Description
Technical field
The present invention relates to a kind of material and making method, particularly a kind of making method of making the type material and the worm gear of worm gear.
Background technology
Worm gear is the common part of mechanical rotation, the material that is used for producing worm gear must possess good frictional behaviour and mechanical property, making the optimal material of worm gear at present is tinbronze, tinbronze belongs to non-ferrous metal, resource scarcity, cost an arm and a leg, a large amount of uses not only can increase the worm gear cost, also are unfavorable for Sustainable development.
Summary of the invention
The technical problem that the present invention solves is, solve existing worm gear manufacturing cost height, utilize tinbronze to be unfavorable for the problem of Sustainable development in a large number, provide a kind of worm gear cost of manufacture low, and the every well behaved type material of the worm gear of producing reaches the method for being made worm gear by this type material.
Technical scheme of the present invention is: a kind of type material of making worm gear, form by following component by mass percent: and powdered alloy 8-12%, graphite 0.6-1%, surplus is an iron; Powdered alloy is made up of following component by mass percent: tin 8-12%, and plumbous 4-7%, zinc 2-5%, nickel 6-10%, surplus is a copper.
A kind of method of making worm gear by above-mentioned type material comprises the steps:
A) produce powdered alloy by the recipe ingredient ratio, powdered alloy granularity 180-220 order, the fusing point of alloy is 900-1100 ℃;
B) powdered alloy that the first step is obtained and iron powder, graphite mix by ratio of component;
C) go on foot mixed powder according to the compression moulding in mould of worm gear dimensional requirement with second, pressed density is a 6.6-7.2 gram/cubic centimetre;
D) with pressed compact sintering in sintering oven, between 200-400 ℃ sintering 1.5-2.5 hour, between 400-900 ℃ sintering 1.5-2.5 hour, between 900-1200 ℃ sintering 2.5-3.5 hour, before coming out of the stove in 200-300 ℃ of timeliness 2.5-3.5 hour;
E) blank that previous step is obtained is done the vacuum oil immersion processing after being processed into worm gear.
The first step alloying powder of the present invention adopts Metal Melting and powder-making technique.
The invention has the beneficial effects as follows, powdered alloy among the present invention is a kind of material with good antifriction performance, in sintering process, progressively melt and wrap and be attached to around the iron particle, various elements in the alloy form new alloy in high temperature and liquid lower section and iron, and another part has still kept with the form of former alloy, one deck antifriction matter that is formed uniformly, make it under friction environment, play good lubricated appointing, simultaneously because body portion is a ferrous alloy, thereby guaranteed the overall mechanical properties of material, the worm gear of producing is functional.The present invention has reduced the use of tinbronze, has reduced cost of manufacture, utilizes Sustainable development, has broad application prospects.
