Abstract
Abstract A compliantly mounted damper (16,18) for rotating equipment of the type including a rotor shaft (2) and a quill shaft (6) coupling the rotor shaft (2) to a driver shaft (8) is disclosed. The damper includes a plate (14) rigidly mounted to the quill shaft (6) and a plate (16) compliantly mounted to the rotor shaft (2) so that the rotor shaft plate (16) follows the angular displacement of the quill shaft plate (14) due to shaft misalignment which may occur, while torsional damping is achieved.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
133 words
Compliantly mounted damping means for rotating equipment of the type including a rotor shaft and a quill shaft coupling the rotor shaft to a driver shaft, characterized by: a first plate rigidly mounted to the quill shaft; a second plate having a conical bore; the rotor shaft having a conical tip which fits snugly into the conical bore; means for compliantly mounting the second plate to the rotor shaft including an elastomeric member disposed within the conical bore; means for providing an axial load, whereby the first and second plates are maintained adjacent each other to provide torsional damping; and the means for compliantly mounting the second plate to the rotor shaft permitting the second plate to follow the angular displacement of the first plate occurring due to misalignment between the respective shafts.
Claim 2
Dependent Claim
133 words

Claim 3
Dependent Claim
21 words
Compliantly mounted damping means as described by claim 1, further characterized by: the elastomeric member being bonded within the conical bore.
Claim 4
Dependent Claim
35 words
Compliantly mounted damping means as described by claim 1, further characterized by: the means for compliantly mounting the second plate to the rotor shaft being effective as a torsional resilient member to provide torsional damping.
Claim 5
Dependent Claim
35 words
Compliantly mounted damping means as described by claim 1, further characterized by: the means for compliantly mounting the second plate to the rotor shaft being effective as an axial resilient member to provide axial damping.
