Abstract
The invention discloses a sealing structure for a propeller root end surface opening of a propeller blade. The sealing structure comprises a metal plug cap, a sealing pad and pins, wherein screw threads are arranged on the periphery of the plug cap, a sealing pad groove is formed in an extending-out projected position of the plug cap, the sealing pad is arranged in the sealing pad groove of the plug cap, the plug cap is fixedly arranged on the propeller root end surface opening of the propeller blade through screw threads, the sealing pad is tightly pressed, one or more than one through hole is formed in the plug cap and the sealing pad, a blind hole which has the same diameter and is communicated with the through hole is formed in the same position of the propeller root end surface opening of the propeller blade, and the pins are in interference assembly in the through hole and the blind hole. The sealing structure has the advantages that the assembly reliability is high, during the assembling, the sealing structure of the sealing pad is not damaged, the sealing effect is good, and oil liquid is prevented from entering the propeller blade; therefore the influence on the moment balance of the propeller blade is avoided, the influence on the dynamic balance of the whole structure is avoided, the occurrence of a caused structure vibration phenomenon is avoided, and the service life of the propeller blade is prolonged.
Description
Technical field
The present invention relates to a kind of sealing configuration of blade blade root end face opening.
Background technique
Blade blade root is metallic material, its end face has an opening, and the sealing configuration of existing blade blade root end face opening is the blanking cover sealing adopting nylon material to make, and blanking cover side is fluted, have a circle " O " type rubber seal in groove, blanking cover interference crimping is fixed on blade blade root end face opening.The radial seal of " O " RunddichtringO, blade root blanking cover are nylon material, machining accuracy should not be ensured, and it is yielding after processing, when assembling blanking cover simultaneously, easy destruction " O " RunddichtringO edge, can not be found again, once " O " RunddichtringO edge is destroyed, under propeller works state, easily cause blade from the oil-feed of root opening, once fluid enters blade inside, blade equalising torque can be affected, thus affect the dynamic balancing of total, the structural vibration simultaneously caused, reduce the working life of blade.So, be badly in need of thoroughly improving sealing configuration, to meet usage requirement.
Summary of the invention
Object of the present invention solves the above-mentioned problems in the prior art exactly, there is provided a kind of sealing configuration of blade blade root end face opening, sealing Standard reliability is high, does not destroy the sealing configuration of sealing gasket during assembling, good sealing effect, avoids fluid and enters blade inside.
For achieving the above object, technical solution of the present invention is: a kind of sealing configuration of blade blade root end face opening, and it comprises metal blanking cover, sealing gasket and pin; Blanking cover circumferentially have screw thread, the raised position leant out has gasket slot, and sealing gasket is placed in the gasket slot of blanking cover; Blanking cover screw thread is fixed on blade blade root end face opening, press seal pad; Blanking cover and sealing gasket have one and above through hole, and have with above-mentioned through hole same diameter and the blind hole be communicated with in the same position of blade blade root end face, pin elastic conjunction is in through hole and blind hole.
The blanking cover through hole of elastic conjunction pin described above closes up.
The present invention changes the radial seal of original blanking cover into end face seal, the rear yielding nylon blanking cover of machining accuracy is low, processing changes the high metal blanking cover of machining accuracy into, and adopt screw thread to be connected press seal pad with blade blade root, adopt the pin of elastic conjunction to prevent metal blanking cover from rotating.In a word, assembly reliability of the present invention is high, does not destroy the sealing configuration of sealing gasket, good sealing effect during assembling, avoids fluid and enters blade inside; Thus avoid and affect blade equalising torque, thus avoid the dynamic balancing affecting total, avoid the generation of the phenomenon of the structural vibration caused simultaneously, extend the working life of blade.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in Figure 1, the present embodiment comprises metal blanking cover 1, sealing gasket 2 and pin 3.Blanking cover 1 circumferentially have screw thread 5, the raised position leant out has gasket slot, and sealing gasket 2 is placed in the gasket slot of blanking cover 1.Blanking cover 1 screw thread is fixed on blade blade root 4 end face opening, press seal pad 2.Blanking cover 1 and sealing gasket 2 have the through hole of (may also be two or three etc.), and have with above-mentioned through hole same diameter and the blind hole be communicated with in the same position of blade blade root 4 end face, pin 3 elastic conjunction is in through hole and blind hole.Preferably, in the blanking cover through hole surrounding punching of elastic conjunction pin, to ensure that the blanking cover through hole of elastic conjunction pin closes up.
Above-described embodiment is only preferred and exemplary, and those skilled in the art can do equivalent technologies according to the spirit of this patent and improve, and these all covered by the protection domain of this patent.
