Abstract
The invention discloses a copper base alloy material for a sliding bearing, comprising copper-tin-nickel alloy consisting of 7 to 9 wt % of tin, 0.7 to 1.3 wt % of nickel and the balance of copper. The material has advantages of environment protection, no lead, high bearing capacity, corrosion resistance, high temperature resistance, stability and non-deformation, and overcomes the disadvantages of high lead content and no environmental protection in similar materials of the prior art.
Description
Technical field
The present invention relates to material for sliding bearing, be specifically related to a kind of novel copper-based alloy material for sliding bearing that oil engine is used.
Background technology
Sliding bearing of the internal-combustion engine mainly comprises bearing shell, lining, flange watt and thrust plate.The main effect of sliding surface bearing has: 1, bolster and parts on shaft, the running accuracy of retainer shaft; 2, the friction and wear between minimizing rotating shaft and the supporting.For the occasion that needs subdivision on high speed, heavy duty, high precision, the structure, need to adopt sliding surface bearing, as steam turbine, radial compressor, oil engine, large-size machine etc.Therefore sliding surface bearing is the strength member in the sliding bearing of the internal-combustion engine, and as one of part of engine most critical, the quality of material for sliding bearing performance directly affects the performance of engine.Along with oil engine to height carry, the environmental protection direction develops, the bearing shell performance demands is improved constantly, require material for sliding bearing that high supporting capacity and fatigue resistance are not only arranged, have the favorable environment protection energy simultaneously, also do not have a kind of material for sliding bearing that can satisfy above-mentioned requirements at present.In addition, traditional copper-based alloy material is a kind of copper-lead bimetal steel band (as CuPb20Sn4, CuPb24Sn etc.), and it has obtained using widely on the high-mechanic oil engine.Problem is to contain lead in this material, and plumbous content is bigger to environmental disruption than higher, does not meet the social development needs, and society presses for the environment-friendly type copper-based alloy material for sliding bearing that a kind of energy substitutes the traditional copper base alloy material at present.
Summary of the invention
Task of the present invention be to overcome the existing contaminate environment of prior art material, supporting capacity is low and the defective of fatigue resistance difference, and a kind of environmental protection is provided, high bearing capacity, and the good novel copper-based alloy material for sliding bearing of fatigue resistance.
Technical scheme of the present invention is:
A kind of copper-based alloy material for sliding bearing is characterized in that: described copper-based alloy material for sliding bearing is made of the copper tin-nickel alloy, and the weight percentage of each element is in the copper tin-nickel alloy: tin 7～9%, and nickel 0.7～1.3%, surplus is a copper.
Described copper tin-nickel alloy is a sintered powder.
Preferred scheme is:
The weight percentage of each element is in the described copper tin-nickel alloy: tin 7%, nickel 1.3%, surplus copper.
Perhaps: the weight percentage of each element is in the described copper tin-nickel alloy: tin 9%, and nickel 0.7%, surplus is a copper.
Perhaps: the weight percentage of each element is in the described copper tin-nickel alloy: tin 8%, and nickel 1%, surplus is a copper.
Perhaps: the weight percentage of each element is in the described copper tin-nickel alloy: tin 7.5%, and nickel 1.2%, surplus is a copper.
Perhaps: the weight percentage of each element is in the described copper tin-nickel alloy: tin 8.5%, and nickel 0.8%, surplus is a copper.
The present invention has following beneficial effect:
Content plumbous in the existing glide bearing copper-based alloy material is up to more than 20%, and environmental pollution is serious.What compared with prior art, copper-based alloy material for sliding bearing of the present invention adopted is a kind of copper tin-nickel alloy.Because not leaded, the present invention has prevented that fully material is in use to the pollution of environment.In the material of the present invention, tin has excellent corrosion resisting performance, and nickel can improve the modulus of elasticity of alloy, plays the effect of reinforced alloys.Copper base alloy (the being stratum basale) material that material of the present invention can be used as sliding surface bearing uses, and has the advantage of high-bearing capacity, corrosion-resistant, high temperature resistant, indeformable good stability and environmental protection with the bearing shell of material manufacturing of the present invention.Because the copper tin-nickel alloy is a sintered powder, be to adopt the powder sintering process manufacturing, thereby do not need existing equipment is improved on a large scale, can reduce manufacturing cost greatly, easily promote.
