Example Embodiment

[0011] Refer to figure 1 , The present invention provides a hydraulic motor piston sealing ring, comprising: an O-ring 1 and a sealing ring 2. The inner side of the sealing ring 2 is provided with an arc-shaped groove 3 that matches with the O-ring 1. The sealing The outer side of the ring 2 is provided with an arc-shaped oil storage groove 4, and the sealing ring 2 forms arc-shaped protrusions 5 on both sides of the arc-shaped oil storage groove 4, and the arc-shaped protrusions 5 are in contact with the outer cylinder inner wall.

[0012] The piston sealing ring of the hydraulic motor of this embodiment is composed of an O-ring and a sealing ring. Lubricating oil can be placed in the arc-shaped oil storage tank, which can effectively reduce the working temperature and has a good noise reduction effect. It is in contact with the outer cylinder inner wall through the arc-shaped protrusion , Good sealing, stable overall structure, easy to realize.

[0013] The above are only the pr...

Abstract

The invention provides a piston sealing ring of a hydraulic motor. The piston sealing ring of the hydraulic motor comprises an O-shaped ring and a sealing ring, wherein an arc-shaped groove matched with the O-shaped ring is formed at the inner side of the sealing ring; an arc-shaped oil storage tank is arranged at the outer side of the sealing ring; and arc-shaped bulges are formed at the two sides of the arc-shaped oil storage tank of the sealing ring. The piston sealing ring of the hydraulic motor comprises the O-shaped ring and the sealing ring; lubricating oil can be placed in the arc-shaped oil storage tank; the working temperature is effectively reduced; the noise reduction effect is good; and the arc-shaped bulges are in contact with the inner wall of an outer cylinder, so that thepiston sealing ring of the hydraulic motor has a good sealing property and stable overall structure and is convenient to realize.

Description

technical field [0001] The invention relates to a hydraulic motor, in particular to a hydraulic motor piston sealing ring. Background technique [0002] The hydraulic motor is an actuator of the hydraulic system, which converts the hydraulic pressure energy provided by the hydraulic pump into the mechanical energy (torque and speed) of its output shaft. Hydraulic motors, also known as oil motors, are mainly used in injection molding machinery, ships, hoists, construction machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical, port machinery, etc. The overall sealing effect of some existing sealing rings installed on the pistons of hydraulic motors is not good, and cannot well satisfy some occasions such as high temperature resistance and fatigue resistance. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention i...
