Patent number: 11035421Abstract: A clutch system configured to transmit torque between an input shaft and an output shaft. The clutch system may include a clutch and a lubrication supply system. The clutch may include: an input portion disposed at an end of the input shaft; an output portion disposed at an end of the output shaft; and a sliding component that slides axially between the input and output portions to engage the clutch. The lubrication supply system may include: one or more lubricant feeds for delivering a lubricant to the clutch; and one or more lubricant drains for draining the lubricant from the clutch. The one or more lubricant feeds may include one or more respective valves. The one or more valves each may be configurable between settings that vary an amount of the lubricant delivered to the clutch via the respective one of the one or more lubricant feeds.Type: GrantFiled: May 1, 2019Date of Patent: June 15, 2021Assignee: General Electric CompanyInventors: Jason Winfred Jewett, Thomas Joseph Farineau, Siddharth Navinchandra Ashar, Andrew John Lammas, Paul Richard Stukenborg, Eric Paul Knopf, Mateusz Wojciech Golebiowski, Chad Duncan Munkres, Eric Lorin Letterman

Patent number: 9435217Abstract: A seal assembly for sealing between a rotating component and a stationary component in a turbomachine. The seal assembly includes a plurality of radially inwardly projecting, axially spaced teeth extending from the stationary component, wherein at least one of the plurality of teeth has at least one axially extending hole therethrough. Axial flow of an operating fluid through the holes acts as an air-curtain to interrupt swirl flow in a seal cavity, therefore reducing steam force that could act to destabilize rotordynamics.Type: GrantFiled: October 6, 2015Date of Patent: September 6, 2016Assignee: General Electric CompanyInventors: Xiaoqing Zheng, Daniel Mark Brown, Jason Winfred Jewett, Fred Thomas Willett, Jr.

Publication number: 20120227536Abstract: A solution is provided for tuning the frequency of a rotating body. A sectioned tuning ring is mounted to a flange coupling that couples a first part and a second part of a rotating body together. The sectioned tuning ring adjusts the frequency of the rotating body. The sectioned tuning ring can be bolted on to the rotating body as it is in an operating position within the machine, thus eliminating the need to remove the rotating body from the machine.Type: ApplicationFiled: March 10, 2011Publication date: September 13, 2012Applicant: GENERAL ELECTRIC COMPANYInventors: Jason Winfred Jewett, Eloy Vincent Emeterio
