Abstract
The utility model discloses a double-metal bearing painted with a lubricating layer which aims to provide a double-metal bearing painted with a lubricating layer with simple structure and large load yet without the phenomenon of 'mating shaft' or the early abrasion in the early phase of usage. The utility model comprises a split shaft collar or a plate made from a composite consisting of at least two cascade materials including steel and copper, and is characterized in that a lubricating film is coated on the surface of the copper alloy. The lubricating film coated on the surface of the copper alloy of the utility model accomplishes the lubricating function in the early phase of the mechanical harmonization, thereby preventing the mating phenomenon or early abrasion in the early phase of the mechanical harmonization due to inadequate lubrication.
Description
Technical field
The utility model relates to the sliding bearing of composite material, relates in particular to a kind of bimetal sliding bearing of being made by steel and two kinds of stacked composite materials of material of copper at least, is coated with the bimetallic bearing of lubricating layer at its slidingsurface.
Background technique
At present, the sliding bearing that uses the more stacked composite material of steel-Cuprum alloy to make, their bearing capacities are big, wear resistance good, and user cost is low.But in use must have fully lubricatedly, and the oiling agent that often adds at use initial stage engaging friction surface fully is lubricated insufficient, causes premature wear or " stinging axle " phenomenon.
The model utility content
The purpose of this utility model be to provide a kind of simple in structure, bearing capacity big, the bimetallic bearing that is coated with lubricating layer of premature wear or " stinging axle " phenomenon can not take place at the use initial stage.
The technological scheme that is coated with the bimetallic bearing of lubricating layer in order to achieve the above object is: comprise split bush or the flat board made by steel and two kinds of stacked composite materials of material of Cuprum alloy at least, it is characterized in that being coated with one deck lubricating film on the copper alloy layer surface.
According to the bimetallic bearing that is coated with lubricating layer of such scheme manufacturing, behind copper alloy layer surface spraying one deck lubricating film, can the break-in initial stage by the lubricating film lubricate, avoid the break-in initial stage because of lubricating the phenomenon of insufficient generation interlock or premature wear.
