摘　　要：本文阐述了雷达方位回转±270˚时,一种安全保护装置的设计方法。当雷达方位±270˚回转时,通过方位转盘上的齿轮,带动左、右安全保护装置上的丝杠转动,丝杠带动螺母平动。利用左、右丝杠旋转方向的不同,安装在左、右螺母上的机械缓冲器随着丝杠转动上下平动,近角度的机械缓冲器下降,方位转盘不被阻挡继续转动,远角度的机械缓冲器上升,方位转盘上的凸块与远角度的机械缓冲器碰撞,使方位转盘无法继续回转,实现±270˚机械限位。This paper describes the design method of a safety protection device when the radar azimuth rotates ±270˚. When the radar rotates in azimuth ±270˚, the gear on the azimuth turntable drives the lead screw on the left and right safety protection devices to rotate, and the lead screw drives the nut to move horizontally. Using the different rotation directions of the left and right lead screws, the mechanical buffer installed on the left and right nuts moves up and down with the rotation of the lead screw, the mechanical buffer at the near angle decreases, the azimuth turntable continues to rotate without being blocked, the mechanical buffer at the far angle rises, and the boss on the azimuth turntable collides with the mechanical buffer at the far angle, so that the azimuth turntable cannot continue to rotate, achieve ±270˚ mechanical limit.
