Abstract:
A torque wrench is provided. The torque wrench has housing and a rotating assembly rotatably mounted in the housing. The rotating assembly has a gripping assembly with an aperture for receiving a tubular and a plurality of die assemblies; a bevel pinion carrier assembly with a bevel pinion carrier and a bevel pinion mounted in the bevel pinion carrier; an upper ring gear fixed to an upper bevel gear rotatably connected to the bevel pinion at an upper side of the bevel pinion carrier; a lower ring gear fixed to a lower bevel gear rotatably connected to the bevel pinion at a lower side of the bevel pinion carrier; and first and second members threadably coupleable with each other, the first threadably coupleable member fixedly connected to the bevel pinion and the second threadably coupleable member drivingly connected to the die assembly, wherein rotation of the bevel pinion drives the die assembly toward and away from the tubular.
