Abstract
This study focuses on addressing the issue of significant leakage under 32 MPa high pressure during clockwise rotation in a certain type of internal cam radial piston motor.By conducting finite element analysis simulations on the port plate,and based on the theory of radial laminar flow between parallel plates,it was determined that the substantial deformation(0.015 mm)of the port face of port plate at 32 MPa under clockwise rotation is the primary cause of the high leakage(3.5 L/min)on this side.By optimizing the port plate structure and upgrading the material grade,the deformation of the port face under clockwise 32 MPa high-pressure conditions is reduced to 0.0084 mm.Experimental validation revealed that the leakage of motor with optimized port plate reduced to 0.55 L/min at 32 MPa pressure under clockwise rotation,representing an 84%decrease compared to the original design.The results provide simulatio and theoretical guidance for optimizing the leakage in similar types of piston pumps and motors.关键词
