Abstract
A flexible coupling assembly for a power transmission system including a first shaft defining an axis, configured for connecting to a first rotating member, the first shaft adjoining and passing through a first flexible diaphragm coupling and lockably connecting to a quill shaft by a locking flange and the quill shaft being configured for connecting to a second rotating member, including a first mating portion for receiving the locking flange of the first shaft within a circumferential opening, wherein the quill shaft is disposed within a primary diaphragm coupling shaft.
Claims12
A flexible coupling assembly for a power transmission system comprising:
- a first shaft defining an axis, configured to connect to a first rotatable member;
- a first flexible diaphragm coupling configured to have a portion of the first shaft pass axially therethrough;
- a quill shaft having a circumferential opening configured to receive the first shaft and receive a locking flange of the first shaft for connecting the quill shaft to the first shaft, the quill shaft further being configured to connect to a second rotating member;
- a primary diaphragm coupling shaft positioned radially outward of the quill shaft;
- and
- at least one flange adapter disposed between the primary coupling shaft and the first flexible diaphragm coupling, wherein the flange adapter is welded to the diaphragm coupling, and wherein the at least one flange adapter includes a pin hole there through arranged perpendicular to the axis and aligned with a pin hole of the first shaft for receiving a pin therein configured to lock relative movement of the first shaft and the flange adapter, wherein the locking flange includes at least one radial protrusion for mating with a cutout within a first mating portion of the quill shaft.
