Abstract

1,175,465. Bearings. COMMISSARIAT A L'ENERGIE ATOMIQUE. 6 May, 1968 [17 May, 1967], No. 21276/68. Heading F2A. A hydrodynamic fluid bearing comprises a resiliently-mounted bush 1 with a smooth bore enclosing a shaft 3, the outer surface of which contains troughs 16 equispaced about its axis. The depth of each trough may decrease constantly around the periphery of the shaft (Fig. 2, not shown). The resilient mounting may be as described in Specification 1,111,362. The bush may have a P.T.F.E. lining 2.
