Abstract
The utility model discloses a planetary gear stand, which relates to the technical field of automobile parts. The utility model is a planetary gear stand which can be manufactured by powder metallurgy technology with equal forming concentration and long service life. The utility model comprises a hollow gear stand, an upper tooth and a lower tooth in the gear stand, and an edge outer tooth at one end of the outside of the gear stand. The utility model is characterized in that a chamfer transition is adopted between the lower tooth and the upper tooth. Compared with the prior art, the utility model has the advantages that as the chamfer transition is adopted between the lower tooth and the upper tooth, the powder metallurgy technology can be adopted for pressing; the technology is good for a complete mould-release; the shaping concentration of the planetary gear stand can be equal; the manufacturing efficiency is high while the cost is low; and the service life is longer.
Description
Technical field
The utility model relates to a kind of technical field of auto parts and components, especially refers to the technical field of the Planetary gear seat on a kind of automobile self-rescue tractor.
Background technique
Planetary pinion is as the critical component on the automobile self-rescue tractor, because its structure more complicated, in order to be fit to conventional manufacturing technology, usually adopt the right angle transition between its upper tooth and the next tooth, but development along with manufacturing process, conventional manufacturing technology is because the manufacture cost height, defectives such as manufacturability difference, do not satisfied the demand of modern production development, and powder metallurgy can solve the defective of this part manufacturing process, but between upper tooth and the next tooth if still adopt the right angle transition, can be last, cause very big density difference between the lower tooth, and shorten the working life of the next tooth.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of can adopt that means of a powder metallurgy technique is made, shaping density evenly, the Planetary gear seat of long service life.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this Planetary gear seat comprises pedestal, the upper tooth and the next tooth in the pedestal of hollow and the peripheral external tooth that is positioned at the outer end of pedestal, it is characterized in that chamfering transition between described the next tooth and the upper tooth.
Described chamfer angle is 32 °.
Compared with prior art, advantage of the present utility model is: owing to adopt the chamfering transition between the next tooth and the upper tooth, can adopt powder metallurgical technique to suppress, help the complete demoulding, and can make the shaping density of Planetary gear seat even, and the manufacturing efficiency height, cost is low, and longer service life.
