DEVICE FOR TEMPORARILY LOCKING ROTOR ONTO STATOR |
摘要 |
A device for temporarily locking onto a stator a rotor that normally rotates on the stator on magnetic bearings (such as an inertia wheel in a space satellite) includes a frustoconical bearing surface near the periphery of the rotor and a complementary frustoconical bearing surface on the stator. The rotor bearing surface is axially engaged with the stator bearing surface by a cable forming an annular loop in a transverse plane. A device is provided for releasing this cable. A plurality of radially mobile elementary bearing surfaces are coupled to the stator and there is a second bearing surface at the periphery of the rotor. These elementary bearing surfaces are axially engaged with the second bearing surface on the rotor, against the action of a return spring arrangement, in the direction opposite that in which the conical bearing surface on the stator applies an axial engagement force to the frustoconical bearing surface on the rotor. |
