PURPOSE:To prevent unsymmetrical wear of bearing by installing magnetic poles at the inner or outer periphery of two rotary bodies, and thus providing repulsive force and attractive force against the harmful attractive force and repulsive force of the rotary bodies, respectively. CONSTITUTION:Subsidiary magnet plates, a1, a1, and a2, a2', each having a uniform thickness, W1, W1' and W2, W2', and uniform magnetic polarity N, are installed circumferentially on the both ends of each rotary body 1, 2. With above installation, repulsive force, f1 and f1', are generated at a1 and a1' respectively, and the force, f1+f1', which is in reversed direction against the force F1 is imposed on the shaft of rotary body 1. In the same manner, repulsive force, f2 and f2', are generated at a2 and a2' respectively, and the force, f2+f2', which is opposite to the force F2 exerts on the shaft of rotary body 2. When relations ¦F1¦=¦f1¦+¦f1'¦and¦F2¦=¦f2¦+ ¦f2'¦is established, opposing of forces cancel each other, and no force exerts on the shafts of rotary bodies 1, 2. |
