redundant electromechanical actuator

Abstract

The invention discloses a redundant electromechanical actuator, which includes an actuator body, the actuator body includes two first motors, and a planetary reducer and a second motor are respectively fixedly installed on the output shafts of the two first motors. One gear, and the same idler gear meshes between the first gear and the planetary reducer, electromagnetic brakes are fixedly installed on the tops of the two first motors, and the same mounting plate is arranged above the two first motors, and A rectangular frame plate is fixedly installed on the bottom of the mounting plate, and the two first motors are located in the rectangular frame plate, and the sides away from each other of the two first motors are in contact with arc-shaped push plates. The present invention is reasonable in design, easy to operate, convenient to adjust the distance between the two first motors, to adjust the degree of engagement between the first gear and the planetary reducer and the idler gear, and the setting of the first ball and the second ball can effectively reduce the The frictional force generated by the movement of the connecting seat and the screw is convenient to use and meets the needs of use.

Description

technical field [0001] The invention relates to the technical field of electromechanical actuators, in particular to a redundant electromechanical actuator. Background technique [0002] There are many styles of redundant electromechanical actuators. Double redundant electromechanical actuators are commonly used in redundant electromechanical actuators. Dual redundant electromechanical actuators are widely used in UAV control systems to improve Reliability of UAV missions; currently, dual-redundancy electromechanical actuators include: first motor, second motor, electromagnetic brake, first motor gear, second motor gear, planetary reducer, idler, ball Lead screw pair and linear potentiometer, the first motor and the second motor, electromagnetic brakes are installed at the tails of the first motor and the second motor for motor braking, and the output shafts of the first motor and the second motor The first motor gear and the second motor gear are respectively installed at ...

AI Technical Summary

Problems solved by technology

[0003] The existing double-redundancy electromechanical actuators still have certain deficiencies. The distance between the first motor and the second motor is not convenient to adjust according to actual needs, so that the second gear, the planetary reducer and the idler gear cannot be adjusted. The degree of meshing, the second gear and the planetary reducer are prone to separation from the idler after a long period of use, resulting in the phenomenon of non-engagement, resulting in the loss of effectiveness of the planetary reducer, which brings great inconvenience to use and cannot meet the needs of use , so we propose a redundant electromechanical actuator to solve the above problems
