Abstract:
1. A torque sensor comprising: an input shaft adapted to receive rotational force from a mechanical system; an input shaft gear attached to the input shaft; an output shaft; an output shaft gear attached to the output shaft; a torque gear adapted to be turned by the input shaft gear, the torque gear adapted to turn the output shaft gear; a pivot joint; a torque shaft pivotally attached to the pivot joint; a first end of the torque shaft connected to the torque gear through a torque gear bearing; and a second end of the torque shaft positioned to apply pressure to a load cell, wherein torque in the mechanical system causes the torque gear and, consequently, the torque shaft, to pivot about the pivot joint, causing the second end of the torque shaft to apply pressure to the load cell in proportion to the torque in the mechanical system.
