Abstract
The invention discloses a tin-based bearing composite material. The bearing composite material comprises, by weight, 15-25 parts of magnesium borate whisker, 5-15 parts of nano-Mo particles, 5-15 parts of a filling material, 40-50 parts of polylactic acid, 20-30 parts of polyhedral oligomeric silsesquioxane, 10-20 parts of tin element and 1-5 parts of a coupling agent. Through the above mode, the composite material of the invention has high strength, can bear large pressure and has good wear resistance.
Description
Technical field
The present invention relates to field of compound material, particularly relate to a kind of tin-base bearing matrix material.
Background technology
The material mainly non-ferrous metal of sliding surface bearing.Conventional has tinhase bearing metals, graphite metal, copper base bearing metals, Z-alloy etc.
Tinhase bearing metals (tin-base babbit).It is matrix element with tin, adds the alloy that antimony, copper etc. are elementary composition.This alloy friction is little, plasticity and thermal conductivity good, be excellent antifriction material, be commonly used for important bearing, as the high-speed bearing of the megamachines such as steam turbine, engine, pneumatic plant.Its main drawback is that fatigue strength is lower, and tin is more rare, therefore this bearing metal price is the most expensive.
Graphite metal (lead-base babbitt).The alloy of its to be lead-antimony be base.Add tin and can form SnSb Hard Inclusion, and can be dissolved in lead in a large number and strengthen matrix, therefore intensity and the wear resistance of lead 2-base alloy can be improved.Add copper and can form CuSb Hard Inclusion, and prevent specific density segregation.Intensity, plasticity, toughness and the thermal conductivity of graphite metal, all comparatively tin-based alloy is low for solidity to corrosion, and frictional coefficient is larger; But price is more cheap.Therefore, during graphite metal is commonly used to manufacture and bears, the middling speed bearing of low load, as the bent axle of automobile, tractor, connecting rod bearing and motor bearing.
No matter be tinbase or graphite metal, their intensity all lower (σ b=60-90MPa), can not bear large pressure, therefore must by the bearing shell (be generally No. 08 steel drift molded) of its castingin at steel, form the thin and uniform liner of one deck, competence exertion effect.This technique is called " hanging lining ", just forms so-called bimetallic bearing after hanging lining.
