Cone bit with good structuralcharacteristics:
1 with the rolling cone bit sealed bearing, cylindricalroller body rolling groove is placed, , with better performance in use.
(2) In sub-cone bit thrust bearing surfacesrespectively antifriction treatment and hardening, hardening anti-drillprotection.
3 using can withstand 250 ° C high temperaturewear resistance of the new grease.
4 using the differential pressure limit andprevent the drilling fluid into the lubrication system.Improved conebitsoil capsule full rubber, the bearing lubrication systemprovides a good guarantee.
Tricone rock bit of both the advantages and PDC drillbits, tricone bit more than for both strength and ductility are largeformations, but also can be applied to PDC bit difficult to deal with hardinterlayer and other complex formation.
