According to the adjustment mechanism, the ventilating window moving gap can be adjusted by increasing and reducing the quantity of the gaskets of the upper adjustment mechanism and the lower adjustment mechanism; the gaps among the window body, an upper window frame and a lower window frame can be further adjusted by increasing and reducing the quantity of the gaskets of the lower adjustment mechanism; and the idler wheel components are rotated, and the eccentric degree of the splines are changed, so that the adjustment of the jump, the opening and the closing force and the air impermeability of the window body can be realized, the workload can be reduced, and the labor and the time can be saved.
Description
Technical field
The present invention relates to the airplane design field, specifically a kind of regulating mechanism of aircraft ventilation window.
Background technology
Ventipane is that aircraft is in stopped status, after the aircrew enters driving compartment, provides cabin ventilation, exchanges the passage that reaches more wide visual field with ground service.Existing ventipane generally is comprised of slide rail and ventilating window body two parts, and slide rail is installed in ventilating window body between the slide rail after finish the location by tool locating.Movement clearance is bad if ventipane exists, forms jump and the problem such as the gap is undesirable, open and close power is undesirable or air-tightness is bad, will spend a large amount of manpowers and time to go to adjust.In order to address the above problem, will design a kind of mechanism that can after slide rail is connected with fuselage, regulate movement clearance, forms jump and gap, open and close power and the air-tightness of ventipane.
Following several design plan is generally arranged:
The joint that slide rail is connected with fuselage reserves the benefit stock left for machining, and is bad when movement clearance occurring, and forms jump and gap are undesirable, during the problem such as the undesirable or air-tightness of open and close power is bad, it filed repair or cushioning.
The joint that is connected with fuselage at slide rail increases slotted hole, is connected adjustment with fuselage with slotted hole first during the location, uses round orifices orientation after the gap of moving, forms jump and gap, open and close power and air-tightness adjustment are suitable again.
Movement clearance, forms jump and gap, open and close power and air-tightness for the aircraft ventilation window are regulated problem, consider that regulating mechanism is as far as possible simple and reliable.And above-mentioned several design plan, although feasible, need expend a large amount of manpowers and time, operation easier is large and unreliable.So designing simple and reliable again easy to operate ventipane movement clearance, forms jump and gap, open and close power and the bubble-tight regulating mechanism of a cover is one of work of can not ignore in the airplane design work.
Summary of the invention
The movement clearance that exists in the prior art is bad in order to overcome, forms jump and the deficiency that problem is inconvenient to regulate such as the gap is undesirable, open and close power is undesirable or air-tightness is bad, the present invention proposes a kind of regulating mechanism of aircraft ventilation window.
The present invention includes adjusted mechanism, front lower regulating mechanism and rear lower regulating mechanism.Wherein, adjusted mechanism is positioned at the upper end of ventilating window body, and is installed on the upper slide rail by the upper roller assembly.Front lower regulating mechanism and rear lower regulating mechanism lay respectively at the both sides, lower end of ventilating window body, and are installed on the glidepath by front lower roll wheel assembly and rear bottom roller assembly respectively.Described adjusted mechanism, front lower regulating mechanism and rear lower regulating mechanism include rocking arm, bolt and roll wheel assembly.Wherein:
Upper roller assembly in the adjusted mechanism comprises upper roller rotating shaft, roller and adjusting disk.The roller positioning table that radially protrudes is arranged at the middle part of upper roller rotating shaft.One side of described roller positioning table is the installation shaft of roller, and opposite side is the male splined shaft that cooperates with the internal splined hole at upper rocker arm center.The side-play amount that 1mm is arranged between the installation shaft of described roller and the line of centers of described male splined shaft.
Front lower roll wheel assembly in the front lower regulating mechanism comprises front lower roller wheel shaft, roller and adjusting disk.One end of front lower roller wheel shaft is the installation shaft of roller, and the other end of front lower roller wheel shaft is male splined shaft.The mounting groove that adjusting disk is arranged between the installation shaft of described roller and male splined shaft.Male splined shaft on the described front lower roller wheel shaft cooperates with internal splined hole on being positioned at front lower shake-changing arm.The offset that 1mm is arranged between the line of centers of described front lower rolling wheel installing shaft and the line of centers of male splined shaft.
Rear bottom roller assembly in the rear lower regulating mechanism comprises rear bottom roller rotating shaft, roller and adjusting disk.One end of rear bottom roller rotating shaft is the installation shaft of roller, and the other end of rear bottom roller rotating shaft is male splined shaft.The mounting groove that adjusting disk is arranged between the installation shaft of described roller and male splined shaft.Male splined shaft in the described rear bottom roller rotating shaft cooperates with the internal splined hole on being positioned at rear lower shake-changing arm.The offset that 1mm is arranged between the line of centers of described rolling wheel installing shaft and the line of centers of male splined shaft.
There is screw hole at the center of described each male splined shaft end face.Behind the internal splined hole on this male splined shaft is packed rocking arm into, by fix screw this male splined shaft is tightened up.
The Parameter of spline of the male splined shaft in described upper roller rotating shaft, rear bottom roller rotating shaft and the front lower roller wheel shaft is all identical.
In the window frame of the ventilating window body that each rocking arm inserted link place is installed, be fixed with boss.
During use, unload fix screw, take off roll wheel assembly, the adjusting disk quantity by increase and decrease up-down adjustment mechanism can realize the adjustment to the ventipane movement clearance; The adjusting disk quantity of increase and decrease lower regulating mechanism can also be adjusted simultaneously forms and window frame gap up and down; By the swing roller assembly, change the eccentric degree of spline, can realize forms jump, open and close power and bubble-tight adjusting.
The invention has the advantages that when ventipane occurs that movement clearance is bad, when forms jump and the problem such as the gap is undesirable, open and close power is undesirable or air-tightness is bad, can carry out simple and reliable adjusting by the relative position in eccentric spline and rocking arm upper spline hole on increase and decrease adjusting disk quantity or the change roller wheel shaft, greatly reduce work capacity, saved manpower and time.
