摘要
为了使瞄准线瞄准目标并使图像稳定,在潜望式上反射镜系统中多采用1比2传动机构。调研了现有的一些1比2传动机构,对这些机构的优缺点进行分析,在现有结构的基础上进行改进,最终设计了一种新型的1比2传动机构。设计的新型传动机构为滚动轴承式三连杆机构,摆杆与转杆之间通过轴承连接,把滑动连接转变成滚动连接,尽量减小了摩擦力矩,从而达到更好的稳像效果。实验表明,设计的1比2传动机构,结构简单、可靠性强、传递稳定性好、精度高且不受温度影响,能够很好的实现传递稳定精度。
In order to make the aiming line aim at the target and make the image stable,the 1:2 transmission mechanism is used in the periscope upper reverse mirror system.The existing 1:2 transmission mechanisms are in?vestigated and the advantages and disadvantages of these mechanisms are analyzed.On the basis of the existing structure,a new type of 1:2 transmission mechanism is designed.The designed new type of transmission mechanism is a rolling bearing three connecting rod mechanism,which is connected by the bearing between the swing rod and the rotor,and the sliding connection is transformed into a rolling connection.The friction torque is reduced as much as possible so as to achieve a better image stabilization effect.The experiment shows that the 1:2 transmission mecha?nism has simple structure,good reliability,good transmission stability,high precision and without the influence of temperature.It can achieve good transmission and stable accuracy.
