The input gear is meshed with a final-stage output shaft gear of the rotary table, rotating motion of the rotary table is transmitted to the input shaft, the shaft gear on the input shaft is respectively meshed with the angle measuring gear of the angle measuring mechanism and the limiting gear of the electricallimiting mechanism, and angle measuring and electrical limiting of the rotary table are respectively achieved through the angle measuring mechanism and the electrical limiting mechanism. Reasonable configuration can be carried out according to the structural layout requirement of the rotary table, and the functions of detecting the position and the speed of the last-stage output shaft of the rotary table and electrically limiting the limit angle position of the rotary table are achieved and the limit angle range of the electrical limit of the rotary table can be adjusted according to requirements.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a configurable modular turntable angle measurement and electrical limit composite mechanism. Background technique [0002] In industries such as communications and radar, a reciprocating turntable with a limit rotation angle greater than 360° is required to carry antenna feeders and front-end equipment to search and track target signals. [0003] In order to improve the search and tracking accuracy, it is necessary to set up an angle measuring mechanism on the turntable to accurately measure the final rotation speed and position of the turntable, and the servo control system can accurately control and compensate the movement of the turntable according to the measurement data. [0004] Most turntables use software limit, electrical limit and mechanical limit measures to ensure the safety and reliability of system equipment. Both the software limit and the electric...

Problems solved by technology

[0015] Since the traditional angle measurement and electrical limit functions usually adopt a separate structure, it cannot meet the needs of reciprocating turntable angle measurement and electrical limit angle range adjustment with a limit angle range greater than 360° at the same time, and the engineering implementation is more difficult
