1) annular groove
内环槽
1.
Secondly, a mathematic model was built to analyze the sealing performances for a S-DGS with an inner annular groove connected to the spiral groove on the face and the micro-groove structure parameters were optimized based on the rule of getting larger film stiffness or opening force while maintaining lower leakage.
其次,建立了带内环槽S-DGS端面气膜压力控制方程,并采用有限单元法求解,研究了低速低压条件下密封性能随端面微槽几何参数变化的规律,以获得较大气膜刚度或开启力以及较小泄漏量为几何结构优化原则,对微槽几何参数进行了优化。
2) Ring within the Groove
环形内槽
3) internal annular groove
内置圆环槽
1.
Two-step core-pulling method for shaping component with internal annular groove;
内置圆环槽结构的二步抽芯法
5) ring fillister
内凹环形槽
6) Annular tank process
内孔环形槽加工
