Abstract
In the present work a theoretical method has been proposed to predict the starting torque characteristics of constant difference epitrochoid generated orbital rotary piston hydraulic motors.For the analysis of such class of Low Speed High Torque(LSHT)hydraulic motors, design and manufacturing data of a few variety of products have been used in the computer calculations to estimate the variation of torque with shaft position over a power cycle.Effects of various factors such as fitting of the rotor-stator (i.e., star-ring), drives, interchamber leakage and their variations with shaft positions have been considered.Finally experiments have been conducted to establish the theoretical model.Experimental result have good agreement with theoretical predictions.
