Sealing structure for hydraulic motor

Abstract

The invention discloses a sealing structure for a hydraulic motor. The sealing structure comprises a sealing structure body, clamped between a sealed member I and a sealed member II, for the hydraulicmotor; at least two dowels are at least arranged on one side face of the sealing structure body for the hydraulic motor; the dowels are prisms; the diameters of circumcircles of the dowels are 2 to 4mm; the lengths of the dowels are 0.5 to 1.5 times those of the dowels; round dowel holes matched with the circumcircles of the dowels are correspondingly formed in the sealed member I or the sealedmember II on corresponding sides of the dowels; the distance between every two adjacent dowels is not longer than 200 mm; a guiding cone is arranged at the end part of each dowel. The sealing structure for the hydraulic motor can realize a sealing effect and has the characteristics of convenience and accuracy in mounting; in addition, the sealing structure is convenient to manufacture and low in cost.

Description

technical field [0001] The invention relates to a sealing structure for a hydraulic motor. Background technique [0002] The sealing structure for hydraulic motors is a sealing form with the simplest structure, the most convenient use and maintenance, and the lowest cost. Sealing structures for hydraulic motors are usually processed from relatively soft rubber, plastic or metal materials. The sealing structure for hydraulic motors is generally clamped between two mechanical parts or pipe flanges with sealing requirements through the action of bolts, etc., and fills the gap between two mechanical parts or pipe flanges with sealing requirements through its own deformation , so as to prevent the leakage or intrusion of various liquids, gases or solid particles. [0003] Since the material of the sealing structure for hydraulic motors is generally soft, the rigidity is often poor when the width of the sealing structure for hydraulic motors is narrow or the inner hole of the se...

AI Technical Summary

Problems solved by technology

However, processing grooves will increase the processing requirements of mechanical parts, and at the same time increase the thickness of the sealing structure for hydraulic motors, which will increase the cost of the sealing device; and the use of adhesives to paste the sealing structure for hydraulic motors will increase the use of The disassembly and replacement of the sealing structure is difficult, and the glue often interacts with the rubber or plastic hydraulic motor sealing structure to affect the material properties of the hydraulic motor sealing structure, thereby affecting the use effect and service life of the hydraulic motor sealing structure
