Curvic coupling enveloped half pitches
WebDec 1, 2024 · Curvic couplings were first developed by Gleason Works in 1942 [1]. Due to the self-centering and strong load-carrying capacity of curvic coupling, it is widely used in the fixing and connection of multistage rotors in aero-engines [2]. Fig. 1 shows the schematic diagram of the gas generator rotor of a type of turboshaft engine. WebBack to Basics - Free download as PDF File (.pdf), Text File (.txt) or read online for free.
