IPC: F16C32/06
Filed: 1990-11-21
Abstract: PURPOSE:To increase the accuracy and rigidity of a spindle by using a static pressure gas bearing for protective bearing and setting the sensitivity of an amplifying circuit in a control unit to the maximum limit at which the circuit is not saturated even if the main spindle is displaced at any position within rated permissible displacement limit of the static pressure gas bearing, to reduce a clearance between the bearings. CONSTITUTION:Stators 17 and 17a on which heat-proof, abrasion-proof ceramic collars 18 and 18a are fixed, respectively, are provided on both sides of a rotor for thrust magnetic bearing 16 near the center line of a spindle and ceramic coatings 19 and 19a are applied to the rotor 16.
