METHOD AND DEVICE FOR CONTROLLING BEARING LOAD IN BEARING ASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide an orifice plate assembly 82 for a gas turbine engine 10 for assisting a bearing assembly 70 inside the gas turbine engine in prolong the effective life thereof. SOLUTION: Each orifice plate assembly is connected to an engine air supply source 74 so as to hydraulically communicate with each other and comprises a first body portion 100 and a second body portion 102. The first body portion comprises a groove part 108 and a flow opening 130. The groove part is formed in such a dimension that can receive the second body portion so that the second body portion can be slid on the first body portion. The orifice plate assembly is adjustable so that a bearing load can be adjusted after the engine stops.
