Abstract:
A shaft joint has an inverse conical stopper. The joint is a combination of interconnected shafts, with one shaft being inserted into the other. The interface between the two shafts can be of any type: press-fit, thermally shrank, threaded, etc. Besides, the shaft-to-shaft interface can be also either bonded or non-bonded.

Claim (Index 1):
A micro-turbine based turbogenerator comprising:\n a turbine shaft having a turbine impeller mounted thereupon; a compressor shaft having a compressor impeller mounted thereupon, the compressor shaft having an end part with a reduced cross section that is separated from the rest of the compressor shaft via a step; a generator rotor fixedly mounted on the turbine shaft, the generator rotor having a hollow sleeve formed opposite the turbine shaft for receiving the reduced cross section of the end part of the compressor shaft; and wherein the step has a surface that forms an inverse conical shape, and the hollow sleeve having a butt end with an end surface which abuts the surface of the step at an incline relative to a centerline of the compressor and turbine shafts to prevent expansion of the hollow sleeve during rotation of the compressor and turbine shafts.
