I-idler yokuhambisa eyilwe ngokufanelekileyo iya kuba nesiphumo esihle kwisihambisi sebhanti

Ukuqeqesha okanye ukulandelela ibhanti kwi-stacker yakho ye-radial okanyeinkqubo yokuhambisa rolleryinkqubo yokulungelelanisa i-idlers, i-pulleys, kunye neemeko zokulayisha ngendlela eya kulungisa naluphi na utyekelo lwebhanti ukuqhuba ngaphandle kwendawo ephakathi.Umgaqo osisiseko omele ugcinwe engqondweni xa ulandelela ibhanti lokuhambisa ulula, "IBHATHI LIHAMBA NGESIPHELO SE-ROLL/IDLER IQHAGAMSHELANA KUQALA."

Xa zonke iinxalenye zebhanti zihamba ngenxalenye yobude bomthumeli, imbangela mhlawumbi kukulungelelaniswa okanye ukulinganisa kwe-radial stacker okanye izakhiwo zokuhambisa, i-idlers, okanye iipuli kuloo ndawo.

Ukuba inxenye enye okanye ngaphezulu ibhanti iyabaleka kuzo zonke iindawo ecaleniumhambisi, imbangela inokwenzeka ngakumbi kwibhanti ngokwayo, kwii-splices, okanye ekulayisheni ibhanti.Xa ibhanti lilayishwa lisuka embindini, umbindi womxhuzulane womthwalo udla ngokufumana umbindi wamavila ahambahambayo, ngaloo ndlela ekhokelela ibhanti kumphetho walo olayishwe kancinci.

Le yimigaqo esisiseko yokuxilongwa kweengxaki eziqhuba ibhanti.Ukudityaniswa kwezi zinto ngamanye amaxesha kuvelisa iimeko ezingabonakali ngokucacileyo ukuba zibangele, kodwa ukuba inani elaneleyo lokuguqulwa kwebhanti liyabonwa, ipateni yokuqhuba iya kucaca kwaye isizathu sichazwe.Iimeko eziqhelekileyo xa ipateni ingaveliyo yileyo yokubaleka okungahambi kakuhle, enokuthi ifumaneke kwibhanti engalayishwanga engakhumbi kakuhle, okanye ibhanti elilayishiweyo elingawufumaniyo umthwalo walo ugxile ngokulinganayo.

Imiba echaphazela uQeqesho lweBhanti yokuThutha

　　Reels Pulleys kunye Snubs

Isiphumo esincinci sokulawula sifumaneka kwisithsaba seepuli zokuhambisa.Isithsaba sisebenza kakhulu xa kukho ixesha elide elingaxhaswanga lokubhinca, (malunga nobubanzi obuphindwe kane bebhanti) ukusondela kwipuli.Njengoko oku kungenakwenzeka kwicala elithwele umthumeli, ukuthweswa isithsaba sentloko akusebenzi kwaye akufanelanga ukusasazwa kwe-lateral mal-tension eyivelisa kwibhanti.

Iipuli zomsila zinokuba nesithuba esingaxhaswanga sebhanti esisondela kuzo kwaye ukuthwesa isithsaba kunokunceda ngaphandle kwaxa zikwindawo yoxinzelelo oluphezulu lwebhanti.Inzuzo enkulu apha kukuba isithsaba, kwinqanaba elithile, sincedisa ekugxininiseni ibhanti njengoko idlula ngaphantsi kwendawo yokulayisha, eyimfuneko ekulayisheni kakuhle.Iipuli zokuthatha ngamanye amaxesha zithweswe isithsaba ukukhathalela nakuphi na ukungahambi kakuhle okuncinci okwenzeka kwikhareji yokuthatha njengoko itshintsha indawo.

Zonke iipuli kufuneka zibe kwinqanaba kunye ne-axis yazo kwi-90 ° ukuya kwindlela ejoliswe kuyo ibhanti.Kufuneka zigcinwe ngaloo ndlela kwaye zingatshintshwa njengendlela yoqeqesho, ngaphandle nje kokuba ii-snub pulleys zinokushenxiswa i-axis yazo xa ezinye iindlela zoqeqesho zibonelela ngezilungiso ezinganelanga.Iipuli kunye neentsimbi zazo ngaphandle kwe-90 ° ukuya kwindlela yebhanti ziya kukhokelela ibhanti kwicala lomda webhanti eqala ukuqhagamshelana ne-pulley ephosakeleyo.Xa iipulleys zingekho kwinqanaba, ibhanti livame ukugijima ukuya kwicala eliphantsi.Oku kuchasene nengxelo endala ethi "umgaqo wesithupha" wokuba ibhanti libaleka kwicala "eliphezulu" lepulley.Xa ukudityaniswa kwezi zimbini kwenzeka, lowo unempembelelo enamandla uya kubonakala ekusebenzeni kwebhanti.

　Ukuthwala i-Idler

Ukuqeqesha ibhanti kunye ne-idlers ye-troughing ifezekiswa ngeendlela ezimbini.Ukutshintsha i-axis ye-idler malunga nendlela yebhanti, eyaziwa ngokuba "yi-idlers enkqonkqozayo," iyasebenza apho ibhanti lonke libalekela kwelinye icala kunye nenxalenye yokuhambisa okanye i-radial stacker.Ibhanti inokuthi igxininiswe "ngokubetha" phambili (kwindlela yokuhamba ngebhanti) ekupheleni kwe-idler apho ibhanti lihamba khona.I-idlers eguqukayo ngale ndlela kufuneka isasazwe kubude bomhambisi, okanye i-radial stacker, eyandulela ummandla wenkathazo.Kuya kuqondwa ukuba ibhanti linokwenziwa ukuba libaleke ngokuthe tye isiqingatha samavila "sinkqonkqoze" kwelinye icala nesiqingatha sesinye, kodwa oku kuya kuba yindleko yokwenyuka kwengxabano phakathi kwebhanti kunye namavila.Ngenxa yesi sizathu, bonke abangasebenziyo kufuneka baqale baphindwe kabini kunye nendlela yebhanti, kwaye kuphela ubuncinci bokutshintshwa kwamavila asetyenziswe njengendlela yokuqeqesha.Ukuba ibhanti ligqitywe ngokugqithiseleyo ngokuguquguquka kwe-idlers, kufuneka ibuyiselwe ngokubuyisela umva ama-idlers afanayo, kungekhona ngokutshintshela i-idlers eyongezelelweyo kwelinye icala.

Ngokucacileyo, olo tshintsho lungasebenziyo lusebenza kwicala elinye kuphela lokuhamba ngebhanti.Ukuba ibhanti liguqulwa, i-idler etshintshileyo, ilungisa kwelinye icala, iya kuphosakela kwelinye.Yiyo loo nto iibhanti ezibuyisela umva kufuneka zibe nazo zonke ii-idlers ziphindwe kabini kwaye zishiywe ngaloo ndlela.Naluphi na ulungiso olufunekayo lunokubonelelwa ngee-idlers ezizilungelelanisayo ezenzelwe ukubuyisela umva umsebenzi.Ayizizo zonke ii-self-aligners ezilolu hlobo, njengoko ezinye zisebenza kwicala elinye kuphela.

Ukutshekisa i-idler ehamba phambili (kungekho ngaphezu kwe-2 °) kwicala lokuhamba ngebhanti kuvelisa umphumo wokuzilungelelanisa.Amavila anokuthambeka ngolu hlobo ngokushenxa umlenze ongasemva weqonga elingasebenziyo.Apha kwakhona, le ndlela ayanelisi apho amabhanti anokubuyiselwa umva.

Le ndlela inenzuzo ngaphezu "kokunkqonkqoza i-idlers" kuba iya kulungisa ukuhamba kwebhanti ukuya kwelinye icala le-idler, kungoko iluncedo ekuqeqesheni amabhanti angaqhelekanga.Inobubi bokukhuthaza ukunxiba okukhawulezileyo kwesigqubuthelo sepuli ngenxa yokukhuhlana okwandileyo kwimiqulu.Ngoko ke kufuneka isetyenziswe ngokucothayo kangangoko kunokwenzeka – ngakumbi kwii-engile eziphezulu zokuchwechwela.

Abakhethekileyo, abazilungelelanisayo abavilayo njengalowo ungasekunene bayafumaneka ukunceda ekuqeqesheni ibhanti.

Buyisela Abangasebenziyo

Amavila abuyayo, ukuba tyaba, awanikeli mpembelelo yaso njengakwimeko yamavila athambekileyo.Nangona kunjalo, ngokuguqula i-axis yabo (ukubetha) ngokubhekiselele kwindlela yebhanti, i-return roll ingasetyenziselwa ukubonelela ngempembelelo yokulungiswa rhoqo kwicala elinye.Njengakwimeko ye-troughing rolls, isiphelo somqulu apho ibhanti litshintshela khona kufuneka lihanjiswe ixesha elide kwicala lokuhamba kwebhanti lokubuyisela ukubonelela ukulungiswa.

Iincwadi ezizilungelelanisayo zokubuya nazo kufuneka zisetyenziswe.Ezi pivoted malunga nephini eliphakathi.I-Pivoting ye-roll malunga nale pin iphuma kwi-off-center belt kunye ne-idler roll axis iguqulwa ngokubhekiselele kwindlela yebhanti kwisenzo sokuzilungisa.Abanye abangasebenziyo ababuyayo benziwa ngemiqulu emibini eyenza i-10 ° ukuya kwi-20 ° V-trough, esebenzayo ekuncedeni ukuqeqesha ukubuya.

Uncedo olongezelelweyo lokumisa ibhanti njengoko lusondela kwipuli yomsila lunokubakho ngokuhambela phambili kancinane kunye nokunyusa iziphelo ezitshintshanayo ze-return rolls kufutshane nepuli yomsila.

Ukuqinisekisa ngokuSebenza koLuhlu loQeqesho

Ngokwesiqhelo, uxinzelelo olongezelelweyo luyanqweneleka kumavila azenzelayo

kwaye, kwezinye iimeko, kuma-idlers asemgangathweni apho kufuneka impembelelo yoqeqesho olumandla.Enye indlela yokuphumeza oku kukuphakamisa loo mavila ngaphezu komgca wamavila akufutshane.I-Idlers okanye i-bend pulleys kwi-convex (i-hump) igophe ecaleni kwecala lokubuya linoxinzelelo olongezelelweyo ngenxa yamacandelo e-belt tension kwaye ngoko ke ziindawo zoqeqesho ezisebenzayo.Iinqwelo ezizilungelelanisayo ezisecaleni akufuneki zibekwe kwigophe eligoso-gophe kuba iindawo zazo eziphakamileyo zinokukhuthaza ukusilela kokudibana kwesidumbu.

　　IiRola zeSikhokelo esisecaleni

Izikhokelo zolu hlobo azikhuthazwa ukuba zisetyenziswe ekwenzeni amabhanti ahamba ngokuthe tye.Zingasetyenziselwa ukuncedisa ekuqeqesheni ibhanti ekuqaleni ukunqanda ukuba ingaqhubeki kwiipuli kunye nokulimala ngokwalo ngokuchasene nesakhiwo senkqubo yokuhambisa.Basenokusetyenziselwa ukunika uhlobo olufanayo lokhuseleko kwibhanti njengomlinganiselo wonxunguphalo, ngaphandle kokuba abawuchukumisi umphetho webhanti xa lisebenza ngokuqhelekileyo.Ukuba bathwele ibhanti ngokuqhubekayo, nangona bekhululekile ukuqengqeleka, bakholisa ukuguga emphethweni webhanti kwaye ekugqibeleni babangele ukwahlukana kweply ecaleni komphetho.Iirola zesikhokelo ezisecaleni akufuneki zibekwe ukuze zithwale ngokuchasene nomphetho webhanti xa ibhanti sele likwipulley.Ngeli xesha, akukho xinzelelo lomda lunokuhambisa ibhanti ngasecaleni.

Ibhanti ngokwalo

Ibhanti elinokuqina okugqithisileyo kwecala, ngokumalunga nobubanzi balo, kuya kuba nzima ngakumbi ukuqeqesha ngenxa yokungadibanisi nomqulu ophakathi we-idler ephetheyo.Ukuqaphela le nyaniso kwenza umsebenzisi ukuba athathe amanyathelo okukhusela kwaye, ukuba kuyimfuneko, ukulayisha ibhanti ngexesha loqeqesho ukuphucula amandla ayo okulawula.Ukuphononongwa koyilo lwesakhono sokusikelwa umda kuya kuyinqanda le ngxaki.

Amanye amabhanti amatsha anokuthanda ukubaleka kwicala elinye, kwinxalenye ethile okanye iinxalenye zobude bawo, ngenxa yokwabiwa koxinzelelo lwethutyana olusecaleni.Ukusebenza kwebhanti phantsi koxinzelelo kulungisa le meko kuzo zonke iimeko.Ukusetyenziswa kwamavila alungelelanisiweyo kuya kunceda ekwenzeni ulungiso.
