Description
Technical field
The present invention relates to undercarriage control technical field, be specially a kind of two remaining electric actuating cylinder.
Background technology
Pressurized strut is the important component part of system as the power element of landing-gear system, and pressurized strut is broken down will directly affect persons on board's life security, therefore on critical product aircraft affecting aircraft and personal security, requires to improve its reliability.But current undercarriage extension and retraction system is still traditional hydraulic way and controls, its hydraulic actuator is without back-up job passage, and hydraulic actuator volume and weight is comparatively large, can increase aircraft energy consumption.
Summary of the invention
The object of the invention is to provide a kind of structure simple two remaining electric actuating cylinder to overcome above-mentioned deficiency.
The present invention includes cylinder barrel and be located at the first motor on cylinder barrel, described first motor is provided with the first input shaft, described first input shaft is provided with gear ring, described gear ring is provided with satellite gear, described satellite gear is arranged in pinion carrier, described pinion carrier inner sleeve has leading screw, feed screw nut is provided with outside described leading screw, described feed screw nut is connected with piston by tie bolt, described piston is provided with push rod, one end of described push rod is provided with rod end bolt, described cylinder barrel is also provided with the second motor, described second motor is provided with the second input shaft, described second input shaft engages with breast wheel, described breast wheel engages with dual gear, described dual gear is connected with satellite gear.
Present invention employs two-way motor and drive each self-corresponding reducing gear respectively, the final version sharing a set of planetary wheel output mechanism, when motor or the train of gears fault clamping stagnation of product first passage, power supply is forwarded on the motor of second passage, the driven by motor second sleeve gear system work of second passage, thus drive whole product work, realize whole product function.In any case, in two motors, only have an electrical power job, greatly can improve the reliability of whole product.Simultaneously because conventional hydraulic pressurized strut load-carrying capacity is larger, its piston rod can bear the transmission of motion and load simultaneously, electric actuating cylinder drive disk assembly by contrast, as less in the parts such as leading screw and gear load-carrying capacity, therefore need to move when pressurized strut works to be separated with the transmission of load.The present invention, after product work to assigned address, is stuck in the lock slots of cylinder barrel by movable locking plate, load is transferred to cylinder barrel by leading screw and is delivered to product structure, ensures that internal motion transfer components no longer continues stressed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the B-B of Fig. 1 is to schematic diagram.
Fig. 3 be in Fig. 3 C to schematic diagram.

Detailed description of the invention
The present invention is further illustrated below in conjunction with drawings and Examples.
Embodiment: the first motor 13 that the present invention includes cylinder barrel 10 and be located on cylinder barrel 10, described first motor 13 is provided with the first input shaft 3, described first input shaft 3 is provided with gear ring 4, described gear ring 4 is provided with satellite gear 21, described satellite gear 21 is arranged in pinion carrier 20, described pinion carrier 20 inner sleeve has leading screw 9, feed screw nut 18 is provided with outside described leading screw 9, described feed screw nut 18 is connected with piston 12 by tie bolt 17, described piston 12 is provided with push rod 8, one end of described push rod 8 is provided with rod end bolt 6, described cylinder barrel 10 is also provided with the second motor 14, described second motor 14 is provided with the second input shaft 5, described second input shaft 5 engages with breast wheel 2, described breast wheel 2 engages with dual gear 1, described dual gear 1 is connected with satellite gear 21.Be provided with steel ball 15 in described piston 12, described steel ball 15 is provided with snap ring 16, is provided with locking plate 11 between described cylinder barrel 10 and steel ball 15.
Principle of work of the present invention is as follows: when the first motor 13 works, because the second motor 14 is carried electromagnetic brake locking, the second input shaft 5, breast wheel 2 and the dual gear 1 that are connected with the second motor 14 are lockable simultaneously, namely dual gear 1 is motionless as the tight pulley of planetary gear train, now the first motor 13 drives the first input shaft 3 to work, and drive the external gear on gear ring 4 to rotate, then transmit motion to pinion carrier 20 by satellite gear 21 and drive leading screw 9 to rotate.When second motor 14 works, because the first motor 13 is by the electromagnetic brake locking carried, the first input shaft 3 be connected with the first motor 13 and gear ring 4 are lockable simultaneously, namely the inner gear on gear ring 4 is motionless as the tight pulley of planetary gear train, now the second motor 14 drives the second input shaft 5 to work, and drive breast wheel 2 and dual gear 1 to rotate, then transmit motion to pinion carrier 20 by satellite gear 21 and drive leading screw 9 to rotate.
When certain motor rotating forward work, leading screw 9 is driven to rotate by reducing gear thus to drive feed screw nut 18 to rotate the tie bolt 17, piston 12, push rod 8 and the rod end bolt 6 that make it promote to be attached thereto protruding.When piston 12 moves to desired location, locking plate 11 pushes in the lock slots on cylinder barrel 10 by the steel ball 15 in piston, and piston position is locked, and the load now on push rod 8 is passed on product structure by locking plate 11 and cylinder barrel 10.When certain motor reversal works, rotated backward by gear drive leading screw 9, now steel ball 15 pressure is released and makes it fall after rise, and locking plate 11 is deviate from from lock slots, piston 12 unlocks state, thus makes leading screw 9 can drive feed screw nut 18 that piston 12 and push rod 8 are regained.When piston 12 moves to desired location, snap ring 16 pushes in the lock slots on cylinder barrel 10 by the steel ball 15 in piston, and piston 12 position is locked, and the load now on push rod 8 is passed on product structure by snap ring 16 and cylinder barrel 10.
Above-described embodiment is the present invention's preferably embodiment; but embodiments of the present invention are not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present invention and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
