Ubudlelwane Phakathi Kokukhethwa Kwe-Roller Chain Pitch kunye neSantya
Kwiinkqubo zothumelo lwemizi-mveliso, iphithi yetsheyini yeroli kunye nesantya zezona zinto zibalulekileyo ezimisela ukusebenza kakuhle kothumelo, ubomi bezixhobo, kunye nokuzinza kokusebenza. Iinjineli ezininzi kunye nabasebenzi bokuthenga, abagxile kakhulu kumthamo wokuthwala umthwalo ngexesha lokukhetha, badla ngokungawunaki ukuhambelana kwezi zinto zimbini. Oku ekugqibeleni kukhokelela ekugugeni nasekuqhekekeni kwetsheyini ngaphambi kwexesha, kwanakwixesha lonke lokungasebenzi komgca wemveliso. Eli nqaku liza kuhlalutya imigaqo esisiseko kunye nolwalamano oluphakathi kwephithi kunye nesantya, libonelele ngeendlela zokukhetha ezisebenzayo ukukunceda ukhethe itshiyini yeroli efanelekileyo kwiimeko ezahlukeneyo zokusebenza.
I. Ukuqonda Iingcamango Ezimbini Eziphambili: Inkcazo kunye nokubaluleka kweShishini kwePitch kunye neSpeed
Ngaphambi kokuba uhlalutye ulwalamano phakathi kwezi zimbini, kubalulekile ukucacisa iinkcazo ezisisiseko—oku kubalulekile ukuze kuthintelwe iimpazamo zokukhetha. Nokuba usebenzisa iiroller chains ze-ANSI (American Standard), ISO (International Standard), okanye GB (National Standard), impembelelo ephambili yepitch kunye nesantya ihlala ingaguquguquki.
1. I-Roller Chain Pitch: Imisela "Umthamo woMthwalo" kunye "Nokutyibilika Kokusebenza"
I-pitch yimilinganiselo ephambili ye-roller chain, ibhekisa kumgama ophakathi kweziko lee-roller ezimbini ezikufutshane (ezibonakaliswa luphawu "p" kwaye zihlala zilinganiswa nge-mm okanye i-intshi). Imisela ngokuthe ngqo iimpawu ezimbini ze-key chain:
Umthamo woMthwalo: Iphimbo elikhulu lidla ngokubangela ukuba kubekho izinto ezinkulu zetsheyini ezifana neepleyiti kunye neephini, kunye nomthwalo ophezulu (ongashukumiyo noguquguqukayo) onokuthwalwa, nto leyo eyenza ukuba ifaneleke kwizicelo ezinzima (ezifana noomatshini bokwemba kunye nezixhobo zokuhambisa ezinzima).
Ukutyibilika Kokusebenza: Iphimbo elincinci linciphisa "impembelelo rhoqo" xa itsheyini idibana ne-sprocket, nto leyo ebangela ukungcangcazela okuncinci kunye nengxolo encinci ngexesha lokudluliselwa. Oku kuyenza ifaneleke ngakumbi kwizicelo ezifuna uzinzo oluphezulu (ezifana nezixhobo zoomatshini abachanekileyo kunye nezixhobo zokupakisha ukutya).
2. Isantya sokujikeleza: Sichaza "uxinzelelo olutshintshayo" kunye "nesantya sokunxiba"
Isantya sokujikeleza apha sibhekisa ngokukodwa kwisantya se-sprocket eqhubayo apho i-chain iqhagamshelwe khona (eboniswa luphawu "n" kwaye idla ngokulinganiswa kwi-r/min), kungekhona isantya sesiphelo esiqhutywayo. Impembelelo yayo kwi-chain ibonakaliswa ikakhulu kwiinkalo ezimbini:
Uxinzelelo olutshintshayo: Okukhona isantya siphezulu, kokukhona amandla amakhulu e-centrifugal aveliswa yitsheyini ngexesha lokusebenza. Oku kwandisa kakhulu "umthwalo wempembelelo" xa itsheyini idibanisa i-mesh namazinyo e-sprocket (ngokufana nempembelelo yemoto edlula i-speed bump ngesantya esiphezulu).
Izinga lokuguguleka: Okukhona isantya siphezulu, kokukhona i-chain meshes ene-sprocket inyuka amaxesha amaninzi kwaye ukujikeleza kwee-rollers kunye nee-pin kuyanda. Inani elipheleleyo lokuguguleka kwixesha elifanayo liyanda ngokulinganayo, nto leyo enciphisa ngokuthe ngqo ubomi benkonzo ye-chain.
II. I-Core Logic: Umgaqo "wokufanisa okuchaseneyo" wePitch kunye neSpeed
Iindlela ezininzi zoshishino ziye zaqinisekisa ukuba i-roller chain pitch kunye ne-speed zinobudlelwane obucacileyo "bokufanisa okuchaseneyo" - oko kukuthi, okukhona isantya siphezulu, kokukhona i-pitch ifanele ibe ncinci, ngelixa isantya siphantsi, kokukhona i-pitch inokuba nkulu. Umongo walo mgaqo kukulinganisela "iimfuno zomthwalo" kunye "nomngcipheko woxinzelelo oluguquguqukayo." Oku kungahlulwahlulwa kube ziinkalo ezintathu:
1. Ukusebenza ngesantya esiphezulu (ngesiqhelo yi-n > 1500 r/min): Iphimbo elincinci libalulekile.
Xa isantya se-drive sprocket sidlula i-1500 r/min (njengakwiifeni nakwii-motor drives ezincinci), uxinzelelo oluguquguqukayo kunye namandla e-centrifugal kwi-chain ayanda kakhulu. Ukusebenzisa i-large-pitch chain kule meko kunokukhokelela kwiingxaki ezimbini ezibalulekileyo:
Umthwalo ogqithisileyo: Iitsheyini ezinkulu zineendawo ezinkulu zokunxibelelana, nto leyo ebangela indawo enkulu yokudibana kunye namandla okudibana namazinyo e-sprocket ngexesha lokudibanisa i-mesh. Oku kunokubangela ngokulula "ukutsiba kwekhonkco" okanye "ukuphuka kwamazinyo e-sprocket" ngesantya esiphezulu.
Ukutyibilika okubangelwa ngamandla e-Centrifugal: Iitsheyini ezinkulu zinobunzima obukhulu bokufa, kwaye amandla e-centrifugal akhiqizwa ngesantya esiphezulu anokubangela ukuba itsheyini iphume kumazinyo e-sprocket, nto leyo ebangela "ukuwa kwetsheyini" okanye "ukutyibilika kwedrayivu." Kwiimeko ezinzima, oku kunokukhokelela ekungqubaneni kwezixhobo. Ke ngoko, kwizicelo zesantya esiphezulu, iitsheyini ezine-pitch ye-12.7mm (1/2 intshi) okanye ngaphantsi zihlala zikhethwa, ezifana nothotho lwe-ANSI #40 kunye noluhlu lwe-#50, okanye uthotho lwe-ISO 08B kunye noluhlu lwe-10B.
2. Usetyenziso lwesantya esiphakathi (ngesiqhelo yi-500 r/min < n ≤ 1500 r/min): Khetha iphimbo eliphakathi.
Ukusetyenziswa kwesantya esiphakathi kuxhaphake kakhulu kwizicelo zoshishino (ezifana nee-conveyors, ii-spindles zezixhobo zoomatshini, kunye noomatshini bezolimo). Ulungelelwano phakathi kweemfuno zomthwalo kunye neemfuno zokuthamba kubalulekile.
Kwimithwalo ephakathi (njengee-conveyors ezikhanyayo ezinamandla alinganiselweyo angama-10kW okanye ngaphantsi), iitsheyini ezinepitch ye-12.7mm ukuya kwi-19.05mm (1/2 intshi ukuya kwi-3/4 intshi) ziyacetyiswa, ezifana nothotho lwe-ANSI #60 kunye no-#80. Kwimithwalo ephezulu (njengezixhobo zoomatshini eziphakathi ezinamandla alinganiselweyo angama-10kW-20kW), itsheyini enepitch ye-19.05mm-25.4mm (3/4-intshi ukuya kwi-1-intshi), ezifana nothotho lwe-ANSI #100 kunye no-#120, zinokukhethwa. Nangona kunjalo, ukuqinisekiswa okongezelelweyo kobubanzi bezinyo le-sprocket kuyimfuneko ukuthintela ukungazinzi kwe-meshing.
3. Ukusebenza ngesantya esiphantsi (ngesiqhelo yi-n ≤ 500 r/min): Ikhonkco elikhulu lepitch lingakhetha.
Kwiimeko zesantya esiphantsi (ezifana nee-crushers zemigodi kunye nee-hoists ezinzima), uxinzelelo oluguqukayo lwetsheyini kunye namandla e-centrifugal aphantsi kakhulu. Umthamo wokuthwala umthwalo uba yeyona mfuneko iphambili, kwaye iingenelo zetsheyini enkulu zingasetyenziswa ngokupheleleyo:
Iitsheyini ezinkulu zinika amandla amakhulu kwaye zinokumelana nemithwalo yempembelelo yamakhulu e-kN, zithintela ukwaphuka kwepleyiti yetsheyini kunye nokugoba kwephini phantsi kwemithwalo enzima.
Izinga lokuguguleka liphantsi xa isantya siphantsi, nto leyo evumela iitsheyini ezinkulu ukuba zigcine ubomi obuhambelana nobomi bezixhobo zizonke, nto leyo esusa isidingo sokutshintshwa rhoqo (ngesiqhelo iminyaka emi-2-3). Iitsheyini ezinepitch ≥ 25.4mm (1 intshi), ezifana ne-ANSI #140 kunye ne-#160 series, okanye iitsheyini ezinkulu ezenziwe ngokwezifiso, ezisindayo, zisetyenziswa kakhulu kule meko.
III. Isikhokelo Esisebenzayo: Tshatisa ngokuchanekileyo iPitch kunye neSpeed kwiiNyathelo ezi-4
Emva kokuqonda le ngcamango, lixesha lokuyisebenzisa ngeenkqubo ezimiselweyo. La manyathelo ma-4 alandelayo aya kukunceda ukhethe ngokukhawuleza ikhonkco elifanelekileyo kwaye uphephe iimpazamo ezibangelwa kukuthembela kumava:
Inyathelo 1: Chonga iiParamitha eziPhambili – Qokelela iiDatha eziPhambili ezi-3 kuqala
Ngaphambi kokuba ukhethe itsheyini, kufuneka ufumane ezi parameters zintathu ziphambili zesixhobo; akukho nanye kuzo enokungashiywa:
Isantya se-sprocket yokuqhuba (n): Fumana oku ngqo kwi-motor okanye kwi-drive end manual. Ukuba isantya se-drive end kuphela esifumanekayo, bala umva usebenzisa ifomula ethi “Umlinganiselo wokudluliselwa = inani lamazinyo kwi-sprocket yokuqhuba / inani lamazinyo kwi-sprocket eqhutywayo.”
Amandla okudlulisa alinganisiweyo (P): La ngamandla (kwi-kW) afunekayo ukuze adluliselwe sisixhobo ngexesha lokusebenza okuqhelekileyo. Oku kuquka imithwalo ephezulu (efana nemithwalo yokwethuka ngexesha lokuqalisa, edla ngokubalwa ngokuphindwe kayi-1.2-1.5 yamandla alinganisiweyo).
Indawo yokusebenza: Jonga uthuli, ioyile, amaqondo obushushu aphezulu (>80°C), okanye iigesi ezirhabaxa. Kwiindawo ezirhabaxa, khetha iitsheyini ezinee-lubrication grooves kunye nee-anti-corrosion coating. I-pitch kufuneka inyuswe nge-10%-20% ukuvumela ukuguguleka.
Inyathelo lesi-2: Ukukhetha uLuhlu lwePitch oluPhambili olusekelwe kwisantya
Jonga kwitheyibhile engezantsi ukuze ubone uluhlu lwepitch yokuqala olusekelwe kwisantya se-drive sprocket (usebenzisa i-ANSI standard chain njengomzekelo; eminye imigangatho ingaguqulwa ngokufanelekileyo):
Isantya seSprocket yokuqhuba (r/min) Uluhlu lwePitch olucetyiswayo (mm) Uthotho lweeChain ze-ANSI ezihambelanayo Izicelo eziqhelekileyo
>1500 6.35-12.7 #25, #35, #40 Iifeni, Iimoto ezincinci
500-1500 12.7-25.4 #50, #60, #80, #100 IiConveyors, Izixhobo zoMatshini
<500 25.4-50.8 #120, #140, #160 Isityumzi, iLifti
Inyathelo lesi-3: Qinisekisa ukuba iPitch ihlangabezana nomthamo womthwalo usebenzisa amandla
Emva kokukhetha iphimbo lokuqala, qinisekisa ukuba itsheyini inokumelana namandla alinganisiweyo usebenzisa i-“Power Calculation Formula” ukuze kuthintelwe ukungaphumeleli kokugqithisa. Ukuthatha itsheyini yeroller esemgangathweni ye-ISO njengomzekelo, ifomyula elula yile ilandelayo:
Uthumelo lwamandla oluvumelekileyo lweTyeya (P₀) = K₁ × K₂ × Pₙ
Apho: I-K₁ yeyona nto ilungisa isantya (isantya esiphezulu sibangela i-K₁ ephantsi, enokufumaneka kwikhathalogu yetsheyini); I-K₂ yeyona nto ilungisa imeko yokusebenza (0.7-0.9 kwiindawo ezirhabaxa, 1.0-1.2 kwiindawo ezicocekileyo); kwaye i-Pₙ ngamandla alinganisiweyo etsheyini (anokufumaneka ngepitshi kwikhathalogu yomenzi).
Imeko yokuqinisekisa: I-P₀ kufuneka ihlangabezane ne-≥ 1.2 × P (i-1.2 yinto yokhuseleko, enokwandiswa ibe yi-1.5 kwiimeko ezinzima).
Inyathelo lesi-4: Lungisa isicwangciso sokugqibela ngokusekelwe kwindawo yokufakela.
Ukuba iphithi ekhethiweyo ekuqaleni inqunyelwe yindawo yokufaka (umz., indawo yangaphakathi yesixhobo incinci kakhulu ukuba ingangenisa ikhonkco elikhulu), kunokwenziwa utshintsho olubini:
Nciphisa iphithi + nyusa inani lemigca yetsheyini: Umzekelo, ukuba ekuqaleni ukhethe umqolo omnye wephithi engama-25.4mm (#100), ungatshintshela kwimigca emibini yephithi engama-19.05mm (#80-2), enika amandla omthwalo afanayo kodwa ubukhulu obuncinci.
Yenza ngcono inani lamazinyo e-sprocket: Ngelixa kugcinwa i-pitch efanayo, ukwandisa inani lamazinyo kwi-sprocket yokuqhuba (ngesiqhelo ukuya kumazinyo ali-17 ubuncinane) kunokunciphisa ukubetheka kwe-chain entanyeni kwaye kungaphucula ngokungathanga ngqo ukuguquguquka kwesantya esiphezulu.
IV. Iimpazamo Eziqhelekileyo Okufanele Uziphephe: Ziphephe Ezi Zimpazamo Zithathu
Nasemva kokuba beyifundile inkqubo yokukhetha, abantu abaninzi basasilela ngenxa yokungazinaki iinkcukacha. Nazi ezintathu zezona ngcamango zingaqhelekanga kunye nezisombululo zazo:
Ingcamango Engachanekanga 1: Ukugxila kuphela kumthamo wokuthwala umthwalo ngelixa ungawunaki ukuhambelana kwesantya
Ingcamango Engachanekanga: Ukukholelwa ekubeni "i-pitch enkulu ithetha umthamo omkhulu wokuthwala umthwalo," kukhethwa i-pitch chain enkulu yokusebenza ngesantya esiphezulu (umz., i-#120 chain kwi-motor ye-1500 rpm). Iziphumo: Amanqanaba engxolo ye-chain adlula i-90dB, kwaye ukuqhekeka kwe-chain plate kuvela kwiinyanga ezimbini ukuya kwezintathu. Isisombululo: Khetha ngokungqongqo ii-pitch ngokusekelwe "kwi-speed priority." Ukuba umthamo womthwalo awonelanga, beka phambili ukunyusa inani lemigca endaweni yokwandisa i-pitch.
Ingcamango engeyiyo 2: Ukudideka "isantya se-pulley yokuqhuba" kunye "nesantya se-pulley eqhutywayo"
Ingcamango ephosakeleyo: Ukusebenzisa isantya se-pulley esiqhutywayo njengesici sokukhetha (umz., ukuba isantya se-pulley esiqhutywayo singu-500 rpm kwaye isantya sokwenyani se-pulley singu-1500 rpm, i-pitch enkulu ikhethwa ngokusekelwe kwi-500 rpm). Iziphumo: Uxinzelelo olugqithisileyo olunamandla kwikhonkco, okubangela "ukuguguleka okugqithisileyo kwephini" (ukuguguleka okungaphezulu kwe-0.5mm kwinyanga enye). Isisombululo: "Isantya se-pulley esiqhutywayo" kufuneka sisetyenziswe njengomgangatho. Ukuba awuqinisekanga, bala usebenzisa isantya se-motor kunye nomlinganiselo wokunciphisa (isantya se-pulley esiqhutywayo = umlinganiselo wesantya se-motor / ukunciphisa).
Ingcamango Engachanekanga 3: Ukungayinaki Impembelelo Yokuthambisa Kwimilinganiselo Yesantya-Iphithi
Impazamo: ukucinga ukuba "ukukhetha iphimbo elifanelekileyo kwanele," ukutsiba i-lubricant okanye ukusebenzisa i-lubricant engaphantsi phantsi kweemeko zesantya esiphezulu. Isiphumo: Nokuba iphimbo lincinci, ubomi betsheyini bunokuncipha ngaphezu kwama-50%, kwaye nokubamba i-dry-friction kunokwenzeka. Isisombululo: Kwiimeko zesantya esiphezulu (n > 1000 rpm), i-drip lubricant okanye i-oil bath lubricant kufuneka isetyenziswe. I-lubricant viscosity kufuneka ihambelane nesantya (okukhona isantya siphezulu, kokukhona i-viscosity iphantsi).
V. Isifundo seMeko yoShishino: Ukuphucula ukusuka ekuHlekeni ukuya ekuZinzeni
Umgca wokuhambisa impahla kwifektri yezixhobo zeemoto wawufumana ukwaphuka kwetyathanga kube kanye ngenyanga. Ngokuphucula ukuhambelana kwesantya sepitch, sandise ubomi betyathanga ukuya kwiminyaka emibini. Iinkcukacha zezi zilandelayo:
Isicwangciso sokuqala: Isantya se-pulley yokuqhuba siyi-1200 rpm, ikhonkco lomqolo omnye eline-pitch ye-25.4mm (#100), udluliselo lwamandla lwe-8kW, akukho kuthambisa okunyanzelekileyo.
Isizathu sokungaphumeleli: I-1200 rpm ikwindawo ephezulu yesantya esiphakathi, kwaye i-25.4mm pitch chain ifumana uxinzelelo olunamandla kakhulu kwesi santya. Ngaphezu koko, ukungabikho kwe-lubrication kukhokelela ekugugeni ngokukhawuleza.
Isicwangciso sokwenza ngcono: Nciphisa iphimbo liye kwi-19.05mm (#80), tshintshela kwikhonkco elinemigca emibini (#80-2), uze wongeze inkqubo yokuthambisa ngedriphu.
Iziphumo zokuphucula: Ingxolo yokusebenza kwetsheyini incitshisiwe ukusuka kwi-85dB ukuya kwi-72dB, ukuguguleka kwenyanga kuncitshisiwe ukusuka kwi-0.3mm ukuya kwi-0.05mm, kwaye ubomi betsheyini buyandiswa ukusuka kwinyanga e-1 ukuya kwiinyanga ezingama-24, nto leyo esindisa ngaphezulu kwe-30,000 yuan kwiindleko zokutshintsha ngonyaka.
Isiphelo: Eyona nto iphambili ekukhetheni kukulinganisela.
Ukukhetha i-roller chain pitch kunye nesantya akusosigqibo silula "esikhulu okanye esincinci." Endaweni yoko, kumalunga nokufumana ibhalansi efanelekileyo phakathi komthamo womthwalo, isantya sokusebenza, indawo yokufaka, kunye neendleko. Ngokuqonda umgaqo "wokufanisa umva," ukuwudibanisa nenkqubo yokukhetha enamanyathelo amane emiselweyo kwaye uphephe imigibe eqhelekileyo, unokuqinisekisa inkqubo yokudlulisela ezinzileyo nehlala ixesha elide.
