Product name: Trenchless tooth wheel palm piece, welded tooth wheel palm piece
With the in-depth use and development of the tricone drill bits, it has shown extraordinary results in several fields! Here we briefly describe the exploitation of the dental wheel palm piece!
Product characteristics various types of insert tooth wheel palm.

1. The bearings are high precision mating radial sliding, two way thrust bearings.
2. High precision rubber seals are used.
3. Steel ball locking tooth wheel to adapt to high speed.
4. Adopting full rubber reservoir bladder which can limit the differential pressure and prevent drilling fluid from entering the lubrication system, providing a good lubrication guarantee for the bearing system.
5. A new type of grease that can withstand high temperatures of 250°C and resists wear is used.
6. The high strength and high toughness carbide teeth are used in the inserted drill bit. The optimized design of the number of tooth rows, number of teeth, height of exposed teeth and the unique shape of the alloy teeth give full play to the high wear resistance and excellent cutting ability of the inserted drill bit.

Application areas are rotary excavation, bridge construction, trenchless construction, underground tunnels, assembly bits for construction civil engineering, foundation pile bits and reaming bits for drilling into a variety of different complex strata.

1. Main use: The tooth wheel palm is mainly used for assembling non-conventional size drill bits, assembly drill bits, machine pile drill bits and reaming drill bits.
2. Cutting structure: New formula and new process of high quality hard gold teeth are adopted to enhance the comprehensive mechanical properties of the cutting teeth.
3. Diameter-keeping structure: Multiple diameter-keeping structures are adopted: the outer row of the tooth wheel is set with trimmed teeth (GT teeth), the back of the wheel and the back of the claw are set with hard gold teeth and overlayed with maro-resistant alloy, and the tip of the claw is strengthened and the front side is welded, which greatly improves the diameter-keeping capacity of the drill.
4. Bearing structure: High precision radial sliding and two thrust bearings are used, with tight steel balls. The large journals of the jaws and the two stop surfaces are welded with wear-resistant alloy, and the large holes of the tooth wheel and the two stop surfaces are inlaid with special alloy and plated with silver to increase the wear resistance and anti-bite ability of the bearing subs and improve the ability of the bearing subs to adapt to high speed.
