Tilt Pad Journal Bearing
US Patent:
4746230, May 24, 1988
Filed:
Feb 17, 1984
Appl. No.:
6/581020
Inventors:
Richard C. Jensen - Greensburg PA
Assignee:
Elliott Turbomachinery Co., Inc. - Jeannette PA
International Classification:
F16C 1703
US Classification:
384311
Abstract:
A tilt pad bearing assembly for use in supporting a rotating shaft is disclosed. The bearing assembly includes lubricant means for effectively cooling separate individual bearing pads, and separate cooling channels for selectively cooling a portion of the bearing pad. The bearing pads each have a specific end treatment to act in combination to provide an anti-spragging effect. Additionally by selectively cooling a portion of the bearing pad, the bearing pad may have separate configurations for low speed and high speed applications such that boundary lubrication is achieved under low speed conditions and dynamic lubrication is achieved under high speed conditions.
Method Apparatus Using A Cavitating Venturi To Regulate Lubricant Flow Rates To Bearings
US Patent:
4621931, Nov 11, 1986
Filed:
Dec 19, 1983
Appl. No.:
6/562613
Inventors:
Richard C. Jensen - Greensburg PA
Assignee:
Elliott Turbomachinery Co., Inc. - Jeannette PA
International Classification:
F16C 1702, F16C 1712, F16C 3310
US Classification:
384114
Abstract:
A method and apparatus for regulating the flow of liquid lubricant to hydrostatic bearings is disclosed. A cavitating venturi is utilized to regulate the volume flow rate of liquid lubricant supplied to a bearing. The cavitating venturi acts to provide a constant volume flow rate of liquid lubricant relatively independent of system flow resistance and feed pressure to the bearing.
Erosion Probe Having Inductance Sensor For Monitoring Erosion Of A Turbomachine Component
US Patent:
4328462, May 4, 1982
Filed:
May 12, 1981
Appl. No.:
6/262853
Inventors:
Richard C. Jensen - Greensburg PA
Assignee:
Carrier Corporation - Syracuse NY
International Classification:
G01R 3312, G01B 710, G01N 1700
US Classification:
324229
Abstract:
An erosion probe for monitoring erosion of a component of a turbomachine by fluid flow therepast comprising a shell having a predetermined erosion rate proportional to the erosion rate of the component, and an electric inductance sensor encapsulated secured within the shell for generating an electric signal indicative of shell erosion.
Flexible Damped Bearing Assembly
US Patent:
4793722, Dec 27, 1988
Filed:
Aug 14, 1984
Appl. No.:
6/640893
Inventors:
Richard C. Jensen - Greensburg PA
Assignee:
Elliott Turbomachinery Co., Inc. - Jeannette PA
International Classification:
F16C 2706
US Classification:
384 99
Abstract:
A flexible damped bearing assembly for securing a rotating shaft maintained within a bearing is disclosed. An annular damper formed from a resilient material includes an axial bore for receiving the bearing and shaft. The damper is additionally slotted to define damper arms extending outwardly therefrom. Damper pads are used in conjunction with the damper arms to define pivot points about which the damper arms are displaced on the application of force to the damper. A damping fluid is provided between the slots and the exterior surface of the damper and a retainer structure such that numerous damping locations are provided. The damper arms are further defined to provide a spring force which may be tuned as required. This combination provides a compact bearing assembly capable of supporting a shaft while damping vibratory oscillations.
