Design of arc-tooth servo structure for a missile-borne radar seeker

摘要

The seeker servo system is one of the core components of the machine-driven seeker system, and its performance directly affects the overall performance of the seeker system. In this paper, in order to improve the transmission accuracy of a missile-borne radar seeker servo system, a transmission combination form of a double-torque motor transmission and a pitch-to-two-tooth transmission in the azimuth direction is proposed. The transmission mode of the double-tooth differential tooth backlash, the servo system has the characteristics of compact structure and high transmission precision. The feasibility and reliability of the structural design were verified by the mechanics analysis.
