Roller liketaneke likarolo tsa bohlokoa lits'ebetsong tse ngata tsa mochini, tse fanang ka phetisetso ea matla e tšepahalang le e sebetsang hantle. Liketane tsena li sebelisoa haholo liindastering tse fapaneng tse kenyeletsang likoloi, tlhahiso le temo ka lebaka la ho tšoarella ha tsona le bokhoni ba ho jara meroalo e phahameng. Leha ho le joalo, ho netefatsa ts'ebetso e nepahetseng le bophelo bo bolelele, litekanyetso tse khethehileng tsa tlhahlobo li tlameha ho lateloa. Sengoliloeng sena se shebana le ho rarahana ha liketane tsa lirolara mme se fana ka lintlha tsa bohlokoa tsa tlhahlobo tse lokelang ho lateloa ho boloka ts'ebetso ea tsona.
####Ketane ea rolara ke eng?
Rolara ke ketane e atisang ho sebelisoa bakeng sa phetisetso ea matla ea mochini mecheng e fapaneng ea lapeng, ea indasteri le ea temo. E na le letoto la lirolara tse khutšoane tsa cylindrical tse ts'oaroang hammoho ka lihokelo tsa mahlakore. E tsamaisoa ke likere tse bitsoang sprockets. Liketane le li-sprockets li sebetsa hammoho ho fetisetsa matla a ho potoloha ho tloha sefateng se seng ho ea ho se seng, hangata ho fokotsa lebelo le ho eketsa torque ts'ebetsong.
Liketane tsa lirolara li ratoa ka lebaka la bonolo, bokhoni le bokhoni ba ho sebetsana le meroalo e phahameng. Li tla ka boholo le litlhophiso tse fapaneng, e 'ngoe le e' ngoe e etselitsoe ho fihlela litlhoko tse itseng tsa ts'ebetso. Mefuta e tloaelehileng ka ho fetisisa e kenyelletsa liketane tse nang le strand e le 'ngoe, li-double-strand, le li-roller tse tharo, e' ngoe le e 'ngoe e fana ka maemo a fapaneng a matla le ho tšoarella.
Bohlokoa ba ho hlahloba ketane ea rolara
Ho hlahloba khafetsa ketane ea hau ea roller ho bohlokoa ka mabaka a 'maloa:
- Tšireletseho: Ho hloleha ha ketane ea lirolara ho ka baka ho hloleha ho hoholo, ho beha likotsi tse kholo tsa polokeho ho basebelisi le mechini.
- Ts'ebetso: Ho hlahlojoa khafetsa ho netefatsa hore ketane e sebetsa hantle, e boloka lebelo le torque e hlokahalang.
- Nako e telele: Ho tsebahatsa pele le ho rarolloa ha moaparo ho ka lelefatsa bophelo ba ketane ea rolara le ho fokotsa tlhoko ea ho nchafatsa khafetsa.
- Katleho ea Litšenyehelo: Tlhokomelo e thibelang ka ho hlahlojoa khafetsa e boloka litšenyehelo tse amanang le ho senyeha ho sa lebelloang le litokiso.
####Maemo a tlhahlobo a rolara
E le ho boloka ts'ebetso le polokeho ea liketane tsa li-roller, litekanyetso tse 'maloa tsa tlhahlobo li thehiloe. Litekanyetso tsena li fana ka tataiso mabapi le mokhoa oa ho hlahloba, ho lekanya le ho lekola boemo ba liketane tsa lirolara. Mona ke tse ling tsa lintlha tsa bohlokoa tse akarelitsoeng ke litekanyetso tsena:
- Tlhahlobo ea pono
Tlhahlobo ea pono ke mohato oa pele oa ho lekola boemo ba ketane ea hau ea rolara. E akarelletsa ho hlahloba matšoao a totobetseng a ho tsofala, ho senyeha, kapa ho kheloha. Libaka tsa bohlokoa tseo u ka li hlahlobang li kenyelletsa:
- Roller: Sheba hore na ha ho na matšoao a ho tsofala, mapetsong kapa ho senyeha.
- PIN: Sheba hore na ha e senyehile, ha e kobehe kapa ha e ruso.
- BUSHING: Sheba hore na ha o apare kapa o otlolla.
- Liphanele tsa Mahlakoreng: Sheba hore na ha ho na mapetsong, ho kobeha kapa tšenyo e 'ngoe.
- Li-Sprockets: Etsa bonnete ba hore meno ha a koaheloe kapa ha a senyeha 'me a kopanya hantle ka ketane.
- Tekanyo ya bolelele ba ketane
Ketane elongation ke bothata bo tloaelehileng bo hlahang ka lebaka la ho roala pakeng tsa pin le bushing. Ha nako e ntse e ea, ho apara hona ho ka etsa hore ketane e otlolle, e lebisang ho se sebetse hantle le ho hlōleha ho ka bang teng. Teko ea ho lelefatsa ketane e kenyelletsa ho metha bolelele ba palo e boletsoeng ea lihokelo tsa ketane le ho e bapisa le bolelele ba pele. Moeli o amohelehang oa ho lelefatsa hangata o haufi le 2-3% ea bolelele ba pele. Haeba elongation e feta moeli ona, ketane e lokela ho nkeloa sebaka.
- Tlhahlobo ea Lubrication
Lubrication e nepahetseng e bohlokoa bakeng sa ts'ebetso e bonolo ea liketane tsa rolara. Nakong ea tlhahlobo, hlahloba maemo a lubrication 'me u netefatse hore ketane e tlositsoe ka ho lekaneng. Lubrication e sa lekaneng e ka lebisa ho khohlano e ntseng e eketseha, ho felloa ke matla 'me qetellong e hlolehe. Sebelisa litlolo tse khothalelitsoeng 'me u latele litataiso tsa nako ea nako ea ho tlotsa.
- Khatello le Boiketlo
Khatello e nepahetseng le ho tsamaisana hantle ke tsa bohlokoa bakeng sa ts'ebetso e nepahetseng ea liketane tsa roller. Nakong ea tlhahlobo, hlahloba tsitsipano ea ketane ho etsa bonnete ba hore ha e thata haholo kapa ha e hlephile haholo. Ketane e tiileng haholo e ka baka ho senyeha ho feteletseng le khatello ea likarolo, ha ketane e hlephileng e ka baka ho thella le ho se sebetse hantle. Hape, etsa bonnete ba hore ketane e tsamaisana hantle le li-sprockets ho thibela ho apara ho sa tšoaneng le tšenyo e ka bang teng.
- Apara Litekanyo
Litekanyo tsa ho roala li kenyelletsa ho hlahloba botenya ba li-roller, li-pin le lihlahla. Sena se ka etsoa ho sebelisa li-calipers kapa micrometer. Bapisa litekanyo le litlhaloso tsa moetsi ho fumana hore na karolo e ka har'a meeli e amohelehang ea ho apara. Haeba ho roala ho feta meeli e boletsoeng, likarolo tse amehang li lokela ho nkeloa sebaka.
- Tlhahlobo ea Mokhathala le Corrosion
Mokhathala le kutu li ka ama haholo ts'ebetso ea ketane ea rolara le bophelo. Nakong ea tlhahlobo, sheba matšoao a mokhathala, a kang ho phunyeha kapa ho phunyeha ka mahlakoreng a mahlakoreng kapa lithapo. Hape, hlahloba ho bola, haholo-holo libakeng tseo ketane e pepesehang mongobo kapa lik'hemik'hale. Corrosion e ka fokolisa ketane 'me ea baka ho hloleha pele ho nako.
- Tlhahlobo ea Sprocket
Li-sprocket li bapala karolo ea bohlokoa ts'ebetsong ea liketane tsa roller. Nakong ea tlhahlobo, hlahloba sprocket bakeng sa matšoao a ho senyeha, joalo ka meno a hoketsoeng kapa a tsofetseng. Etsa bonnete ba hore sprocket e tsamaisana hantle le ketane mme ha ho na papali e feteletseng kapa ho sisinyeha. Li-sprockets tse tsofetseng kapa tse senyehileng li lokela ho nkeloa sebaka ho thibela tšenyo e eketsehileng ea ketane.
ha re phethela
Liketane tsa lirolara ke karolo ea bohlokoa lits'ebetsong tse ngata tsa mochini, tse fanang ka phetisetso ea matla e tšepahalang le e sebetsang hantle. Leha ho le joalo, ho netefatsa ts'ebetso e nepahetseng le bophelo bo bolelele, litekanyetso tse khethehileng tsa tlhahlobo li tlameha ho lateloa. Litlhahlobo tsa khafetsa tsa pono, litekanyo tsa ho lelefatsa ketane, licheke tsa ho tlotsa, litekolo tsa tsitsipano le tekano, litekanyo tsa moaparo, le mokhathala le ho chekoa ha kutu kaofela ke lintlha tsa bohlokoa tsa ho boloka liketane tsa rolara.
Ka ho latela litekanyetso tsena tsa tlhahlobo, basebelisi ba ka tseba le ho rarolla mathata a ka bang teng esale pele, ho netefatsa polokeho, ts'ebetso le nako e telele ea liketane tsa bona tsa rolara. Mokhoa ona oa ts'ebetso ha o ntlafatse ts'ebetso ea litsamaiso tsa mochini feela empa hape o fokotsa kotsi ea ho senyeha ho sa lebelloang le litokiso tse bitsang chelete e ngata. Qetellong, ho latela litekanyetso tsena tsa tlhahlobo ke ntlha ea bohlokoa ho holisa boleng le ts'epahalo ea liketane tsa lirolara lits'ebetsong tse fapaneng tsa indasteri.
