Amortisseur Winding Arrangement, In A Rotor For Electrical, Rotating Equipment

US Patent:
5550417, Aug 27, 1996
Filed:
Jul 3, 1995
Appl. No.:
8/497972
Inventors:
Darrell R. Morrison - Blaine MN
James L. Nessa - St. Paul MN
James J. McClurg - Vadnais Heights MN
Assignee:
Dresser-Rand Company - Corning NY
International Classification:
H02K 316, H02K 3487
US Classification:
310183
Abstract:
Electrically-conductive, segmental, slot wedges, with electrically-conductive inserts therebetween, and electrically-conductive interconnects, between end ones of the wedges and the annular, end retaining ring, of a rotor, define an amortisseur winding for the rotor. The inserts are spring-loaded in end slots formed in the wedges, and in an embodiment of the invention, are formed of beryllium copper and are silver-plated. As is typical of rotors in electrical, rotating equipment, the slot wedges are formed of aluminum.

Amortisseur Winding Arrangement, In A Rotor For Electrical, Rotating Equipment

US Patent:
5606211, Feb 25, 1997
Filed:
May 8, 1996
Appl. No.:
8/646578
Inventors:
Darrell R. Morrison - Blaine MN
James L. Nessa - St. Paul MN
James J. McClurg - Vadnais Heights MN
Assignee:
Dresser-Rand Company - Corning NY
International Classification:
H02K 100
US Classification:
310182
Abstract:
Slot wedges, electrically-conductive, used in rotor slots, between rotor teeth, and overlying the rotor coils, are serially arranged in the slots and have arcuate grooves in opposite ends thereof. Inserts, also electrically-conductive, are spring-loaded in the grooves to effect electrical continuity fully therealong, lengthwise of the rotor, from wedge to wedge.

Spherical Roller Bearing Assembly

US Patent:
5207512, May 4, 1993
Filed:
May 6, 1992
Appl. No.:
7/880150
Inventors:
Jerome D. Grant - Brooklyn Park MN
Wayne M. Svegal - Brooklyn Park MN
James J. McClurg - Vadnais Heights MN
Assignee:
Dresser-Rand Company - Corning NY
International Classification:
F16C 1938
US Classification:
384464
Abstract:
A spherical roller bearing is confined in a bearing ring which, in turn, is confined in a bearing housing, the housing and the ring each being of split construction. The housing has a pair of il reservoirs therein separated by a saddle upon which the ring is mounted, and an anti-rotation pin engages both the housing and the ring to prohibit rotation of the latter in the former. The ring, too, has an oil reservoir therewithin. The ring and pin, and accordingly the bearing, are electrically isolated from the housing. An oil ring rides upon a bearing-mounted motor shaft through slots formed in the bearing ring, and is guided by machined reliefs formed in opposite sides of the bearing ring. Holes in the saddle provide for a through-flow of oil between the pair of reservoirs in the housing.
