Pressure build-up process involves sending fluid by means of feed device from rotating store to intermediate cavity

摘要

The pressure build-up process for couplings (1) between co-axial machine elements such as a shaft (2) and a hub (3) involves using a coupling with an intermediate cavity (4) bounded by a wall (6) having an elastic region (7). During the rotation of the coupling, the fluid is send by at least one feed device (12) from a fluid store (11) rotating with the coupling to the intermediate cavity.
