摘要： The end surface 2e of the press-fit portion 2c of the axle 2 is machined with high precision to serve as a reference surface for measuring the negative bearing clearance upon completion of the assembly. The inner ring 3 is press-fitted on the press-fit portion 2c of the axle 2 and is fixed in position by the nut 6 screwed on the threaded portion 2d of the axle 2. In this axle bearing assembly, the inner ring 3 abuts against the shoulder portion 2d of the axle 2 with no clearance defined therebetween, and the negative bearing clearance is assured.

摘要： A turbo pump is disclosed, having a magnetically supported impeller. The turbo pump includes a casing (31) made of a non-magnetic material, an impeller (32) provided in the casing (31), a triaxial controlled magnetic bearing provided outside of the casing (31) for magnetically supporting the impeller (32), and a rotor (37) magnetically coupled to the impeller (32) for rotating the impeller. The triaxial controlled magnetic bearing includes a magnetic member (35) provided on one plane of the impeller and a plurality of electromagnets (39) provided in the casing in such a way as to be opposed to the magnetic member. Coupling between the impeller (32) and the rotor (37) is effected by a plurality of permanent magnets (33, 38) respectively provided thereon. In another aspect of the invention, a plurality of stator windings for generating the rotating magnetic field may be provided on the side of the stator in place of rotating means utilizing a magnetic coupling.
