TORQUE ADAPTER

A torque adapter for measuring a stall torque supplied by a rotary power source includes a housing, a mandrel rotatable relative to the housing, and a resistance subassembly. The housing includes an arcuate recess defined at least partially by a recess front wall and a recess back wall. The arcuate...

Zusammenfassung:	A torque adapter for measuring a stall torque supplied by a rotary power source includes a housing, a mandrel rotatable relative to the housing, and a resistance subassembly. The housing includes an arcuate recess defined at least partially by a recess front wall and a recess back wall. The arcuate recess includes a first rotational zone bounded on one side by the recess front wall, and a second rotational zone bounded on an opposite side by the recess back wall. The mandrel includes a flange portion having an arcuate protrusion received in the arcuate recess. The resistance subassembly includes a biasing member and is received into the arcuate recess. When the mandrel is rotated relative to the housing, the mandrel encounters nominal rotational resistance while the arcuate protrusion passes through the first rotational zone, and the mandrel encounters increasing rotational resistance while the arcuate protrusion passes through the second rotational zone.
