C 6136车床可以加工螺距自0.3至10毫米的19种螺纹,但还有0.35、0.45、4.5和5.5五种标准螺距的螺纹不能直接按铭牌挂轮。我们采用比例法解决了这个问题。例如:加工螺距为3.5毫米的螺纹,可在铭牌上找出与它相接近的,螺距3毫米的挂轮为48/96·45/90=1/4,就可求出螺距3.5毫米的挂轮比 i。解时先列出比例式: The C 6136 lathe can machine 19 threads with a pitch of 0.3 to 10 mm, but there are also 0.35, 0.45, 4.5 and 5.5 five standard pitch threads that can not be driven directly on the nameplate. We used the proportional method to solve this problem. For example, a thread with a thread pitch of 3.5 mm can be found on the nameplate, and a hanging thread with a thread pitch of 3 mm is 48/96 · 45/90 = 1/4, and a thread pitch of 3.5 mm can be found Wheel ratio i. The solution is to list the proportions:
