Abstract

1,165,233. Bearings. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 8 Feb., 1968 [9 Feb., 1967], No. 6287/67. Heading F2A. In a magnet suspension for a rotating member comprising two annular magnet assemblies, one of which rotates and the other of which is stationary, at least the lowermost assembly is provided with a cover of non-magnetic material which covers the pole-face of an annular permanent magnet and extends at least partly across the space bounded by the pole-face. In an embodiment the upper polefaces of an annular permanent magnet 18, Fig. 2, is provided with a cover 26 of nylon and the lower pole-faces of an annular permanent magnet 15 is provided with a cover 23 of nylon. The cover 26, having a concentric wall 32, is press-fitted on to a core 16, an extension 20 of which is mounted in a frame 19. The cover 23, having an upwardly-extending wall 29, is press-fitted on to the outer surface of the upper magnet 15; and the cover 23 is provided with a downwardly-extending skirt 31. The magnet 15 is adhered to a flange 14 of a core insert 11, the latter is press-fitted on to a spindle 4 and has a bush 12 mounted therein which, along with a bush 22 mounted in the extension 20, supports a pintle 13. The covers 26, 23 are provided with holes 28, 27 respectively which receive the pintle 13 therein. In a modification a cover 37, Fig. 4, is press-fitted on to a lower magnet 18 which is adhered into an annular recess 36 of a body 20; and a cover 35 encapsulates an upper magnet 15. The cover 35, being provided with a hole 43, is pressfitted on to a spindle 4 and may be provided with a downwardly-extending skirt 48. Reference has been directed by the Comptroller to Specification 1,141,259.
