Torque Application System
(2) The mechanical section of the torque application system is identified
in Figure 6 and is composed of the following components:
A torque lever.
A torque cell (SR-4 strain gage transducer.)
The torque wrench.
A stop and slider bar assemble (the stop is adjustable over the complete
length of the bar).
(3) The torque lever, which is the connecting link between the piston rod
and the torque cell, is pinned to the torque cell mount (a steel shaft-like piece
supported by a set of flange type ball bearings).
The torque cell is assembled
directly onto the mount while the square drive of the torque wrench fits into a
compatible opening in the top of the torque cell. The handle of the torque wrench
is positioned hard against the slider bar stop.
