摘要： To obtain stable linear torque-output characteristics over a wide torque range in a magnetostrictive torque detecting apparatus having a shaft to be measured, an exciting coil for magnetically exciting the shaft, and a detecting coil for detecting magnetostrictive components generated in the shaft distorted by a torque, the shaft is particularly composed of a substrate shaft portion made of a high yield point material and a shape anisotropic layer portion made of a high magnetostrictive material metallographically welded on an outer surface of the substrate shaft. The welded shape anisotropic layer portion is formed with two symmetrical groups of concave/convex portions each arranged at regular angular intervals on the outer circumferential surface thereof at an inclination angle with respect to the axial direction of the shaft.

摘要： PURPOSE:To obtain a magnetostriction measuring member which has large accepting torque and shows high sensitivity to the magnetostriction by providing a specific band-shaped thick layer in the outer periphery of a steel shaft material made of carbon steel or alloy steel. CONSTITUTION:The magnetostriction measuring member uses a steel shaft material made of carbon steel or alloy steel. For the carbon steel, SC material, S-CK material, etc., is employed. For the alloy steel, e.g. SCr material, SMn material or the like which is a kind of steel for mechanical structure is used. A band-shaped thick layer formed of Fe-Al alloy containing 1-50wt.% Al is provided on the surface of the shaft material. If the content of Al is too small, the hysteresis is greatly varied when the torque is detected. Therefore, the content, of Al is set to be not smaller than 5wt.% Moreover, if Al is contained too much, the sensitivity is lowered, and therefore the content should be 15wt.% or lower so as to increase the detecting sensitivity. When the band-shaped thick layer is too thick, it cracks, and therefore, the band-shaped layer is 3mm thick or thinner. Further, if the layer is too hard, it also generates cracks, and therefore the layer is adapted to have Vickers hardness Hv=420 or smaller.

摘要： PURPOSE:To make it possible to detect torque stably from low torque to high torque by exposing a substrate-material part at the bottom part of each recess part formed at a high magnetostriction part, expanding the range of substrate materials which can be utilized, and positively providing a high yield point in the substrate material. CONSTITUTION:In a shaft to be measured 2, a material, which has a high yield point by surface hardening, is used as a substrate 2a. A high magnetostriction material 2b is fused on the surface as a metal texture. A plurality of recess parts 3a and 3b are formed in the circumferential directions at the symmetrical left and right sides at specified angles with respect to the direction of the axial center of the shaft 2 at the part of the material 2b. Protruding parts 4a and 4b are relatively formed in this way, and a magnetic anisotropy part in shape is provided. Coils 5a and 5b are arranged at the outer surface parts of the shaft 2 so as to face the magnetic different- direction part. At this time, the recess parts 3a and 3b occupy the broad range of the part of the material 2b. The substrate material is exposed at the bottom part in this constitution. Thus, the range of the substrate material, which can be utilized as the shaft to be measured, can be expanded, and the stable torque detection can be performed.
