对滚动式步进冷床齿条齿形参数进行了理论研究，导出了轧件纯滚动条件；分析了齿条运动速度对齿形参数的影响；建立了常用轨迹冷床齿条参数计算公式，为该冷床设计和使用打下了基础
The tooth profile parameter of the rolling step-changed cooling bed was theoretically studied, and the pure rolling conditions of the rolling element were deduced. The influence of rack movement speed on the profile parameters was analyzed. The calculation formula of rack- Laid the foundation for the design and use of the cooling bed
