Production method and magneto-striction type torque sensor of magneto-striction type torque sensor

摘要

Topic The magnetic material free form and being possible in the axial material of the axis of rotation to form with thickness, production method of the magneto-striction type torque sensor which can obtain the magneto-striction type torque sensor whose sensitivity is high is offered. SolutionsIn the peripheral aspect of the axial material of axis of rotation 1, as in the territory where magnetostriction detection layer is not formed, photo-curing resin 11b is formed after making the part harden which the photo-curing resin formation hardening process which is made to harden and the optical non- transmitted section in the aforementioned photo-curing resin excludes, spraying the magnetic material on the peripheral aspect of the axial material of concave section formation process and the axis of rotation, 1 which form the concave section in the part which excludes the hardening section in the peripheral aspect of the axial material of the axis of rotation the magnetostriction detection layer flame spraying process which forms magnetostriction detection layer 2a and 2b in the aforementioned concave section and,It possesses. According to this method, forming magnetostriction detection layer 2a and 2b thickly, it becomes possible to obtain the magneto-striction type torque sensor whose sensitivity is high.
