Description
Technical field
The present invention relates to aeroengine lubrication system, particularly a kind of bits end advertiser structure of integrated filter screen.
Background technique
The iron filings in lubricating oil oil circuit collected by the bits end advertiser of the integrated filter screen that aeroengine lubrication system uses, when last advertiser the two poles of the earth are considered in iron filings conducting to be worth doing, alarm signal can be sent online, need on ground thus inspection time dismantle integrated filter screen bits end advertiser, be separated the last advertiser of bits and filter screen, cleaning filter screen and the last advertiser magnetic head of bits, then assemble back previous condition, by analyzing iron filings with special instrument thus differentiating each parts depreciation situation in bearing bore.
That considers last advertiser and filter screen to be worth doing is designed with integrated two kinds of independent sum.The installation and removal of absolute construction need separate operation, complex operation.By the last advertiser of bits from quick-release external casing, first cannot twist nail, need special tool, by the last advertiser of bits and filter screen quick-release, cannot need twist screw thread simultaneously; Carry out flow path direction for the last advertiser of vertical bits, screen port is not accurately located relative to the last advertiser of bits; Consider the integrated filter screen of last advertiser to be worth doing when together dismantling, metal filings can spill from filter screen bottom; During mounting or dismounting, likely socket is held in misoperation, causes socket to pollute and even loosen distortion after multi-pass operation.Said structure reduces engine reliability and maintainability all to a certain extent.
Summary of the invention
The object of the invention is the integral disassembly, assembly time of considering last advertiser in order to shorten integrated filter screen to be worth doing, also shorten the time of the last advertiser of bits and filter screen dismounting simultaneously, guarantee the accurate location of considering last advertiser and filter screen to be worth doing, and increasing the last advertiser of bits and filter screen trackability, spy provides a kind of bits end advertiser structure of integrated filter screen.
The invention provides a kind of bits end advertiser structure of integrated filter screen, it is characterized in that: the bits end advertiser structure of described integrated filter screen, comprises the last advertiser of bits, loose pin, little filter core, valve, pump case, locating stud, the first seal ring, the second seal ring;
First seal ring is arranged on the housing of loose pin outside, and inside is lubricating cavity, and outside is air cavity, guarantees sealing lubricating-oil chamber; Second seal ring is arranged on loose pin outside, is positioned between electric conductor and housing, guarantees inner oil-proof;
Consider last advertiser outside to be worth doing and be provided with annular spill handle, spill width is greater than socket width, and spill length is 10 ~ 15 centimetres, and handle height slightly exceeds outlet height, and annular inner diameter is greater than socket fitting seat, is convenient to handling, and saves space;
Filter screen is with frame supported, and filter screen point is welded in lower portion, prevents filter screen by lubricating oil punching distortion; Filter screen is just flowing to lubricating oil opening, and opening and pin-and-hole circumference are accurately located, and guarantee that assembling rear lubricating oil flows to opening; Pin-and-hole and Step Shaft, to accurately locating filter screen, are guaranteed self-styled valve assembling hourglass oil outlet, are sealed hydraulic fluid port during dismounting; Step is Spielpassung with the last advertiser of bits, ensures the trackability of filter screen and the last advertiser of bits;
Filter screen is arranged on the last advertiser of bits by loose pin, and the bits end advertiser of integrated filter screen is assemblied in pump case, and locating stud is screwed in the spin slot of pump case; Little filter core and valve are arranged on pump case inside; Consider last advertiser the two poles of the earth to be worth doing to be positioned at bottom the last advertiser of bits.
Described loose pin is withstood by spring, and spring seat is the plug of considering last advertiser to be worth doing.
Described bits end advertiser is with the handle being convenient to one-handed operation.
Advantage of the present invention:
With loose pin, the bits end advertiser structure of integrated filter screen of the present invention, ensures that integrated, the axial and circumferential of the last advertiser of bits and filter screen are accurately located, tear open and filled, simplifies housekeeping operation process; Meet the operating handle of ergonomics, achieve that volume is little, the maintenance space that do not affect bits last advertiser socket etc., the function that is suitable for one-handed operation and the last advertiser socket of protection bits.
Safeguard and do not need special tool, maintenance time only needs 1 minute, and comparatively screw thread is linked with the structure shortening time 90%.Active service motor can be directly applied to, in the mechanical system design MSD of R&D motives, reduce mechanical system weight, reduce the design of exterior line and erection support, improve reliability and the maintainability of motor.
