Title:
【発明の名称】非接触案内可能な磁気を用いた浮上装置
Document Type and Number:
Japanese Patent JP2568128
Kind Code:
B2
Abstract:
A simple-structured non-contact-guidable magnetic floating device which has stable restoring forces in vertical and horizontal directions perpendicular to the direction of guiding the moving member. At least one inner magnetic member is formed so that magnetic poles are continuously arranged in a lengthwise thereof. Two outer magnetic members are disposed on both sides of the inner magnetic member in adjacent but spaced relation thereto and formed so that magnetic poles are continuously arranged in a lengthwise thereof. A non-magnetic coupling member is provided apart from the inner magnetic member, for coupling together the two outer magnetic members. A support is provided for supporting and fixing one of the inner and outer magnetic members. The other of the inner and outer magnetic members is held in a floating state in which it has restoring forces to its center positions in vertical and horizontal directions, by magnetic attractive forces between the inner and outer magnetic members or a combination of their magnetic attractive and repulsive forces, and the other magnetic member can be guided in a lengthwise thereof in the floating state.
