Steel tooth tricone bit can increase the bit's stability and lower the tooth impact load,
and enhance its wear resistance. The design of contrary turning with two lines of teeth
can reduce the teeth axial load and expand life of tooth bit bearing.
Structure features:
1. The sliding bearing form. Tooth palm bearing surface surfacing layer of hard alloy,
cone bearing with reduced after welding together gold for silver, improve the bearing
capacity and resistance to bite ability;
2.Bearing type O sealing ring is wear-resistant, high temperature resistant
high saturation NBR, increase the sealing ring section reduces the pressure seal,
carefully designed sealing convex platform outside the improved seal reliability.
3.USES the steel ball or card lock reed cone way, card lock can endure high reed
drilling pressure, steel ball to lock the can adapt to high speed.
4.The differential pressure and prevent drilling fluid restrictions in the lubricating system all rubber oil storage sac, for bearing system provides good lubrication guarantee.
5. 250 ° C temperature the high temperature, abrasion resistance of new grease.
6. Set foot drill using high strength and high toughness carbide gear, optimize the
design of the tooth row number, gear, toothy height and unique alloy tooth shape, give
full play to the set feet high wear resistance and excellent bit of cutting ability. Ruler
bit tooth face apply welding new wear-resistant materials, and to maintain
the mechanical drill bit ruler speed at the same time, improve the drill bit cutting
teeth life.
