Abstract:
1. A torque sensor for sensing torque in a rotatable shaft, wherein the rotatable shaft is configured to rotate within a shaft housing having an interior wall and an open end, the torque sensor comprising: a sensor housing at least partially circumscribing the rotatable shaft, the sensor housing having a first end, a second end, and at least one sensing zone; at least one target zone disposed on the rotatable shaft, wherein the at least one target zone is substantially opposing the at least one sensing zone; at least one bearing member disposed between the sensor housing and the rotatable shaft for limiting relative axial movement and allowing relative rotation between the sensor housing and the rotatable shaft; a first resilient member having a first end in contact with the first end of the sensor housing and a second end in contact with the interior wall of the shaft housing; and a second resilient member having a first end in contact with the second end of the sensor housing and a second end in contact with a retaining member connectable to the open end of the shaft housing.
