COUPLING STRUCTURE FOR EXPANSION UNIT OUTPUT SHAFT AND DRIVEN-SIDE TRANSMISSION SHAFT

In an expander in which an energy of expansion of a vapor having a raised pressure is converted into a rotating energy for an output shaft, a cover member is mounted on an outer surface of a casing of the expander. The cover member has a function of sealing an end of the output shaft protruding on t...

Zusammenfassung:In an expander in which an energy of expansion of a vapor having a raised pressure is converted into a rotating energy for an output shaft, a cover member is mounted on an outer surface of a casing of the expander. The cover member has a function of sealing an end of the output shaft protruding on the outer surface of the casing against the outside and a function of recovering vapor discharged from the casing and having a dropped pressure after the conversion. The end of the output shaft located within the cover member and a transmitting shaft of a driven member disposed outside the cover member are connected to each other through a magnet-type shaft coupling, so that a power can be transmitted. Thus, the output shaft and the transmitting shaft of the driven member can be connected to each other to prevent the leakage of the vapor in the expander to the outside.
