DETERMINING TORQUE IN A SHAFT

摘要

The present invention relates to an apparatus for determining torque in a shaft, the apparatus comprising an elongate member with a weakened region partway along its length, and means for securing the member to the shaft either side of the weakened region, preferably adjacent each end of the elongate member. The invention extends to a method of localising the twist a shaft undergoes, comprising securing an elongate member to a shaft, wherein the elongate member comprises a weakened region partway along its length.

主权项

1. An apparatus for determining torque in a shaft, the apparatus comprising:
an elongate member with a weakened region partway along its length weakened by a reduction in thickness in the shaft radial direction and/or with the weakened region having a lower shear modulus than the surrounding material; and a securing mechanism configured for securing the member to the shaft either side of the weakened region.
