Iimpawu zoLwakhiwo lweeTyathanga zeRoller eziNqamle kabini
Kwicandelo lokuhambisa nokuhambisa izinto kwimizi-mveliso, iirola ezirhuqwayo eziphindwe kabini, ngenxa yokukwazi ukuzivumelanisa nomgama omkhulu osembindini kunye nokulahlekelwa ngumthwalo okuncinci, ziye zaba zizinto eziphambili kwimishini yezolimo, ukuhambisa izinto kwimigodi, kunye nezixhobo zemizi-mveliso ezilula. Ngokungafaniyo neerola ezirhuqwayo eziqhelekileyo, uyilo lwazo olulodwa luchaza ngokuthe ngqo uzinzo kunye nokusebenza kwazo kwimigama emide. Eli nqaku liza kubonelela ngohlalutyo olunzulu lweempawu zesakhiwoiitsheyini zerola eziphindwe kabinikwiimbono ezintathu: uhlalutyo oluphambili lwesakhiwo, ingqiqo yoyilo, kunye nolwalamano lokusebenza, ukubonelela ngereferensi yobungcali yokukhetha, ukusetyenziswa, kunye nokugcinwa.
I. Uhlalutyo lwesakhiwo seCore Roller Chain Core
"I-double pitch" ye-double-pitch roller chain ibhekisa kumgama ophakathi kwe-chain link (umgama ukusuka embindini we-pin ukuya embindini we-pin esecaleni) ophindwe kabini kunowe-roller chain eqhelekileyo. Lo mahluko uphambili woyilo ukhokelela kuyilo olulodwa lwezi zinto zine ziphambili zesakhiwo, ezithi xa zidibene zincedise kwiingenelo zazo zokusebenza.
1. Iikhonkco zeChain: Iyunithi yokuqhuba ethi “Longer Pitch + Simplified Assembly”
Uyilo lwePitch: Ukusebenzisa ipitch ephindwe kabini kuneyeroller chain eqhelekileyo (umz., ipitch yechain eqhelekileyo eyi-12.7mm ihambelana nepitch yechain enepitch ephindwe kabini eyi-25.4mm). Oku kunciphisa inani lilonke leekhonkco zechain zobude obufanayo bokudlulisa, kunciphisa ubunzima bechain kunye nobunzima bokufakelwa.
Ukuhlanganiswa: Iyunithi yokuqhuba enye ine "iipleyiti ezimbini zangaphandle zokudibanisa + iipleyiti ezimbini zangaphakathi zokudibanisa + iseti enye yeebhushings ezijikelezayo," endaweni "yeseti enye yeepleyiti zokudibanisa ngepitch nganye" eqhelekileyo kwiityathanga zesiqhelo. Oku kwenza lula ukubalwa kwezixhobo ngelixa kuphucula uzinzo lokuthwala umthwalo ngepitch nganye.
2. Iirola kunye neeBushings: "Ilungele ukuNgqiniswa ngokuPheleleyo" kokunciphisa ukuDrag
Izinto zokuqengqeleka: Zenziwe kakhulu ngentsimbi ekhabhoni ephantsi (umz., intsimbi eyi-10#) ephathwa nge-carburizing kunye nokucima, ifikelela kubulukhuni bomphezulu be-HRC58-62 ukuqinisekisa ukumelana nokuguguleka xa ixutywa ne-sprocket. Intsimbi engatyiwayo okanye iiplastiki zobunjineli zingasetyenziselwa ukumelana nokugqwala kwezinye izicelo zomthwalo onzima. Uyilo lweSleeve: Isleeve kunye ne-roller zinokulingana okucacileyo (0.01-0.03mm), ngelixa umngxuma wangaphakathi kunye ne-pin zinokulingana okuphazamisekileyo. Oku kudala isakhiwo sokunciphisa ukurhuqa esineengqimba ezintathu: "ukulungiswa kwe-pin + ukujikeleza kwe-sleeve + ukuqengqeleka kwe-roller." Oku kunciphisa i-coefficient yokuxinana kokudluliselwa ukuya kwi-0.02-0.05, ephantsi kakhulu kune-sliding friction.
3. Iipleyiti zeTyayini: “Ububanzi obuBanzi + Izinto eziThintekileyo” zeNkxaso yokuThamba
Uyilo Lwangaphandle: Zombini iipleyiti zokudibanisa zangaphandle nezangaphakathi zisebenzisa isakhiwo "esibanzi esingunxande", esibanzi nge-15%-20% kuneetsheyini zesiqhelo zendlela efanayo. Oku kusabalalisa uxinzelelo lwe-radial ngexesha lokudibana kwe-sprocket kwaye kuthintela ukuguguleka kwimiphetho yepleyiti yokudibanisa.
Ukukhetha Ubukhulu: Ngokuxhomekeke kumlinganiselo womthwalo, ubukhulu bepleyiti yetsheyini buqhele ukuba yi-3-8mm (xa kuthelekiswa ne-2-5mm kwiitsheyini zesiqhelo). Zenziwe ngentsimbi yekhabhoni enamandla aphezulu (njenge-40MnB) ngokuyicima nokuyithambisa, iipleyiti zetsheyini zifikelela kumandla okutsalwa angama-800-1200 MPa, zihlangabezana neemfuno zomthwalo wokutsalwa kweetransmissions zexesha elide.
4. Iphini: Isitshixo soQhagamshelo "oluncinci + olude"
Uyilo lweDayamitha: Ngenxa yepitch ende, ububanzi bepitch buncinci kancinci kunobo bechain esemgangathweni eneenkcukacha ezifanayo (umz., ububanzi bechain pin eqhelekileyo yi-7.94mm, ngelixa ububanzi bechain pin yechain enepitch ephindwe kabini yi-6.35mm). Nangona kunjalo, ubude buphindwe kabini, okuqinisekisa unxibelelwano oluzinzileyo phakathi kwamakhonkco akufutshane nokuba ane-span enkulu.
Unyango Lomphezulu: Umphezulu wephini ugqunywe nge-chrome okanye nge-phosphate enobukhulu obuyi-5-10μm. Olu gqubuthelo luphucula ukumelana nokugqwala kwaye lunciphisa ukungqubana okutyibilikayo nomngxuma wangaphakathi wesingxobo, nto leyo eyandisa ubomi bokudinwa (ngokuvamile kufikelela kwiiyure ezili-1000-2000 zobomi bokudlulisa).
II. Unxibelelwano oluPhambili phakathi koYilo lweSakhiwo kunye nokuSebenza: Kutheni ikhonkco le-double-pitch lifanelekile kwiitransmissions ze-long-span?
Iimpawu zesakhiwo se-double-pitch roller chain zidlula nje ukukhulisa ubungakanani. Endaweni yoko, zijongana neemfuno eziphambili "zothumelo olude oluvela embindini ukuya embindini" kwaye zifezekisa iinjongo ezintathu eziphambili zokusebenza "zobunzima obuncitshisiweyo, ukutsala okuncitshisiweyo, kunye nomthwalo ozinzileyo." Ingqiqo ethile yonxibelelwano yile ilandelayo:
1. Uyilo lwepitch ende → Ubunzima betsheyini obuncitshisiweyo kunye neendleko zokufakela
Kumgama ofanayo wokudlulisa, ityathanga eliphindwe kabini linesiqingatha kuphela senani leekhonkco njengetyathanga eliqhelekileyo. Umzekelo, kumgama wokudlulisa wemitha ezili-10, ityathanga eliqhelekileyo (iphimbo le-12.7mm) lifuna iikhonkco ezingama-787, ngelixa ityathanga eliphindwe kabini (iphimbo le-25.4mm) lifuna iikhonkco ezingama-393 kuphela, nto leyo enciphisa ubunzima betyathanga lilonke malunga nama-40%.
Olu bunzima buncitshisiweyo lunciphisa ngokuthe ngqo "umthwalo ongaphezulu" wenkqubo yothumelo, ingakumbi kwiimeko zothumelo ezithe nkqo okanye ezithambekileyo (ezifana neelifti). Oku kunciphisa umthwalo wemoto kwaye kunciphisa ukusetyenziswa kwamandla (ukonga amandla okulinganiswe yi-8%-12%).
2. Iipleyiti zeTyayini eziBanzi + iiPini eziNamandla aphezulu → Uzinzo oluPhucukileyo lweSpan
Kwiitransmissions ezinde (umz., umgama osembindini odlula iimitha ezi-5), iitsheyini zinokwehla ngenxa yobunzima bazo. Iitsheyini ezibanzi ziyandisa indawo yoqhagamshelwano lwe-meshing nge-sprocket (ingaphezulu ngama-30% kuneetsheyini eziqhelekileyo), zinciphisa ukugeleza ngexesha lokudibana (ukugeleza kulawulwa ngaphakathi kwe-0.5mm).
Iiphini ezinde, zidityaniswe nokulingana kokuphazamiseka, zithintela amakhonkco eetyathanga ukuba angakhululeki ngexesha lokudluliselwa ngesantya esiphezulu (≤300 rpm), ziqinisekisa ukuchaneka kokudluliselwa (impazamo yokudluliselwa ≤0.1mm/mitha).
3. Ulwakhiwo Lokunciphisa Ukutsalwa KweeLayero Ezintathu → Ifanelekile kwiSantya Eziphantsi kunye Nobomi Obude
Iitsheyini ze-double-pitch zisetyenziswa kakhulu kwiitransmissions zesantya esiphantsi (ngesiqhelo ≤300 rpm, xa kuthelekiswa ne-1000 rpm kwiitsheyini zesiqhelo). Ulwakhiwo lwe-roller-bushing-pin olunezintlu ezintathu lusasaza ngokufanelekileyo ukungqubana okungashukumiyo kwisantya esiphantsi, luthintela ukuguguleka kwangaphambi kwexesha kwecandelo. Idatha yovavanyo lwasentsimini ibonisa ukuba kwimishini yezolimo (njengetsheyini yokuhambisa ye-combine harvester), iitsheyini ze-double-pitch zinokuba nobomi benkonzo obuphindwe kayi-1.5-2 kuneetsheyini zesiqhelo, nto leyo enciphisa ukugcinwa rhoqo.
III. Iimpawu zoLwakhiwo oluNgezelelweyo: Ukukhetha kunye noLondolozo Amanqaku aPhambili kwiiTyathanga zeRoller eziPhakathi
Ngokusekelwe kwiimpawu zesakhiwo ezingentla, ukukhethwa kunye nokugcinwa okujoliswe kuko kuyafuneka kwizicelo zokwenyani ukuze kwandiswe iingenelo zazo zokusebenza.
1. Ukhetho: Ukuhambelana kweeParamitha zoLwakhiwo ngokusekwe "kuMgama weZiko loThumelo + Uhlobo loMthwalo"
Kwimigama ephakathi engaphezulu kweemitha ezi-5, iintambo eziphindwe kabini ziyathandwa ukuze kuthintelwe ukufakwa okuntsonkothileyo kunye neengxaki zokuwa ezinxulumene neentambo eziqhelekileyo ngenxa yenani elikhulu leentambo.
Kwimithwalo ekhaphukhaphu (imithwalo engaphantsi kwe-500N), iipleyiti ezincinci zetsheyini (3-4mm) ezineeroli zeplastiki zingasetyenziselwa ukunciphisa iindleko. Kwimithwalo enzima (imithwalo engaphezulu kwe-1000N), iipleyiti ezinkulu zetsheyini (6-8mm) ezineeroli ezine-carburised ziyacetyiswa ukuqinisekisa amandla okutsalwa.
2. Ukugcinwa: Gxila "kwiindawo eziDibeneyo + uXinzelelo" ukuze kwandiswe ubomi.
Ukuthambisa rhoqo: Rhoqo emva kweeyure ezingama-50 zokusebenza, faka igrisi esekwe kwi-lithium (Uhlobo 2#) kwindawo ephakathi kwerola kunye ne-bushing ukuthintela ukuguguleka kwe-bushing okubangelwa kukungqubana okomileyo.
Uvavanyo loxinzelelo: Ngenxa yokuba ii-pitches ezinde zinokwandiswa, lungisa i-tensioner rhoqo emva kweeyure ezili-100 zokusebenza ukuze i-chain sag ihlale ngaphakathi kwe-1% yomgama ophakathi (umz., kumgama ophakathi weemitha ezili-10, sag ≤ 100mm) ukuthintela ukuqhekeka kwi-sprocket.
Isiphelo: Ulwakhiwo lumisela ixabiso. "Inzuzo ye-Long-Span" yee-Double-Pitch Roller Chains ivela kuYilo oluchanekileyo.
Iimpawu zesakhiwo see-double-pitch roller chains zijongana ngokuchanekileyo nemfuno "yothumelo olude-center-distance transmission" - ukunciphisa ubunzima nge-pitch ende, ukuphucula uzinzo ngee-wide link plates kunye nee-high-strength pin, kunye nokwandisa ubomi ngesakhiwo esinciphisa ukurhuqa esinee-layers ezintathu. Nokuba kukuthuthwa koomatshini bezolimo okanye uthumelo olukhawulezayo lwezixhobo zemigodi, ukuhambelana okunzulu koyilo lwesakhiwo kunye nokusebenza kwayo kwenza ukuba ibe yinxalenye yothumelo engenakutshintshwa kwicandelo lemizi-mveliso.
