Axial piston machine of swashplate type is the common design widely used for many hydraulic applications because of its simplicity, compact design and low cost. However, this simplicity has a negative effect for piston transverse forces which limits machine performance. The main target of this study is to investigate a feasible design of a fixed displacement swashplate contour in order to minimize piston transverse forces. The design should compensate the contact surface mechanism between swasplate and piston end. Piston slipper is replaced by a ball that is rotatably mounted within a ball socket formed at the piston end. The ball runs on a circumferential contour groove formed on the swashplate surface. The sliding friction between swashplate and slipper is replaced by a rolling friction between ball and circumferential runway groove. Primary results show a rough estimation of 30% reduction of piston transverse forces due to the cam action radial forces elimination. This reduction promises to enhance overall machine performance.
