    • A nonintrusive, or noncontact, shaft torquemeter for use in measuring torque transmission through a rotatable shaft. The torquemeter includes an annular torque-sensing coil structure having an annular excitation coil and a pickup coil magnetically coupled to the excitation coil through an improved magnetostrictive coupling structure carried by the shaft. In the illustrated embodiment, the magnetostrictive coupling portion is provided on a tube coaxially fixed at its ends to the shaft. The invention comprehends the provision of structure for preventing a continuous annular conductive path through the coupling portion or tube. Other structure for improving torque measuring accuracy may be provided, including the use of an outer magnetic stator core, and the provision of annular corrugations in the tube for preventing transmission of nontorque forces, such as bending forces, to the coupling portion. In one embodiment, the coupling portion is defined by a portion of the mounting tube, and in another embodiment, the coupling portion is defined by a layer of magnetostrictive material on the tube.
    • 用于测量通过可旋转轴的扭矩传递的非侵入式或非接触式轴扭矩计。 扭矩计包括环形扭矩感测线圈结构,其具有环形激励线圈和通过由轴承载的改进的磁致伸缩耦合结构与励磁线圈磁耦合的拾取线圈。 在所示实施例中,磁致伸缩耦合部分设置在同轴固定在其端部上的管上。 本发明包括提供用于防止通过联接部分或管的连续环形导电路径的结构。 可以提供用于提高扭矩测量精度的其它结构,包括使用外部磁性定子芯,以及在管中提供环形波纹,以防止诸如弯曲力的非扭矩力传递到联接部分。 在一个实施例中,联接部分由安装管的一部分限定,并且在另一个实施例中,联接部分由管上的一层磁致伸缩材料限定。
