Self-Aligning Bearing
US Patent:
4256353, Mar 17, 1981
Filed:
May 18, 1979
Appl. No.:
6/040163
Inventors:
George A. Fischer - Boxford MA
Melvin A. Prohl - Boxford MA
Melvin A. Prohl - Boxford MA
Assignee:
General Electric Company - Lynn MA
International Classification:
F16C 2304, F16C 2702, F16C 3502
US Classification:
308 26
Abstract:
In large turbine machines, it is critical to bearing performance that the turbine rotor remain aligned with the bearing surfaces. Misalignment can occur due to high thrust loads or thermal deformation. The object of the invention is to ensure correct rotor-bearing alignment under all operating conditions. The invention is a self-aligning bearing support structure capable of accommodating angular rotor misalignments. The bearing support structure includes a bearing casing which transfers axial loads or thrusts to the bearing standard through a yoke attached to the bearing casing and to the bearing standard by pairs of axially oriented flex struts. In combination with the axially oriented flex struts a transverse flex plate supports the bearing vertical load.

Abstract:
A heat exchanger includes a number of fluid carrying tubes disposed in a hot gas flow path. One arrangement of heat exchanger tubes includes a plurality of finned serpentine tubes parallel to one another and connected to an inlet header and an outlet header. The present invention discloses a support for a serpentine tube arrangement and a method of construction for a non-contact heat exchanger.
