ABSTRACT:
A rotor is distinguished by parts including a radially innermost part and a radially outermost part which is actually a separate element. The two parts are normally coupled for their conjoint rotation by pins anchored to project radially from the innermost part and freely into apertures in the radially outermost part. The pins provide a bearing mount thereon of the outermost part which is fabricated to radially expand and contract in correspondence with the speed of rotation of the rotor and to have a benign failure in the location of one of the apertures upon excessive speed of the rotor. By virtue of such failure the radially outermost part opens and expands to be braked by engagement with the particular surface most adjacent its outer periphery. This rotor is particularly advantageous for use in providing a turbine drive unit, in which event its power transmitting outer peripheral portion is formed by turbine buckets.
