Mouth, for connecting the tracheae of conveying high-pressure gas, lower permanent magnetism gas suspension bearing block（19）Stomata and lower footpath axial direction gas suspension axle
Hold（25）On valve align；Lower permanent magnetism gas suspension bearing axle sleeve moves magnet ring seat（18）, lower permanent magnetism gas suspension bearing determine magnet ring
Seat（21）It is placed on lower footpath axial direction gas suspension bearing（25）Terminal part and lower permanent magnetism gas suspension bearing block（19）On, it is dynamic to determine magnet ring（20）
It is placed on lower permanent magnetism gas suspension bearing axle sleeve accordingly and moves magnet ring seat（18）Determine magnet ring seat with lower permanent magnetism gas suspension bearing（21）In,
Adjust pad therein（22）Determine magnet ring for adjusting to move（20）Relative position gap；It is dynamic to determine magnet ring（20）Between repulsion be used for
Bear whole rotating part generator rotor shaft（3）The weight of upper rotor part, adjusting nut（23）For adjusting thrust disc（24）With
Lower footpath axial direction gas suspension bearing（25）Air gap between thrust face, due to lower footpath axial direction gas suspension bearing（25）Bearing capacity compare
Smaller, it only plays the auxiliary protection location control of footpath axial direction to generator amature system and bears radial centrifugal force, axial direction
