PISTON MACHINE, SHAFT AND ANTI-FRICTION BEARING FOR A PISTON MACHINE

摘要

The invention relates to a piston machine comprising a housing, in which a shaft (19) is rotatably mounted in two pivot bearings. At least one pivot bearing comprises an inner ring (26a) that sits without radial displacement slippage on a support region (28) of a bearing section (19c) of the shaft (19). To prolong the service life of the pivot bearing or bearings the axial length of the support section (28) corresponds to a central region (a) of the bearing section (19c) and in both outer regions (b, c), radial displacement slippage takes place between the outer regions (b, c) and the inner ring (26a).
