Umphumela we-Polygon wama-Roller Chains kanye nokubonakaliswa kwawo

Umphumela we-Polygon wama-Roller Chains kanye nokubonakaliswa kwawo

Emkhakheni wokudlulisa ngomshini,amaketanga okugoqazisetshenziswa kabanzi emigqeni yokukhiqiza yezimboni, imishini yezolimo, ukukhiqizwa kwezimoto, ezokuthutha, kanye nezinye izinhlelo zokusebenza ngenxa yesakhiwo sazo esilula, amandla aphezulu okuthwala umthwalo, kanye nokusebenza kahle kwezindleko. Kodwa-ke, ngesikhathi sokusebenza kwe-roller chain, into eyaziwa ngokuthi “umphumela we-polygon” ithinta ngqo ukushelela kokudlulisela, ukunemba, kanye nokuphila kwesevisi, okwenza kube isici esibalulekile onjiniyela, abasebenzi bokuthenga, kanye nabanakekeli bemishini okumele basiqonde kahle.

Okokuqala, Ukwembula Umphumela We-Polygon: Uyini Umphumela We-Polygon Wezintambo Ezigoqekayo?

Ukuze siqonde umphumela we-polygon, sidinga kuqala ukubukeza isakhiwo esiyisisekelo sokudlulisa se-roller chain. Ukudluliselwa kwe-roller chain ngokuyinhloko kuqukethe i-sprocket eqhubayo, i-sprocket eqhutshwayo, kanye ne-roller chain. Njengoba i-sprocket eqhubayo ijikeleza, ukuhlanganiswa kwamazinyo e-sprocket nezixhumanisi ze-roller chain kudlulisela amandla ku-sprocket eqhutshwayo, okuqhuba izindlela zokusebenza ezilandelayo. Lokho okubizwa ngokuthi “umphumela we-polygon,” okwaziwa nangokuthi “iphutha lomphumela we-polygon,” kubhekisela esimweni sokudluliselwa kwe-roller chain lapho umugqa ogoqayo we-chain ozungeze i-sprocket wakha isimo esifana ne-polygon, okwenza isivinini se-chain esisheshayo kanye nesivinini se-angular se-sprocket eqhutshwayo sibonise ukuguquguquka okuvamile. Kalula nje, njengoba i-sprocket ijikeleza, i-chain ayiqhubeki ngesivinini esiqondile esingaguquki, kodwa kunalokho, njengokungathi ihamba eceleni kwe-polygon, isivinini sayo siyashintshashintsha njalo. Ngokufanayo, i-sprocket eqhutshwayo nayo ijikeleza ngesivinini se-angular esingaguquki, kodwa kunalokho ihlangabezana nokushintshashintsha okuvamile ngesivinini. Lokhu kuguquguquka akusikho ukungasebenzi kahle kodwa kuyisici esingokwemvelo sesakhiwo sokudlulisa uchungechunge lwe-roller, kodwa umthelela waso awunakunakwa.

Okwesibili, Ukulandelela Umsuka: Isimiso Somphumela We-Polygon

Umphumela we-polygon uvela ezicini zesakhiwo samaketanga nama-sprocket ajikelezayo. Singayiqonda ngokucacile inqubo yokukhiqiza kwawo ngezinyathelo ezilandelayo ezibalulekile:

(I) Ukucushwa kwe-Meshing kwe-Chain kanye ne-Sprocket

Uma uchungechunge lwe-roller lugoqwe nge-sprocket, njengoba i-sprocket iyingxenye eyindilinga eyakhiwe ngamazinyo amaningi, lapho isixhumanisi ngasinye se-chain meshes ne-sprocket tooth, umugqa ophakathi we-chain wakha i-curve evaliwe eyakhiwe ngemigqa eminingana ephukile. Le curve ifana ne-polygon evamile (yingakho igama elithi "umphumela we-polygon"). Inani lezinhlangothi zale "polygon" lilingana nenani lamazinyo ku-sprocket, kanti ubude obuseceleni be-"polygon" bulingana ne-chain pitch (ibanga eliphakathi kwezikhungo zama-rollers amabili aseduze).

(II) Ukuhanjiswa Kokunyakaza Kwesipikha Sokushayela

Uma i-sprocket eshayelayo ijikeleza ngesivinini esingaguquki esingu-ω₁, ijubane elijikelezayo lezinyo ngalinye ku-sprocket lihlala linjalo (v₁ = ω₁ × r₁, lapho i-r₁ kuyirediyasi yephimbo le-sprocket eshayelayo). Kodwa-ke, ngenxa yokuthi iphuzu le-meshing phakathi kwe-chain ne-sprocket lishintsha njalo kuphrofayili yezinyo le-sprocket, ibanga elivela endaweni ye-meshing kuya esikhungweni se-sprocket (okungukuthi, irediyasi yokujika ngokushesha) liyahlukahluka njalo njengoba i-sprocket ijikeleza. Ngokukhethekile, lapho ama-chain rollers efanelana kahle phansi kwe-groove phakathi kwamazinyo e-sprocket, ibanga elivela endaweni ye-meshing kuya esikhungweni se-sprocket lincane (cishe irediyasi yempande yezinyo le-sprocket); lapho ama-chain rollers ethinta amathiphu ezinyo le-sprocket, ibanga elivela endaweni ye-meshing kuya esikhungweni se-sprocket liphezulu (cishe irediyasi yesihloko sezinyo le-sprocket). Lokhu kushintshashintsha okuvamile kurediyasi yokujika ngokushesha kubangela ukuguquguquka kwejubane eliqondile le-chain.

(III) Ukuguquguquka Kwejubane Eliyindilinga Le-Driven Sprocket

Ngenxa yokuthi uchungechunge luyisici sokudlulisa esiqinile (esibhekwa njengesingenakwelulwa ngesikhathi sokudlulisa), ijubane eliqondile leketanga lidluliselwa ngqo ku-sprocket eqhutshwayo. Ijubane eliqondile le-angular ω₂ le-sprocket eqhutshwayo, ijubane eliqondile eliqondile v₂ leketanga, kanye ne-radius yokujikeleza okusheshayo r₂' ye-sprocket eqhutshwayo kwanelisa ubudlelwano ω₂ = v₂ / r₂'.

Ngenxa yokuthi ijubane eliqondile elisheshayo v₂ leketanga liyashintshashintsha, irediyasi yokujikeleza okusheshayo r₂' endaweni yokuxhuma ku-sprocket eqhutshwayo nayo iyashintsha njalo ngokujikeleza kwe-sprocket eqhutshwayo (isimiso sifana nese-sprocket eqhubayo). Lezi zici ezimbili zisebenza ndawonye ukuze kubangele ijubane elisheshayo elingu-ω₂ le-sprocket eqhutshwayo ukuthi libonise ukuguquguquka okunzima kakhulu kwezikhathi ezithile, okubuye kuthinte ukuzinza kokukhipha kwesistimu yonke yokudlulisa.

Okwesithathu, Ukwethulwa Okubonakalayo: Ukubonakaliswa Okuqondile Komphumela We-Polygon

Umphumela we-polygon uzibonakalisa ngezindlela eziningi ezinhlelweni zokudlulisa uchungechunge lwe-roller. Awuthinti nje kuphela ukunemba kokudlulisela kodwa futhi ubangela ukudlidliza, umsindo, nezinye izinkinga. Ukusebenza kwesikhathi eside kungasheshisa nokuguguleka kwezingxenye futhi kunciphise impilo yemishini. Izimpawu ezithile zifaka okulandelayo:

(1) Ukuguquguquka Kwejubane Lokudlulisa Okwesikhashana

Lokhu kuwukubonakaliswa okuqondile kakhulu nokuyinhloko komphumela we-polygon. Kokubili ijubane eliqondile le-chain kanye nejubane le-angular le-sprocket eliqhutshwayo libonisa ukuguquguquka okuvamile njengoba i-sprocket ijikeleza. Ukuphindaphinda kwalokhu kuguquguquka kuhlobene kakhulu nesivinini sokujikeleza se-sprocket kanye nenani lamazinyo: lapho ijubane le-sprocket liphezulu futhi amazinyo emancane, kulapho ukuguquguquka kwejubane kuphakeme khona. Ngaphezu kwalokho, ubukhulu bokuguquguquka kwejubane buhlobene ne-chain pitch kanye nenani lamazinyo e-sprocket: lapho i-chain pitch inkulu futhi amazinyo e-sprocket emancane, kulapho ukuguquguquka kwejubane kukhulu khona.

Isibonelo, ohlelweni lokushayela uchungechunge lwe-roller olunenani elincane lamazinyo (isb. z = 10) kanye nephimbo elikhulu (isb. p = 25.4mm), lapho i-sprocket yokushayela ijikeleza ngesivinini esikhulu (isb. n = 1500 r/min), ijubane eliqondile le-chain lingashintshashintsha ububanzi, okubangela "ukugxuma" okubonakalayo endleleni yokusebenza eqhutshwayo (isb., ibhande lokuhambisa, i-spindle yamathuluzi omshini, njll.), okuthinta kakhulu ukunemba kokudlulisela kanye nekhwalithi yomsebenzi. (2) Umthelela Nokudlidliza

Ngenxa yokushintsha okungazelelwe kwesivinini seketanga (kusuka kolunye uhlangothi olugobile kuya kolunye), imithwalo yomthelela ephindaphindwayo iyakhiqizwa ngesikhathi senqubo yokufaka i-meshing phakathi kweketanga ne-sprocket. Lo mthwalo womthelela udluliselwa ngeketanga uye ezingxenyeni ezifana ne-sprocket, i-shaft, nama-bearings, okubangela ukudlidliza kulo lonke uhlelo lokudlulisa.

Imvamisa yokudlidliza ihlobene nesivinini sokujikeleza kwe-sprocket kanye nenani lamazinyo. Lapho imvamisa yokudlidliza isondela noma ihambisana nemvamisa yemvelo yemishini, i-resonance ingenzeka, okwandisa kakhulu ubukhulu bokudlidliza. Lokhu akugcini nje ngokuphazamisa ukusebenza okuvamile kwemishini kodwa futhi kungabangela ukukhululeka nokulimala kwezingxenye, futhi kuholele ngisho nasezingozini zokuphepha.

(3) Ukungcola Komsindo

Umthelela kanye nokudlidliza yizimbangela eziyinhloko zomsindo. Ngesikhathi sokudluliselwa kwe-roller chain, umthelela we-meshing phakathi kwe-chain kanye ne-sprocket, ukushayisana phakathi kwe-chain pitches, kanye nomsindo othwalwa yisakhiwo okhiqizwa ukudlidliza okudluliselwa ohlakeni lwemishini konke kunegalelo emsindo wezinhlelo zokudluliselwa kwe-roller chain.

Uma umphumela we-polygon ubonakala kakhulu (isb., iphimbo elikhulu, amazinyo ambalwa, isivinini esiphezulu sokujikeleza), kulapho umthelela nokudlidliza kuba kubi khona, futhi kulapho umsindo uvela khona uba mkhulu. Ukuchayeka isikhathi eside emazingeni aphezulu omsindo akuthinti nje kuphela ukuzwa kwabaqhubi kodwa futhi kuphazamisa nokulawulwa kokukhiqiza kanye nokuxhumana endaweni, kunciphisa ukusebenza kahle komsebenzi.

(IV) Ukwenyuka Kokuguguleka Kwezingxenye

Imithwalo yomthelela ojikelezayo kanye nokudlidliza kusheshisa ukuguguleka kwezingxenye ezifana namaketanga okugoqa, ama-sprocket, ama-shaft, nama-bearings. Ngokukhethekile:

Ukugqokwa Kweketanga: Umthelela wandisa ukucindezeleka kokuxhumana phakathi kwama-roller eketanga, ama-bushing, nama-pin, okusheshisa ukuguguleka futhi kwandise kancane kancane i-chain pitch (eyaziwa ngokuthi “ukunwetshwa kweketanga”), okwenza umphumela we-polygon ube mubi nakakhulu.

Ukugqokwa Kwezimbobo: Ukushayisana okuvamile kanye nokungqubuzana phakathi kwamazinyo e-sprocket kanye nama-chain rollers kungabangela ukuguguleka kobuso bezinyo, ukucija izinyo, kanye nokuqhekeka kwezimpande zezinyo, okuholela ekunciphiseni ukusebenza kwe-sprocket meshing.

Ukuguga Kweshafti Ne-Bearing: Ukudlidliza kanye nokuthinta ama-shaft nama-bearing emithwalweni eyengeziwe ye-radial kanye ne-axial, okusheshisa ukuguguleka kwezinto ezigoqayo ze-bearing, imijaho yangaphakathi neyangaphandle, kanye nama-jenali, kunciphisa impilo yesevisi ye-bearing futhi kubangele ngisho nokugoba kwe-shaft.

(V) Ukunciphisa Ukusebenza Kokudlulisa

Umthelela, ukudlidliza, kanye nokulahlekelwa okwengeziwe kokungqubuzana okubangelwa umphumela we-polygon kunciphisa ukusebenza kahle kokudlulisela kwezinhlelo zokudlulisa uchungechunge lwe-roller. Ngakolunye uhlangothi, ukushintshashintsha kwesivinini kungabangela ukusebenza okungazinzile kwendlela yokusebenza, kudinga amandla engeziwe ukunqoba imithwalo eyengeziwe ebangelwa ukushintshashintsha. Ngakolunye uhlangothi, ukuguguleka okwandisiwe kwandisa ukumelana kokungqubuzana phakathi kwezingxenye, okwandisa ukulahlekelwa kwamandla. Ngesikhathi sokusebenza isikhathi eside, lokhu kusebenza okuncishisiwe kungakhuphula kakhulu ukusetshenziswa kwamandla kwemishini futhi kukhuphule izindleko zokukhiqiza.

Okwesine, Impendulo Yesayensi: Amasu Aphumelelayo Okunciphisa Umphumela We-Polygon

Nakuba umphumela we-polygon uyisici esingokwemvelo sama-roller chain transmissions futhi awunakususwa ngokuphelele, ungancishiswa ngempumelelo ngokuklama okufanele, ukukhetha, kanye nezinyathelo zokulungisa, ngaleyo ndlela kuthuthukiswe ukushelela, ukunemba, kanye nokuphila kwenkonzo kohlelo lokudlulisa. Amasu athile alandelayo:

(I) Ukuthuthukisa Umklamo Nokukhethwa Kwe-Sprocket

Ukwandisa Inani Lamazinyo E-Sprocket: Ngenkathi kuhlangatshezwana nesilinganiso sokudlulisa kanye nezidingo zesikhala sokufaka, ukwandisa inani lamazinyo e-sprocket ngokufanele kunganciphisa isilinganiso senani lezinhlangothi nobude be-"polygon," kunciphisa ukuguquguquka kwerediyasi yokujika ngokushesha futhi ngaleyo ndlela kunciphise ngempumelelo ubukhulu bokushintshashintsha kwejubane. Ngokuvamile, inani lamazinyo ku-sprocket yokushayela akufanele libe lincane kakhulu (ngokuvamile, kunconywa amazinyo angaphansi kuka-17). Kuma-transmission asheshayo noma izinhlelo zokusebenza ezidinga ukushelela okuphezulu, kufanele kukhethwe inani eliphakeme lamazinyo e-sprocket (isb., angu-25 noma ngaphezulu). Ukunciphisa amaphutha obubanzi be-sprocket pitch: Ukuthuthukisa ukunemba komshini we-sprocket nokunciphisa amaphutha okukhiqiza kanye namaphutha okugeleza okujikelezayo kububanzi be-sprocket pitch kuqinisekisa izinguquko ezibushelelezi ku-radius yokujikeleza okusheshayo yendawo ye-meshing ngesikhathi sokujikeleza kwe-sprocket, kunciphisa ukushaqeka nokudlidliza.

Ukusebenzisa ama-sprocket anamaphrofayili akhethekile amazinyo: Ezinhlelweni zokusebenza ezidinga ukudluliselwa okubushelelezi kakhulu, ama-sprocket anamaphrofayili akhethekile amazinyo (njenge-sprockets ezimise okwe-arc) angasetshenziswa. Amazinyo amise okwe-arc enza inqubo yokufaka i-meshing phakathi kweketanga ne-sprocket ibe lula, kunciphisa ukushaqeka kwe-meshing futhi ngaleyo ndlela kunciphise umthelela womphumela we-polygon.

(II) Ukukhetha Ngokufanele Amapharamitha E-Chain

Ukunciphisa iphimbo leketanga: Iphimbo leketanga lingenye yemingcele ebalulekile ethinta umphumela we-polygon. Uma iphimbo lincane, ubude obuseceleni be-"polygon" buncane futhi kuncane ukuguquguquka kwejubane eliqondile leketanga. Ngakho-ke, ngenkathi kuhlangatshezwana nezidingo zomthamo othwala umthwalo, kufanele kukhethwe amaketanga anama-pitch amancane. Kuzinhlelo zokusebenza zokudlulisa ngesivinini esikhulu, ngokunemba, amaketanga anama-pitch amancane (njengezindinganiso ze-ISO 06B kanye ne-08A). Ukukhetha amaketanga anokunemba okuphezulu: Ukuthuthukisa ukunemba kokukhiqiza amaketanga, njengokunciphisa ukuphambuka kwephimbo leketanga, ukugeleza kwe-roller radial, kanye nokucaciswa kwe-bushing-pin, kuqinisekisa ukunyakaza kweketanga okubushelelezi ngesikhathi sokusebenza futhi kunciphisa umphumela we-polygon okhuliswa ukunemba kweketanga okunganele.

Ukusebenzisa amadivayisi okuqinisa: Ukuhlela kahle amadivayisi okuqinisa uchungechunge (njengezicindezelo zasentwasahlobo kanye nezicindezelo zesisindo) kuqinisekisa ukuthi uchungechunge lugcina ukucindezeleka okufanele, lunciphisa ukuxega kweketanga kanye nokudlidliza ngesikhathi sokusebenza, ngaleyo ndlela kuncishiswe umthelela kanye nokuguquguquka kwesivinini okubangelwa umphumela we-polygon.

(III) Ukulawula amapharamitha okusebenza kohlelo lokudlulisa
Ukunciphisa isivinini sokudlulisa: Uma isivinini se-sprocket siphezulu, kulapho ukuguquguquka kwesivinini, umthelela, kanye nokudlidliza okubangelwa umphumela we-polygon kuba kukhulu. Ngakho-ke, lapho kuklanywa uhlelo lokudlulisa, isivinini sokudlulisa kufanele silinganiselwe ngokufanele ngokusekelwe ezicacisweni zeketanga kanye ne-sprocket. Kumaketanga ajwayelekile e-roller, isivinini esiphezulu esivumelekile sivame ukushiwo ngokucacile encwadini yemiyalelo yomkhiqizo futhi kufanele silandelwe ngokuqinile.

Ukuthuthukisa isilinganiso sokudlulisa: Ukukhetha isilinganiso sokudlulisa esifanele nokugwema izilinganiso ezinkulu kakhulu (ikakhulukazi ekudlulisweni kokunciphisa isivinini) kunganciphisa ukuguquguquka kwejubane le-angular le-sprocket eqhutshwayo. Kuhlelo lokudlulisa olunezigaba eziningi, isilinganiso sokudlulisa esiphezulu kufanele sinikezwe esigabeni sejubane eliphansi ukuze kuncishiswe umthelela womphumela we-polygon esigabeni sejubane eliphezulu.

(IV) Ukuqinisa Ukufakwa Nokunakekelwa Kwemishini

Qinisekisa ukunemba kokufakwa: Uma ufaka uhlelo lokudlulisa uchungechunge lwe-roller, qiniseka ukuthi iphutha lokufana phakathi kwama-axes e-sprocket okushayelayo naqhutshwayo, iphutha lebanga eliphakathi phakathi kwama-sprocket amabili, kanye nephutha lokuzulazula eliyindilinga le-sprocket end face lingaphakathi kobubanzi obuvunyelwe. Ukunemba kokufakwa okunganele kungandisa ukungalingani komthwalo kanye nokuhlangana okubi phakathi kweketanga ne-sprocket, okwandisa kakhulu umphumela we-polygon.

Ukugcoba Nokulungisa Okuvamile: Ukugcoba njalo iketanga lama-roller kanye nama-sprocket kunganciphisa ukungqubuzana phakathi kwezingxenye, ukuguguleka okuhamba kancane, kwandise impilo yesevisi yeketanga nama-sprocket, futhi kunciphise ukushaqeka nokudlidliza ngezinga elithile. Khetha i-lubricant efanele (njengowoyela noma i-grease) ngokusekelwe endaweni yokusebenza kwemishini kanye nezimo, bese ugcoba futhi uhlole imishini ngezikhathi ezibekiwe. Shintsha izingxenye ezigugile ngokushesha: Lapho iketanga libonisa ukunwebeka okukhulu kwe-pitch (ngokuvamile okungaphezu kuka-3% we-pitch yokuqala), ukuguguleka kwe-roller kuba kubi kakhulu, noma ukuguguleka kwamazinyo e-sprocket kudlula umkhawulo obekiwe, iketanga noma i-sprocket kufanele ishintshwe ngokushesha ukuze kuvinjelwe ukuguguleka okukhulu kwezingxenye ukuthi kukhulise umphumela we-polygon futhi okungase kuholele ekwehlulekeni kwemishini.

Okwesihlanu, Isifinyezo
Umphumela we-polygon wamaketanga okugoqa uyisici esiyingqayizivele sesakhiwo sawo sokudlulisa. Uthinta kakhulu ukusebenza kanye nokuphila kwesevisi yesistimu yokudlulisa ngokuthinta ukuzinza kwesivinini sokudlulisa, ukudala ukudlidliza kokwethuka nomsindo, kanye nokusheshisa ukuguguleka kwezingxenye. Kodwa-ke, ngokuqonda kahle izimiso kanye nokubonakaliswa okuthile komphumela we-polygon kanye nokusebenzisa amasu okunciphisa esayensi nafanele (njengokwenza ngcono ukukhetha kwe-sprocket kanye neketanga, ukulawula amapharamitha okusebenza, kanye nokuqinisa ukufakwa nokugcinwa), singanciphisa ngempumelelo imiphumela emibi yomphumela we-polygon futhi sisebenzise ngokugcwele izinzuzo zokudluliselwa kweketanga lokugoqa.
