本文阐述了坚硬岩石牙轮钻头在坚硬花岗岩中钻进时的运动状态及某些运动特性。发现一个牙轮钻头中的三个牙轮回转速度不相同.而不同类型牙轮钻头的牙轮转速也不相同。牙轮合金齿存在滑移。本文指出如何减少牙轮转速的差别及对牙轮钻头合金齿提出具体要求。
This article describes the kinematics and some kinematics of a hard rock roller bit as it drills in hard granite. It is found that the rotation speeds of the three cone rollers in one roller bit are not the same, but the roller cone rotation speed is also different for different types of roller cone bits. Roller alloy teeth slip. This article points out how to reduce the difference in cone speed and put forward specific requirements for roller bit alloy teeth.
