A tree-branch type multi-point lubricating oil injection supply structure

Abstract

The invention relates to a crotch-type multi-point slide oil injecting and supplying structure. The structure is arranged in a lubrication chamber of various rotating mechanical devices in space, andis suitable for cooling and heat dissipation of high-speed friction parts such as bearings and gears for small turbojet engines, gas turbines and other mechanical industries. The crotch-shaped slide oil supplying structure is utilized, thereby avoiding the problem of spatial interference of a slide oil injecting oil passage at a spatial position in multi-point injection slide oil when an internalor external pipeline is adopted for slide oil transportation, and also avoiding the problem of larger welding or machinery processing difficulty caused by adopting the complex internal or external oilpassage in the traditional structural design, the number of parts in a slide oil injecting and supplying structure is reduced, the structural complexity is not brought, the assemblability and maintainability are good, and the application potential is great.

Description

technical field [0001] The invention relates to a lubricating oil injection supply structure, in particular to a tree-branch type multi-point lubricating oil injection supply structure used in gas turbines, aero-engines and other machinery industries. Background technique [0002] The structural design of light lubricating oil injection suitable for small gas turbines, aero-engines and other mechanical industries is an engineering problem of great practical significance in the fields of gas turbines, aero-engines and other mechanical industries. [0003] In the structural design of lubricating oil supply for cooling in gas turbines, aero-engines and other mechanical industries, built-in or external pipelines are often used to realize the transportation of lubricating oil, and the final lubricating oil is realized by machining precision oil supply nozzles on the structural parts. Oil is sprayed precisely. Based on this structural design idea, for the structural design requir...
