Abstract
The patent application of the invention relates to an improved technology for realizing the correct assembly of a wheel hub and a wheel shaft of an airplane. In the assembly structure, the plug tool is easy to reversely mount, so that great accident potential is caused, and in order to solve the technical problem, the invention provides a technical scheme which takes the annular boss arranged on the ring sleeve of the plug tool as the main technical characteristic, so that after the plug tool is reversely mounted, related parts cannot be normally mounted in place, the potential safety hazard of the mounting structure is avoided, and the flight safety of an airplane is ensured.
Description
Technical field
What the present invention relates to is the improvement technology of the mounting structure of airplane wheel and wheel shaft.
Background technology
The wheel shaft of airplane wheel and the assembling of wheel are to make wheel shaft and the assembling of special material wheel hub bearing, the brake gear of fixing simultaneously assembling wheel, its structure formation comprises: wheel beam warp conical shaft holds with the casing bearing and cooperates, its brake gear is by brake main body reaction plate and mounting flange, lining and gascheck press the inner end surface place in conical bearing, wherein, gascheck is one to be used for forbidding that at the wheel high-speed operation bearing lubrication grease pours into the annular arrangement accessory of braking mechanism that the structure of this accessory is: annular bottom plate is provided with to filling the protruding ring set of seal ring.In actual assembled, the as easy as rolling off a log dress of this gascheck is anti-, and also can't discover its mistake by any inspection means, can normal operation because relative each mechanism adorns under the anti-situation also at it, can therefore there be serious accident potential: in the aircraft landing, most of lubricating grease is clamp-oned the middle cavities of ring set in the conical bearing in the aircraft running, cause parts such as bearing and wheel shaft to be sticked together because of high temperature operation, cause the wheel seize, even grave accident such as tyre break, aircraft flight safety is subjected to very big threat, and national wealth suffers a loss, and personal safety can't guarantee.For many years, this fatal technological deficiency is not solved effectively.
Summary of the invention
For solving the existing fault of construction of fixed sturcture between present airplane wheel parts and the wheel shaft, particularly in actual assembled, can't find the whether anti-fault of construction of dress of gascheck effectively, the invention provides the technical scheme of a cover airplane wheel axle set mounting mechanism, the major technique content of this technical scheme is: wheel beam warp conical shaft holds with wheel hub and connects, the brake reaction plate of braking mechanism is through lining, gascheck is installed on the inner end surface of conical bearing, and the major technique characteristics of the technical program are on the gascheck ring set, one annular boss is set on the position greater than conical bearing diameter of bore.
In above-mentioned overall technical architecture, its radial dimension of the annular boss of gascheck is less than the big end radial dimension of lining.
The technical scheme of patent application of the present invention, owing on the ring set of gascheck, be provided with annular boss, it can only be installed by forward, when reverse installation wrong having occurred, because the existence of this annular boss, force its associated components can not enter normal assembling position, more can't normal operation, thereby to such an extent as in assembling the problem place of all as easy as rolling off a log discovery mounting structure after the assembling.When if anti-the dress occurring, this boss can't be inserted in the big end of bearing and realizes putting in place installation in the axial bore of gascheck, make outside the installation position of bearing and move, the wheel installation that can not put in place, gear member on the wheel hub can't be meshed with the input gear of inertial sensor, braking mechanism can't be worked, and inertial sensor does not more have should effect.So present technique not only can be prevented the reverse installation of gascheck self, also can effectively prevent the reverse installation of lining, just can avoid the generation of grave accidents such as wheel seize or tire blow-out, improved the safety performance of landing system.

The specific embodiment
The mounting structure of airplane wheel and its wheel shaft is a part comparatively crucial in the aircraft landing mechanism.Be provided with conical bearing 2 in the inner lining 7 of airplane wheel wheel hub 1, wheel shaft is cooperated with wheel hub 1 bearing, these bearing 2 the inners just its big end inboard be provided with wheel braking mechanism in being installed on, be set in brake main body reaction plate, mounting flange, lining 5 and gascheck 6 on the wheel shaft, gascheck 6 wherein is an annular arrangement accessory, its annular arrangement base plate one side is provided with ring set 4, and the periphery of ring set 4 is provided with grommet type seals.When normal mounting, the base plate of gascheck 6 presses on the large end face of conical bearing 2, lining 5 is set in ring set 4 inner chambers of gascheck 6 other parts of connection successively again, ring set 4 upper surfaces of gascheck 6 are provided with an annular boss 42, the radial dimension of this annular boss 42 is less than the internal diameter of machine hub gear member 3, greater than conical bearing 2 diameter of bores, its axial height, promptly it axially overlaps and measures less than lining 5 height dimensions, so the setting of annular boss 42 does not influence the installation of lining 5 deeply.In the present embodiment, annular boss 42 radial dimensions of gascheck 6 are less than the radial dimension of lining 5 big ends, and this structure can prevent the anti-dress mistake of lining effectively.
In the present embodiment, for guaranteeing the stable of aircraft operating weight as much as possible, the annular boss 42 of gascheck is provided with some through holes 43, also can be provided with some shrinkage pools 44 on the upper surface of ring set 4.
