Title (EN) MAGNETOSTRICTIVE TORQUE SENSOR SHAFT AND METHOD FOR MANUFACTURIN THE SAME
(FR) ARBRE DE COUPLEMETRE MAGNETOSTRICTIF ET SON PROCEDE DE FABRICATION
(JA) 磁歪式トルクセンサシャフトおよびその製造方法
Abstract: front page image
(EN)A torque sensor shaft for a magnetostrictive sensor in which magnetic shield characteristics are enhanced. The magnetostrictive torque sensor shaft (2) which comprises a fitting part (6) of a magnetostrictive detecting section (5) and a power transmitting shaft, wherein the torque sensor shaft (2) contains a magnetostrictive material and a para magnetic layer containing residual austenite is provided on the surface of a range including at least the fitting part (6) at the part excluding the magnetostrictive detecting section (5); and a method for manufacturing it.
(FR)L'invention concerne un arbre de couplemètre pour un capteur magnétostrictif dans lequel les caractéristiques de champs magnétiques sont améliorées. L'arbre de couplemètre magnétostrictif (2) comporte une partie de fixation (6) d'une section de détection magnétostrictive (5) et un arbre de transmission de puissance, l'arbre du couplemètre (2) contenant une matière magnétostrictive et une couche paramagnétique contenant une austénite résiduelle que l'on apporte sur la surface dont les dimensions permettent de recevoir au moins la partie de fixation (6) sur la partie excluant la section de détection magnétostrictive (5) ; ainsi que son procédé de fabrication.
(JA)本発明は、磁歪式トルクセンサ用のトルクセンサシャフトの磁気シールド特性を向上させる。具体的には、磁歪検出部5と動力伝達軸との嵌合部6とを備えた磁歪式トルクセンサシャフト2であって、トルクセンサシャフト2が磁歪材料を含み、上記磁歪検出部5を除く部分の少なくとも上記嵌合部6を含む範囲の表面に、残留オーステナイトを含む常磁性層を備えた磁歪式トルクセンサシャフト2とその製造方法を提供する。
