Problems solved by technology

However, the original CFMI engine manufacturer did not provide such a tool in the manual, and there is no ready-made oil seal car on the market to meet the requirements
In the past, the method of pouring anti-rust oil directly into the accessory gearbox and then rotating the accessory gearbox 360 degrees to seal the oil was used. This method not only wastes anti-rust oil, but also cannot fully lubricate all parts in the gearbox. It does not meet the standard requirements of the manual

Embodiment 1

[0042] A method for oil sealing of an engine accessory gearbox, using the above-mentioned device for oil sealing, comprising the following steps:

[0043] (1) Prepare oil seal oil;

[0044] Take antirust oil and engine lubricating oil respectively and mix, wherein the weight percent content of antirust oil is 5%, and the weight percent of engine lubricating oil is 95%.

[0045] (2) Connect the engine accessory gearbox and drive unit:

[0046]The output shaft of the air motor 5 is connected to the input shaft of the engine accessory gearbox, and the air intake end of the air motor 5 is connected to a 10bar air source. Install the anti-leakage plugging cover at the installation attachment of the engine accessory gear box, and ensure that the air pressure shut-off valve 7 and the air pressure regulating valve 8 are in the closed position.

[0047] (3) Connect the engine accessory gearbox and oil supply unit:

[0048] The oil outlet of the oil filtering device 3 of the oil supp...

Embodiment 2

[0051] The difference from the first embodiment is that the oil supply condition of the oil-sealed pump 2 in step (4) is that the flow rate is 8.0 L / min, and the outlet pressure is 0.4 MPa.

Embodiment 3

[0053] The difference from Embodiment 1 is that the oil supply condition of the oil-sealed pump 2 in step (4) is that the flow rate is 10.0 L / min, and the outlet pressure is 0.8 MPa.

Abstract

The invention discloses an engine accessory gearbox oil-sealing method. The method includes the steps of 1, preparing sealing oil; 2, connecting an input shaft of an engine accessory gearbox to an output shaft of a drive device and driving the engine accessory gearbox by the drive device; 3, connecting an outflow end of an oil filter to an oil inlet of the engine accessory gearbox, and supplying oil to the engine accessory gearbox during oil-sealing; 4, adding the sealing oil into an oil tank, starting the drive device and an oil-sealing pump to start oil-sealing, and completing oil sealing of the engine accessory gearbox after 4-8 minutes. An oil supply device is mainly formed by connecting the oil tank, a sealing oil check valve, the oil-sealing pump and the oil filter in order. The method has the advantages that the engine accessory gearbox can be oil-sealed conveniently, oil is saved, an oil seal can meet the requirements of a manual, and parts in the engine accessory gearbox are never damaged.

Description

Technical field [0001] The invention involves a method of oil seal, especially the oil sealing method of an engine attachment gear box. Background technique [0002] The CFM56 series engine accessories gear box is a transmission device between the engine high -voltage rotor N2 and the accessories. It consists of a series of gear sets and bearing, with a speed from 3000rpm to 20000rpm.Therefore, when the attachment gear box enters the large -scale workshop and needs to stay for about two months in the large repair plant, in order to prevent high -speed running gears and bearing corrosion, the oil seal of the gear box is particularly important.However, the CFMI engine manufacturers did not provide such tools in the manual, and there were no ready -made oil seal vehicles in the market to meet the requirements.In the past, rust -proof oil was used directly into the attachment gear box, and then the 360 -degree method of rotating the attachment gear box was used to seal the oil seal. ...
