Embodiment 1

[0028] Using the above scheme, the servo mechanism adopts a brushless torque motor direct drive structure, and the motor rotation position feedback adopts a resolver. The controller realizes the precise position control of the torque motor by solving the resolver position signal, and improves the computing power of the solver chip and the performance of the sensor. Accuracy can be obtained as high as arc classification motor rotation accuracy. The resolver rotor 21 and the resolver stator 16 are separately installed on the rotor assembly 14 and the resolver support 4, and the rotor assembly 14 is positioned on the housing assembly 10 and the resolver support 4 through bearings at both ends of the assembly, thereby ensuring that the resolver rotor 21 The coaxiality and positional degree with the resolver stator 16 ensure the accuracy of the resolver signal structurally.

Abstract

The invention provides an integrated high-thrust servo mechanism. The integrated high-thrust servo mechanism comprises a rotary transformer stator and a rotary transformer rotor, the rotary transformer rotor is fixed on the rotor assembly and is positioned on the inner ring of the rotary transformer stator; the rotary transformer stator is fixed to the rotary transformer support, and the rotor assembly is rotatably fixed to the rotary transformer support. And an angular contact ball bearing is arranged at the rear end of the resolver bracket and is fixed on the rotor assembly and the resolverbracket. Based on a transmission structure directly driven by a brushless torque motor and in combination with a shaft transmission structure of a planetary roller screw, the weight of the whole machine is effectively reduced, and a servo mechanism with high thrust linear output is obtained, so that the problems that a linear thrust servo mechanism is insufficient in thrust, large in return difference, low in precision and short in system service life are solved.

Description

technical field [0001] The invention relates to an integrated high-thrust servo mechanism. Background technique [0002] With the development of aviation and aerospace technology, the engine is the only power source of the system, and its thrust and life are continuously improved, which puts forward higher requirements for the peripheral servo system of the engine nozzle. Not only the requirements for the dynamic response characteristics and output thrust of the system are getting higher and higher, but also the volume and weight of the servo mechanism are also higher and higher. As the core unit of the fast-response servo system, the current traditional linear servo mechanism has a thrust-to-weight ratio that is far from meeting the needs of current technological development. [0003] The existing linear thrust servo mechanism is driven by a servo motor, the gear is decelerated, and the ball screw is driven to obtain a linear thrust motion. The volume and weight are large,...
