FUNCTIONAL GEOMETRY OF THE PUMPS WITH AXIAL PISTONS AND WITH ROTATING MOTION TRANSMITTING BY CONNECTING RODS

Abstract

In this paper, for the first time in a complete form, the functional geometry of the mechanism in case of pumps with axial pistons, with rotating motion transmitting by connecting rods is presented, taking into account the peculiarity of these types of hydraulic machines, and namely the rotary movement transmitting from the driving flange to the cylinder block, by means of a connecting rod called driving connecting rod. On the basis of some geometrical and working, structuralkinematical, respectively, arguments and of some calculations, the geometrical (linear and angular) sizes which characterize from functional (kinematical) point of view the analyzed mechanism are determined. These geometrical-functional considerations and determinations are useful for the study of the distribution process and realization of the distribution slots and for studying the accurate kinematics and dynamics of these hydraulic machines.
