1,156,537. Bearings. PHILIPS' GLOEILAMPENFABRIEKEN N.V. 13 July, 1966 [16 July, 1965], No. 31502/66. Heading F2A. In a fluid thrust bearing, spiral grooves 6, Fig. 2, are formed in one side of a thin metal plate 5, the other side of which is secured to a member 3, Fig. 1. The grooves 6 have a depth which is about one-fifth the thickness of the plate 5 and are formed by etching. The plate 5 is provided with two tags 7 which may be bent-over and held in recesses in the member 3, which may be made of a synthetic resin; alternatively, the plate may be secured by the tags to the member 3 by welding. The member 3 is square-shaped, is mounted within four lugs 2 of a stationary member 1, and is provided with a part-spherical shaped protrusion 4 which effects self-aligning thereof. In a modification, the plate 5 may be secured to a shaft 9. |
