Isicelo
Amabhithi e-Tricone, abanye abangase futhi bawabize ngokuthi ama-roller cone bits noma ama-tri-cone bits, anamakhoni amathathu.Ikhoni ngayinye ingazungeziswa ngayodwana lapho intambo yokubhoboza izungeza umzimba webhithi.Ama-cones anama-roller bearings afakwe ngesikhathi sokuhlanganiswa.Izingcezu zokusika ezigoqayo zingasetshenziswa ukubhola noma yikuphi ukwakheka uma kukhethwa umsiki ofanele, i-bearing, ne-nozzle.
Izici
1. Amandla nokumelana nokugqoka kokufakwayo kuyathuthuka ngokusebenzisa ukufakwa kwe-carbide okunamandla aphezulu nokumelana nokugqoka okuphezulu.
2. Indawo yokushisa enembayo enembayo ephezulu ephathwa ngokusebenzisa inqubo yokwelapha ukushisa okuthuthukisiwe ukuze kuthuthukiswe umthamo womthwalo kanye nempilo yesevisi yebheringi.
3. Impilo yesevisi ye-bearing iyanwetshwa ngokuthatha impahla eqinile futhi ekwazi ukumelana nokuguga ukuze ithwale i-thrust bear.
4. Lolu chungechunge uwoyela kahle rock bit ukusebenzisa uphawu roller eziveza isakhiwo.Njengoba ama-roller ahlelwe ngama-grooves ahlehlisiwe emzimbeni we-cone, usayizi wejenali ephethe uyakhuphuka.
6. Izindawo ezithwala i-thrust zibhekene kanzima futhi ziphathwa ngobuchwepheshe bokunciphisa ukungqubuzana.
7. Izingcezu zokubhoboza ezijikelezayo zisebenzisa ijenali.Indawo enekhanda elibhekene nobuso obunzima.I-cone ene-cone ehlanganiswe ne-friction reduction alloy bese i-silver-plated.Umthamo womthwalo kanye nokumelana nokubanjwa kwe-bearing kungcono kakhulu.
