Abstract
The utility model relates to a steel base wear-resisting double-metal worm wheel which is composed of a worm wheel body and a worm wheel tooth. The utility model is characterized in that the worm wheel tooth is compounded by steel and copper alloy, or the steel and aluminum alloy. The utility model has the advantages of simple process, low cost, small size, reliable quality, long service life, a large amount of copper material saving, etc.
Description
The mechanical parts worm gear of domestic designed manufacturing at present, being single antifriction metal material forms, during as heavy duty or impulsive load, valuable antifriction material cast bronze alloy commonly used is made the worm gear material, because worm tooth is continuous helical tooth, and the intensity of worm screw material generally is higher than the worm gear material in worm drive.So, rippling, break of gear tooth, failure mode such as tooth surface abrasion and gummed mostly occurs on the worm gear gear teeth, so just require the worm gear gear teeth should have enough intensity, the favorable manufacturability energy, anti-attrition and wear resistance, material such as aluminum alloy commonly used, though reasonable anti-attrition is arranged, but its hardness is low, low and the temperature and pressure poor performance of intensity, can only be used in stablize shock-free underloading and in carry, and the cast bronze alloy, anti-attrition is good, but its temperature and pressure, intensity is many than the steel part difference all, especially casting defect, often cause reduction in strength, safety coefficient reduces, and difficult quality is reliably guaranteed, in heavy duty, when overload and sizable impulsive load, have to guarantee sufficient intensity to amplify, consume a large amount of noble metals, product cost is increased substantially.In order to address this problem, the integral cast of employing formula is also arranged in mechanical industry at present, larger-size worm gear, in order to save noble metal, structural types such as the gear ring type of employing, Bolt Connection formula, assembly casting formula are also arranged, though can save the part noble metal, but still have complex process, problems such as cost height.
The purpose of this utility model, just be to overcome the deficiencies in the prior art, provide that a kind of technology is simple, cost is low, intensity is high, anti-attrition, wear resistance be good, meets or exceeds former complete copper requirement working life fully, can save the base steel abrasion-proof duplex metal worm gear of a large amount of noble metals.
The purpose of this utility model realizes in the following way:
This base steel abrasion-proof duplex metal worm gear is made up of worm wheel body, worm-gear tooth, it is characterized in that, worm-gear tooth is to be formed by steel and Cuprum alloy or steel and aluminium alloy compound.
Also available other anti-attrition of described worm-gear tooth, high-abrasive material are composited.
Described base steel abrasion-proof duplex metal worm gear is to form with alloy silk blast fusion technology bonding.
Accompanying drawing 1 is a base steel abrasion-proof duplex metal worm gear arrangement schematic representation of the present utility model, is a most preferred embodiment of the present utility model.
Among Fig. 1,1 bronze medal or aluminium alloy layer, 2 worm-gear tooths, 3 worm wheel bodies are described in further detail base steel abrasion-proof duplex metal worm gear of the present utility model below in conjunction with accompanying drawing.
Inventive concept of the present utility model, system is with the high strength of Fine Steel Casting iron and good temperature and pressure performance and copper (aluminium base) alloy good wear performance, combine by special process, constitute the new type worm wheel of double metallic composite material, so both guaranteed function of use, again simplified design technology, (, generally do not carry out the tooth root bending fatigue strength and check Gu worm-gear tooth makes base steel into.) machine volume is reduced, reduce cost greatly, save a large amount of valuable copper materials.
Course of working of the present utility model, be earlier with carbon constructional quality steel (low alloy steel) machine shaping, adopt copper (aluminium base) alloy silk blast fusion technology again, make between copper (aluminium base) alloy and the base steel molecule and combine, form the new antifriction alloy layer that one deck matter is close, the surface is very smooth, combination force is extremely strong, alloy layer thickness can be made by oneself according to usage requirement.
Base steel abrasion-proof duplex metal worm gear of the present utility model compared with prior art has following advantage:
1, simplified design technology (generally not carrying out the tooth root bending fatigue strength checks).
2, volume is little, intensity is high, the temperature and pressure performance is good.
3, adopt cold processing technique, quality of product is easy to guarantee, technology is simple.
4, cost low, save a large amount of noble metals.
5, product has good wear performance and wear-resisting property, improves worm gear working life, reduces rate of fault.
