Patent JP-2002357216-A (JP)
Title: Roller unit
Inventor: KITANO YOSHIO
IPC: F16C13/00
Filed: 2001-06-04
Abstract: PROBLEM TO BE SOLVED: To facilitate a deforming process and to aim unrestricted adjustment in a degree of its deformation when a rotating roller is deformed by means of magnetic force. SOLUTION: A peripheral surface of the freely rotating roller is set to be nonmagnetic and nonconductive. An alternating electromagnet is arranged to be independent from the roller in a fixed state so that magnetic poles are opposed each other in the peripheral surface of the roller. The roller is deformed along an axial direction by means of force of magnetic repulsion generated between the magnetic pole and the peripheral surface of the roller opposing to the magnetic pole. The force of magnetic repulsion being in inverse proportion to the square of the length of an air gap, the force of magnetic repulsion becomes greater when the air gap between the peripheral surface of the roller and the magnetic pole is shorter. Further, the force of magnetic repulsion can be freely adjusted by supplied electric power to an alternating electromagnet.
