Abstract
The utility model belongs to the field of aircraft structure designing, specially relating to a hatch synchronous mechanism used by aircraft doors. The utility model adopts chains combined with gears and sprockets, realizing synchronic drive and connecting the two independent drive mechanisms with a long distance, occupying less space and having reliable function. However, the manufacture deviation imposes little influence on the chain-driven hatch synchronous mechanism,and is convenient to assemble and adjust, easy to maintain and use.
Description
Technical field
The utility model belongs to the aeroplane structure design field, particularly relates to a kind of hatch door synchronized movement mechanism that is used for aircraft door.
Background technology
Hang hatch door on the aircraft in the high density of the dark chamber of large span and be 2 fans respectively by the opposite opened hatch door of fluid motor-driven independently, every fan hatch door has the major axis of a transfer drive torque, and two major axis apart reach more than the 2m.Hatch door needs the genlocing that is synchronized with the movement in the open and close process.The rotating disk rod-pulling type hatch door synchronized movement mechanism of conventionally form is because pull bar is long, and pressurized stability is bad, and the rotating disk cable type then takes up room too greatly, all is not suitable for adopting.
Summary of the invention
The purpose of this utility model: a kind of hatch door synchronized movement mechanism is provided, can realizes having the opposite opened hatch door folding and unfolding synchronized movement of large span major axis, engineering is used reliable.
The technical solution of the utility model: a kind of hatch door synchronized movement mechanism, comprise first gear, second gear, first sprocket wheel, second sprocket wheel, the 3rd sprocket wheel, the 4th sprocket wheel, first chain and second chain, described first gear and second gear are meshing with each other, described first sprocket wheel and first gear are fixed on the same axle, second sprocket wheel and second gear are fixed on the same axle, the 3rd sprocket wheel is fixed on the left-hand axis of hatch door, the 4th sprocket wheel is fixed on the right-hand axis of hatch door, and described first chain links together first sprocket wheel and the 3rd sprocket wheel, second chain links together second sprocket wheel and the 4th sprocket wheel.
Advantage of the present utility model: the utility model utilizes chain drive that two mechanisms at a distance of the big drive of length are linked together, and space hold is little, reliable in function.And chain transmission type hatch door synchronized movement mechanism manufacture deviation is smaller to the realization of body function influence, assembling, adjusts all more conveniently, safeguards also easylier, and practicality is very strong.
Description of drawings:
Fig. 1 is the structural representation of this hatch door synchronized movement mechanism;
Fig. 2 is the scheme of installation of this hatch door synchronized movement mechanism;
Wherein, 1 first gear, 2 second gears, 3 first sprocket wheels, 4 second sprocket wheels, 5 the 3rd sprocket wheels, 6 the 4th sprocket wheels, 7 first chains, 8 second chains,
The specific embodiment: the technical program is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of hatch door synchronized movement mechanism, comprise first gear 1, second gear 2, first sprocket wheel 3, second sprocket wheel 4, the 3rd sprocket wheel 5, the 4th sprocket wheel 6, first chain 7 and second chain 8, described first gear 1 and second gear 2 are meshing with each other, described first sprocket wheel 3 and first gear 1 are fixed on the same axle, second sprocket wheel 4 and second gear 2 are fixed on the same axle, the 3rd sprocket wheel 5 is fixed on the left-hand axis 11 of hatch door, the 4th sprocket wheel 6 is fixed on the right-hand axis 12 of hatch door, and described first chain 7 links together first sprocket wheel 3 and the 3rd sprocket wheel 5, second chain 8 links together second sprocket wheel 4 and the 4th sprocket wheel 6.
As shown in Figure 2, be example with certain aircraft door, this aircraft door adopts a pair of large scale hatch door of splitting, 7.5 meters of hatch door length, 1.2 meters of width.Every fan hatch door is by the fluid motor-driven that is installed in hatch door driving shaft two ends, and two fan hatch doors are locked at shared respectively two close stances in frame lower central position, front and back end, cabin, and the motion of two fan hatch doors requires synchronously.Arrange a cover hatch door synchronized movement mechanism at frame place, front and back end, cabin respectively, guarantee the synchronized movement of two fan hatch doors.Drive the moment of torsion and the motion of the hydraulic motor output of two fan hatch door motions, associate, guaranteed synchronized movement through synchronism mechanism.Evidence, chain transmission type hatch door synchronized movement mechanism can realize desired synchronizing function.
