Description
Technical field
The present invention relates to the element with teeth of the band for translatory movement, refers in particular to a kind of Rigid Gear of Harmonic Reducer new material and system
Make technique.
Background technology
Firm gear is one of three big core parts in harmonic speed reducer, and its structure is the hollow cylindrical tooth for having multiple internal tooths
Wheel, common used material has 45 at present#Steel, 40Cr, 20CrMo, 20CrMnTi etc., its processing technology are generally forged with rod iron or sheet material
Make, then pass through the technique machine-shapings such as machining, heat treatment, grinding.Processing charges is high, and waste of material is big, and heat treatment will
Ask high, it is not wear-resistant the shortcomings of.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of Rigid Gear of Harmonic Reducer new material and making
Technique.
The technical solution adopted for the present invention to solve the technical problems is：A kind of Rigid Gear of Harmonic Reducer new material is provided,
It is characterized in that the material includes following components in weight percent：Carbon 1.5~2.5, manganese 0.12~0.4, nickel≤0.03, silicon
0.1~0.8, silicon 0.05~0.25, calcium 0.2~1.6, chromium≤0.03, copper 1.5~3.2, surplus are iron.
Further, the present invention provides a kind of manufacturing process of Rigid Gear of Harmonic Reducer new material, it is characterised in that including
The following steps performed successively：The producing of powder, the mixing, be compressing of powder pre-treating, powder materials, sintering, heat treatment, machine
Tool processing, tooth Profile Machining, the powder pre-treating include：Annealing, screening, granulation, first make annealing treatment various metal dusts,
Annealing temperature is different according to the species of various metal dusts, usually 0.5~0.6K of melting point metal, the annealing of usual copper powder
320 DEG C of temperature, iron powder for 680 DEG C.Annealing reducibility gas, it is incubated 1.5~3.5h, then furnace cooling；The powder
The mixing of material is that the metal dust is proportionally added into ball mill, and it is uniform to add a certain amount of stearate material mixing, institute
It is that mixed metal dust material is put into pre-manufactured pressing mold to suppress to state compressing, room temperature compacting, 1 ton of pressurization/
Pressure more than square centimeter.
Porous, half fine and close or full dense material and product, harmonic speed reducer can be directly prepared into PM technique
Firm gear blank powder metallurgically manufacturing can reduce materials, machining be reduced, so as to reduce processing cost, while powder smelting
Gold utensil has the chemical composition and machinery, physical property of uniqueness, and these performances can not be obtained with traditional casting method.
The beneficial effects of the invention are as follows：Save material, easy processing, cost is low, finished product is made has self-lubricating, wearability
It is excellent, the features such as gearing noise is small, harmonic speed reducer service life is greatly improved.Than the material wear ability used at present
More than 30% is improved, for material cost also than the material economy more than 30% used at present, it is left that the total physical efficiency of processing cost reduces by 25%
It is right.
