The cost of the zinc base alloy materials adopted to manufacture the marine machinery turbine is 40 percent lower than that of the tin bronze materials and 60 percent lower than that of babbitt metal, and the service life of the zinc base alloy materials is 1.5-4 times higher than the service life of the tin bronze materials and the babbitt metal.
Description
Technical field
The invention belongs to marine deck machinery manufacturing technology field, relate to a kind of method that adopts Zn-base alloy to make the marine machinery turbine.
Background technology
As everyone knows, the marine deck machinery manufacturing industry all is to adopt the rapidoprint of tin bronze material as turbine all the time, because of its better machining property is being brought into play leading effect for a long time in the deck machinery field of making.Yet continuous progress along with industrial technology; The continuous lifting of productivity; Be the demand that the turbine of material can not fully satisfy current people with the tin bronze, and zinc-containing alloy has remedied with all advantages just and uses tin bronze as the existing weak point of turbine material in the past.Zn-base alloy is compared with tin bronze, and its major advantage is following:
1, mechanical performance is more superior.The tensile strength of Zn-base alloy is higher, and its tensile strength is 420Mpa under the metallicity as cast condition, and the homogenising treatment state is 350Mpa down, and tin bronze tensile strength is 220Mpa; Brinell hardness is higher, and the Brinell hardness under the metallicity as cast condition of Zn-base alloy is 110HBW, and the uniform treatment state is 90HBW, and the Brinell hardness of tin bronze is 80HBW;
2, friction and wear characteristic is better.Under equal conditions, the PV of zinc-containing alloy (pressure-speed) characteristic is superior to tin bronze, and its coefficient of friction is also lower than tin bronze, and the coefficient of friction of zinc-containing alloy is 0.03～0.07, and the coefficient of friction of tin bronze is about 0.1;
3, price is cheaper.Zn-base alloy existing market price is about 3.5 ten thousand yuan/ton, and tin bronze existing market price is about 9.5 ten thousand yuan/ton, and the Zn-base alloy cost is about the 35-40% of tin bronze material;
4, weight is lighter.The density of Zn-base alloy is 5g/cm
3, and the density of tin bronze material is 7～9g/cm
3, Zn-base alloy weight is lighter, is about the 55-70% of tin bronze material.
Can know that by above contrast Zn-base alloy has enough advantages to substitute the making that the tin bronze material is applied to mechanical turbine.
Summary of the invention
The objective of the invention is to use the existing problem and shortage part of tin bronze material, and adopt the method for the Zn-base alloy making marine machinery turbine that a kind of performance is more superior, price is cheaper to traditional deck machinery drive disk assembly.
Method and step that technical solution of the present invention realizes are:
The first step: roughing.Be about to the Zn-base alloy blank and carry out roughing, comprise turning, car endoporus and end face processing, process the zinc-containing alloy annulus;
Second step: fine finishining.The zinc-containing alloy annulus that roughing is processed carries out fine finishining, comprises smart boring, endoporus, car circular arc, then with zinc-containing alloy annulus and wheel hub assembling, with the alignment pin location, processes zinc-containing alloy circle wheel;
The 3rd step: the rolling gear teeth.Zinc-containing alloy circle wheel is processed in fine finishining be placed on the rolling gear teeth on the rolling gear teeth machine, process the zinc-containing alloy turbine.
A kind of Zn-base alloy described in the technical solution of the present invention is made the method for marine machinery turbine, and the main component of its Zn-base alloy is: Al, 25.0-28.0%; Cu, 2.0-2.5%; Mg, 0.01-0.020%; Fe, 0.075%; Pb, 0.006%; Cd, 0.006%; Sn, 0.003%; Surplus is Zn.
The invention has the beneficial effects as follows: solved conventional turbine (the crucial drive disk assembly on the deck machinery) because of using tin bronze material PV (pressure-speed) characteristic relatively poor, coefficient of friction is bigger, thereby anti-wear performance causes the relatively poor drawback of complete machine service behaviour inadequately.In addition, because the zinc-containing alloy market price is cheaper, solved the problem of Harmann Berstorff, Maschinenbau GmbH's entreprise cost waste.Through actual specific, it is lower by 40% than tin bronze to adopt Zn-base alloy to make its cost of marine machinery turbine, lower by 60% than babbit, 1.5 to 4 times of high life.
The Zn-base alloy turbine that adopts technical scheme of the present invention to make, shown in the following table of related data of its mechanical performance, anti-wear performance, processing characteristics, physics and chemistry test and traditional tin bronze material contrast:
