Abstract

A rotor assembly for a multi-lobed trochoidal rotary engine, said assembly including a flat trochoid shape rotor which defines a bore by which the rotor is rotatably mounted on the crankpin of a crankshaft, and a steel hub, secured in the bore so as to project beyond one of the opposite side faces of the rotor, characterized in that the hub is mechanically inter-locked with the rotor in an arrangement which allows for differences in thermal expansion co-efficients of the rotor and hub, while substantially preventing relative rotation between the rotor and hub and substantially preventing radial separation of the rotor and hub.
