摘要
本文通过典型变焦距镜头的实例和图形,详细介绍了机械补偿变焦距镜头几种常用的变倍组和补偿组在变焦过程中往复运动导轨的结构形式,及其各种结构形式的优缺点。并论述了设计各种形式导轨机构应注意的问题。
By means of the examples and drawings of the typical zoom elns,this paper presents the types of the guide rail used for the reciprocating motionof the variable magnification unit and compensation unit in the machanicalcompensation zoom lens and their characteristics, also discusses the problemswhich should be noticed in the guide rail design.
