Abstract
A kind of sintered iron base oil containing bearing material be fit to be made supporting capacity and the behaviour in service sliding surface bearing that all has certain requirements, as the diesel engine connecting bar lining etc.The main component of this material is an iron, and sintering temperature is lower, and its performance and tinbronze are suitable.Make bush of bush bearing with it, can save non-ferrous metal, save energy reduces product cost.
Description
The present invention relates to a kind of material for sliding bearing that obtains with powder metallurgical technique.It is fit to be made supporting capacity and the behaviour in service sliding surface bearing that all has certain requirements, as the diesel engine connecting bar lining etc.
Existing sintered iron base bearing materials supporting capacity and behaviour in service " killing " phenomenon often takes place, and sintering temperature are between 1050～1150 ℃ not as tinbronze.Introduced F in " powder and powder metallurgy " that Japan publishes in November, 1980
e-10Pb-5C
uMaterial (master) has been introduced the F that is used for motor bearing of washing machine in third and fourth phase in 1985 " powder metallurgy technology " that China publishes
e-C
u-Pb-S material and the F that is used for micromachine bearing on the conditioner
e-C-C
u-S material yet there are no a kind of report that replaces the sintered iron base oil containing bearing material of tinbronze, as is used to make the sintered iron base oil containing bearing material of diesel engine connecting bar lining.
Task of the present invention is to improve existing sintered iron base oil-containing sliding bearing material property, to replace the application of expensive tinbronze on bearing.
Task of the present invention is finished as follows: the composition and proportioning and its sintering temperature that change sintered iron base oil containing bearing material.Material composition of the present invention and proportioning thereof are F
e-10Pb-0.5～1.0S
n-1.0～2.0C
u, sintering temperature is 800～900 ℃ after the compression molding.
Material supporting capacity of the present invention and behaviour in service are suitable with tinbronze.Make the material for sliding bearing lining with it, can save non-ferrous metal, the energy, reduce product cost.
Below the present invention is further described.
Get 1.75 unit weights-200 order electrolytic copper powder, 0.75 unit weight-320 order atomization tin powder, 10 unit weights-300 order atomized lead and add in the 87.5 unit weights-100 order reduced iron powder, drop into compression moulding in the product mold behind the uniform mixing, make density be equal to or greater than 6.8 gram per centimeters
3, put it into then in the reducing atmosphere sintering electric furnace, under 800～900 ℃ of conditions, carry out sintering, can get the material of the present invention of 100 unit weights after about 1.5 hours.
