LAGGING ANGLE BETWEEN THE DRIVING FLANGE AND THE CYLINDER BLOCK IN CASE OF AXIAL PISTON PUMP WITH ROTARY MOTION TRANSMITTING BY CONNECTING RODS

Abstract

In this paper the variation of the lagging angle between the cylinder block and driving shaft in case of axial piston pumps with transmitting of the rotary motion by connecting rods (APPTRMCR) is studied, accordingly to the peculiarity of these types of hydraulic machines, and namely, the transmitting of the rotary motion from the driving flange to the cylinder block by means of connecting rods. It is studied the case of a mechanism having a single ensemble connecting rod-piston, therefore, in the case where the connecting rod is always in contact with the inside wall of the piston cup. The performed analysis is exemplified for the pumps F132 and F232 realized by S.C. Plopeni S.A. The paper results are useful to study the accurate kinematics of APPTRMCR, by establishing the variation laws of the lagging angle in case of occurring a z connecting rods/pistons, from which a single connecting rod is in the state of driving connecting rod, at a given moment.
