在引进国外电机技术中,我们分析了德国电梯电机轴瓦的图纸(图1),认为它的加工是不难的,但其中半径为28.8,偏心为2°38′的要求,一般车床不能加工。为此我们设计了一个偏心的夹具。经使用,效果很好。加工好的轴瓦经技术鉴定,质量完全达到了图纸的要求。现将设计中的一些体会介绍如下,供参考。 In the introduction of foreign motor technology, we analyzed the drawings of German motor bearings (Figure 1), that its processing is not difficult, but the radius of 28.8, the eccentricity of 2 ° 38 ’requirements, the general lathe can not be processed. To this end we designed an eccentric fixture. After use, the effect is very good. Well processed bearings identified by the technology, the quality of the drawing has fully met the requirements. Now the design of some of the experience introduced below, for reference.
