Abstract
The utility model relates to a bearing bush of a medium-speed high bearing compressor. The bearing bush comprises a bearing bush body, an oil hole, an oil groove and a positioning key, wherein the oil groove is formed in the middle of an inner circle surface of the bearing bush body along a cambered surface; the oil hole is formed in any position of the oil groove; the positioning key is arranged at one end of the bearing bush body; thrusting sides are arranged on the upper edge and the lower edge of the outer circle surface of the bearing bush body uniformly and horizontally; and a steel plate alloy composite material layer and a functional clad layer are arranged on the inner ring surface of the bearing bush body from the interior to the exterior sequentially. The bearing bush is simple in structure, high in high temperature resistance and good in lubricating property, and the serve life of the bearing bush is prolonged.
Description
Technical field
The utility model relates to the mechanical fitting field, particularly relates to a kind of middling speed high-mechanic bearing liner for compressor.
Background technique
Bearing shell is the main accessory of the internal-combustion engines such as diesel engine, petrol engine and engineering machinery class, the accessory that also is used for simultaneously the Engineering movable machineries such as compressor, water injection pump, it also is main quick-wear part, development along with Hyundai Motor, communications and transportation, farm machinery and engineering machinery, the demand of its engineering machinery is in rising trend, and is more and more extensive to the application technology of bearing shell.
Bearing shell is sliding bearing, and working surface is that abrasion resistance alloy (copper base alloy, acieral) liner is the bimetallic material of low carbon steel.Bearing shell on the engineering machinery is divided into connecting rod bearing shell and crank spindle watt (main axle bush and thrust bearing shell), wherein must have on every machine of thrust main axle bush a pair of, the external end thrust that its effect also will make crankshaft operation keep axially locating and bear bent axle except the effect of bearing main axle bush.
Middling speed high-mechanic compressor is significant components commonly used in the machinery, work under bad environment, be installed in resistance to high temperature and wear-resisting property that bearing shell in the High-pressure Reciprocating water injection pump will be very strong, present supporting bearing shell often working life low, the performance of middling speed high-mechanic compressor is had a great impact.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of middling speed high-mechanic bearing liner for compressor, and is simple in structure, and resistance to high temperature is high, and greasy property is good, has improved working life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of middling speed high-mechanic bearing liner for compressor is provided, comprise bearing shell body, oilhole, oil groove and positioning key, have between two parties an oil groove along cambered surface on the inner headed face of described bearing shell body, arbitrary position on the described oil groove has oilhole, one end of described bearing shell body is furnished with positioning key, the equal lateral arrangement in the upper edge of the periphery of described bearing shell body and lower edge has the thrust side, and the inboard disc of described bearing shell body is furnished with steel plate alloy composite materials layer and functional coating from inside to outside successively.
Described functional coating is comprised of nickel dam and tin copper coating, and described nickel dam is connected with steel plate alloy composite materials layer.
Several thrust side oil grooves have been evenly arranged on the outer surface of described thrust side.
Beneficial effect
The utility model relates to a kind of middling speed high-mechanic bearing liner for compressor, and is simple in structure, has the following advantages: it is lubricated that (1) adopts the design of oilhole oil groove to be added to radial motion, so reduced frictional force between movement parts, the product wearing and tearing reduced improve product working life.(2) adopt nickel and tin copper coating, nickel dam acts under composite material and the functional coating chien shih active force coating can be because of the first composite inner diffusion of excess Temperature, improve the stability of functional coating, and produced the problem that high-bearing capacity reduces product working life when adopting the tin copper coating to solve the middling speed operation during boundary friction, simultaneously because tin is the lubricity that product has been improved in the soft metal.
