Lubricating oil is supplied to the rubbing surface of part by atomizer, is lubricated and cools down.Fuel pump provides source for aeroengine combustor buring room
The continuous fuel oil in source, it is the power resources of engine.An existing aero-engine is, it is necessary to design one kind by one-level fuel feeding, two-stage
The three-level oil pump of oil return composition, the use of engine is met with this；And a kind of small fuel oil pump is needed to be carried to combustion chamber
For fuel oil.Traditional design oil pump and fuel pump are individual components, are driven respectively by two transmission systems, in aero-engine
Upper to take up space greatly, transmission efficiency is low, in light weight, maintenance difficult.
The content of the invention
It is an object of the invention to provide a kind of lubricating oil and the feedway of fuel oil, solves to take present in original structure
The problems such as space is big, weight is big, inconvenient maintenance.
Slided the technical scheme is that the feedway of lubricating oil and fuel oil includes device case, lubricating oil oil feed pump, one-level
Oily scavenge oil pump, two level lubricating oil scavenge oil pump, fuel pump, input gear, driven gear, input gear engages with driven gear, driven
Be fixedly connected with little gear on gear, described little gear respectively with the driving gear of lubricating oil oil feed pump and the master of one-level lubricating oil scavenge oil pump
Moving gear engages, and the driving gear of the driving gear of described one-level lubricating oil scavenge oil pump also with two level lubricating oil scavenge oil pump engage, cunning
The driving gear of oily oil feed pump engages with the driving gear of fuel pump, described lubricating oil oil feed pump, one-level lubricating oil scavenge oil pump, two level
Lubricating oil scavenge oil pump and fuel pump installation on the device housing, and are each respectively arranged with oiler and oil-out leads to outside housing
Portion.
The shell body and device case of described one-level lubricating oil scavenge oil pump, two level lubricating oil scavenge oil pump and lubricating oil oil feed pump are one
Body, and the oiler and oil-out for leading to outside are each provided with the device housing.
Described fuel pump is bolted on device case.
Described little gear and the transmission of lubricating oil oil feed pump, one-level lubricating oil scavenge oil pump, two level lubricating oil scavenge oil pump, fuel pump are closed
System is not limited to described mode.
Power is only delivered in pump by the present invention by an input gear so that fuel feeding level, two-stage oil return level, fuel oil level
Oil pump gear obtain different gearratio, allow oil pump gear and the fuel pump normal work under preferable rotating speed.
Gear transmission structure of the present invention is simple, transmission efficiency, and after oil pump is combined with fuel pump, can effectively by
Combustion, lubricating oil are transported to part needed for engine, save space, alleviate weight, while easy to disassemble and maintenance.
