Abstract

The invention belongs to the technical field of electromechanical servo, and particularly relates to a horizontal stabilizer electromechanical actuator adopting double-channel transmission anti-backlash control. Compared with the traditional electromechanical actuator structure layout and functional form, the horizontal stabilizer electromechanical actuator adopting double-channel transmission anti-backlash control provided by the invention has higher safety and reliability, can ensure the position locking and backlash elimination of the stabilizer; meanwhile, a nested roller screw pair greatly improves the integration degree of an actuating device, has high thrust and high power, can be popularized and applied to horizontal stabilizers of existing civil aircrafts, military transporters and heaven and earth reciprocating aircrafts, and can also be applied to the field of industrial machine tool or cabin door actuating.

Description

technical field [0001] The invention belongs to the technical field of electromechanical servo, and in particular relates to an electromechanical actuator for double-channel transmission anti-backlash control of a horizontal stabilizer. Background technique [0002] The function of the horizontal stabilizer is to make the aircraft have proper static stability in the pitch direction, and keep the aircraft in a horizontal flight attitude after being disturbed. The horizontal stabilizer actuator is an important part of the horizontal trim. The reliability and safety of the actuator and even the aircraft require the actuator to have the functions of high reliability, reverse self-locking, and anti-backlash preload. [0003] The existing horizontal stabilizer actuator technical scheme is based on the electromechanical actuator driven by ball screws, arranged through parallel gears, and driven by dual motor power sources. The entire actuator is large in size, heavy in weight, low ...
