What is a tricon bit?
TRICONE BIT is a tool for drilling rock drills located in the mining and well -drilling industry. The bits consist of three rotating heads in the shape of a cone equipped with several rows of concentric teeth. The heads are tilted at an angle of approximately 45 ° and arranged around the bit body with their peaks pointing inwards towards each other. Each head is equipped with a bearing to ensure smooth rotation. The Tricone Bit is usually mounted at the end of the drill chain and turned against the face of the drill, causing the teeth on the heads to cut the material from the face and strengthen the drill hole.
This particular bit developed the Sharp-Hughes Tool Company engineers in 1933 using two conical bits of the company as a basic design. The original two conical design design represented a few contradictory rotating cones equipped with teeth rows. When he turned a hole against the rock at the end of the drilling string. TRICONE BIT followed the concept of design quite closely except adding a third bitHeads. This configuration has proved to be much more efficient, drilling faster and with less wear of individual bit heads.
The basic concept that promotes the efficiency of rotating tapered drills is the effect of a dual axis. When drilling, the bit body turns around its own axis, while the heads revolve around their angle to the axis of the body. This Multi -Action is a particularly efficient cutting mechanism, so Trikone is a common choice for deep drilling operations. The construction is also cost -effective because the three drill heads improve the ratio of bits to promotion.
TRICONE BITS consists of a cylindrical bit body equipped with three mounting points of the head arranged in the needle around its perimeter. The bit heads are cone -shaped and equipped with integral bearings that ensure smooth rotation during heavy loads. Heads are attached to the bit body at an angle of the approx45 ° and their top points pointing towards the center of the body. Each head is equipped with several concentric rows of hardened teeth, which form a bearing or cutting points of a bit.
6 The mill tooth has a flat wedge -shaped profile, while the type of insertion is a rounded cone shape. When it turns under pressure on the rocky surface, the teeth cause the type of material failure to cause the roof layer to cut at each bite rotation. Although the bit heads can be reconstructed when wearing, the heads are generally discarded as the teeth are worn or broken.
