读了《机械制造》1990年第8期所刊登的广西柳州工程机械厂邓喜娟《车球形表面的简易装置》一文,介绍了结构简单、使用方便的车球形装置,确是一种比较好的加工方法。下面根据笔者的实际经验对该文补充几点注意事项。(1)靠模法所能加工的球形范围,一般以60°圆心角为好。因当超过此范围后,滚子所受的径向力逐渐减小,轴向力逐渐增加,机构必然被卡死不动,无法
Read “Mechanical Manufacturing” No. 8, 1990, published in Guangxi Liuzhou Construction Machinery Factory Deng Xijuan “car spherical surface of the simple device,” a text, introduced the simple structure, easy to use car ball-shaped device, is indeed a relatively good processing method. The following based on the author’s actual experience on the article to add a few notes. (1) by the mold method can be processed spherical range, generally 60 ° central angle as well. Because when more than this range, the roller radial force gradually reduced, the axial force gradually increased, the body must be stuck, can not
