摘要

To increase the efficiency of the hydraulic axial piston pumps, we have to know the various characteristics in the sliding parts of them. Especially, friction characteristics between the valve plate and the cylinder block in the hydraulic axial piston pumps plays an important role to high power density. In this paper, we tried to clarify friction characteristics between the spherical valve plate and the cylinder block in bent-axis-type axial piston pump by using of modeling experiment. The main results of this study are these; (1) Friction torque between the spherical valve plate and the cylinder block has a proportional relation to weight or rotational speed, and is strongly affected by temperature. (2) Friction torque strongly depends on force balance ratio. (3) In this modeling experiment, lubrication condition between the spherical valve plate and the cylinder block is under hydrodynamic lubrication.
