1. Cutting Structure

Tailored to varying Mohs hardness levels in geological formations (rocks), our selection of alloy teeth and tooth profiles ensures optimal matching for wear resistance and toughness. Through computer-simulated bottom-hole crushing curves, we have engineered a rational tricone drill bit structure, optimizing tooth distribution to balance the workload of the drill bit. The installation of back-cone teeth involves placing a single row of back-cone teeth on the back cone of the tricone drill bit, reinforcing the stabilizing effect.

2. Bearing Structure

Our RS company offers two series of tricone drill bits: sealed and non-sealed (open).

Sealed Bearings: Employing O-ring seals, the sealed bearing system undergoes special treatment to maintain a lubricated friction state, reducing bearing wear and extending the bearing's lifespan. The structure comprises an O-ring seal, large roller bearing, steel ball, two thrust stops, sliding bearing (or small roller bearing), and a single thrust stop – a total of five bearing components. The O-ring seal isolates the bearing from the external environment, preventing debris, air, and water from entering the bearing.

Non-sealed (Open) Bearings: The non-sealed bearing system lacks seals and consists of a large roller bearing, steel ball, two thrust stops, sliding bearing (or small roller bearing), and a single thrust stop – five bearing components in total. A debris-deflecting tube prevents rocks from entering the bearing cavity. The cavity features a wind flow distribution system, where most compressed air is directed through three replaceable nozzles on the side of the bit, expelling debris from the annular space between the borehole wall and the drill rod to the surface. Another portion of the compressed air enters various parts of the bearing through a debris-deflecting tube and the bit body's wind channel, cooling the bearing and flushing away debris.

Our tricone drill bit structure incorporates tooth inlay, stabilizing teeth, and roller bearings, utilizing compressed air for efficient debris removal. This design boasts high penetration efficiency and reliable operation. Additionally, wear-resistant alloys and anti-wear alloys are welded and embedded on the tooth surface and tricone drill bit body bearing surfaces, enhancing load-bearing capacity and resistance to engagement.

3. Back Structure

Featuring an uplifting backplane design, we have increased debris evacuation space, accelerated debris removal, and minimized wear on the tricone drill bit caused by rock fragments. The back is clad with wear-resistant material, and the back tip and teeth are fitted with protective inlays, effectively safeguarding the back.
