Sebopeho le litšobotsi
Ho fihlela joale, sebopeho sa mafura a graphite ha se tlas'a melao e thata. Esita le GOST 3333-80, e ileng ea nkela sebaka sa khale sa GOST 3333-55, ha e thehe sebopeho sa boleng kapa boleng ba likarolo tse sebelisoang ha ho etsoa grease ea graphite. Tekanyetso e bontša feela litšobotsi tse akaretsang tsa mofuta oa grease oa graphite "USsA" le thepa e nyane e hlokahalang.
Sena se sebelisoa ke bahlahisi, ba leka ka sebopeho 'me, ka lebaka leo, thepa ea ho qetela ea sehlahisoa. Kajeno, likarolo tse peli tsa mantlha tsa grease ea graphite ke lintho tse peli: setsi sa liminerale se teteaneng (hangata se tsoa ho petroleum) le graphite e fatše hantle. Sesepa sa calcium kapa lithium, khatello e feteletseng, antifriction, ho hasana ha metsi le lisebelisoa tse ling li sebelisoa e le li-additives tse eketsehileng.
Ka linako tse ling phofo ea koporo e kenngoa ho graphite. Joale mafura a bitsoa koporo-graphite. Bophahamo ba grease ea koporo-graphite bo fetohela ts'ireletsong ea nako e telele ea libaka tse hokahaneng ho tsoa ho kutu e nang le ho falla ho fokolang. Ka mohlala, lubricant e joalo e sebelisoa haholo lihokelong tsa likhoele le litataiso tse fapaneng.
Litšobotsi tsa mafura a graphite, ho itšetlehile ka sebopeho, li fapane haholo. Ka mohlala, mocheso o fokolang oo lubricant e sa lahleheloeng ke thepa ea oona e fapana ho tloha ho -20 ho ea ho -50 ° C. Boholo: ho tloha ho +60 (bakeng sa lubricant e bonolo ka ho fetisisa ea UssA) ho ea ho +450 (bakeng sa "graphite" ea morao-rao ea theknoloji e phahameng).
E 'ngoe ea litšobotsi tse hlahelletseng tsa grease ea graphite ke coefficient e tlase ea likhohlano. Sena se finyelloa ka lebaka la graphite, lipoleiti le likristale tseo boemong ba limolek'hule li phallang hantle ka bobeli le ka holim'a tse ling, ho sa tsotellehe hore na libaka tsena ke tsa mofuta ofe. Leha ho le joalo, ka lebaka la ho thatafala ha likristale tsa graphite ka bomong, grease ena ha e khothalletsoe hore e sebelisoe likarolong tsa likhohlano tse nang le ho nepahala ho phahameng ha tlhahiso le likheo tse nyenyane pakeng tsa likarolo tse amanang. Ka mohlala, ho 'nile ha pakoa hore ho beha "graphite" ho e-na le li-grease tse ling tse loketseng (solidol, lithol, joalo-joalo) ka li-rolling bearings ho fokotsa bophelo ba bona ba tšebeletso.
Graphite e boetse e etsa qeto ea thepa ea conductive ea lubricant. Ka hona, mafura a graphite a sebelisoa ho sireletsa likhokahano tsa motlakase ho senya le ho eketseha ha tlhase.
E sebelisetsoa eng?
Bophara ba setlolo sa graphite hangata bo pharalletse haholo. Graphite e ipakile e le hantle ka lipara tse bulehileng tsa likhohlano, moo lebelo la ho sisinyeha ha likarolo li leng nyane. Ha e hlatsoe ka metsi ka nako e telele, ha e omelle ebile ha e fokotsehe tlas'a tšusumetso ea lintho tse ling tse mpe tse ka ntle.
Likoloi tse tloaelehileng le literaka, mafura a graphite a boetse a sebelisoa haholo:
- likhoele tse khoele - ho hanela kutu le ho khomarela likhoele;
- li-ball bearings tsa mabili a tsamaisoang - joalo ka setlolo se seholo, se pompeloa 'meleng oa li-bearings ebe se kenngoa ka tlas'a li-anthers;
- manonyeletso a molamu le malebela - a sebelisoa ka tsela e ts'oanang le li-ball bearings;
- likhokahano tsa spline - li-spline tsa kantle le tsa kahare li tlotsoa ho fokotsa moaparo nakong ea ho sisinyeha ha tsona;
- liliba - liliba ka botsona le li-anti-creak substrates li tlotsoa;
- mabitso - e le molao, tsena ke li-terminals tsa betri, terata e mpe ho tloha betri ho ea 'meleng le terata e ntle ho tloha betri ho ea ho ea qalang;
- e le lera la anti-creak mabapi le ho kopana le bokaholimo ba polasetiki le tšepe.
Leha taba ea hore kajeno 'maraka o fana ka mefuta e mengata ea litlolo tse tsoetseng pele le tse ikamahanyang le maemo, graphite e ntse e hlokahala har'a bakhanni ba likoloi. Ke tekano e ntle pakeng tsa theko le likarolo. Ka karolelano theko ea ligrama tse 100 tsa lubricant ea graphite e fetoha ho pota li-ruble tse 20-30, tse theko e tlaase haholo ho feta lipina tsa sejoale-joale tsa lubricant tse nang le litšobotsi tse ntlafalitsoeng. 'Me moo tekanyo e phahameng ea tšireletso e sa hlokeheng, tšebeliso ea graphite e tla ba tharollo e utloahalang ka ho fetisisa.
