説明

<p>In order to understand motion mechanisms of slippers in swash plate type piston pumps, the analysis flow combining multi-body dynamics and the oil-film analysis was constructed. This analysis evaluated the effects of elastic deformation of the retainer on the slipper behavior. The retainer is deformed by the spring force so that the outer circumference of the retainer is tilted by about 20 µm. Due to this deformation, the analysis result was obtained in which the center displacement of the slipper was reduced and the tilt angle was increased. Deformation of the retainer has a great effect on the behavior of slippers.</p>
