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

Title:

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

Document Type and Number:

WIPO Patent Application WO/2001/033048

Kind Code:

A1

Abstract:

An expansion unit (4) for converting an expansion energy of pressure-increased steam into a rotation energy of an output shaft, wherein a cover member (26) is provided on the casing outer surface of the expansion unit (4). The cover member (26) has a function of sealing the end section of an output shaft (23) protruding beyond the casing outer surface against the outside and a function of recovering steam led out from the casing and has its pressured reduced after the conversion. The end section of the output shaft (23) provided inside the cover member (26) and a driven-side transmission shaft (119) disposed outside the cover member (26) are coupled with each other via a magnet type shaft coupling (120) so as to be able to transmit power, whereby the output shaft (23) and the driven-side transmission shaft (119) can be coupled without steam in the expansion unit leaking outside.
