Abstract
A torque measuring apparatus is described that comprises: (1) a pair of parallel flexible mechanical beams mounted in like cantilever fashion on a chassis; (2) a torque-transmitting shaft rotatably mounted to the chassis; (3) a force-transmitting arm having a first end attached to the torque-transmitting shaft so as to rotate therewith and a second end extending between and adjacent to said beams; (4) an encoder having a rotatable input shaft coupled to said torque-transmitting shaft so that rotation of said torque-transmitting shaft will cause rotation of said input shaft; and (5) means on said torque-transmitting shaft for coupling said torque-transmitting shaft to one component of an aritcle to be tested, e.g., the screw cap on a tube or bottle, whereby a torque applied to said one component is transmitted to said torque-transmitting shaft. The applied torque causes the torque-transmitting shaft to act via the force-transmitting arm to bend one or the other of the two beams, according to the direction of rotation of said shaft. The encoder translates the rotation of the torque-transmitting shaft into an electrical output that varies as a function of the applied torque. Additiona…
