Auto Measure about Mechanical Efficiency of Lathe Gearshift Device

摘要

The article introduces how to use compound sensors of photoelectric potentiometer and resilience axle sensor. By measure the turn angle in opposite cross section at a length L of resilience axle. And pass through photoelectric transform to measures output voltage of sensors, according to output voltage to measure torque of output axle (or input axle), and then measure development mechanical efficiency of lathe gearshift device.
