Abstract
1514132 Rotary positive-displacement fluidmachines ROBERT BOSCH GmbH 11 March 1976 [14 March 1975] 9814/76 Heading F1F In a gear pump, or motor, shafts 20, 21, 27, 28 for the gears 22, 29 are mounted in bearing bushes 18, 19, 25, 26 that are accommodated in bearing members 16, 17, 23, 24 with substantial radial clearance so that they are free to revolve therein and thus wear uniformly, the life of the bearings being therefore extended. The bushes may be made of white metal and the shaft journals and bearing members of a harder material such as steel. Alternatively, the bushes may have outer layers of harder material e.g. brass or steel, the bearing members then being made of a soft bearing material, Fig. 4 (not shown). Rings or flanges may be provided to retain the bushes in the bearing members, Figs. 5 and 6 (not shown).
