Beschreibung
Zusammenfassung:	The utility model discloses a connecting rod of a hydraulic motor, which is characterized in that an elliptical sealing ring is arranged on the end surface of a connecting part, the sealing ring is integrally connected with the connecting part, an elliptical sealing oil cavity is enclosed by the sealing ring and the end surface of the connecting part, and a coating for reducing the friction coefficient is arranged on the surface of the sealing ring. The four corners of the end face of the connecting part are each provided with a supporting face protruding upwards, and the supporting faces are located on the outer side of the sealing ring. The motor has the advantages that the sealing ring is prevented from falling off and is convenient to process, and the coating on the surface of the sealing ring reduces the friction coefficient, prolongs the service life of parts, improves the mechanical efficiency of the motor and reduces the heat productivity; the pressure generated by high-pressure oil in a motor cylinde
