Iikhonkco zeRoller Chain Closed-Loop: Kutheni iLinki eziQhelekileyo zikhethwa?
Kwiinkqubo zothumelo lwemizi-mveliso, iiroller chain, njengezixhobo zothumelo lwamandla ezisebenzayo nezithembekileyo, zisetyenziswa kakhulu kwiindawo ezahlukeneyo, kubandakanya ukwenziwa koomatshini, izixhobo zezolimo, kunye nothutho. Kubathengi, ukukhetha iroller chain eneeparameter ezifanelekileyo kuchaphazela ngqo ukusebenza kakuhle kwezixhobo, iindleko zolondolozo, kunye nobomi benkonzo. Ngelixa ukukhetha inani lilonke leekhonkco kwi-closed-loop chain kunokubonakala kulula, kunengqiqo ebalulekileyo yobunjineli. Imvumelwano yeshishini ithi inani elifanayo leekhonkco liyathandwa kwiiroller chain. Esi sigqibo asingombandela; sisekelwe ekuqwalaselweni ngokubanzi kweempawu zesakhiwo seroller, ukusebenza kakuhle kothumelo, kunye nobomi benkonzo.
I. Isiseko soLwakhiwo kunye neMigaqo yoQhagamshelo lweeRoller Chains
Ukuze uqonde ingqiqo engundoqo emva kokukhetha amakhonkco, kufuneka kuqala uqonde isakhiwo esisisiseko se-roller chain. I-roller chain eqhelekileyo ineepleyiti zangaphakathi nezangaphandle, ii-pin, ii-bushings, kunye nee-roller. Ii-pins kunye nee-bushings ziyahambelana ukuze kuvumeleke ukujikeleza okuguquguqukayo kwamakhonkco akufutshane. Xa i-chain yenza i-closed loop, amakhonkco adibanisayo ayafuneka ukuze kuqinisekiswe iziphelo. Kukho iindlela ezimbini zokudibanisa eziqhelekileyo:
Iikhonkco eziqhelekileyo zokudibanisa (kwiikhonkco ezineenombolo ezifanayo kuphela)
I-pin yenziwe ngepleyiti yangaphandle yokudibanisa, ipleyiti yangaphakathi yokudibanisa, kunye nephini, i-pin iqiniswe nge-spring clip okanye i-cotter pin. Ulwakhiwo lwayo lufana nolwe-link eqhelekileyo kwaye isebenza kuphela njengendawo yokuvala ngexesha lokuhlanganiswa.
Amakhonkco otshintsho (kwiikhonkco ezineenombolo ezingaqhelekanga kuphela)
Xa inani lilonke leekhonkco lingaqhelekanga, kufuneka iikhonkco zotshintsho. Ezi khonkco zinepleyiti yokudibanisa yangaphandle egobileyo ngokupheleleyo, efuna uqhagamshelo ngaxeshanye phakathi kweekhonkco zangaphakathi nezangaphandle. Oku kubangela iimeko ezahlukeneyo zomthwalo kuneekhonkco eziqhelekileyo.
II. Iingenelo eziphambili zeTsheyini zeNani eliQhelekileyo: Ukusuka ekusebenzeni koomatshini ukuya kwixabiso elisebenzayo
1. Ukuphepha ii-Transition Links, Ukuphucula amandla apheleleyo
Iikhonkco zotshintsho zizinto ezimbi ezifunekayo kwikhonkco lamanani angaqhelekanga, kodwa zineengxaki ezinkulu zesakhiwo:
Iipleyiti zokudibanisa zangaphandle zeekhonkco zotshintsho mazimelane noxinzelelo lokugoba, ngelixa iikhonkco zesiqhelo zimelana noxinzelelo lokutsalwa. Oku kubangela ukuba iikhonkco zotshintsho zibe buthathaka nge-15%-20% kuneekhonkco eziqhelekileyo.
Phantsi kweemeko zesantya esiphezulu okanye umthwalo onzima, amakhonkco otshintsho angaba ngamanqaku abuthathaka ngokulula. Ekuhambeni kwexesha, anokuqhekeka okanye aphuke, nto leyo ebangela ukuba izixhobo zingasebenzi okanye iingozi.
Ukusebenzisa ityathanga leenombolo ezilinganayo kususa ngokupheleleyo ii-transition links, kuqinisekisa ukusasazwa komthwalo ngokulinganayo kuzo zonke ii-link, okuphucula kakhulu amandla etyathanga okuthwala umthwalo kunye nokumelana nokudinwa.
2. Ukunciphisa Uxinzelelo Lokudluliselwa Kweemoto kunye Nokunxiba Okunciphileyo
Ngexesha lenkqubo yokudlulisa, iiroller chains zifumana imithwalo yokwethuka rhoqo xa zidibanisa ii-chain links kunye namazinyo e-sprocket. Iindawo zokunxibelelana zee-chain links ezineenombolo ezifanayo zihambelana nesakhiwo se-chain link eqhelekileyo, nto leyo ebangela ukusasazwa okulinganayo ngexesha lokudibanisa ii-mesh. Nangona kunjalo, ii-transition links ezimile ngendlela engaqhelekanga zinokukhokelela ekulahlekelweni kokuchaneka kwe-mesh kwindawo ethile, zibangele ukuguguleka okukhulu kwii-roller, ii-bushings, kunye namazinyo e-sprocket, nto leyo enciphisa ubomi benkonzo ye-chain kunye ne-sprocket.
3. Ukufakwa nokugcinwa okulula, ukunciphisa iindleko
Iikhonkco zekhonkco ezineenombolo ezifanayo kulula ukuzidibanisa nokuzisebenzisa. Iikhonkco zokudibanisa eziqhelekileyo zinokufakwa kwaye zisuswe ngokukhawuleza kusetyenziswa izixhobo eziqhelekileyo, nto leyo esusa imfuneko yeenkqubo ezikhethekileyo.
Amakhonkco otshintsho afuna ulungelelwaniso olungqongqo ngexesha lokufakwa, kungenjalo anokubangela ukuba ityathanga liphambuke ngokulula kwaye lonyuse ubunzima bokugcinwa.
Ngokwembono yexesha elide, iikhonkco zeentambo ezilingana ngenani zinezinga eliphantsi lokusilela kunye nemijikelo yokutshintshwa emide, nto leyo enciphisa ixesha lokungasebenzi kwezixhobo kunye nokusetyenziswa kwezixhobo ezingasetyenziswanga, nto leyo enciphisa ngokungathanga ngqo iindleko zizonke zomthengi.
4. Iyahambelana nee-sprockets ezisemgangathweni, iphucula ukusebenza kakuhle kothumelo
Ii-sprockets zemizi-mveliso zihlala ziyilwe ngenani lamazinyo elilinganayo okanye elingaqhelekanga, kodwa ii-meshing frequency ze-sprocket kunye ne-chain kufuneka zihambelane ukuze kuthintelwe ukurhawuzelelwa. Ii-chains ezinenani elilinganayo lee-links zibonelela ngomjikelo we-meshing ozinzileyo ngakumbi ngee-sprockets, zinciphisa ukuguquguquka kwesantya okubangelwa zii-links ezingahambelaniyo kunye namazinyo e-sprocket, kwaye ziphucula ukusebenza kakuhle kothumelo nge-3%-5%. Zifanelekile ngokukodwa kwizixhobo ezifuna ukuchaneka kwesantya esiphezulu (ezifana nemigca yokuhambisa echanekileyo kunye noomatshini bokuprinta).
III. Izinto ekufuneka ziqwalaselwe xa kusenziwa isicelo
Ukulinganisela Inani leeLinks kunye nomgama weZiko
Xa ukhetha itsheyini enenani elilinganayo leekhonkco, cinga ngomgama ophakathi wesixhobo. Ukuba umgama ophakathi uzinzile, lungisa inani leekhonkco (ezinomlinganiselo ofanelekileyo wamanani) ukuqinisekisa uxinzelelo olufanelekileyo lwetsheyini. Ukuba inani leekhonkco kufuneka lihambelane ngokuchanekileyo nomgama ophakathi, lungisa indawo ye-sprocket okanye usebenzise i-tensioner ukunceda.
Ukuphathwa Okuguquguqukayo Kweemeko Ezikhethekileyo Zokusebenza
Kwiimeko ezingaqhelekanga (ezifana nokulungisa izixhobo ezindala okanye iinkqubo zothumelo ezingezizo ezisemgangathweni) apho ikhonkco lonxibelelwano elineenombolo ezingaqhelekanga lingenakuphepheka, khetha iikhonkco zotshintsho ezinamandla aphezulu (ezifana neepleyiti zentsimbi ze-alloy ezifakwe i-carburised) kwaye unciphise umthwalo olinganisiweyo ngama-20% ukuze unciphise amaxesha okulungisa.
Xa unxibelelana nabathengisi, kubalulekile ukuchaza ngokucacileyo iimeko zokusebenza kwezixhobo (isantya, umthwalo, ubushushu obungqongileyo, njl.njl.) kunye nenani elifunekayo leekhonkco zetyathanga. Abathengisi abakumgangatho ophezulu baya kucebisa isisombululo esifanelekileyo esisekelwe kwezi parameters, bephepha iingxaki zokusebenza ezibangelwa linani elingafanelekanga leekhonkco zetyathanga.
IV. Kutheni Abathengi Befanele Bayinike Ingqalelo Le Nkcazelo?
Kubathengi, inani leekhonkco zetsheyini lichaphazela ngokuthe ngqo ukuthembeka kwezixhobo kunye neendleko zizonke:
Iinkampani zemveliso zinokufumana ilahleko yamawaka eeyuan ngeyure ngenxa yokungasebenzi kakuhle okubangelwa kukwaphuka kwetsheyini.
Izixhobo zangaphandle ezifana noomatshini bezolimo abasebenzisa amakhonkco otshintsho zisengozini enkulu yokusilela kwiindawo ezinothuli nezifumileyo, nto leyo enyusa iindleko zokulungisa.
Abathengi bezixhobo zokuthumela ngaphandle kufuneka bathobele imigangatho yamazwe ngamazwe (efana ne-ISO 606 kunye ne-ANSI B29.1). Uninzi lwemigangatho yamazwe ngamazwe lucebisa ngokucacileyo ukuba amakhonkco anenani elifanayo lamakhonkco njengento ephambili, nto leyo enciphisa umngcipheko wokuthobela imithetho kurhwebo.
