Abstract

1451487 Rotary positive-displacement fluidmachines DANFOSS AS 28 Nov 1973 [2 Dec 1972] 55205/73 Heading F1F In a gerotor-type machine, which may be a pump or a motor, the teeth of a fixed ring 6 co-operating with a planetary toothed wheel 12 are constituted by rollers 15, which engage with recesses 28 in a member 13, the line of contact Y between each roller and the wheel being co-linear with the line of contact X between the roller and the said member. This arrangement is said to reduce wear. A shaft 16 coupling the wheel 12 to an input, or output, shaft 9 has a splined head 17 and strip-like portion 16 engaging with an opening 20 in the wheel. A bore 30 may be provided in the member 13 so as to accommodate an end 19 of the shaft portion 16.
