本文主要介绍光学分度头和光学回轉装置在测量齿輪周节精度方面的应用;并着重地介绍了Leitz光学分度头的結构原理。一、绪言齿轮的周节和齿形是决定齿输精度最重要的参数。从而
This paper mainly introduces the application of the optical indexing head and the optical rotary device in the measurement of the accuracy of the gear section. The principle of the structure of Leitz optical indexing head is also introduced emphatically. I. INTRODUCTION The pitch and tooth shape of gear are the most important parameters that determine the accuracy of tooth transmission. thereby
