摘要 <p>1,224,496. Hydrodynamic bearing. PHILIPS' GLOEILAMPENFABRIEKEN N.V. 28 March, 1968 [31 March, 1967], No.14985/68. Heading F2A. A hydrodynamic bearing for a shaft 1 has a part-spherical member 2, fixed to the shaft, located in a cavity in a housing 3 which forms a co-operating bearing surface, either the member 2 or the surface of the housing 3 having two sets of shallow grooves 6 regularly distributed around the surface, the centre line of each groove of each set being a loxodromic spiral, and the grooves of each set being arranged on relative rotation of shaft and housing, to urge lubricant over the bearing surfaces towards the other set of grooves. Annular grooves 8 may be provided on the side of each set remote from the other set to form lubricant chambers. Further patterns of grooves 10 may be provided on the side of the chambers 8 remote from the other grooves, to prevent leakage of lubricant.</p>
