对国标中圆锥滚子轴承特征画法的探讨

摘要

国家标准中规定了圆锥滚子轴承的特征画法.通过将该画法中的矩形宽度与轴承实际宽度进行对比,发现了两个问题:对部分国锥滚子轴承而言,遵循该画法所得到的图与标准本身所表述矛盾;另外在装配图中不能正确地表达机器的装配关系.为此提出了解决问题的建议供参考.%In the Standard of P.R.C 《 GB/T 4459.7-1998 Mechanical drawings-Represent ation of rolling bearings》 , there is a convention in characteristic drawing of cone roller bearings. By contrasting the width of the drawing to the fact, the article points out two problems:to some cone Roller Bearings, the drawing can't express the principle of a mechanical system in the assembly drawing; and is contradictory to the words in this standard. The paper provides some suggestions to solve the problem.
