Abstract
The invention discloses a manufacture method of a special gear plate, which comprises the steps: dividing the special gear plate into a gear and a flange plate, sintering and carburizing the gear and the flange plate, and integrally pressing and fitting the gear and the flange plate. The manufacture method of the special gear plate is easy to manufacture and operate, is good for saving the cost, and is high in the manufacture efficiency, i.e. the products of 3500PCS can be manufactured every 8 hours. Furthermore, the manufacture method is low in manufacture cost, high in product precision, good in economic prospect, and good in social benefit.
Description
Technical field
The present invention relates to a kind of preparation method of toothed disc, be specifically related to a kind of preparation method of special gear dish.
Background technology
Powder metallurgy toothed wheel disc production method is generally finished by operations such as shaping, sintering, heat treatment, last items, but for the inboard internal diameter of upper flanges dish aperture during less than lower end gear teeth portion external diameter, be Φ B＜Φ A, as shown in Figure 1, normal operation can not satisfy the making requirement, under many circumstances, take flange shaping thickening, through hole are made blind hole, by follow-up mechanical process, so both increased raw material and cost of manufacture, production efficiency is also very low.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the purpose of this invention is to provide a kind of preparation method of special gear dish, to realize being easy to production operation, to be beneficial to and to save cost, efficient height, product precision height.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution used in the present invention is as follows:
A kind of preparation method of special gear dish by the special gear dish being divided into two parts of gear and ring flange, carries out sintering and carburizing operation to gear and ring flange respectively, then gear and ring flange is press-fitted in aggregates getting final product.
Described gear and ring flange are made by the powder metallurgy raw material of following parts by weight: Fe:86.0～98.0 part, C:0～1.0 part, Ni:1.0～7.0 part, Mo:0～1.0 part, Cu:1.0～5.0 part.
The inboard internal diameter of the upper flanges dish aperture of described special gear dish is less than lower end gear teeth portion external diameter.
Beneficial effect: the preparation method of special gear dish of the present invention, be easy to production operation, be beneficial to the saving cost, the production efficiency height, every 8H can produce the 3500PCS goods, and production cost is low, product precision height, have good economic outlook, can produce good social benefit.
