Problems solved by technology

[0002] With the increasingly stringent requirements for the power, economy, environmental protection and reliability of the engine in the whole vehicle, the piston has developed into a multi-functional product integrating light-weight and high-strength new materials, special-shaped outer circle composite profiles, special-shaped pin holes, etc. A high-tech product integrating new technologies to ensure the heat resistance, wear resistance, stable guiding and good sealing function of the piston, reduce the friction work loss of the engine, reduce fuel consumption, noise and emissions, due to its It needs continuous reciprocating linear motion, so its outer surface is easy to wear, making its service life shorter

Embodiment Construction

[0011] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0012] Such as figure 1 As shown, a piston of an oil cylinder includes a hollow cylindrical piston body 1, one end surface of the piston body 1 is closed, and the other end surface of the piston body 1 is provided with a connection port connected to the piston rod 2. The outer peripheral surface of the piston body 1 is provided with a plurality of annular grooves 3 , and the centerlines of the grooves 3 coincide with the centerlines of the piston body 1 .

[0013] Such as figure 1 As shown, the cross section of the groove 3 is arc-shaped. The depth of the groove 3 is one third of the thickness of the piston rod body.

[0014] Such as figure 1 As shown,...

Abstract

The invention discloses a piston of an oil cylinder. The piston comprises a hollow and cylindrical piston body, one end face of the piston body is closed, a connecting opening connected with a piston rod is formed in the other end face of the piston body, a plurality of annular grooves are formed in the outer circumferential face of the piston body, and the central lines of the grooves coincide with the central line of the piston body. When the piston and a cylinder sleeve rub in the movement process, oil films can be formed in the grooves of the piston so that the friction contact face can be reduced, the piston and the cylinder sleeve can be prevented from being in large-area contact, and therefore the function of resisting abrasion and preventing cylinder scuffing is achieved to the maximum extent.

Description

technical field [0001] The invention relates to a piston of an oil cylinder. Background technique [0002] With the increasingly stringent requirements for the power, economy, environmental protection and reliability of the engine in the whole vehicle, the piston has developed into a multi-functional product integrating light-weight and high-strength new materials, special-shaped outer circle composite profiles, special-shaped pin holes, etc. A high-tech product integrating new technologies to ensure the heat resistance, wear resistance, stable guiding and good sealing function of the piston, reduce the friction work loss of the engine, reduce fuel consumption, noise and emissions, due to its It needs to make reciprocating linear motion continuously, so its outer surface is easy to wear, making its service life shorter. Contents of the invention [0003] The object of the present invention is to overcome the defects existing in the prior art, and provide a piston of an oi...
