Title:
MAGNETOSTRICTION DETECTOR FOR MAGNETOSTRICTIVE TORQUE SENSOR
Document Type and Number:
Japanese Patent JPH0666651
Kind Code:
A
Abstract:
PURPOSE: To obtain a magnetostriction detector for torque sensor excellent in magnetic anisotropy and durability while having good characteristics of sensitivity, linearity, and the like.
CONSTITUTION: In the magnetostriction detector for torque sensor, a plurality of protrusions 3, inclining at an angle of 45° with respect to the longitudinal direction of a torque transmission shaft 1, are formed regularly on the outer surface of the shaft 1 with the width of the top surface of the protrusion 3 being set at 0.5mm or above and a magnetic alloy layer 4 is formed on the top surface of the protrusion.
