Inqubo Yokukhiqiza I-Roller Chain engu-12B: Ukwembula I-Logic Yokukhiqiza Enembile Yezingxenye Zokudlulisa Zezimboni Eziyinhloko

Emkhakheni womhlaba wonke wokudlulisa nokuphatha izinto zezimboni, amaketanga e-roller angu-12B, anobubanzi bamandla awo abanzi, umthamo womthwalo ozinzile, kanye nokufakwa nokugcinwa okulula, abe yinto ebalulekile yokudlulisa imishini yezimayini, imishini yezolimo, kanye nezinhlelo zokuhambisa imigqa yokuhlanganisa. Ukuthembeka kwesikhathi eside kwamaketanga e-roller angu-12B ngaphansi komthwalo omkhulu, ukusebenza okuvama kakhulu kuncike enkambisweni yokukhiqiza eqinile neyinkimbinkimbi. Kusukela ekukhetheni izinto zokusetshenziswa kuya ekulethweni komkhiqizo oqediwe, ukulawula ngokucophelela kuzo zonke izigaba zenqubo kubalulekile ekunqumeni isikhathi sokuphila kweketanga, ukusebenza kahle kokudlulisa, kanye nokuqina kwengozi. Namuhla, sizohlola inqubo ephelele yokukhiqiza yamaketanga e-roller angu-12B, sichaze imininingwane yobuchwepheshe ngemuva kwalolu "ketanga olusezingeni eliphezulu."

1. Izisekelo Zenqubo: I-Standard Positioning kanye ne-Material Selection Logic ye-12B Roller Chain

Ngaphambi kokuhlola imininingwane yenqubo, kubalulekile ukucacisa kuqala "isilinganiso senqubo" seketanga le-roller le-12B. Njengoba iketanga lokudlulisa lihambisana ne-ANSI B29.1 (isilinganiso seketanga laseMelika) kanye ne-ISO 606 (isilinganiso seketanga lamazwe ngamazwe), ubukhulu balo obuyinhloko, njenge-pitch (19.05mm), ububanzi be-roller (11.91mm), kanye nobubanzi bengxenye yangaphakathi (12.57mm), kujwayelekile futhi kuzinzile. Umgomo oyinhloko wenqubo ukufeza ukusebenza okuphezulu ngezinto zokwakha kanye nobuchwepheshe bokucubungula ngenkathi kuhlangatshezwana nalezi zindinganiso.

1. Ukukhethwa Kokuhambisana Kwenqubo Kwezinto Eziyinhloko

Izingxenye ezahlukene ze-12B roller chain zidinga izinto ezihlukene kanye nezinqubo zangaphambi kokwelashwa ngenxa yezimo zazo zomthwalo ezihlukahlukayo:

Amaphini nama-roller: Njengezingxenye eziyinhloko ekudlulisweni kweketanga ezimelana nokushayisana, kukhethwa insimbi ethwala i-chromium enekhabhoni ephezulu ye-SUJ2 (elingana nensimbi yasekhaya ye-GCr15). Izinto kumele ziqale ziphathwe ngaphambi kokwelashwa “nge-spheroidizing annealing”—zifudumeze insimbi ibe ngu-780-820°C amahora angu-4-6, bese ziyipholisa kancane kancane ibe ngaphansi kuka-500°C. Le nqubo yehlisa ubulukhuni bezinto (ubulukhuni bukaBrinell ≤ 207 HB), ithuthukisa ukusebenza kahle kwemishini, futhi ibeka isisekelo sesakhiwo esincane esifanayo ngesikhathi sokwelashwa kokushisa okulandelayo, ivimbele ukuqhekeka ngesikhathi sokucinywa.

Amapuleti eketanga kanye nama-bushing: Amapuleti eketanga ayadingeka ukuze amelane nemithwalo yokudonswa, ngakho-ke kusetshenziswa insimbi yesakhiwo ye-ST52-3 low-carbon alloy (amandla okudonswa ≥ 520 MPa). Inqubo "yokucima nokulungisa" (ukucima okulandelwa ukufudumala okuphezulu) iletha ubulukhuni ku-HB220-250, okuqinisekisa kokubili amandla okudonswa kanye nezinga elithile lokuqina ukuvimbela ukuphuka. Ama-bushing enziwe ngensimbi ye-carburised engu-20CrMnTi, kanye nenqubo elandelayo ye-carburing yokwandisa ubulukhuni bomphezulu ukuze imelane nokushayisana okushelelayo ngamaphini.

II. Inqubo Yokukhiqiza Eyinhloko: Ukuguqulwa Okunembile Kusukela "Ezintweni Zokusetshenziswa" Kuya "Ezixhunyanisweni Zezinhlanganisela"

Ukukhiqizwa kwamaketanga e-roller angu-12B kuhilela izinqubo eziyisishiyagalombili eziyinhloko, ngayinye idinga ukulawulwa okuqinile kwamapharamitha enqubo ukuqinisekisa ukunemba nokusebenza:

1. Ukwelashwa Kwangaphambi Kwezinto Ezingavuthiwe: Ukuhlanza Indlela Yokucubungula

Ukususwa Kokugqwala Nokushiswa Kwamafutha: Lapho ingena eshabhu, yonke insimbi idluliselwa kuqala ngebhavu lokususa amafutha eline-alkaline (50-60°C, ifakwa emanzini imizuzu eyi-15-20) ukuze kususwe uwoyela ongaphezulu. Bese ifakwa ku-pickle nge-hydrochloric acid (15%-20% concentration, ifakwa emanzini okushisa kwegumbi imizuzu eyi-8-12) ukuze kususwe isikali. Ekugcineni, ihlanzwa ngamanzi ahlanzekile bese yomiswa ukuze kuvinjelwe ukungcola ukuthi kungathinti ukunemba kokucubungula okulandelayo.

Ukusika Ngokunembile: Kuye ngobukhulu bengxenye, ukusaha kwe-CNC noma ukusika nge-laser kusetshenziswa ukusika. Ukubekezelela ubude bokusika ngephini kumele kulawulwe ngaphakathi kuka-±0.1mm, kuyilapho ukusika kwe-chain plate kumele kugcine ukuphambuka kwesilinganiso se-aspect ratio okungu-≤0.05% ukuvimbela ukuguquka ngesikhathi sokunyathela okulandelayo.

2. Ukucubungula Ngokunembile Kwezingxenye Eziyinhloko: Ukunemba Okusezingeni Eliyimilimitha

Ukunyathela nokubhoboza ipuleti leketanga: Ukunyathela nokubhoboza ipuleti leketanga kwenziwa ku-CNC punch press kusetshenziswa "idayi eqhubekayo eqhubekayo." Uhlaka lwepuleti leketanga luqala ngokubhoboza, kulandelwe yizimbobo zephini kuzo zombili izinhlangothi. Ukubekezelelana kwezindawo zemigodi kumele kulawulwe ku-H7 (ububanzi bokubekezelelana 0-0.018mm), ngephutha lebanga eliphakathi kwembobo elingu-≤0.05mm ukuqinisekisa ukulingana okunembile okulandelayo nezipini. Ukususa i-burbor (ukusebenzisa isondo lokugaya noma ukugaya okudlidlizayo) kuyadingeka ngemuva kokunyathela ukuze kuvinjelwe imiphetho ebukhali ekulimazeni opharetha noma ekuphazamiseni ukuhlanganiswa. I-Roller Cold Forging: Insimbi ye-SUJ2 yakhiwa ngesinyathelo esisodwa kusetshenziswa umshini wokwakha obandayo oneziteshi eziningi. Intambo iqala ihlanganiswe, bese ikhishwa ibe yisimo se-roller, bese ekugcineni ibhobozwa (ukuze ifakwe esikhwameni). Ngesikhathi senqubo yokwakha obandayo, izinga lokushisa le-die (≤200°C) kanye nengcindezi (300-400 MPa) kumele kulawulwe ukuqinisekisa ukuthi iphutha lokuzungeza kwe-roller lingu-≤0.03mm ukuvimbela ukuguguleka okungavamile ngesikhathi sokusebenza.
Ukuqeda iphini: Iphini kuqala igaywa kusetshenziswa igrinder engenasisekelo (enobukhulu obungaphandle obungu-±0.05mm), bese igaywa kahle kuze kube yilapho ifinyelela ubukhulu bayo bokugcina (ukubekezelelana okungu-H8, 0-0.022mm) kusetshenziswa igrinder eyindilinga. Ubulukhuni bomphezulu obungu-Ra ≤0.8μm buyagcinwa. Lobu buso obubushelelezi bunciphisa ukungqubuzana okushelelayo nomkhono, kwandise impilo yalo yokusebenza.

3. Ukwelashwa Kokushisa: Ukunikeza "Ukusebenza Okuqinile" Ezingxenyeni
Ukushisa Amapuleti Eketanga: Ngemva kokunyathela, amapuleti eketanga afakwa esithandweni sokucima esiqhubekayo, esibanjwe ku-850-880°C imizuzu engama-30, bese ecinywa uwoyela. Bese efakwa esithandweni sokushisa ku-550-600°C amahora ama-2. Ubulukhuni bokugcina bufika ku-HB220-250, futhi amandla okucindezela akhushulwa abe yi-≥800 MPa, okuqinisekisa ukuthi angakwazi ukumelana nomthwalo wokucindezela olinganiselwe weketanga le-12B (≥18.8 kN). Ukucima i-Pin and Roller + Ukushisa Okuphansi: Amaphini nama-roller e-SUJ2 ashiswa abe yi-830-850°C (izinga lokushisa elibamba imizuzu engama-25) esithandweni sokucima i-mesh-belt, acinywe uwoyela, bese eqiniswa izinga lokushisa eliphansi ku-160-180°C amahora ama-2, afinyelele ubulukhuni bomphezulu be-HRC 58-62 kanye nobunzima obuyinhloko be-HRC 30-35. Lesi sakhiwo "sangaphandle esiqinile, sangaphakathi esiqinile" simelana nokuguguleka kanye nokuthinteka kwe-cushion, sivimbela ukuphuka. Ukushiswa Kwesikhafu Nokucinywa Kwesikhafu: Isikhafu esingu-20CrMnTi sifakwa esithandweni se-carburizing bese sishiswa ku-920-940°C amahora angu-4-6 nge-methanol kanye ne-propane (ama-carburizing agents) ukuze kufezwe okuqukethwe kwekhabhoni engaphezulu okungu-0.8%-1.2%. Isikhafu siyacinywa (kupholiswe uwoyela ngo-850°C) bese sishiswa ekushiseni okuphansi (180°C). Ubulukhuni bomphezulu obuvelayo yi-HRC 58-62, kanti ukujula kwengqimba ye-carburing kungu-0.8-1.2mm, okwandisa ngempumelelo impilo yokungqubuzana kwesikhafu ngokumelene nephini.

4. Ukuhlanganiswa Kwe-Modular: Ukuqinisekisa Ukuhlanganiswa Kwe-Overall Chain

Ukuhlanganiswa Kwesixhumanisi Sangaphakathi Nesangaphandle: Isixhumanisi sangaphakathi siqukethe i-sleeve, i-roller, kanye ne-inner link plate. Okokuqala, cindezela i-sleeve embobeni yephini ye-inner link plate (ukulingana kokuphazamiseka, amandla okucindezela ukulingana angu-5-8kN). Bese, slayida i-roller phezu kwe-sleeve (ukulingana kokuvula, ukulingana okungu-0.02-0.05mm). Isixhumanisi sangaphandle siqukethe i-pin kanye ne-outer link plate. Iphini icindezelwa embobeni ye-outer link plate (ukulingana kokuphazamiseka). Ngemva kokufakwa kwe-press, hlola ukuthi iqondile yini (ukuphambuka ≤ 0.5°) ukuze uvimbele ukubopha ngesikhathi sokusebenza.​
Ukuhlanganiswa Kweketanga Eligcwele Nokwelulwa Kwangaphambi Kokunwebeka: Izixhumanisi zangaphakathi nezangaphandle zihlanganiswa ndawonye ukuze kwakhiwe uchungechunge oluphelele. Lokhu kulandelwa “ukwelashwa kokunwetshwa kwangaphambi kokwelulwa”—amandla okunwetshwa angu-80% womthwalo olinganisiwe (cishe u-15kN) asetshenziswa emshinini wokuhlola ukunwetshwa ozinikele imizuzu engama-30. Lokhu kuqeda ukunwetshwa kokuqala kweketanga futhi kuvumela izingxenye ukuthi zivumelane kakhulu ndawonye. Lokhu kuvumela ukuthi ukunwetshwa okulandelayo kulawulwe ngaphakathi kuka-0.5% (uma kuqhathaniswa nesilinganiso semboni esingu-1%-1.5%).

III. Inqubo Yokulawula Ikhwalithi: Ukuhlolwa Kwenqubo Egcwele Ukuze Kususwe Imikhiqizo Engaphansi Kwezinga Elifanele

Amaketanga e-roller angu-12B okuthunyelwa kwamanye amazwe ahlolwa ngezindlela eziningi ukuqinisekisa ukuhambisana nezindinganiso zomhlaba wonke. Izinyathelo zokuhlola eziyinhloko zifaka:

1. Ukuhlolwa Kokunemba Okulinganayo

Umshini wokulinganisa onama-three-dimensional coordinate (CMM) usetshenziselwa ukuhlola ubukhulu obubalulekile njengebanga eliphakathi lembobo ye-chainplate, ububanzi bangaphandle be-pin shaft, kanye nobubanzi be-roller. Kwenziwa isampula engahleliwe yezingcezu ezingu-20 ngebhetshi ngayinye, ngesilinganiso sokudlula esingu-100%.

Kusetshenziswa i-pitch gauge ukuhlola i-chain pitch. Ukuphambuka kwe-pitch ngemitha kumele kube ngu-≤0.3mm ukuqinisekisa ukuthi i-sprocket ine-mesh enembile.

2. Ukuhlolwa Kwezakhiwo Zemishini
Ukuhlolwa Kwamandla Okuthamba: Iketanga licindezelwa emshinini wokuhlola ukuthamba lize liphuke. Umthwalo wokuphuka kumele ube ngaphezulu kuka-28.2kN (udlule kakhulu umthwalo olinganiselwe ongu-18.8kN) ukuqinisekisa ukuphepha uma kwenzeka ukugcwala ngokweqile.
Ukuhlolwa Kokuphila Kokukhathala: Iketanga lifakwe “emshinini wokuhlola ukukhathala kweketanga” futhi lifakwa ku-50% womthwalo olinganisiwe (cishe u-9.4kN) ngesivinini esingu-1500r/min. Isikhathi sokukhathala kumele sibe ngamahora angu-≥ angu-500 (izinga lomkhakha lingamahora angu-300), okulingisa ukuthembeka ngaphansi kwezimo zomthwalo ophezulu wesikhathi eside.

3. Ukuhlolwa Kwekhwalithi Yomphezulu

Sebenzisa isihloli sobulukhuni bomphezulu ukuhlola izindawo zephini kanye ne-roller; inani le-Ra kumele libe ngu-≤0.8μm.

Hlola ukwelashwa kwendawo (isb., ukugaya, ukwenza kube mnyama): ubukhulu besendlalelo sokugaya kumele bube ≥8μm futhi akumele bubonise ukugqwala ngemva kokuhlolwa kokufuthwa kukasawoti kwamahora angu-48 (isifutho sikasawoti esingathathi hlangothi, isisombululo se-NaCl esingu-5%). Ukwelashwa kokwenza kube mnyama kumele kube okufanayo futhi kungabi namabala, futhi ukunamathela kumele kuhlangabezane nezinga le-GB/T 10125.

IV. Inani Lobuciko: Kungani ubuciko bekhwalithi ephezulu buthuthukisa ukuncintisana emakethe kwamaketanga e-roller angu-12B?

Izinzuzo zobuchwepheshe ze-12B roller chain zihumushela ngqo enzuzweni:

Isikhathi eside sokuphila: Sisebenzisa izinto ze-SUJ2 kanye nokwelashwa kokushisa okunembile, iketanga liziqhayisa ngokuphila kwenkonzo okumaphakathi kwamahora angu-8,000-10,000, isikhathi esingaphezu kuka-40% kuneketanga elivamile (amahora angu-5,000-6,000), kunciphisa izindleko zokufaka esikhundleni kanye nesikhathi sokungasebenzi.

Ukudluliselwa okuzinzile: Ukunemba kobukhulu bezinga le-millimeter kanye nokunwebeka ngaphambi kokusebenzisa kuqinisekisa ukugijima kweketanga okungu-≤0.1mm ngesikhathi sokusebenza, kugcina ukusebenza kahle kokudluliselwa kungaphezu kuka-98%, okwenza kufaneleke ukusetshenziswa kwesivinini esikhulu njengemishini yendwangu kanye nemigqa yokuhlanganisa ezenzakalelayo.

Kuguquguquka kakhulu: Ukwelashwa kwendawo okukhethwa kukho (ukwenza i-galvanizing, ukwenza kube mnyama, kanye ne-phosphating) kanye nezixazululo zokwelapha ukushisa ezenziwe ngokwezifiso (njengokushisa okuphansi kwezinga lokushisa ezindaweni eziphansi kwezinga lokushisa) kuhlangabezana nezidingo zokusebenza ezahlukahlukene. Isibonelo, izintambo ezihlanganisiwe zingasetshenziswa ezitshalweni zokucubungula ukudla ukuvimbela ukugqwala, kanti izintambo ezihlanganisiwe zingasetshenziswa emishinini yokumba ukuze kuvinjwe uthuli kanye nokumelana nokuguguleka.

Isiphetho: Ubuciko “buyinzuzo yokuncintisana efihliwe” yamaketanga e-12B Roller

Emakethe yomhlaba wonke ye-12B roller chain, "intengo ephansi" ayiseyona inzuzo eyinhloko. Esikhundleni salokho, "ukunemba kwenqubo" kanye "nokuqina kokusebenza" kuyisihluthulelo sokuthola ukwethenjwa kwamakhasimende aphesheya kwezilwandle. Kusukela ezindinganisweni eziqinile ekukhetheni izinto zokusetshenziswa, kuya ekulawulweni kwezinga lamamilimitha enkambisweni yokukhiqiza, kuya ekuhlolweni okuphelele kwangaphambi kokuthunyelwa, yonke inqubo inesibopho sokuthembeka komkhiqizo.
