Abstract
The invention discloses a kind of tin alloy lines, and the molybdenum element of 0.3~10% weight fraction is introduced on the basis of tin-base babbit base material.Molybdenum element is introduced in the form of the molybdenum powder of plating nickel on surface, and molybdenum powder median is 0.5~2.5 micron, is finally still present in wire rod with the state of molybdenum particle；It is machined to line footpath φ 2.0mm by technical finesse hereinafter, tin antimony hard phase is refined, elongation after fracture can reach 10% or more.Experiments have shown that the present invention is welded into the jewel of oil film bearing shell for MIG and TIG heaps, overlay cladding is significantly improved with the steel back bottom more conventional centrifugal casting technique of bond strength；The introducing of molybdenum particle improves its anti-dry friction performance, and the bonding for reducing bearing neck and babbit metal bearing lining when Sliding bush is shut down is inclined to, and reduces adhesive wear when babbit metal bearing lining starts.Therefore compared with conventional centrifugal babbitting bearing shell, the bearing shell service life made of a kind of tin alloy line built-up welding of the present invention significantly improves.
Description
Technical field：
The present invention relates to a kind of tin alloy lines, specifically a kind of for making sliding filmatic bearing bearing lining material
Tin-base babbit wire rod, belongs to technical field of nonferrous metal processing.
Background technology：
Sliding bearing is one of the important support component in machine driving, and because of its large carrying capacity, reliability is high, structure is tight
The advantages that gathering and be used widely.Antifriction material (bearing lining material) layer in the bearing shell of sliding bearing is currently mainly used bar
Family name's alloy, is realized and the combination of steel back bottom (backing) by way of centrifugal casting, although there is many advantages；But there is also bearings
Material layer combined bad, ingredient to be easily segregated with matrix, is also easy to produce crackle, loose and slag inclusion, not environmentally the defects of.In addition, bearing
Material layer cast thickness larger (10~15mm) and it is processed after finished product layer thickness there was only 1.5mm or so, therefore once lumber-preserving
Rate is low, and waste of material is big.In order to which the centrifugal casting technique for solving the problems, such as traditional exists, large-scale filmatic bearing main at present becomes
Babbit metal bearing lining is made in the mode using arc surfacing, such as TIG welderings or MIG welderings.Since electric arc has steel back itself
Cleaning the effect of activation, the babbit layer of built-up welding and the bond strength of back end improve 30 than traditional centrifugal casting technique~
50%, significantly improve the reliability of sliding bearing military service process.In addition, for traditional centrifugal casting technique, electricity
Arc technique for overlaying eliminates the casting flaws such as shrinkage cavity is loose, reduces the babbit layer thickness of bearing shell blank, improves material
Utilization rate, therefore arc surfacing has been increasingly becoming the mainstream technology in the sector.
Although arc surfacing technology has many advantages in manufacture sliding oil film bearing shell, during studying its failure analysis
It was found that during some heavily loaded machine downs, it is very big that axle journal and bearing shell surface contact static pressure, between fail to form oil film and send out
Life is in direct contact, and the non-ferrous metals atom such as tin, antimony, copper is easy by diffusing into journal surface, so occur journal surface with
Bearing shell it is viscous, when being again started up machine, axle journal rotation will take away the material on part bearing shell surface, and apparent adhesion mill occurs
Damage, causes bearing shell to damage, especially certain devices for needing frequent starting, such as high-power wind turbine main shaft, and the service life can be caused anxious
It falls sharply low.
On the other hand, traditional relatively low, creep resistant using antimony copper as the tin-base babbit matrix strength of main alloy element
Performance is poor, and after heavy duty and frequent starting operating mode lower bearing long service, hair is locally easy with the bearing shell of axle journal relative position
Change shape, reduces dynamic pressure oil film thickness, and deformation boss is even in direct contact generation dry friction with axle journal, leads to bearing shell
Damage, reduces bearing life.
With the development of sliding bearing application field, industry has wished to that a kind of wear-resisting property is good, anti-creep-resistant property is excellent
Good babbit new material occurs, to meet sliding bearing application field to babbit wire rod performance requirement.
Invention content：
The purpose of the present invention is overcoming above-mentioned the deficiencies in the prior art, provide a kind of kamash alloy line containing molybdenum, have compared with
High plasticity, it is ensured that built-up welding unwrapping wire process does not break, and the anti-axle journal occlusion performance and creep resistance of jewel overlay cladding can be improved,
It is finally reached the purpose for improving bearing shell service life.
The present invention solve the technical problem scheme be：
A kind of tin alloy line, matrix alloy component are respectively by weight percentage：Antimony 7~12%, copper 3.5~
6.5%, nickel 0~0.8%, aluminium 0~0.09%, tellurium 0~0.2%, zinc 0~2%, silver 0%~0.6%, molybdenum 0.3~10%, always
Impurity of the amount no more than 0.05%, surplus is tin.
A kind of tin alloy line：The content of nickel is preferably 0.6%, and the content of aluminium is preferably 0.08%, the content of tellurium
Preferably 0.1%, the content of zinc is preferably 1.6%, and silver-colored preferred content is 0.5%.
A kind of tin alloy line, including molybdenum element, studies have shown that adding molybdenum element, Ke Yiming in alloy of the present invention
Aobvious to improve creep-resistant property and reduce static pressure adhesive wear, the preferred content of molybdenum element is 4.5~6.5%.
The molybdenum element of a kind of tin alloy line, the addition is molybdenum powder, and is finally still present in the form of molybdenum powder
In bearing shell, studies have shown that molybdenum powder grain size is excessive, there is the risk for scratching axle journal, grain size is too small, can reduce and delay adhesive wear
Effect, preferred median be 0.5~2 micron.
The molybdenum powder of a kind of tin alloy line, the addition is nickel plating molybdenum powder, the nickel plating of nickel plating molybdenum molybdenum powder particle surface
Layer thickness is 0.01~0.1 micron；Research shows that there are the transition zones of one layer of nickel on molybdenum surface, it is ensured that molybdenum powder particle is closed in Pasteur
Wetability in golden melt not only so that molybdenum powder forms metallurgical binding with matrix after solidification, but also makes molybdenum part be distributed in the alloy
Evenly.
One kind line of kamash alloy containing molybdenum, the nickel plating molybdenum powder of the addition, in being added to babbit melt it
Before, nickel plating molybdenum powder roasts 2~2.5 hours in 750 DEG C of reducing atmospheres or vacuum so that is sent out between nickel coating and molybdenum particle surface
Raw metallurgical binding further promotes bond strength of the molybdenum particle in alloy substrate.
Research shows that during bearing shell made of alloy of the present invention is on active service, it is uniformly distributed the tiny molybdenum with alloy substrate
Grain, since it is with higher hardness, plays the role of hard phase, and after axle journal and the initial running-in of bearing shell, molybdenum particle exists
Bearing shell surface bulge, and a small amount of nickel of protruding apex has been worn, remaining pure molybdenum is exposed in most surface.When shutdown rear shaft neck
When being in direct contact with bearing shell, exposed molybdenum particle can stick together to avoid axle journal and bearing shell, can obviously reduce when being again started up
Adhesion is worn, and the bearing shell service life is improved.
Research shows alloy of the present invention with good high-temerature creep drag simultaneously, while avoiding excessive zinc and silver is right
Babbit-lined metal performance has an adverse effect, and further improves the service life of bearing shell.
