Abstract

The invention provides a cycloidal-pin wheel speed reduction type electric steering engine. The cycloidal-pin wheel speed reduction type electric steering engine comprises a servo motor, a servo motorbevel gear, a shell, an eccentric shaft, a rear end cover, a first crossed roller bearing assembly, a second crossed roller bearing assembly, a first cycloidal gear support, a second cycloidal gear support, a first cycloidal gear support roller assembly, a second cycloidal gear support roller assembly, a roller pin assembly, a cycloidal gear, a flange and an axial locking part, wherein the eccentric shaft, the rear end cover, the first crossed roller bearing assembly, the second crossed roller bearing assembly, the first cycloidal gear support, the second cycloidal gear support, the first cycloidal gear support roller assembly, the second cycloidal gear support roller assembly, the roller pin assembly, the cycloidal gear, the flange and the axial locking part are arranged in the shell. According to the technical scheme, the first cycloidal gear support cooperates with the cycloidal gear and the rear end cover, and the second cycloidal gear support cooperates with the cycloidal gear and the flange, so that the hinge moment and bending moment bearing capacity of the steering engine are remarkably improved, and the steering engine has the advantages of being high in rigidity and precision and simple and compact in structure; and the electric steering engine can realize high-bearing and high-precision operation in a narrow space.

Description

technical field [0001] The invention relates to the technical field of aircraft rudder surface control, in particular to a cycloidal pinwheel deceleration electric steering gear. Background technique [0002] The function of the electric steering gear in the field of aerospace is to deflect the rudder surface of the aircraft, which has achieved the purpose of controlling the flight attitude of the aircraft. The electric steering gear is composed of three parts: servo motor, deceleration mechanism and position sensor. The deceleration mechanism is generally realized by a) harmonic reducer or b) ball screw + connecting rod mechanism. Most of the small and low-power electric steering gears use Most of the harmonic reducers with high power use ball screw + connecting rod mechanism. The harmonic reducer is small in size and light in weight. Because the principle is flexible transmission, its torque carrying capacity is limited, and when the harmonic reducer is subjected to a ben...
