DOUBLE DIAPHRAGM COMPOUND SHAFT

摘要

A compound shaft coupling having a flexible disk shaft, with two flexible disks or diaphragms, and a tie bolt shaft connecting two rigid or stiff shafts. One flexible disk dia phragm of the flexible disk shaft is coupled with an interference fit to the first stiff shaft , while the other flexible disk diaphragm of the flexible disk shaft is coupled with an interferen ce fit to the tie bolt shaft which removably mounts the second stiff shaft. A quill shaft connects the two flexible disk diaphragms of the flexible disk shaft. The first stiff shaft can b e a hollow sleeve with a magnet mounted therein and the second stiff shaft or power head shaft may include a compressor wheel, a bearing rotor, and a turbine wheel removably mounted on the tie bolt shaft.
