Izici Zesakhiwo Sezintambo Ezijikelezayo Eziphindwe Kabili
Emkhakheni wokudlulisa nokuhambisa izimboni, amaketanga e-roller ane-pitch double, ngenxa yokuzivumelanisa kwawo nebanga elikhulu eliphakathi nendawo kanye nokulahlekelwa umthwalo ophansi, abe yizingxenye ezibalulekile emishinini yezolimo, ekuthuthweni kwezimayini, kanye nasemishinini yezimboni elula. Ngokungafani namaketanga e-roller avamile, ukwakheka kwawo okuyingqayizivele kunquma ngqo ukuzinza kwawo kanye nokusebenza kahle kwawo ebangeni elide. Lesi sihloko sizohlinzeka ngokuhlaziywa okujulile kwezici zesakhiwo seamaketanga e-roller ane-pitch ephindwe kabilikusukela emibonweni emithathu: ukuhlaziywa kwesakhiwo okuyinhloko, ukuqonda komklamo, kanye nokuhambisana kokusebenza, okunikeza ireferensi yobungcweti yokukhetha, ukusetshenziswa, kanye nokugcinwa.
I. Ukuhlaziywa Kwesakhiwo Se-Double-Pitch Roller Chain Core
“I-double pitch” ye-double-pitch roller chain ibhekisela ebangeni eliphakathi le-chain link (ibanga elisuka enkabeni ye-pin liye enkabeni ye-pin eseduze) eliphindwe kabili kune-roller chain evamile. Lo mehluko oyisisekelo womklamo uholela ekwakhiweni okuyingqayizivele kwezingxenye ezine ezilandelayo zesakhiwo, ezihlanganisa ndawonye izinzuzo zayo zokusebenza.
1. Izixhumanisi Zezinkinobho: Iyunithi Yokushayela “Ende Ye-Pitch + Elula”
Umklamo Wephimbo: Ukusebenzisa ipimbo eliphindwe kabili kuneliketanga elijwayelekile le-roller (isb., ipimbo elijwayelekile le-chain elingu-12.7mm lihambisana nepimbo le-chain eliphindwe kabili elingu-25.4mm). Lokhu kunciphisa inani eliphelele lezixhumanisi zephethini zobude obufanayo bokudlulisa, kunciphisa isisindo sephethini kanye nobunzima bokufakwa.
Ukuhlanganiswa: Iyunithi yokushayela eyodwa iqukethe “amapuleti amabili ezixhumanisi zangaphandle + amapuleti amabili ezixhumanisi zangaphakathi + isethi eyodwa yama-roller bushings,” kunokuba kube “isethi eyodwa yamapuleti ezixhumanisi ngephimbo ngalinye” evamile yamaketanga avamile. Lokhu kwenza kube lula ukubalwa kwezingxenye ngenkathi kuthuthukiswa ukuzinza kokuthwala umthwalo ngephimbo ngalinye.
2. Ama-Roller nama-Bushing: “Ukulingana Okunembe Kakhulu” Kokunciphisa Ukudonswa
Izinto Zokugoqa: Zenziwe kakhulu ngensimbi ephansi yekhabhoni (isb., insimbi engu-10#) ephathwa nge-carburizing kanye ne-quenching, ifinyelela ubulukhuni bomphezulu be-HRC58-62 ukuqinisekisa ukumelana nokuguguleka lapho ihlanganiswa ne-sprocket. Insimbi engagqwali noma ipulasitiki yobunjiniyela ingasetshenziswa ukumelana nokugqwala kwezinye izinhlelo zokusebenza ezisindayo. Umklamo Wesikhwama: Isikhwama kanye ne-roller zinokulingana kwesikhala (0.01-0.03mm), kuyilapho imbobo yangaphakathi nephini zinokulingana kokuphazamiseka. Lokhu kudala isakhiwo sokunciphisa ukuhudula esinezingqimba ezintathu: "ukulungiswa kwephini + ukujikeleza kwesikhwama + ukugoqa kwe-roller." Lokhu kunciphisa i-coefficient yokugoqa kokudlulisela ibe ngu-0.02-0.05, ephansi kakhulu kunokugoqa okushelelayo.
3. Amapuleti Eketanga: “Ububanzi Obubanzi + Izinto Ezijiyile” Zokusekela Ukunamathela
Umklamo Wangaphandle: Amapuleti okuxhumanisa angaphandle nangaphakathi asebenzisa isakhiwo "esibanzi esingunxande", esibanzi ngo-15%-20% kunezintambo ezivamile zencazelo efanayo. Lokhu kusabalalisa ingcindezi ye-radial ngesikhathi sokuhlangana kwe-sprocket futhi kuvimbela ukuguguleka emaphethelweni epuleti lochungechunge.
Ukukhetha Ubukhulu: Kuye ngesilinganiso somthwalo, ubukhulu bepuleti leketanga buvame ukuba ngu-3-8mm (uma kuqhathaniswa no-2-5mm weketanga elivamile). Enziwe ngensimbi yekhabhoni enamandla aphezulu (njenge-40MnB) ngokucisha nokushisa, amapuleti eketanga athola amandla okudonsa angu-800-1200 MPa, okuhlangabezana nezidingo zomthwalo wokudonsa wama-transmissions esikhathi eside.
4. Iphinikhodi: Isihluthulelo Sokuxhuma “Ububanzi Obuncane + Isigaba Eside”
Umklamo Wobubanzi: Ngenxa yephimbo elide, ububanzi bephini buncane kancane kunobochungechunge olujwayelekile olunencazelo efanayo (isb., ububanzi bephini lochungechunge olujwayelekile bungu-7.94mm, kuyilapho ububanzi bephini lochungechunge oluphindwe kabili bungu-6.35mm). Kodwa-ke, ubude buphindwe kabili, okuqinisekisa ukuxhumana okuzinzile phakathi kwezixhumanisi eziseduze ngisho nangezikhala ezinkulu.
Ukwelashwa Komphezulu: Umphezulu wephini ufakwe i-chrome noma i-phosphate enobukhulu obungu-5-10μm. Lokhu kuhlanganiswa kuthuthukisa ukumelana nokugqwala futhi kunciphisa ukungqubuzana okushelelayo nembobo yangaphakathi yesikhafu, okwandisa impilo yokukhathala (ngokuvamile kufinyelela emahoreni ayi-1000-2000 okuphila kokudlulisela).
II. Ukuxhumana Okuyinhloko Phakathi Komklamo Wesakhiwo Nokusebenza: Kungani uchungechunge lwe-double-pitch lufanelekela ukudluliselwa kwe-long-span?
Izici zesakhiwo seketanga le-roller eline-pitch double zidlula nje ukukhulisa usayizi. Esikhundleni salokho, zibhekana nesidingo esiyinhloko "sokudlulisa okude phakathi nendawo kuya enkabeni" futhi zifeze imigomo emithathu yokusebenza ebalulekile "yesisindo esincishisiwe, ukuhudula okuncishisiwe, kanye nomthwalo ozinzile." I-logic yokuxhumanisa ethize ilandelayo:
1. Umklamo wephimbo elide → Isisindo seketanga esincishisiwe kanye nezindleko zokufaka
Ngebanga elifanayo lokudlulisa, uchungechunge olunezingqimba ezimbili lunengxenye kuphela yenani lezixhumanisi njengeketanga elivamile. Isibonelo, ngebanga lokudlulisa elingamamitha ayi-10, uchungechunge oluvamile (iphimbo elingu-12.7mm) ludinga izixhumanisi ezingu-787, kuyilapho uchungechunge olunezingqimba ezimbili (iphimbo elingu-25.4mm) ludinga izixhumanisi ezingu-393 kuphela, okunciphisa isisindo seketanga cishe ngo-40%.
Lesi sisindo esincishisiwe sinciphisa ngqo "umthwalo ongaphezulu" wesistimu yokudlulisa, ikakhulukazi ezimweni zokudlulisa eziqondile noma ezithambekele (njengezilifti). Lokhu kunciphisa umthwalo wenjini futhi kunciphisa ukusetshenziswa kwamandla (ukonga kwamandla okulinganisiwe okungu-8%-12%).
2. Ama-Chainplates Amabanzi + Amaphini Anamandla Aphezulu → Ukuzinza Okuthuthukisiwe Kwesikhala
Kuma-transmissions amade (isb., amabanga aphakathi adlula amamitha ama-5), amaketanga avame ukugoba ngenxa yesisindo sawo. Ama-chainplate abanzi andisa indawo yokuxhumana ene-sprocket (30% mkhulu kune-chain evamile), kunciphisa ukugeleza ngesikhathi sokuzibandakanya (ukugeleza kulawulwa ngaphakathi kuka-0.5mm).
Amaphini amade, ahlanganiswe nokulingana kokuphazamiseka, avimbela izixhumanisi zeketanga ukuthi zingakhululeki ngesikhathi sokudlulisa ngesivinini esikhulu (≤300 rpm), okuqinisekisa ukunemba kokudlulisa (iphutha lokudlulisa ≤0.1mm/imitha).
3. Isakhiwo Sokunciphisa Ukuhudula Esinezingqimba Ezintathu → Sifanele Isivinini Esiphansi Nempilo Ende
Amaketanga amabili asetshenziswa kakhulu kuma-transmission anesivinini esiphansi (ngokuvamile ≤300 rpm, uma kuqhathaniswa ne-1000 rpm yamaketanga avamile). Isakhiwo se-roller-bushing-pin esinezingqimba ezintathu sisabalalisa ngempumelelo ukungqubuzana okungaguquki ngesivinini esiphansi, sivimbele ukuguguleka kwezingxenye ngaphambi kwesikhathi. Idatha yokuhlola yasensimini ikhombisa ukuthi emishinini yezolimo (njengeketanga lokuhambisa lomshini wokuvuna ohlanganisiwe), amaketanga amabili angasetshenziswa isikhathi esiphindwe ka-1.5-2 kuneketanga elivamile, okunciphisa imvamisa yokulungisa.
III. Izici Ezinwetshiwe Zesakhiwo: Ukukhetha Nokunakekela Amaphuzu Ayisihluthulelo Ezintambo Ezinama-Double-Pitch Roller
Ngokusekelwe ezicini zesakhiwo ezingenhla, ukukhethwa nokugcinwa okuqondiwe kuyadingeka ezinhlelweni zangempela ukuze kwandiswe izinzuzo zazo zokusebenza.
1. Ukukhetha: Ukufanisa Amapharamitha Esakhiwo Ngokusekelwe “Kubanga Lesikhungo Sokudlulisa + Uhlobo Lomthwalo”
Emabangeni aphakathi angaphezu kwamamitha ama-5, amaketanga aphindwe kabili ayathandwa ukuze kugwenywe ukufakwa okuyinkimbinkimbi nezinkinga zokuwa ezihambisana namaketanga avamile ngenxa yenani elikhulu lezixhumanisi.
Ukuze kuthuthwe umthwalo olula (imithwalo engaphansi kuka-500N), amapuleti eketanga amancane (3-4mm) anama-rollers epulasitiki angasetshenziswa ukunciphisa izindleko. Ukuze kuthuthwe umthwalo osindayo (imithwalo engaphezu kuka-1000N), amapuleti eketanga amakhulu (6-8mm) anama-rollers ane-carburised ayanconywa ukuqinisekisa amandla okudonsa.
2. Ukulungisa: Gxila “Ezindaweni Ezingqubuzanayo + Ukucindezeleka” Ukuze Uphile Kahle.
Ukugcoba Okuvamile: Njalo emahoreni angu-50 okusebenza, faka igrisi esekelwe ku-lithium (Uhlobo 2#) esikhaleni esiphakathi kwe-roller kanye ne-bushing ukuze uvimbele ukuguguleka kwe-bushing okubangelwa ukungqubuzana okomile.
Ukuhlolwa Kokucindezeleka: Ngenxa yokuthi ama-pitch amade avame ukunwebeka, lungisa i-tensioner njalo emahoreni ayi-100 okusebenza ukuze ugcine uchungechunge lugobile ngaphakathi kwe-1% yebanga eliphakathi nendawo (isb., ebangeni eliphakathi elingamamitha ayi-10, gobile ≤ 100mm) ukuvimbela ukuqhekeka kusuka ku-sprocket.
Isiphetho: Isakhiwo Sinquma Inani. “Inzuzo Ende” Yamaketanga E-Double-Pitch Roller Ivela Kumklamo Oqondile.
Izici zesakhiwo samaketanga okujikijela amabili aphindwe kabili zibhekana ngqo nesidingo "sokudlulisa ibanga elide phakathi nendawo" - ukunciphisa isisindo esibi ngephimbo elide, ukuthuthukisa ukuzinza ngamapuleti ezixhumanisi ezibanzi namaphini anamandla aphezulu, nokwandisa impilo ngesakhiwo sokunciphisa ukudonsa esinezingqimba ezintathu. Kungakhathaliseki ukuthi ukuthuthwa kwemishini yezolimo ibanga elide noma ukudlulisa imishini yezimayini ngesivinini esiphansi, ukuhambisana okujulile komklamo wayo wesakhiwo nokusebenza kwayo kwenza kube yingxenye yokudlulisa engenakuphindwa emkhakheni wezimboni.
