Abstract

The invention discloses a transmission structure of a dual-redundancy electric mechanism. The transmission structure comprises a first motor, a first gear transmission assembly, a worm gear assembly,a rocker arm, a second motor and a second gear transmission assembly. The first motor is in transmission connection with the first gear transmission assembly, the second motor is in transmission connection with the second gear transmission assembly, the rocker arm is movably connected with the first gear transmission assembly and the second gear transmission assembly, and the first gear transmission assembly and the second gear transmission assembly are disengaged from and engaged with the worm gear assembly by swinging the rocker arm.

Description

technical field [0001] The invention belongs to the technical field of electric mechanism transmission, and in particular relates to a transmission structure of a double-redundancy electric mechanism. Background technique [0002] In the aerospace electromechanical system, the electric mechanism drives the load to rotate through the motor-driven transmission structure, and at the same time feeds back the rotation angle to the upper system. It is a key executive component and has high requirements for reliability. At present, the use of double redundant electric mechanism is an effective way to improve reliability. Most of the existing double-redundant electric mechanisms adopt the method of differential gear or fault-tolerant motor. [0003] The differential can effectively avoid force disputes when working at the same time, but it brings an increase in the moment of inertia, moment of inertia, and weight, and the structure is complicated. After the failure of one winding ...
