The invention discloses a transmission mechanism for a seeker servo system, and belongs to the field of electromechanical precise servo. The mechanism comprises a mechanism main body, a central frameassembly, an outer frame assembly, and a pull rod assembly. Through the matching connection of an azimuth main rotating shaft, an azimuth shaft and a pitching shaft, a parallel four-bar mechanism is formed to transmit a driving force to a load assembly, thereby achieving the azimuth motion, pitching motion and azimuth pitching coupling motion of the load assembly. According to the invention, through the optimization of the connection mode of all parts, the mechanism effectively improves the assembly process, and reduces the assembly cost. Moreover, a corresponding bearing and a corresponding limiting column are set for assisting the transmission of the mechanism, thereby greatly guaranteeing the precision and stability of the transmission mechanism in the transmission process, greatly improving the working capability of the servo system, enlarging the searching motion range of a seeker in a limited space, and enlarging the application range of the transmission mechanism of the servo system.
Description
technical field [0001] The invention belongs to the field of electromechanical precision servo, and in particular relates to a transmission mechanism of a seeker servo system. Background technique [0002] The servo system is developed along with the application of electricity. Driven by the new technology revolution in recent decades, especially with the rapid development of microelectronics and computer technology, servo technology has been widely used. The servo system is generally an electromechanical system combined with a mechanical device and a control system. Through the control system, various control parameters are input to the servo system, so that the mechanical device can realize various mechanical movements or mechanical operations. [0003] The seeker servo system is a servo system used to keep the microwave front end (or optical instrument) stable and achieve the target tracking task. The traditional seeker servo system transmission mechanism can be divided ...
