摘要： A rotatable hub in which a supporting shaft having hydrodynamic pressure generating grooves is inserted comprises an annular thrust bearing plate in its lower portion and annular permanent magnets in its upper portion. The thrust bearing plate is inserted between the lower end face of the supporting shaft and a thrust flange fixed to the supporting shaft, maintaining the respective clearances D and E. The permanent magnets on the hub are confronting in such a manner that an upward and downward repulsive forces are generated between permanent magnets mounted on the supporting shaft, respectively maintaining the clearances B and C. Since the clearances B and C are greater than the clearances D and E, the permanent magnets will not mutually contact even when the hub is caused to move upward or downward by an external force during rotation and the thrust bearing plate contacts with the lower end face of the supporting shaft or the thrust flange.

摘要： A magnetic bearing system contains magnetic subsystems which act together to support a rotating element in a state of dynamic equilibrium and dampen transversely directed vibrations. Mechanical stabilizers are provided to hold the suspended system in equilibrium until its speed has exceeded a low critical speed where dynamic effects take over, permitting the achievement of a stable equilibrium for the rotating object. A state of stable equilibrium is achieved above a critical speed by use of a collection of passive elements using permanent magnets to provide their magnetomotive excitation. In a improvement over U.S. Pat. No. 5,495,221, a magnetic bearing element is combined with a vibration damping element to provide a single upper stationary dual-function element. The magnetic forces exerted by such an element, enhances levitation of the rotating object in equilibrium against external forces, such as the force of gravity or forces arising from accelerations, and suppresses the effects of unbalance or inhibits the onset of whirl-type rotor-dynamic instabilities. Concurrently, this equilibrium is made stable against displacement-dependent drag forces of the rotating object from its equilibrium position.

A magnetic cylindrical bearing is inserted into the magnetic hollow rotating shaft such that a radial repulsive force is generated between the magnetic hollow rotating shaft and the magnetic bearing. A first fixed magnetic member is disposed at a top of the magnetic cylindrical bearing, and a rotating magnetic member is disposed at a top of the magnetic hollow rotating shaft such that the magnetic hollow rotating shaft can be supported by axial repulsive force generated between those magnetic members. The magnetic members are vertically adjustable for varying the axial clearance therebetween.

摘要： A magnetic bearing is disclosed for an open-end spinning rotor having a shaft supported in a wedge-like gap formed between at least one pair of support rollers. The bearing comprises a housing for receiving the shaft, a magnet disposed in the housing to extend radially relative to the shaft, and a magnet disposed on and radially extending from the shaft axially adjacent and at a spacing from the magnet in the bearing housing. The magnets have respective poles of the same magnetic orientation disposed to face and thereby repel one another. According to the invention, a coupling connects the shaft and the magnet disposed on the shaft, the coupling being releasable in response to an axial force exerted on the shaft.

摘要： An optical deflector for deflecting a laser beam from a laser by rotating a polygon mirror uses a dynamic pressure pneumatic bearing as a radial bearing and a magnetic bearing as a thrust bearing. The deflector includes a hollow rotor rotatable integrally with the mirror, a stationary shaft received in said hollow rotor, a casing member accommodating the rotor and stationary shaft, and an annular rotor magnet assembly mounted on the outer periphery of the rotor. A first rotary magnet is mounted in an upper end portion of a rotary shaft and a first stationary magnet in an upper end portion of the stationary shaft in such a manner as to face each other with the same polarity, a repulsive force acting between the two magnets serving as a thrust magnetic bearing. A second stationary magnet is arranged to face the first rotary magnet with the same polarity. Further, a second rotary magnet is mounted in a lower end portion of the rotary shaft and a third stationary magnet in a lower end portion of the stationary shaft in such a manner as to face each other with the same polarity.

摘要： A repulsion-type permanent magnet bearing system for watthour meters includes identical upper and lower permanent magnet assemblies. Each assembly includes a hollow cylindrical magnet including a temperature compensating sleeve extending through each magnet center opening. Soft magnetic shielding cups are attached to the rotor and stator parts of the meter to carry the permanent magnet assemblies in facing relationships. The permanent magnet size and orientation with respect to each other and the cups provides an optimumly maintained bearing gap spacing.
