• 要約等: Static characteristics of closed circuit hydrostatic transmission in bench test set-up were scrutinized quantitatively.<br>Unlike fixed-displacement axial-plunger motor, pump used varies continuously its displacement from zero to 30cc/rev.<br>Analyses reveal following findings;<br>1) Resonant phenomena within fluid lines might appear at 1000rpm in input shaft, and almost identical with output shaft due to inherent periodic variations of flow rate and torque.<br>2) Maximum overall transmission efficiency can be obtained at allowable maximum line pressure under constant speed ratio.<br>Torque ratio draws nearly linear relationship with speed ratio.<br>3) P/μn and T/nμD, both are dimensionless terms, show disobedience to wilson's expression. It is of greatly interest to recognize that kinematic viscosity of hydraulic oil plays significant roles for the transmission efficiency.<br>4) Leakage of pump increases linearly up to 1800rpm in input shaft, after that increases more rapidly. It indicates the failure of application of the theory of laminar flow.
