Geometric array structure of the magnetic levitation power in the magnetic levitation type rotary bearing device

摘要

(57) Abstract Topic Vacuum turbo numerator pump, principal axis of high-speed machine toolAnd in practicality in order to apply to the inertial gyro compass and the likeThe magnetism which was rich, in the magnetic levitation type rotary bearing device of the optimumStructure of arrays surfacing power geometric is offered. Solutions In magnetic levitation type rotary bearing device of this deviceAs for structure of arrays ke ru magnetic levitation power geometric, in prophase bearing equipmentTurning the principal axis with the magnetic force which the position is done, power and in order to surfaceTo do, having in radial module, the principal axis and verticality, at the same time the main thingTo be agreeable to the axis and to supply two magnetic levitation forces of constraints cap, and the axisBeing parallel with the principal axis which direction module supplies, at the same time kopuranaTo supply three magnetic levitation forces of constraints which are not formed, motion geometryFrom study viewpoint, as for this feature the force of constraint where five line of total becomes independentTo possess, surfacing the principal axis, element and contact of standstill andIt does not graze, the surfacing power which is stabilized on that, with axial direction offering/accompanyingAs for the effect of providing former magnetic levitation type rotary bearing compared to being superiorThe te it is. As for the principal axis Drive with the rotary motor, rotation of high speedTo do, wear to be little, because noise also the vibrations are few, highFor example fast rotary machine vacuum turbo numerator pump, high-speed machine toolIt is applied to the principal axis and the inertial gyro compass etc.
