基于一体化轴系的消像旋组件设计

介绍了一种基于一体化轴系设计的棱镜消像旋组件,以及光学装调方法。该组件可用于机载光电雷达、车载周视瞄准仪等光学系统中,解决了光学系统像方图像旋转的问题。该组件采用一体化轴系设计,即在主轴上直接加工出轴承内圈沟道;主轴、滚珠、保持架与轴承外圈一体化装配。同时棱镜组件可以在主轴内实现一维调整,以确保棱镜视轴与机械轴的重合。通过本文所介绍的光学装调方法,可以使消像旋组件棱镜的光轴回转精度达到±12″。相对于其他消像旋组件的轴系设计,具有精度高、稳定性强、体积小、质量轻、结构简单、易于装调等特点。

The design of elimination image rotation subassembly based on integrated shafting

A kind of elimination image rotation subassembly based on integrated shafting design,and its optical alignment method are described in the paper.This subassembly can apply to airborne photoelectricity radar,vehicle-borne panoramic sighting telescope and other optical system,and solves the problem of optical system image rotation.The subassembly uses integrated shafting design,that is,the bearing inner ring channel is machined directly on the main shaft,and the main shaft,bearing balls,and bearing outer ring and cage are integrated assembly.At the same time,the prism components can be adjusted in the main shaft on one-dimensional direction,which can overlap prism optical axis and mechanical axis.It can make the optical axis rotation precision of elimination image rotation subassembly prism achieving±12″through the alignment method introduced in this article.Compared with other elimination image rotation systems,it has characteristics of high precision,strong stability,small volume,light weight,simple structure and easy to align.
