Abstract
A test system for measuring a rotary load comprises a stepper motor drives a gear box that is mounted at one end of a frame. A torque sensor provides a measurement signal transmission. The gear box's output shaft is connected to one of the torque sensor's stubs by means of a universal joint coupling. On the other side of the torque sensor a second universal joint coupling connects the sensor to a stainless steel shaft. A low friction flange bearing is used to provide support for the shaft. An angle encoder is disposed on the end of the shaft distal to the gear box. The gear box's output shaft, the torque sensor's cylindrical shaft hubs and associated couplings are arranged such that they are directly aligned with the shaft. The test system has been designed to take automated torque and angle readings from a shaft capable of rotary motion. The measurement arm configuration with the stepper motor directly connects the torque and angle sensors to a PC based data acquisition card for acquisition and processing of data. The system operates according to a method used to make a true torque measurement of a rotary actuated shaft or wheel in a process where a first data set is acquired with…
