Flying wedge (centripetal retractor) assembly

摘要

The flying wedge clutch assembly is a speed actuated coupling device that provides low speed axial load and torque transmission and disengages for increased shaft motion at higher speeds. The flying wedge clutch assembly is a compact and lightweight design, roughly equivalent to a conventional ball bearing assembly in a typical turbopump application. Advantageously, the flying wedge clutch assembly can be used in high speed rotating machines with radial hydrostatic bearings eliminating the speed and life limitations normally attributed to rolling element bearings.
