The novel described wing door mechanism's revolution action of basis as depicted in figs. 1 and 2 (periodic motion) may further comprise the steps:
Step 1, motor-driven crank move in a circle (mechanism omits) make wing door swing arm 4 and big wing door 5 rotations;
Step 2, wing door swing arm 4 and big wing door 5 are one, around 10 rotations of base for supporting axle, screw out the α degree clockwise from reset condition;
Step 3, since movable sprocket 3 the axle be contained in the wing door swing arm 4 by bearing, it is motionless to decide sprocket wheel 1, when big wing door 5 clockwise back-out α spend, under the effect of chain 2, movable sprocket 3 is rotated counterclockwise the α degree with respect to wing door swing arm 4 and big wing door 5, is installed in 3 last first gear structures 7 of movable sprocket and also is rotated counterclockwise the α degree thereupon;
Step 4, since winglet door pivot 8 be fixed on the big wing door 5, when big wing door 5 screws out, except winglet door 6 with big wing door 5 around base revolution, second gear structure 9 is first gear structure, 7 rotations on the moving sprocket wheel 3 also, make winglet door 6 from the big wing door 5 inner β degree that screw out clockwise;
Step 5, the crank on described motor push away big wing door 5 and are rotated clockwise to maximum value, continue the pulling force that the big wing door 5 of rotation will be subjected to crank, and big wing door 5 is reclaimed, and drive winglet door 6 and get back to reset condition together, finish one-period.By the operation angle of control motor and crank, realize whole back-outs of big wing door 5 and winglet door 6 or get back to reset condition.
The utility model is raised back its planet tooth transmission principle of recycling by design rocking arm chain-wheel mechanism with planetary gears and has been designed a kind of gate inhibition's wing wing centre section door mechanism that more is applicable to wide-pass, this method makes machine unit take width less, and wing wing centre section door has obtained to cover wideer gate inhibition's passage, be worth so gate inhibition's wing wing centre section door mechanism of the utility model design has higher implementation, be well suited for the mechanism of wide-pass gate inhibition demand.
