英文: Based on the tribological principle and the theory of contact mechanics,it is feasible to adopt curvature-changing structure in the Rock-bit journal bearing system.The structure and coupling relationship of curvature-changing journal bearing under the con
中文: 基于摩擦学原理和接触力学理论,提出了可在牙轮钻头滑动轴承中采用变曲率结构.在不考虑摩擦的情况下，就结构设计和配合关系等问题进行了分析讨论，划分了准变曲率、吻合变曲率以及间隙变曲率等3种结构形式；针对考虑摩擦时的变曲率结构，提出了接触形状优化和预磨合的实施方案.钻头轴承试验结果表明，无论是预设计变曲率还是预磨合变曲率，都能改善轴承摩擦副的摩擦学特性，因而值得进一步研究和推广.
