SYSTEM ZUM LOESBAREN VERBINDEN EINES ROTORKOERPERS MIT DER WELLE EINER MASCHINE
摘要
A system for disengageably coupling a rotor body to the shaft of rotary machines, in particular gas turbines and rotary dobbies, in which the coupling surface of said shaft is a cylindrical surface provided all the way round with longitudinal sharp-edged grooves of very small depth, they being uniformly distributed equidistantly to form a grooved cylindrical stub the interior of which comprises a frusto-conical bore cooperating with corresponding frusto-conical plug rigid with one end of a pull rod to lock the cylindrical coupling surface of the shaft against the cylindrical coupling surface of said rotor body by radial interference.
