Ubudlelwano Phakathi Kokukhethwa Kwe-Roller Chain Pitch kanye Nesivinini

Ubudlelwano Phakathi Kokukhethwa Kwe-Roller Chain Pitch kanye Nesivinini

Ezinhlelweni zokudlulisa izimboni, iphimbo le-roller chain kanye nesivinini kuyizinto ezibalulekile ezinquma ukusebenza kahle kokudlulisa, isikhathi sokuphila kwemishini, kanye nokuzinza kokusebenza. Onjiniyela abaningi kanye nabasebenzi bokuthenga, abagxile kakhulu emandleni okuthwala umthwalo ngesikhathi sokukhetha, bavame ukunganaki ukufana kwalezi zici ezimbili. Lokhu ekugcineni kuholela ekugugeni nasekuphukeni kwe-chain ngaphambi kwesikhathi, ngisho nesikhathi sokungasebenzi komugqa wokukhiqiza. Lesi sihloko sizochaza izimiso eziyisisekelo kanye nobudlelwano obukhona phakathi kwephimbo nesivinini, sinikeze izindlela zokukhetha ezisebenzayo ukukusiza ukhethe i-roller chain efanele kakhulu yezimo zokusebenza ezahlukene.

I. Ukuqonda Imiqondo Emibili Eyinhloko: Incazelo kanye Nokubaluleka Kwezimboni Kokuzwakala Kwezwi Nejubane

Ngaphambi kokuhlaziya ubudlelwano phakathi kwalaba ababili, kubalulekile ukucacisa izincazelo eziyisisekelo—lokhu kubalulekile ukuze kugwenywe amaphutha okukhetha. Kungakhathaliseki ukuthi kusetshenziswa amaketanga okugoqa e-ANSI (American Standard), ISO (International Standard), noma GB (National Standard), umthelela oyinhloko wephimbo nesivinini uhlala ufana.

1. Iphimbo Le-Roller Chain: Linquma “Umthamo Womthwalo” kanye “Nokushelela Kokusebenza”

Iphimbo liyisici esiyinhloko seketanga lama-roller, libhekisela ebangeni eliphakathi kwezikhungo zama-roller amabili aseduze (elikhonjiswa uphawu "p" futhi ngokuvamile lilinganiswa ngama-mm noma ama-intshi). Linquma ngqo izici ezimbili ezibalulekile zamaketanga:

Umthamo Womthwalo: Iphimbo elikhulu ngokuvamile liholela ezingxenyeni ezinkulu zeketanga njengamapuleti namaphini, kanye nomthwalo olinganiswe kakhulu (womabili ongaguquki noguquguqukayo) ongathwalwa, okwenza ufanelekele ukusetshenziswa okunzima (njengemishini yezimayini kanye nemishini yokuthutha esindayo).

Ukushelela Kokusebenza: Iphimbo elincane linciphisa "imvamisa yomthelela" lapho iketanga lihlangana ne-sprocket, okuholela ekudlidlizeni okuncane nomsindo ngesikhathi sokudlulisa. Lokhu kuyenza ifaneleke kakhulu ezinhlelweni zokusebenza ezidinga ukuzinza okuphezulu (njengamathuluzi omshini onembile kanye nemishini yokupakisha ukudla).

2. Ijubane Lokujikeleza: Linquma “Ukucindezeleka Okunamandla” kanye “Nezinga Lokuguguleka”

Ijubane lokujikeleza lapha libhekisela ngqo esivinini se-sprocket yokushayela lapho iketanga lixhunywe khona (elikhonjiswa uphawu "n" futhi ngokuvamile lilinganiswa ngo-r/min), hhayi isivinini sesiphelo esiqhutshwayo. Umthelela walo kuketanga ubonakala kakhulu ezicini ezimbili:
Ukucindezeleka okunamandla: Uma isivinini siphezulu, kulapho amandla e-centrifugal akhiqizwa uchungechunge ngesikhathi sokusebenza eba makhulu khona. Lokhu kwandisa kakhulu "umthwalo womthelela" lapho uchungechunge luxhumanisa i-mesh namazinyo e-sprocket (okufana nokushaya kwemoto edlula i-speed bump ngesivinini esikhulu).
Izinga lokuguguleka: Uma isivinini siphezulu, kulapho ama-chain meshes amaningi ane-sprocket kanye nokujikeleza okuhlobene kwama-rollers nama-pin kukhuphuka khona. Inani eliphelele lokuguguleka esikhathini esifanayo liyanda ngokulinganayo, okunciphisa ngqo impilo yesevisi ye-chain.

II. I-Core Logic: Isimiso "Sokufaniswa Okuphambene" Sokuphakama Nesivinini

Umkhuba omkhulu wezimboni uqinisekisile ukuthi iphimbo le-roller chain kanye nesivinini kunobudlelwano obucacile "bokufaniswa okuphambene"—okungukuthi, uma ijubane liphakeme, iphimbo kufanele libe lincane, kuyilapho ijubane liphansi, iphimbo lingaba likhulu. Ingqikithi yalesi simiso ukulinganisela "izidingo zomthwalo" "nengozi yokucindezeleka enamandla." Lokhu kungahlukaniswa kube yizigaba ezintathu:

1. Ukusebenza ngesivinini esikhulu (ngokuvamile i-n > 1500 r/min): Iphimbo elincane libalulekile.
Uma ijubane le-drive sprocket lidlula u-1500 r/min (njengakumafeni nama-motor drive amancane), ukucindezeleka okuguquguqukayo kanye namandla e-centrifugal ku-chain kuyanda kakhulu. Ukusebenzisa i-large-pitch chain kulesi simo kungaholela ezinkingeni ezimbili ezibalulekile:

Umthwalo osindayo: Amaketanga amakhulu anezixhumanisi ezinkulu, okuholela endaweni enkulu yokuxhumana kanye namandla okuthintana namazinyo e-sprocket ngesikhathi sokuhlanganisa i-mesh. Lokhu kungabangela kalula "ukugxuma kwesixhumanisi" noma "ukuphuka kwamazinyo e-sprocket" ngesivinini esikhulu.

Ukuxega okubangelwa amandla e-Centrifugal: Amaketanga amakhulu anesisindo esikhulu, kanti amandla e-centrifugal akhiqizwa ngesivinini esikhulu angabangela ukuthi iketanga liphume emazinyweni e-sprocket, okubangela “ukuwa kweketanga” noma “ukushelela kwedrayivu.” Ezimweni ezimbi kakhulu, lokhu kungaholela ekushayweni kwemishini. Ngakho-ke, ekusetshenzisweni kwesivinini esikhulu, amaketanga ane-pitch engu-12.7mm (1/2 intshi) noma ngaphansi ngokuvamile akhethwa, njengochungechunge lwe-ANSI #40 nolwe-#50, noma uchungechunge lwe-ISO 08B nolwe-10B.

2. Izinhlelo zokusebenza zesivinini esimaphakathi (ngokuvamile ama-r/min angu-500 < n ≤ 1500 r/min): Khetha iphimbo elimaphakathi.
Ukusetshenziswa kwesivinini esimaphakathi kuvame kakhulu ezisetshenziswa ezimbonini (njengezithuthi, izinti zamathuluzi omshini, kanye nemishini yezolimo). Ibhalansi phakathi kwezidingo zomthwalo kanye nezidingo zokushelela kubalulekile.
Kumithwalo emaphakathi (njengezithuthi ezilula ezinamandla alinganiselwe angu-10kW noma ngaphansi), amaketanga ane-pitch engu-12.7mm kuya ku-19.05mm (1/2 intshi kuya ku-3/4 intshi) ayanconywa, njenge-ANSI #60 kanye nochungechunge lwe-#80. Kumithwalo ephezulu (njengemishini yomshini ephakathi nendawo enamandla alinganiselwe angu-10kW-20kW), iketanga eline-pitch engu-19.05mm-25.4mm (3/4-intshi kuya ku-1-intshi), njenge-ANSI #100 kanye nochungechunge lwe-#120, lingakhethwa. Kodwa-ke, ukuqinisekiswa okwengeziwe kobubanzi bezinyo le-sprocket kuyadingeka ukuvimbela ukungazinzi kwe-meshing.

3. Ukusebenza ngesivinini esiphansi (ngokuvamile i-n ≤ 500 r/min): Iketanga elikhulu lokuphonsa lingakhethwa.

Ezimweni zesivinini esiphansi (njengemishini yokumba kanye nama-hoist asebenza kanzima), ukucindezeleka okuguquguqukayo kweketanga kanye namandla e-centrifugal kuphansi kakhulu. Umthamo wokuthwala umthwalo uba yisidingo esiyinhloko, futhi izinzuzo zeketanga elikhulu zingasetshenziswa ngokugcwele:
Amaketanga amakhulu anikeza amandla amakhulu ezingxenye futhi angamelana nemithwalo yokushaywa yamakhulu e-kN, okuvimbela ukuphuka kwepuleti leketanga nokugoba kwephini ngaphansi kwemithwalo esindayo.
Izinga lokuguguleka liphansi ngesivinini esiphansi, okuvumela amaketanga amakhulu ukuthi alondoloze isikhathi sokuphila esifanelana nesikhathi sokuphila semishini iyonke, okususa isidingo sokushintshwa njalo (ngokuvamile iminyaka emi-2-3). Amaketanga ane-pitch ≥ 25.4mm (1 intshi), njenge-ANSI #140 kanye ne-#160 series, noma amaketanga amakhulu aklanyelwe wena, asebenza kanzima, avame ukusetshenziswa kulesi simo.

III. Umhlahlandlela Owusizo: Qondanisa Ngokunembile Iphimbo Nesivinini Ngezinyathelo Ezi-4

Ngemva kokuqonda le mbono, sekuyisikhathi sokuyisebenzisa ngezinqubo ezijwayelekile. Izinyathelo ezine ezilandelayo zizokusiza ukuthi ukhethe ngokushesha uchungechunge olufanele futhi ugweme amaphutha abangelwa ukuthembela kokuhlangenwe nakho:

Isinyathelo 1: Thola Amapharamitha Ayinhloko – Qoqa Idatha Engukhiye Emi-3 Kuqala

Ngaphambi kokukhetha uchungechunge, kufanele uthole lawa mapharamitha amathathu ayinhloko emishini; akukho neyodwa yawo engashiywa:

Isivinini se-sprocket yokushayela (n): Thola lokhu ngqo kusuka ku-motor noma ku-drive end manual. Uma isivinini se-drive end kuphela esitholakalayo, bala ngokubuyela emuva usebenzisa ifomula ethi “Isilinganiso sokudlulisa = inani lamazinyo ku-sprocket yokushayela / inani lamazinyo ku-sprocket eqhutshwayo.”

Amandla okudlulisa alinganisiwe (P): Lawa amandla (ku-kW) adingekayo ukuze adluliselwe yimishini ngesikhathi sokusebenza okuvamile. Lokhu kufaka phakathi imithwalo ephezulu (njengemithwalo yokushaqeka ngesikhathi sokuqalisa, evame ukubalwa njengezikhathi eziyi-1.2-1.5 zamandla alinganisiwe).
Indawo yokusebenza: Hlola uthuli, uwoyela, amazinga okushisa aphezulu (>80°C), noma amagesi agqwalisayo. Ezindaweni ezinzima, khetha amaketanga anemigoqo yokugcoba kanye nezingubo zokulwa nokugqwala. Iphimbo kufanele likhuliswe ngo-10%-20% ukuze livumele ukuguguleka.

Isinyathelo 2: Ukukhetha Ububanzi Bokuphakanyiswa Kwangaphambili Ngokusekelwe Esivinini
Bheka ithebula elingezansi ukuze uthole ububanzi bephimbo lokuqala ngokusekelwe kwisivinini se-drive sprocket (usebenzisa uchungechunge olujwayelekile lwe-ANSI njengesibonelo; ezinye izindinganiso zingaguqulwa ngokufanele):
Isivinini se-Drive Sprocket ​​(r/min) Ububanzi Bokuphakanyiswa Okunconyiwe (mm) Uchungechunge Lwe-ANSI Chain Oluhambisanayo Izicelo Ezijwayelekile
>1500 6.35-12.7 #25, #35, #40 Amafeni, Ama-Small Motors
500-1500 12.7-25.4 #50, #60, #80, #100 Ama-Conveyor, Amathuluzi Omshini
<500 25.4-50.8 #120, #140, #160 Isikhiphi, I-Lifti

Isinyathelo 3: Qinisekisa ukuthi i-Pitch ihlangabezana nomthamo womthwalo usebenzisa amandla
Ngemva kokukhetha iphimbo lokuqala, qinisekisa ukuthi iketanga lingamelana namandla alinganisiwe usebenzisa i-“Power Calculation Formula” ukuze ugweme ukwehluleka kokulayisha ngokweqile. Uma uthatha iketanga elijwayelekile le-ISO njengesibonelo, ifomula elula imi kanje:
Ukudluliswa kwamandla okuvunyelwe yi-Chain (P₀) = K₁ × K₂ × Pₙ
Kuphi: I-K₁ iyisici sokulungisa isivinini (isivinini esiphezulu siphumela ku-K₁ ephansi, engatholakala kukhathalogi yochungechunge); I-K₂ iyisici sokulungisa isimo sokusebenza (0.7-0.9 ezindaweni ezinzima, 1.0-1.2 ezindaweni ezihlanzekile); kanye ne-Pₙ ​​ngamandla alinganiswe ochungechunge (angatholakala ngephimbo kukhathalogi yomkhiqizi).
Isimo sokuqinisekisa: I-P₀ kumele ihlangabezane no-≥ 1.2 × P (i-1.2 iyisici sokuphepha, esingandiswa sibe yi-1.5 ezimweni ezinzima).

Isinyathelo 4: Lungisa uhlelo lokugcina ngokusekelwe endaweni yokufaka.
Uma iphimbo elikhethiwe ekuqaleni lilinganiselwe yisikhala sokufaka (isb., isikhala sangaphakathi semishini sincane kakhulu ukuthi singangena uchungechunge olukhulu lwephimbo), kungenziwa izinguquko ezimbili:
Nciphisa iphimbo + wandise inani lemigqa yeketanga: Isibonelo, uma ekuqaleni ukhethe umugqa owodwa wephimbo elingu-25.4mm (#100), ungashintsha ube yimigqa emibili yephimbo elingu-19.05mm (#80-2), elinikeza umthamo womthwalo ofanayo kodwa usayizi omncane.
Lungiselela inani lamazinyo e-sprocket: Ngenkathi kugcinwa iphimbo elifanayo, ukwandisa inani lamazinyo ku-sprocket yokushayela (ngokuvamile kube okungenani amazinyo angu-17) kunganciphisa ukushaqeka kokubandakanyeka kweketanga futhi kungathuthukisa ngokungaqondile ukuzivumelanisa nezimo ngesivinini esikhulu.

IV. Amaphutha Avamile Okufanele Uwagweme: Gwema Lawa Maphutha Amathathu

Ngisho nangemva kokufunda kahle inqubo yokukhetha, abantu abaningi basahluleka ngenxa yokunganaki imininingwane. Nazi ezintathu zemibono eyiphutha evame kakhulu kanye nezixazululo zayo:

Umbono Oyiphutha 1: Ukugxila kuphela kumthamo wokuthwala umthwalo ngenkathi ungazinaki iziqhathaniso zesivinini

Umbono Oyiphutha: Ukukholelwa ukuthi "iphimbo elikhulu lisho umthamo omkhulu wokuthwala umthwalo," kukhethwa iphimbo elikhulu lokusebenza ngesivinini esikhulu (isb., iketanga elingu-#120 lenjini engu-1500 rpm). Imiphumela: Amazinga omsindo weketanga adlula ama-90dB, futhi ukuqhekeka kwamapuleti eketanga kukhula zingakapheli izinyanga ezimbili kuya kwezintathu. Isixazululo: Khetha ngokuqinile amaphimbo ngokusekelwe "ekubalulekeni kwesivinini." Uma umthamo womthwalo unganele, beka phambili ukwandisa inani lemigqa kunokwandisa iphimbo.

Umbono Oyiphutha 2: Ukudideka "isivinini se-pulley yokushayela" "nesivinini se-pulley eqhutshwayo"

Umbono Oyiphutha: Ukusebenzisa isivinini se-pulley esiqhutshwayo njengento yokukhetha (isb., uma isivinini se-pulley esiqhutshwayo singama-500 rpm kanti isivinini sangempela se-pulley esiqhutshwayo singama-1500 rpm, kukhethwa iphimbo elikhulu ngokusekelwe ku-500 rpm). Imiphumela: Ukucindezeleka okukhulu okuguquguqukayo ku-chain, okuholela "ekugugeni ngokweqile kwephini" (ukuguguleka okungaphezu kuka-0.5mm ngenyanga eyodwa). Isixazululo: "Isivinini se-pulley esiqhutshwayo" kumele sisetshenziswe njengendinganiso. Uma ungaqinisekile, bala usebenzisa isivinini se-motor kanye nesilinganiso sokunciphisa (isivinini se-pulley esiqhutshwayo = isilinganiso sejubane le-motor / sokunciphisa).

Umbono Oyiphutha 3: Ukunganaki Umthelela Wokugcoba Ekufanisweni Kwejubane

Iphutha: ukucabanga ukuthi “ukukhetha iphimbo elifanele kwanele,” ukweqa ukuthambisa noma ukusebenzisa ukuthambisa okuphansi ngaphansi kwezimo zesivinini esikhulu. Umphumela: Ngisho noma iphimbo lincane, impilo yeketanga ingafinyezwa ngaphezu kuka-50%, futhi ngisho nokubanjwa yi-dry-friction kungenzeka. Isixazululo: Ezimweni zesivinini esikhulu (n ​​> 1000 rpm), ukuthambisa nge-drip noma ukuthambisa nge-oyela kumele kusetshenziswe. Ukuthambisa nge-lubricate kumele kuhambisane nesivinini (uma isivinini siphezulu, ukuthambisa nge-viscosity kuphansi).

V. Ucwaningo Lwezemboni: Ukuthuthukisa Kusukela Ekuhlulekeni Kuya Ekuzinzeni

Ulayini wokuthutha izimoto efektri yezingxenye zezimoto wawubhekene nokuphuka kweketanga kanye ngenyanga. Ngokwenza ngcono ukuhambisana kwejubane lepitch, sandise impilo yeketanga ibe yiminyaka emibili. Imininingwane imi kanje:
Uhlelo lokuqala: Isivinini se-pulley yokushayela esingu-1200 rpm, uchungechunge lomugqa owodwa olune-pitch engu-25.4mm (#100), ukudluliselwa kwamandla angu-8kW, akukho ukugcotshwa okuphoqelelwe.
Imbangela yokwehluleka: I-1200 rpm isemkhawulweni ophezulu wesivinini esiphakathi, kanti uchungechunge lwe-pitch lwama-25.4mm lubhekana nokucindezeleka okukhulu okuguquguqukayo ngalesi sivinini. Ngaphezu kwalokho, ukuntuleka kokuthambisa kuholela ekugugeni okusheshayo.
Uhlelo lokwenza ngcono: Nciphisa iphimbo libe ngu-19.05mm (#80), shintshela kuchungechunge lwemigqa emibili (#80-2), bese ufaka uhlelo lokuthambisa.
Imiphumela yokwenza ngcono: Umsindo wokusebenza kweketanga uncishisiwe kusuka ku-85dB kuya ku-72dB, ukuguguleka kwanyanga zonke kuncishisiwe kusuka ku-0.3mm kuya ku-0.05mm, kanye nokuphila kweketanga kwandiswe kusuka enyangeni eyodwa kuya ezinyangeni ezingu-24, okusindisa izindleko zokufaka esikhundleni ezingaphezu kuka-30,000 yuan minyaka yonke.

Isiphetho: Ingqikithi yokukhetha ibhalansi.
Ukukhetha iphimbo le-roller chain kanye nesivinini akulona neze isinqumo esilula “esikhulu noma esincane.” Kunalokho, kumayelana nokuthola ibhalansi efanele phakathi komthamo womthwalo, isivinini sokusebenza, isikhala sokufaka, kanye nezindleko. Ngokuqonda isimiso “sokufaniswa okuphambene,” ukusihlanganisa nenqubo yokukhetha enezinyathelo ezine ejwayelekile nokugwema izingibe ezivamile, ungaqinisekisa uhlelo lokudlulisela oluzinzile noluhlala isikhathi eside.
