Abstract
The utility model relates to the technical field of a gear seat, in particular to a car planetary gear seat. When an inner draft angle arranged by a lower gear and an upper gear of the car planetary gear seat is 25-35 degrees, a powder metallurgy technology is adopted to manufacture the planetary gear seat, so that the quality of the planetary gear seat can be ensured, and demoulding during production is favored. Meanwhile, the car planetary gear seat has the advantages of high production efficiency, low cost, long service life, simple structure, reasonable design and low manufacture cost.
Description
Technical field
The utility model relates to the pinion stand technical field, particularly a kind of vehicle planetary pinion stand.
Background technique
The Along with people's living standard improves constantly, and to the also constantly increase of demand of automobile, the cost performance of automobile is as a big standard of consumer choice, so the Cost And Performance of auto parts machinery is also constantly proposed new demand.
At present; Planetary gear construction more complicated on the automobile self-rescue tractor, in order to adapt to conventional mechanical processing technique, its next gear and upper gear adopt the right angle transition; But along with market demands change, shortcomings such as the cost height of conventional mechanical processing technology, manufacturability difference progressively come out.Powder metallurgy is to utilize existing scrap metal powder to push as raw material to sinter into, and the cost of material is low for it, and manufacturing process is simple.Replace the accessory of materials such as existing copper, aluminium, steel with powder metallurgy, can guarantee quality of product, can practice thrift cost again.But during powder metallurgy technology processing Planetary gear seat, the next gear and upper gear are still gone up the material capability of the next gear with right angle transition meeting influence, make troubles also can for the production demoulding.How to guarantee the material capability of the next gear, provide a kind of Planetary gear seat simple, that be prone to the demoulding to become the topic of studying in the auto parts machinery industry.
The model utility content
The purpose of the utility model is defective and the deficiency to existing technology, provides a kind of simple in structure, a kind of vehicle planetary pinion stand reasonable in design, easy to use.
For realizing above-mentioned purpose, the technological scheme that the utility model adopts is:
The described a kind of vehicle planetary pinion stand of the utility model, it comprises hollow base frame, pedestal wall, the next gear, upper gear and external gear, said the next gear and upper gear are arranged on the inwall of hollow base frame; Said external gear is arranged on the periphery of pedestal wall one end; Said the next gear and upper gear are provided with interior draft angle.
Further, interior draft angle the best is 25 °～35 °.
After adopting said structure, the utility model beneficial effect is: the described a kind of vehicle planetary pinion stand of the utility model, when the interior draft angle of its next gear and upper gear setting is 25 °～35 °; Adopt the powder metallurgy technology to make Planetary gear seat; Both can guarantee the quality of Planetary gear seat, be beneficial to the demoulding when producing again, also have manufacturing efficiency; Cost is low, the advantage of long service life.The utlity model has simple in structure, reasonable in design, low cost of manufacture.

Fig. 2 is an A place structure for amplifying schematic representation among Fig. 1.
Description of reference numerals:
1, hollow base frame; 2, pedestal wall; 21, the next gear;
22, upper gear; 23, external gear; α, interior draft angle.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the described a kind of vehicle planetary pinion stand of the utility model, it comprises hollow base frame 1, pedestal wall 2, the next gear 21, upper gear 22 and external gear 23, said the next gear 21 and upper gear 22 are arranged on the inwall of hollow base frame 1; Said external gear 23 is arranged on the periphery of pedestal wall 2 one ends; Draft angle α in said the next gear 21 is provided with upper gear 22.The setting of interior draft angle α both can guarantee that the density of Planetary gear seat cast form was even, demoulding during convenient again production.The vehicle planetary pinion stand is made and is adopted the powder metallurgy technology, can enhance productivity, and reduces production costs, and satisfies the demand in market.
Draft angle α the best is 25 °～35 ° in said, and interior draft angle α is the best angle of the complete demoulding between 25 °～35 °.
When adopting the powder metallurgy technology to make Planetary gear seat with the utility model, both can guarantee the quality of Planetary gear seat, and be beneficial to the demoulding when producing again, and also have manufacturing efficiency, cost is low, the advantage of long service life.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
Claims (2)
