ABSTRACT:
Described herein is an improved torque analyzing apparatus for indicating the torque transmitted by power tools. In addition to the housing, bearing supports and torque indicator or pointer, the apparatus includes a torque input shaft that is frictionally connected with a torsion or spiral spring through a resilient sleeve on the shaft. The torsion spring is connected to and transmits torque to a spring housing which is connected to a torsion bar. The torque indicator or pointer is mounted on the spring housing. The torsion spring or spiral spring permits several rotations of the torque input shaft and provides a gradual increase in the torque that is applied to the torsion bar.
