Abstract
The utility model provides a laser-carving connecting rod bearing which comprises a tile-shaped steel backing, wherein, the inner side of the steel backing is equipped with a bearing alloy layer; the inner side of the bearing alloy layer is equipped with honeycombed lubricating oil wire grooves which are not communicated with each other; the bearing alloy layer is connected with the steel backing by the modes of casting, sintering or rolling; the lubricating oil wire grooves are in a rectangular shape, a circular shape and a rhombic shape; and the bearing alloy layer is made of an aluminum-base alloy or an copper-base alloy. The laser-carving connecting rod bearing has the advantages of improved bearing capacity and prolonged service life.
Description
Technical field
The utility model relates to a kind of laser and carves and chisel connecting rod bearing shell.
Background technique
Along with motor at a high speed, carry by force, direction such as energy-conservation, efficient develops, to will improving constantly of connecting rod bearing shell.Require bearing shell to have big bearing capacity and fatigue strength, will have good seizure resistance, allowing property of embedding, compliance, anti-corrosion property, compressive strength and antifriction quality simultaneously.General engine link watt is made up of steel backing, base layer, nickel-barrier layer, antifriction layer, the production technology more complicated, and the cost of production height, greasy property is not so good.
The model utility content
The utility model purpose is to provide a kind of laser to carve to chisel connecting rod bearing shell, long service life, save cost, bearing capacity is big.
To achieve these goals, the utility model adopts following technological scheme: a kind of laser is carved and is chiseled connecting rod bearing shell, comprises the steel backing of watt shape, and the inboard of steel backing is provided with bearing alloy layer, and the bearing alloy layer inner side surface is provided with the lubricant oil wire casing.
Described bearing alloy layer inner side surface is provided with cellular lubricant oil wire casing, and each lubricant oil wire casing does not connect mutually.
Between described bearing alloy layer and the steel backing be connected to that casting is connected, sintering connection or rolling connection.
Described lubricant oil wire casing is rectangle, circle, rhombus.
Described bearing alloy layer is acieral or copper base alloy.
Bearing alloy layer of the present utility model is arranged on the steel backing, on bearing alloy layer, adopt laser to carve to chisel machine engraving to chisel uniform lubricant oil wire casing is arranged, and each lubricated wire casing does not connect mutually, make bent axle when moving the commentaries on classics, the friction of chiseling connecting rod bearing shell with laser quarter forms liquid friction (fluid friction) thereby the raising antifriction quality, improve laser and carved bearing capacity, the working life of chiseling connecting rod bearing shell, saved cost, bearing capacity is big.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a plan view of the present utility model.
Embodiment
Embodiment: as shown in Figure 1 and Figure 2, a kind of laser is carved and is chiseled connecting rod bearing shell, the steel backing 1 that comprises watt shape, the inboard of steel backing 1 is provided with bearing alloy layer 2, adopt laser to carve on bearing alloy layer 2 inner side surfaces to chisel machine engraving to chisel cellular lubricant oil wire casing 3 is arranged, lubricant oil wire casing 3 is a linear structure, each lubricant oil wire casing 3 does not connect mutually, make bent axle when moving the commentaries on classics, the friction of chiseling connecting rod bearing shell with laser quarter forms liquid friction (fluid friction) thereby the raising antifriction quality, has improved laser and has carved bearing capacity, the working life of chiseling connecting rod bearing shell.Certainly, lubricant oil wire casing 3 also can be the structure that connects, but is not optimum embodiment.
Bearing alloy layer 2 is acieral or copper base alloy, between bearing alloy layer 2 and the steel backing 1 be connected to that casting is connected, sintering connection or rolling connection.Lubricant oil wire casing 3 is shapes such as rectangle, circle, rhombus.
Claims (5)
