Description

Technical Field

[0001] The utility model relates to the technical field of intermediate casing lubricating oil nozzle testing, in particular to a filtering device which is convenient for removing internal parts. Background Art

[0002] The intermediate casing is located in the middle of the aircraft engine, between the fan casing and the high-pressure compressor. It is the connection and transition channel of the engine. It is the heart of the engine and the aircraft hoisting, and is the most important load-bearing structure of the engine. The thrust of the engine is mainly transmitted to the aircraft through the intermediate casing, the main thrust mounting section and the auxiliary thrust mounting section. Among them, the intermediate casing bears the overall weight of the engine, vibration, maneuvering overload, and complex forces of four degrees of freedom. Therefore, the intermediate casing needs to be closely integrated with the high-pressure compressor, low-pressure compressor, fulcrum bearing seat and other components, and the research and development requirements are very high.

[0003] The oil nozzle is an essential part in the transmission and lubrication system of an aircraft engine. It is used to provide lubricating oil to bearings, gears and dynamic involute splines to achieve the design functions of lubrication and cooling.

[0004] Most of the existing nozzle test filtering devices are of one-piece design. After use, there are a lot of impurities and filtered dust inside the device. The existing device is very inconvenient to clean later. It is necessary to disassemble the device itself from the working position and also to disassemble the device casing as a whole. The use is cumbersome, which leads to a reduction in the normal use time of the device and a reduction in work efficiency. Utility Model Content
