The invention discloses a dual-redundancy electromechanical actuator which is composed of a base (3), a left supporting plate (4A), a right supporting plate (4B), a cover body (5), a six-phase fault-tolerant motor (1), a planetary roller lead screw assembly (2), a left end transmission assembly and a right end transmission assembly. The left end transmission assembly and the right end transmission assembly are the same in structure. The transmission assembly comprises a helical spur gear, a rotating shaft, an idle gear and an electromagnetic brake. According to the invention, the six-phase fault-tolerant motor (1) is matched with the helical gear to realize linear output of the planetary roller screw assembly (2). Through the left end transmission assembly and the right end transmission assembly which are installed at the two ends of the motor shaft (1A) respectively, the size and the weight of the electromechanical actuator are reduced under the independent transmission mode of the left end and the right end.
本发明公开了一种双余度机电作动器,其由底座(3)、左支撑板(4A)、右支撑板(4B)、罩体(5)、六相容错电机(1)、行星滚柱丝杠组件(2)、左端传动组件和右端传动组件构成;其中左端传动组件与右端传动组件的结构相同。传动组件包括有斜齿圆柱齿轮、转轴、惰轮和电磁制动器。本发明是以六相容错电机(1)与斜齿圆柱齿轮的配合,实现行星滚柱丝杠组件(2)的直线输出。通过电机轴(1A)两端分别安装的左端传动组件和右端传动组件使得左右两端独立传动方式下,减小了机电作动器的体积和重量。
