大模数(M=22)圆弧齿蜗轮减速器,是 BMD 铸造线上重要传动设备之一。该设备是从西德引进的,迄今已运转十多年了,而又未带备件,为确保铸造线的正常运行,需要一台这种减速器作为备件。与外商谈判,由于价格昂贵未谈成,为了节省外汇,经总厂和机动处有关单位研究决定,由我厂进行试制。圆弧齿蜗轮减速器试制的关键,是蜗轮副的制造,现将有关情况分述如下。 Large modulus (M = 22) arc gear reducer, is one of the important transmission equipment BMD casting line. The equipment was introduced from West Germany and has been in operation for over a decade without spare parts. One such reducer is required for the correct operation of the casting line. Negotiations with foreign companies, due to the expensive not talked about, in order to save foreign exchange, research and decision by the relevant units of the General Plant and the Maneuver Department, trial production by our plant. Arc tooth worm gear trial production of the key is the manufacture of worm gear, the relevant circumstances are as follows.
