Production process of cone bit & working principle of three cone bit
1. The basic structure of the three-cone bit: the bit body: there are three pieces of teeth assembled and welded together, and the upper part is connected with the screw thread cone: a conical metal body composed of the cone body and teeth. Two types of bearing and its oil storage sealing device nozzle
2. The working principle of the cone bit When the cone bit works at the bottom of the well, the overall rotation of the bit around the bit axis is called revolution, while the three cone bits roll at the bottom of the well according to their own axis, which is called rotation. The weight on bit is applied to the rock through the teeth, breaking the rock (crushing).
