将尺寸链分析引入到道岔设计中,介绍了道岔设计尺寸链分析的基本方法,并应用该方法对道岔尖轨基本轨相对降低值尺寸链进行了具体分析,提出了道岔生产和组装过程中控制道岔组件配合公差的措施,为选配和修配在道岔生产和组装过程中的应用提供了理论依据。
The dimension chain analysis is introduced into the switch design. The basic method of dimensioning chain analysis of the switch is introduced. The relative reduction value chain of the basic rail of the switch rail is analyzed by this method. The control of switch manufacturing and assembly process The fitting of the turnout assembly with the tolerance measures provides a theoretical basis for the matching and repairing in the production and assembly process of turnout.
