ABSTRACT:
A torque measuring device. The device comprises a mount base which is supported by a housing for swing motion around the axis of an output rotary shaft and for mounting an output rotary shaft-driving rotary machine thereon and whose center of gravity is located on the axis of a bearing assembly, a torque transmitting lever with its center of gravity located on the axis of its pivot for transmitting torque to a second lever, which second lever has a distal arm carrying thereon a moving coil disposed in a fixed magnetic field and is adapted to have a torque in the mount base transmitted thereto at its proximal point of action, and a position detector which detects the position of the moving coil and feeds its current output corresponding to a variation in the position of the moving coil back to the latter. This device is handy to carry.
