摘　　要：按某型号便携式雷达支撑座设计指标要求，在方位传动结构中采用单蜗轮双蜗杆形式，分析了提高传动精度及减少回差的工作原理，俯仰传动结构中分析减小负载驱动力矩时，采用双扭转弹簧代替配重块形式。对方位及俯仰结构在环境适应性、角度检测反馈、限位形式等方面进行分析和论述，提出了优化的结构方案。In accordance with the requirements of design index of brackets a type portable radar in bearing structure in the form of single worm gear and worm transmission, Analyzes the transmission accuracy and reduce the working principle of the return difference pitch analysis reduces load driving torque transmission structure,Adopts double torsion spring instead of counterweight block form. Each other and pitch detection in environmental adaptability, Angle feedback structure, Limit form aspects are analyzed and discussed, Such as optimizing the structure of the scheme are put forward.

关 键 词：双蜗杆 回差 双扭转弹簧 限位形式
