ABSTRACT:
A gas turbine, in which the rotor (9) of the power stage (5) is supported by a hollow shaft (10) in a cantilever fashion. The hollow shaft (10) has a pair of forged hollow frustoconical ends (11, 12) made of case-hardened and milled steel supported by bearings (19, 20, 20') and connected together by a hollow central tube (13). A stud (15) extends through and from the hollow shaft (10) and has threaded ends (15', 15"). The threaded end (15') releasably secures one end of the hollow shaft (20) into a correspondingly threaded portion (16) of the rotor (9) and the threaded end (15") is threaded into a nut (17) which cooperates with the other end of the hollow shaft (10) to releasably tighten the one end of the hollow shaft (10) to the rotor (9) and place the stud (15) under tension. The turbine also has a 3-cam system (26) which can be inserted into a circumferential groove (25) of the rotor (9) to centrally support the rotor (9) as the stud (15) is released, and gear means (22, 23, 24) for taking the drive from the power shaft (10) without increasing the bulk of the assembly.
