<p>PURPOSE:To provide a shape measurement roller which can measure a degree of evenness of a rolled plate produced by a rolling mill. CONSTITUTION:A stator 23 on a stator core 25 wound with a coil 26 is fixed on a fixed shaft 23 as another stator of a radial magnetic bearing, and a rotation roller 29 including a rotor 27 opposed thereto is provided. A gap sensor 28a for detecting a clearance between the rotor 27 and the stator 24 is provided to be opposed to a rotation roller 29 in the side of the stator 24. Thereby a shape measurement roller of a unit is constituted, a plurality of the shape measurement rollers are provided in accordance with the width of products and each shape measurement roller is supported in the direction of thrust due to the face pressure of a slide member 31. However, a thrust magnetic bearing composed of another rotor 36 and the other stator 37 on a stator core 33 wound with another coil 35 is provided for the shape measurement rollers of the both ends.</p> |
