摘　　要：提出了将智能全微机化传动误差检测仪器(iFMT仪器)以仪器单元的形式嵌入蜗轮母机各环节,再采用动态检测技术贯穿精密蜗轮副形成全过程的全新工艺。在iFMT仪器的实时监测下,实现了各环节独自精度的提高,尤其是通过诱导相关误差的改变来抵消其原始误差,从而显著降低对高端加工装备和个人特殊技能的要求。研究结果表明:蜗轮与蜗杆及刀具的成套性、测试仪器与辅助测试装置的成套性、尤其是测试技术与加工工艺的成套性,可保证所提新工艺能任意复制、放大或移植到其他相类似的应用场合。A new technology was proposed for embedding intelligent full micro-computerized transmission error testing instrument(iFMT instrument)into each link of worm gear master hobbing machine in the form of instrument unit,and dynamic detection technology was used through the whole processes of forming precision worm gear pair.Under the real-time monitoring of iFMT instrument,the independent accuracy of each link was improved,especially by inducing the changes of relevant errors to cancel their original errors,thus significantly reducing the requirements for high-end processing equipment and personal special skills.The results show that adaptive characters of worm gear,worm and cutter,testing instruments and auxiliary testing devices,especially testing technology and processing technology,may guarantee that the proposed new technology may be arbitrarily copied,enlarged or transplanted to other similar application fields.
