    摘要： An improved magnetostrictive torque sensor for sensing torque applied to a shaft that is rotatably supported in a housing. A magnetostrictive cylinder is fixed to the shaft. A stator is supported on the shaft by bearings to surround the magnetostrictive cylinder and is accommodated in the housing. The stator incorporates exciting coils and detecting coils such that the coils are located about the shaft. The magnetosttrictive cylinder is strained by torque applied to the shaft. The exciting coils generate flux running through the magnetostrictive cylinder. The generated flux is changed in accordance with the strain of the magnetostrictive cylinder. The detecting coils detect the flux changes. The stator is also rotatably fixed to the housing by bearings. Rotation of the stator relative to the housing is prevented by connectors that couple the stator with the housing. This prevents tension in wires that lead from the stator.

    摘要： A sensor head is configured by beam-welding a magnetostrictive sleeve made of a magnetostrictive material to an intermediate sleeve. The intermediate sleeve is longer than the magnetostrictive sleeve. The intermediate sleeve protrudes from both ends of the magnetostrictive sleeve by a length "L". For the sensor head, an annealing process is performed. The sensor head for which the annealing process is performed is installed to a shaft. At this time, the contact portion between both ends of the intermediate material and the shaft are beam-welded all around.

    摘要： A torque sensing and strain detecting device that detects torque applied to a rotary shaft is described. The torque sensing and strain detecting device including a core made of a magnetostrictive material and at least two fastening sections fixed to the rotary shaft. A coil is wound around the core between the fastening sections. When torque is applied to the shaft, electromotive force is induced in the coil according to the strain produced in the core. Torque is detected based on the induced electromotive force.

    摘要： An inductive coupler for transferring electrical power from the primary to the secondary is disclosed. A secondary coil assembly having a pair of cores each having a secondary winding is disposed in a case having an opening at one end thereof. The core has a central post projecting from the axial center of a disc-shaped base and an annular skirt projecting from the rim of the base in the same direction, thus forming therebetween an annular groove in which the secondary winding is disposed. As a coil case having a primary winding is inserted between the paired cores and moved further inward of the case, the secondary coil assembly is moved inward of the case. During this movement of the secondary coil assembly, its paired cores are caused to displace toward each other while being guided by pins sliding along guide slits until the cores are mated together thereby to form a magnetic circuit of the inductive coupler. Provisions are also made to retain the secondary coil assembly in the position where the cores are closed and also to urge the secondary coil assembly toward the opening of the case.

    摘要： A magnetostriction type torque sensor has a magnetostrictive film formed on an outer peripheral surface of a rotary shaft, a coil having a coil centerline extending in a radial direction of the rotary shaft, and a signal processor responsive to coil impedance. Since the coil includes a coil centerline extending in a radial direction of the rotary shaft, magnetic fluxes are formed mainly in a radial direction of the rotary shaft. Accordingly, the magnetic fluxes intruding deep into the rotary shaft are decreased, and the rate of the magnetic fluxes passing through the magnetostrictive film is increased. As a result, the magnetostriction type torque sensor comes to have high sensitivity even when the rotary shaft has high magnetic permeability or high electric conductivity.

    摘要翻译： 磁致伸缩型扭矩传感器具有形成在旋转轴的外周面上的磁致伸缩膜，具有沿旋转轴的径向延伸的线圈中心线的线圈和响应于线圈阻抗的信号处理器。 由于线圈包括沿着旋转轴的径向延伸的线圈中心线，所以主要在旋转轴的径向上形成磁通量。 因此，进入旋转轴的深度的磁通量减少，并且通过磁致伸缩膜的磁通量的速率增加。 结果，即使当旋转轴具有高磁导率或高导电性时，磁致伸缩式扭矩传感器也具有高灵敏度。
