Bearing Wear Detection System
US Patent:
6100809, Aug 8, 2000
Filed:
Nov 24, 1998
Appl. No.:
9/200379
Inventors:
Yefim Novoselsky - Old Bridge NJ
Samuel Hsieh - Marlboro NJ
Ratan Guha - Oakhurst NJ
Muthu Murugan - Howell NJ

Assignee:
AlliedSignal Inc. - Morristown NJ
International Classification:
G08B 2100
US Classification:
340682
Abstract:
A bearing detection system for an electrical generator (10) includes auxiliary bearings (29) for supporting a rotating shaft (39) upon failure of main bearings (62). The auxiliary bearings (29) are mounted on the shaft and have a slight gap (64) between their outside diameters and bearing liners 33. The gap corresponds to the main bearing permissible wear. During normal functioning of the main bearing, the auxiliary bearing frame (34) rotates with the shaft and a magnet (35) with a small clearance between its face and auxiliary bearing outer ring (32) forces the synchronized rotation of inner (37) and outer (32) races. The auxiliary bearing outer ring or race (32) has a coaxial groove (31) on its outer diameter and a detection sensor (30), mounted on the bearing liner, gives a signal per rotation of the shaft to a control circuit (40). The control circuit (40) determines the rotational status of the auxiliary bearings outer ring (32) by counting the number of impulses generated by the circuit (40) when the groove crosses the sensor's magnetic fields. The circuit (40) detects the moment when any auxiliary bearing comes in contact with the bearing liner and results in no impulses being generated.
Rotor Assembly Having Lamination Stack That Is Separately Piloted And Clamped
US Patent:
6122817, Sep 26, 2000
Filed:
Sep 19, 1997
Appl. No.:
8/933820
Inventors:
Walter Lee Meacham - Phoenix AZ
Reinhard Manfred Klaass - Phoenix AZ
Leon M. Kasdan - West Long Branch NJ

Assignee:
AlliedSignal Inc. - Morristown NJ
International Classification:
H02K 1502
H02K 106
H02K 106
US Classification:
29598
Abstract:
A rotor assembly includes a lamination stack, a pilot shaft for providing radial piloting for the lamination stack, and clamp for applying an axially compressive force to the lamination stack. Decoupling the piloting from the clamping allows the diameter of the rotor assembly to be increased. Resulting is a rotor assembly having a shorter axial length and higher tip speed.
