Abstract
The invention discloses a duplex metal cylinder body applicable to a hydraulic pump or a motor. The duplex metal cylinder body comprises a steel substrate, wherein a copper alloy layer is arranged on a plunger hole and an oil distribution disk surface of the steel substrate in a melting and casting mode; the copper alloy layer is composed of copper, tin, lead, nickel and zinc, wherein the lead content is controlled to be 10.5%. The duplex metal cylinder body enables a friction pair of the cylinder body to have the optimal lubricating property when the hydraulic pump or the motor works.
Description
Technical field
The present invention relates to a kind of bimetallic cylinder, particularly a kind of bimetallic cylinder that applies to oil hydraulic pump or motor.
Background technique
Cylinder body is the vital part of hydraulic pump/motor.In hydraulic pump/motor working procedure, cylinder body end face and oil distribution casing fit tightly, and plunger high speed to-and-fro motion in cylinder body plunger hole, completes suction/oil extraction work jointly simultaneously.In this process, the matching problem of above two friction pairs is most important.
The material that the cylinder body of most domestic hydraulic pump/motor adopts is at present single magnesium iron or bimetallic cylinder.Long-term test discovery, if solved the greasy property problem of friction pair, the performance of so whole friction pair will get a new look.But still relevant producer or R&D institution are studied causing the material of change friction lubricating performance at present.
Summary of the invention
The object of the invention is to, a kind of bimetallic cylinder that applies to oil hydraulic pump or motor is provided.The invention enables hydraulic pump/motor when work, the friction pair of cylinder body can have best greasy property.
Technological scheme of the present invention: a kind of bimetallic cylinder that applies to oil hydraulic pump or motor, is characterized in that: comprise steel base, founding copper alloy layer on the plunger hole of steel base and oil distribution casing face; Copper alloy layer is comprised of copper, tin, lead, nickel and zinc, and wherein lead content is controlled at 10.5%.
In aforesaid bimetallic cylinder, described tin content is controlled at 9%-11%.
In aforesaid bimetallic cylinder, described tin content is controlled at 10%.
In aforesaid bimetallic cylinder, described nickel content is controlled at 2%-4%.
