一、引言蜗杆砂轮磨齿机是一种高效率的生产机床,国内中小规格齿轮的制造行业都将其作为磨齿的主要设备。然而,现有的以齿轮传动链为主传动结构的蜗杆砂轮磨齿机,不论是瑞士NZA和AZA还是国产YA723B等,其工作精度一般为5～6级,磨后的齿面有鱼鳞状的磨削波纹,因而精度和齿面品质要求高的齿轮要用碟形砂轮磨齿机加工,但是其加工效率太低。为此,改进蜗杆砂轮磨齿机,
I. INTRODUCTION Worm grinding machine is a kind of high-efficiency machine tool. The domestic small and medium size gear manufacturing industries regard it as the main equipment for grinding gear. However, the existing worm wheel grinding machine mainly driven by a gear transmission chain, whether in Switzerland, NZA or AZA, or domestic YA723B, has a working precision of generally 5 to 6, and the ground tooth surface has fish scales Grinding ripples, and therefore the accuracy and quality requirements of the tooth surface gear grinding disc grinding machine, but its processing efficiency is too low. To this end, improve the worm wheel grinding machine,
