Main feature
1. Between back in gear and discharge gear cone added a row of trimming tooth, broken by its walls of the remainder of the rock, and reduce the back teeth and cone to shell cone wear, can improve mechanical penetration rate *9%.
2. The floating bearing structure technology. between the big shaft friction pair increased floating ring, between the two vice friction increased floating piece, make the original bearing composed by a pair of friction into two on friction pair, reduce the bearing vice relative linear velocity, reduce the friction surface temperature, improve the bearing PV value, the bearing can adapt to the high speed drilling process conditions.
3. Bearing the floating parts with high strength, high flexibility,
high resistant temperature, high wear resistance of the
characteristics of the new material and surface treatment of solid
lubricants.
4.Type O sealing ring adopted more wear high saturated NBR,
increase the sealing ring of section, sealing outside the area in
the increased seal small convex platform, improved the seal
reliability;
5. Increase the oil hole big shaft, make the bearing has better lubrication;
6. The steel ball lock, bit suitable for high speed;
7. Special steel teeth drill the size, in addition to increasing trimming tooth outside, but also improve the steel teeth shape and overlaying welding materials, in the tooth is used on the park row arc tooth Angle, increased the surfacing thickness, the cone part back surfacing welding crack resistance, impact resistance and wear resistance of composite materials.
