Series type of cone bits are assembly parts of Tricone bit and hole opener,its the main cutting structure of a bit.
Cutting Structure
Reinforcing
the comprehensive mechanical properties of cutting tooth by using high
quality tungsten carbide inserts of new formula and new techniques of
insert bit.
Gauge Structure
The
multiple heel position with gauge trimmer on the heel, tungsten carbide
and hardfacing on the shirttail, strengthened spear point will enhance
the gauge protection.
Bearing Structure
High
precision journal bearing with two thrust faces. Ball locked cone.
Hardfaced head bearing surface. Cone bearing inlaid with friction
reducing alloy and then silver-plated. Abrasion resistance and seizure
resistance of the bearing are improved, and suitable for high rotary
speed.
Seal and Lubrication
The
advanced metal seal package is composed by two metal seals and two
elastic rubber energineers. The energizer and back-up ring will support
the pushing force to make the two metal faces tightly contact. In the
drilling, the metal seals are relevant moving, and the energizers are
static. This will increase the bearing seal reliability and durability.
The compensation system and the high quality bit grease can limit
pressure differential, and greatly increase the lubricating reliability.
