Abstract

A torque measurement system (201) is provided and includes a first shaft (210) to rotate by input torque, a second shaft (220) to rotate by torque received from the first shaft, the second shaft including first lugs (221), a reference shaft (230) including second lugs (231) and being connected to the first and second shafts via spline and helical spline connections (232, 233), respectively, an elastic element (240) to oppose a reaction force of the helical spline connection to axially displace the reference shaft resulting in reference shaft twisting due to the helical spline connection and a measurement system (250) to measure angular displacement between the first and second lugs due to the reference shaft twisting.
