摘　　要：根据某40m天线工程的实际需要设计1种旋转换馈机构。该机构采用转盘旋转的方式实现不同馈源相互切换，通过该机构实现所需馈源的相心均能准确到达天线的焦点位置并锁定。本文对整个机构的结构形式、功能、主要部件运动学分析进行了阐述。A 40m antenna feed-switching mechanism is designed according to the actual engineering requirements. The mechanism using the way of rotating the turntable to achieve the changing-over of the multiple feeds. This mechanism guarantee the phase center of each feed can reach the focus position of the antenna accurately and be locked accordingly. The composition, function and kinematics analysis of main unit are also described.
