Problems solved by technology
The traditional helicopter main reduction lubricating oil system only through the mechanical temperature control valve, by feeling the temperature of the lubricating oil at the inlet of the radiator, passively adjusts the flow through the radiator to ensure that the temperature of the lubricating oil does not exceed the limit, realizes the passive adjustment of the lubricating oil temperature, and dissipates heat The cooling fan of the engine is always running at the maximum power state, and the helicopter consumes a lot of energy

Embodiment Construction
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0017] The main lubricating oil system proposed by the present invention, its principle is as follows figure 1 shown. The oil circuit of the main reduction lubricating oil system is divided into an internal pressurization circulation circuit and an external cooling circulation circuit.
[0018] Working principle of the internal pressurized circulation circuit: Two booster pumps in the small lubricating oil pool pump the cold lubricating oil at...

The invention belongs to the technical field of lubricating systems for main speed reducers of helicopters, and discloses an anti-leakage lubricating oil system. A booster pump is used for pumping lubricating oil in a lubricating oil pool to a to-be-lubricated structure to lubricate and cool the to-be-lubricated structure, and the lubricating oil after the lubricating flows into an oil collectingpool; and the oil collecting pool is connected with the lubricating oil pool through an external cooling circulation loop, the external cooling circulation loop comprises an oil return pump and a radiator, the oil return pump is used for pumping the lubricating oil to the radiator, the radiator is used for cooling the lubricating oil, and the cooled lubricating oil flows into the lubricating oil pool. When lubricating oil leakage happens to an external pipeline or a part of the main reducer, the main reducer cannot lose lubrication completely, so that dry running of the main reducer is prevented. The power of the radiator is controlled by controlling the rotating speed of a fan, and active adjustment for the temperature of the lubricating oil of the main reducer is realized through activecontrol over the flow of the lubricating oil passing through the radiator.
Description
technical field [0001] The invention belongs to the technical field of the lubrication system of the main reducer of a helicopter, and in particular relates to an anti-leakage lubricating oil system. Background technique [0002] The main reducer of a helicopter relies on the lubricating oil system to provide lubrication and cooling for its gears and bearings. The reliability of the main reducing lubricating oil system directly affects the flight safety of the helicopter. The existing typical main oil reduction systems for helicopters at home and abroad, such as AC313 helicopter and AC311 helicopter, and [Journal Papers] Li Linwei, Gao Hongxia, Yu Jianzu, Chang Li, Zuo Lihua, Zhu Hong, "Helicopter Technology" 2008 Issue 4 published In a typical main reduction lubricating oil system, the external cooling circulation circuit and the internal pressurized oil supply circuit share the lubricating oil pump. When there is an oil leakage failure in the external pipeline or component...
