Abstract

The invention discloses a light-weight wear-resistant gear machinery part. The light-weight wear-resistant gear machinery comprises, by weight, 0.05-0.35% of carbon, 0.25-0.80% of copper, 0.002-0.03% of tin, 0.01-0.09% of cobalt, 0.4-2.5% of zirconium, 4.6-9.6% of boron, 0.0006-0.008% of ruthenium, and the balance of iron and adding elements. The light-weight wear-resistant gear machinery part is high in transmission efficiency, light in weight and wear-resistant, wear resistance is small and overlap ratio is high when gears start meshing and demeshing, and service livers of the gears are greatly prolonged.

Description

A kind of lightweight wear-resistant gear mechanical fitting
Technical field
The present invention relates to mechanical Component field, particularly relate to a kind of lightweight wear-resistant gear mechanical fitting.
Background technique
China Gear industry was developed rapidly in Tenth Five-Year Plan Period: the annual value of production of gear industry in 2005 is increased to 68,300,000,000 yuan by 24,000,000,000 yuan in 2000, and annual compound growth rate 23.27%, has become industry largest in Chinese mechanical basic part.With regard to the market demand and production scale, China Gear industry has surpassed Italy in global rank, occupies the 4th, the world.
The major defect of the current gear using is: transmission efficiency is not high enough, and weight ratio is heavier, and the gear teeth wear and tear larger when starting engagement and departing from engagement, caused contact ratio to reduce, and have shortened the working life of gear.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of lightweight, and transmission efficiency is high, and contact ratio is large, the lightweight wear-resistant gear mechanical fitting of long service life.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of lightweight wear-resistant gear mechanical fitting is provided, its constituent and percetage by weight content are as follows: carbon 0.05-0.35%, copper 0.25-0.80%, tin 0.002-0.03%, cobalt 0.01-0.09%, zirconium 0.4-2.5%, boron 4.6-9.6%, ruthenium 0.0006-0.008%, surplus is iron and adds element.
In a preferred embodiment of the present invention, its constituent and percetage by weight content are as follows: carbon 0.07-0.30%, copper 0.30-0.70%, tin 0.007-0.02%, cobalt 0.02-0.08%, zirconium 0.5-2.3%, boron 5.0-9.0%, ruthenium 0.0009-0.007%, surplus is iron and adds element.
In a preferred embodiment of the present invention, its constituent and percetage by weight content are as follows: carbon 0.18%, and copper 0.50%, tin 0.011%, cobalt 0.045%, zirconium 1.25%, boron 7.5%, ruthenium 0.003%, surplus is iron and adds element.
In a preferred embodiment of the present invention, described interpolation element comprises nitrogen, phosphorus and fluorine.
In a preferred embodiment of the present invention, the content of described interpolation element is less than or equal to 0.05%.
The invention has the beneficial effects as follows: transmission efficiency of the present invention is high, lightweight, wear-resistant, the gear teeth wear and tear smaller when starting engagement and departing from engagement, and contact ratio is large, has greatly extended the working life of gear.
