Daban-daban nau'ikan raƙuman dutse da tsarin lubrication na Roller Cone Drill Bits da ake amfani da su don kariyar bearings.Tsarin farko wanda ya haɗa da amfani da ruwan hakowa azaman mai mai, yayin da ƙarin tsarin kwanan nan yana amfani da mai don shafawa.Ruwan hakowa mai ɗauke da daskararru don zama iyakanceccen abu dangane da dogon gudu kuma ba kasafai ake amfani da shi azaman mai mai a cikin rago na yau ba.Misalin mazugi na tricone bits, ana ɗora bitar mazugi na nadi a kan mujallu kamar yadda aka nuna a ƙirar ƙasa.
Haɗa rago, Tricone bits Rock Roller Cone Drill Bit Bearing Design
Nau'o'in Nau'in Ƙirar Ƙira guda uku da ake amfani da su a cikin waɗannan tricone bits rock Roller Cone Drill Bits:
1.Roller bits bearings System, wanda ke samar da taro na waje don tallafawa nauyin radial (ko WOB)
2.Ball bearings System, wanda ke tsayayya da tsayi ko matsa lodi kuma yana taimakawa wajen tabbatar da cones a kan mujallu.
3.A gogayya Bearing System, a cikin hanci taro wanda taimaka wajen tallafawa da radial loading.Ƙunƙarar gogayya ta ƙunshi wani daji na musamman wanda aka matse cikin hancin mazugi.Wannan yana haɗuwa tare da fil ɗin matukin jirgi a kan jarida don samar da ƙarancin juzu'i don tsayayya da kamawa da lalacewa.
Duk kayan ɗamara dole ne a yi su da ƙarfe mai tauri wanda ke da babban juriya ga guntuwa da karyewa a ƙarƙashin nauyi mai tsanani dole ne su goyi bayan.Kamar yadda yake tare da duk abubuwan da aka haɗa nadirar mazugi, ana amfani da maganin zafi don ƙarfafa ƙarfe.
Abubuwan da ke da mahimmanci na ƙira na ƙungiyar bearings shine sararin samaniya.Da kyau maƙalar ya kamata ya zama babban isa don tallafawa nauyin da aka yi amfani da shi, amma wannan dole ne a daidaita shi da ƙarfin jarida da harsashi na mazugi wanda zai iya zama aikin diamita na mujallar da kauri na mazugi.
Zane na ƙarshe shine sasantawa wanda ke tabbatar da cewa, a zahiri, ƙwanƙwasa ƙwanƙwasa ba za su shuɗe ba kafin tsarin yanke (dukkan tricone bits, rock bits, nadi nadi rock drills bits ya kamata su shuɗe daidai).Koyaya, lodin keken keke da aka sanya akan bearings, a kowane yanayi, a ƙarshe zai fara gazawa.Lokacin da wannan ya faru an lalata ma'auni da daidaitawar taro kuma an kulle cones a kan mujallu.
