The invention discloses a dual-redundancy undercarriage cabin door electric actuating retracting and releasing device which comprises a servo motor (3) and a direct-current motor (4), the servo motor(3) and the direct-current motor (4) are provided with brakes and do not work simultaneously, and an output shaft of the servo motor (3) is meshed with a sun gear of a planetary reducer. An output shaft of the direct-current motor is meshed with outer teeth of an inner gear ring of the planetary reducer (7), the planetary reducer (7) is arranged on the output shaft (5), a planet carrier (7.3) of the planetary reducer (7) serves as an output to drive the output shaft (5) to rotate, and an output rocker arm (1) connected with an undercarriage cabin door pull rod is arranged on the output shaft (5). The servo motor and the direct-current motor are adopted as power output sources for mutual backup, and the motor brake and the planetary gear reducer are adopted as differential devices of the two motors, so that the device is suitable for use scenes with low requirements on the folding and unfolding speed of the undercarriage cabin door, short working time and large load.

    本发明公开一种双余度起落架舱门电作动收放装置,包括伺服电机(3)和直流电机(4),伺服电机(3)和直流电机(4)均带有制动器,并且不同时工作,其中所述伺服电机(3)输出轴与行星减速器的太阳轮啮合,直流电机的输出轴与行星减速器的内齿圈的外齿啮合,行星减速器(7)设置在输出轴(5)上,行星减速器(7)的行星架(7.3)作为输出,带动输出轴(5)转动,输出轴(5)上设有与起落架舱门拉杆连接的输出摇臂(1)。本发明采用伺服电机和直流电机作为互为备份的动力输出源,并采用电机制动器和行星齿轮减速器作为两个电机的差速装置,适用于起落架舱门收放速度要求不高、工作时间短、载荷大的使用场景。
