Document Type and Number:
Japanese Patent JPH0813185
Kind Code:
B2
Abstract:
PURPOSE:To regulate the unbalance of an inner cylinder during the rotation of a rotor by displacing the cylinder by a piezoelectric element or displacing a balance ring attached to the cylinder. CONSTITUTION:In a superconducting rotor, an outer cylinder 2 and an inner cylinder 3 are connected to a decoupling side rotary shaft 1, a coupling side rotary shaft 4 is further associated to form a concentric rotary shaft, and supported by a bearing base 5. The cylinder 3 has a field winding superconducting coil 6 and a cooling liquid helium 12, and gaseous helium is discharged while cooling the sections. In this case, a piezoelectric element 21 is held firmly between the cylinder 2 and the flexible coupling 13 of the end of the cylinder 3 in such a manner that it is slidable along the shafts 1 and 4 but immovable radially. Thus, a voltage is applied to the element 21 to bent the cylinder 3, thereby generating a displacement. As a result, a balance state is varied to suppress a vibration.
