十字形鋼鉆頭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 condition without friction have been analyzed and three kinds of sub - form structure configurations, namely, the pseudo - curvature - changing structure, the conformable curvature - changing structure, and the clearance curvature - changing structure, been differentiated according to the contacting features. the shape optimization and pre - running - in regulations of the contact surface of curvature - changing journal bearing under friction condition have been established. the results of rock bit journal bearing test indicate that the tribological behavior of the bearing can be effectively improved by curvature change based on both designing and pre - running - in
基於摩擦學原理和接觸力學理論，提出了可在牙輪鉆頭滑動軸承中採用變曲率結構.在不考慮摩擦的情況下，就結構設計和配合關系等問題進行了分析討論，劃分了準變曲率、吻合變曲率以及間隙變曲率等3種結構形式；針對考慮摩擦時的變曲率結構，提出了接觸形狀優化和預磨合的實施方案.鉆頭軸承試驗結果表明，無論是預設計變曲率還是預磨合變曲率，都能改善軸承摩擦副的摩擦學特性，因而值得進一步研究和推廣Znd2160 complete crystal shape with full surface, good diaphaneity and low impurity, suitable for circular saws, frame - saw and geological broach
