Structural Features

Tricone bits typically consist of cones, bearings, water passages, and nozzles. The core function is rock breakage through rotation and pressure. The cones are studded with cutting teeth that alternately contact the well bottom, effectively reducing wear and improving drilling efficiency. Tricone bits are classified by the number of cones: single, double, triple, and multiple, with tricone bits being the most common due to their good balance and high drilling efficiency.
The bearing system is a crucial component of the bit, typically using rolling or sliding bearings. The bearing inner race mates with the cone shaft, ensuring stability and wear resistance during high-speed rotation. The bit's locking system, including ball locking and thrust bearings, secures the cones and withstands axial loads.
