present utility model；
Title in figure corresponding to each labelling is respectively：Differential carrier 1, planetary gear 2, planet gear pad 3, cross
Axle 4.
Specific embodiment
A kind of Novel differential gear, including differential carrier 1, planetary gear 2, planet gear pad 3 and cross axle 4, described ten
Word axle 4 is arranged in differential carrier 1, and planetary gear 2 and planet gear pad 3 are socketed on cross axle 4, planet gear pad
3 are located between the outer face of planetary gear 2 and the inwall of differential carrier 1, and it is improved by：The planet gear pad 3 adopts thrust
Needle bearing.
