Development of a Computer Controlled Horizontal Type Reference Torque Machine

This paper introduces a horizontal type reference torque machine, which is composed of a movable workbench, a control system, a torque loading unit, intelligent standard sensors and a double rolling bearing support mechanism. Automatic or manual loading can be realized through the control system and loading unit. The DS2401 chips are used in standard sensors to avoid human error or wrong channel selection by finding the sensor coefficient and range corresponding to the identification code . The double rolling bearing is used as the support structure of the standard sensor and the measured sensor, which greatly reduces the impact of contact friction on the torque value, improves the measurement accuracy of the reference torque machine.
