Abstract

PURPOSE:To quantitatively grasp loads applied on gears by setting the rotational speed (torque) of the output shaft of a rotary ram cylinder device at an arbitrary value in the surface of the rotational angle of the rotary ram cylinder device and the cylinder stroke of the load cylinder. CONSTITUTION:The output shaft of a rotary ram cylinder device 23 is connected to the lateral input shaft 30 of an S-case assembly 5 through an electromagnetic clutch 18, and a load cylinder actuated by the sprocket of a final device connected to the S-case assembly 5 side, is provided at the stationary side. Further, a relief valve for adjusting the exhaustion pressure of a pump is provided in an operating oil pressure circuit of the rotary ram cylinder device 23, and a circuit for communicating the load head side to the operating oil pressure circuit of the load cylinder with the tank through a solenoid valve and a flow rate adjusting valve, is provided at the operating oil pressure circuit of the load cylinder.
