ABSTRACT:
A torque detector comprising a first shaft and a second shaft, which are journalled in axially aligned and fixed relation with each other. A movable shaft is interposed between and axially aligned with the first and second shafts, the movable shaft being in axially slidable engagement with the first shaft and rotatable with the first shaft. The movable shaft is in rotatable threaded engagement with the second shaft, and springs are interposed between the movable and second shafts to resist and limit the axial movement and rotation of the removable shaft relative to said second shaft, whereby said axial movement depends on the torque being transmitted between the first and second shafts, when one of the first and second shafts is driven. The movable shaft is adapted to be connected to a transducer for determining the axial movement.
