A structure of an aero-engine split centrifugal ventilator

Abstract

The invention discloses a split type centrifugal ventilator structure of an aero-engine, which relates to the technical field of aero-engines, and comprises a gear shaft, one end of which is provided with a gas channel, and the separated gas after oil and gas separation is discharged out of the gear box; an oil and gas separator, an oil and gas separation The device is composed of an inner ring, an outer ring and a number of supporting walls between the two. The inner ring is provided with a number of first supporting parts and a number of second supporting parts. One end of the inner ring is provided with a number of claw grooves for the inner ring. Several claw grooves in the outer ring; gears with webs, used in conjunction with the oil-air separator to prevent the oil-air mixture from leaking from the oil-air separator. Through the combined design of the gear and the oil-gas separator, the present invention can effectively and stably separate the gas-liquid from the oil and gas of the gear box while transmitting power, without occupying a large installation space, reducing weight and cost, and effectively improving The integrated design level of gearbox components is improved.

Description

An aero-engine split centrifugal ventilator structure technical field The invention belongs to aero-engine technical field, specifically a kind of aero-engine split type centrifugal ventilator joint. structure. Background technique The accessory transmission gearbox is a key component of the aeroengine, and its transmission gear will generate a large amount of heat during operation. It is necessary to continuously use lubricating oil for circulating heat dissipation and lubrication. During the lubricating oil circulating and lubricating process, the A large amount of gas-liquid mixture such as oil mist and oil and gas will be generated in the external part, which will cause a certain amount of heat dissipation of the lubricating oil and internal pressure of the gearbox. Therefore, it is necessary to use corresponding devices to separate the oil and gas in the gearbox; the traditional solution is to A separate installation interface platform is designed on the trans...
