【Abstract】 The reason that errors take place in machining process for the plane enveloped circular couple of worm and gear was analyzed. By means of the principle of special engagement, the normal chordal thickness was calculated for practical machining conditions. And then the machining dimensions of worm will be checked by the thickness calculated above. The purpose to control the machining errors of the worm manufactured was reached by adopting a series of technique measures to control the technology of manufacturing process strictly, and the test for the machined couple of worm and gear was conducted by using a setup of electric closed-circuit for couples of worm and gear. The result of the test was satisfactory.更多还原
