Abstract
A torque measurement system for measuring a torque acting on a rotatable shaft is provided. The torque measurement system includes a first housing portion having a first end adapted to be fixedly coupled to the rotatable shaft and a second end. The torque measurement system includes a second housing portion having a first end spaced apart from the second end of the first housing portion so as to define a gap between the first housing portion and the second housing portion. The second housing portion is adapted to be fixedly coupled to the rotatable shaft. The torque measurement system includes at least one sensor that observes at least one of the second end of the first housing portion, the first end of the second housing portion and the gap and generates sensor signals based on the observation. The sensor signals are indicative of a torque acting on the rotatable shaft.

27. A method comprising:
-
coupling a first housing portion coaxially about the rotatable shaft, such that a first end of the first housing portion is fixedly coupled to the rotatable shaft and the second end is free; coupling a second housing portion fixedly to the rotatable shaft such that the second end of the first housing portion is spaced apart from the second housing portion by a gap; and positioning a sensor adjacent to the gap, wherein the sensor is configured to observe at least one of the second end of the first housing portion, the second housing portion and the gap with the sensor, and wherein the sensor is further configured to generate sensor signals based on the observation, the sensor signals indicative of a torque acting on the rotatable shaft. - View Dependent Claims (28, 29, 30)
