U ka Rarolla Tšenyo ea ho Beha Joang ho Tricone Bit?

E le karolo ea mantlha ea ho cheka oli le khase le lisebelisoa tsa boenjiniere tse se nang trenchless, "pelo" eakotopo ea trilone. Leha ho le joalo, hangata e hloleha pele ho nako ka lebaka la maemo a tlase a tlase, e fetoha ntlha ea bohlokoa ea bohloko e thibelang katleho ea ho cheka.

Ho na le mabaka a mararo a mantlha a ho jara tšenyo: 

Ntlha ea pele, khatello e phahameng ea mali le khatello e fapaneng ea khatello e tlase. The radial runout le axial extrusion eakhounenakong ea ho cheka ho ka baka habonolo mokhathala spalling ea bearing raceway; 

Ea bobeli, tlhaselo ea mokelikeli oa ho cheka le li-cuttings. Litiiso tsa setso ha li khone ho arola litšila ka katleho, tse lebisang ho roala ho hoholo ha li-bearings; ea boraro, ho hloleha ha lubrication. Libakeng tse nang le mocheso o phahameng le o nang le khatello e phahameng, mafura a lubricating a hlapolloa habonolo kapa a khabone, a lahleheloa ke ts'ireletso ea ona.

E le ho sebetsana le lintlha tsena tsa bohloko, Drillmore e thehile mekhoa e meraro ea mantlha e lebisitsoeng ho ntlafatsa ka botlalo boleng ba ho jara. 

Taba ea pele, re amohela a mokhoa oa ho matlafatsa carburizing bakeng sa tšepe e phahameng ea carbon chromium, e eketsang boima ba holim'a sefahleho ho ea holimo ho HRC62 ha e ntse e boloka ho tiea ha motheo, ho finyella ntlafatso e 'meli ea ho hanyetsa tšusumetso le ho hanyetsa ho apara. 

Ea bobeli, re iqapetse a multi-channel labyrinth seal + e phahameng-khatello lubrication tsamaiso e kopantsoeng, e khethollang ka katleho tlhaselo ea mokelikeli oa ho cheka le ho tsoela pele ho tlatsana le mafura a mocheso o phahameng oa mocheso ho qoba ho hlōleha ha lubrication. 

Ea boraro, re ntlafalitse boemo ba spherical roller bearing structure ho arolelana mojaro ka tsela e lekanang tseleng eohle ea peiso le ho fokotsa khatello ea maikutlo ea lehae.
