Abstract

The invention relates to a supply device for lubricating oil and fuel oil. The input gear meshes with the driven gear, and the driven gear is fixedly connected with a pinion gear. The driving gear of the oil return pump meshes, and the driving gear of the first-stage lubricating oil return pump also meshes with the driving gear of the second-stage lubricating oil return pump, and the driving gear of the lubricating oil supply pump meshes with the driving gear of the fuel pump. The lubricating oil supply pump, the primary lubricating oil return pump, the secondary lubricating oil return pump and the fuel pump are installed on the device housing, and are respectively provided with an oil inlet and an oil outlet leading to the outside of the housing. The invention only transmits power to the pump through one input gear, has simple structure and high transmission efficiency, and after combining the lubricating oil pump and the fuel pump, it can effectively transport the fuel and lubricating oil to the required parts of the engine, saving space. Reduced weight while facilitating disassembly and repair.

Description

technical field [0001] The invention relates to a supply device for lubricating oil and fuel oil. Background technique [0002] The lubricating oil pump provides power for the lubricating oil system of the aero-engine, so that the oil flows according to a certain flow and pressure, and supplies lubricating oil to the friction surface of the parts through the oil injection nozzle for lubrication and cooling. The fuel pump provides a steady flow of fuel for the combustion chamber of the aero-engine and is the power source of the engine. For an existing aero engine, a three-stage lubricating oil pump consisting of one-stage oil supply and two-stage oil return needs to be designed to meet the use of the engine; and a small fuel pump is required to provide fuel to the combustion chamber. Traditionally designed lubricating oil pump and fuel pump are independent components, driven by two transmission systems, respectively, occupying a large space on the aero-engine, low transmissi...
