摘要
本文提出并分析:用遵守包容原则的线位置度公差表示螺纹的螺距和牙型半角误差;用动态公差带描述螺纹合格的条件。
In this paper, the authons put forward and analyse the pitchand flank angle errors of thread expressed by the linear position toler-ance in accordance with the envelope principle, and the authors describethe qualifecl conolitions of thread expressed by the dynainic tolerancezone.
