Abstract
The invention relates to a feeding device for slide oil and fuel oil. An input gear and a driven gear are engaged; a pinion is fixedly connected to the driven gear; the pinion is respectively engaged with a driving gear of a slide oil supply pump and a driving gear of a primary slide oil return pump; the driving gear of the primary slide oil return pump is also engaged with a driving gear of a secondary slide oil return pump; the driving gear of the slide oil supply pump is engaged with a driving gear of a fuel oil pump; and the slide oil supply pump, the primary slide oil return pump, the secondary slide oil return pump and the fuel oil pump are arranged on a device housing and are respectively provided with oil inlets and oil outlets, wherein the oil inlets and the oil outlets are communicated with the outside of the housing. According to the invention, power is transmitted into the pump by using only one input gear, so that the structure is simple and the transmission efficiency is high; in addition, after the slide oil pump and the fuel oil pump are combined, the fuel oil and the slide oil can be effectively conveyed to the required part of an engine, so that the space is saved, the weight is reduced, and meanwhile, the feeding device is convenient to disassemble and repair.
Description
Technical field
The present invention relates to the supplier of a kind of lubricating oil and fuel oil.
Background technique
Lubricating oil pump is for the oil system of aeroengine provides power, and fluid is flowed according to certain flow and pressure, by oil nozzle to the rubbing surface of part for lubricating oil, be lubricated and cool off.Fuel pump is the power resources of motor for the aeroengine combustor buring chamber provides endlessly fuel oil.An existing aeroengine needs a kind of three grades of lubricating oil pumps that are comprised of one-level fuel feeding, two-stage oil return of design, satisfies the use of motor with this; And need a kind of small fuel oil pump to provide fuel oil to the firing chamber.Traditional design lubricating oil pump and fuel pump all are individual components, are driven by two transmission systems respectively, take up space on aeroengine large, and transmission efficiency is low, and is lightweight, maintenance difficult.
Summary of the invention
The supplier that the purpose of this invention is to provide a kind of lubricating oil and fuel oil solves large, the problems such as weight is large, inconvenient maintenance that take up room that exist in original structure.
Technological scheme of the present invention is, the supplier of lubricating oil and fuel oil comprises device case, the lubricating oil oil feed pump, one-level lubricating oil dump pump, secondary lubricating oil dump pump, fuel pump, input gear, driven gear, input gear and driven gear engagement, be fixedly connected with small gear on the driven gear, described small gear meshes with the driving gear of lubricating oil oil feed pump and the driving gear of one-level lubricating oil dump pump respectively, the driving gear of described one-level lubricating oil dump pump also with the engagement of the driving gear of secondary lubricating oil dump pump, the driving gear of lubricating oil oil feed pump and the engagement of the driving gear of fuel pump, described lubricating oil oil feed pump, one-level lubricating oil dump pump, secondary lubricating oil dump pump and fuel pump are installed on the device case, and are respectively arranged with oiler separately and oil outlet leads to outside.
Frame and the device case of described one-level lubricating oil oil feed pump, secondary lubricating oil oil feed pump and lubricating oil dump pump are integrated, and are provided with separately oiler and the oil outlet that leads to the outside on device case.
Described fuel pump is bolted on the device case.
The drive connection of described small gear and lubricating oil oil feed pump, one-level lubricating oil dump pump, secondary lubricating oil dump pump, fuel pump is not limited to described mode.
The present invention only is delivered to power in the pump by an input gear, so that the oil pump gear of fuel feeding level, two-stage oil return level, fuel oil level obtains different velocity ratios, allows oil pump gear and fuel pump work under desirable rotating speed.
Gear transmission structure of the present invention is simple, and transmission efficiency is high, and with lubricating oil pump after fuel pump is combined, can be effectively combustion, lubricating oil be transported to the required part of motor, saved the space, alleviated weight, be convenient to simultaneously dismounting and maintenance.
