Ukuqhathanisa phakathi kwama-ball bearings nama-roller bearings
Umehluko omkhulu phakathi Ukuthwala ibholaAma-s nama-roller bearings ayisimo kanye nemodi yokuxhumana yento egoqayo, ethinta ngqo ukusebenza kwayo kanye nezimo zokusetshenziswa.
Isimiso Sokwakheka Nokusebenza
Ukuthwala ibhola:
Izinto ezigoqekayo zebhereyi yebhola ziyindilinga futhi ukuxhumana nemigwaqo yomjaho kuyi-point contact. Njengoba umthwalo ukhula, i-contact point iba yindawo eyindilinga, enikeza amabhereyi ebhola ukumelana okuncane kokungqubuzana kanye nokukhiqizwa okuncane kokushisa lapho ejikeleza ngesivinini esikhulu, okulungele izimo ezijikelezayo ngesivinini esikhulu .
Izinto ezigoqayo ze-roller bearing zisesimweni esiyindilinga noma esiyindilinga, futhi ukuxhumana nemigwaqo yomjaho kuyindlela yokuxhumana yomugqa. Indawo enkulu yokuxhumana ingasabalalisa umthwalo omkhulu, ngaleyo ndlela ibe namandla okuthwala aphezulu, kodwa imelane nokungqubuzana okukhulu, ifanelekela umthwalo osindayo kodwa izimo zesivinini sokujikeleza esiphansi .
Izici zokusebenza
Ukuthwala ibhola:
Izinzuzo: Ukungqubuzana kokuqala okuphansi, ukungqubuzana okusebenza kahle, okukwazi ukumelana nemithwalo ehlanganisiwe ye-radial kanye ne-axial, okungazweli ukuphazamiseka kokugcotshwa, okulula ukuqala emazingeni okushisa aphansi .
Okubi: Ukumelana nokushaqeka okubi, ukuvuleka okukhulu kwe-radial, okungase kubangele ukudlidliza okukhulu nomsindo.
Ukuthwala ama-roller:
Izinzuzo: Umthamo wokuthwala oqinile, ukunemba okuphezulu kokusebenza, isakhiwo esincane, izindleko eziphansi.
Okubi: Ukumelana nokushayisana okubi, isikhathi sokuphila esinciphile ngaphansi kwezimo zesivinini esikhulu kanye nomthwalo osindayo, izindandatho zangaphakathi nezangaphandle ezihlanganisiwe, kunzima ukuzifaka.
Izimo zohlelo lokusebenza
Ama-ball bearing:
Ifanele izinhlelo zokusebenza ezidinga isivinini esikhulu, umthwalo omncane kanye nokonga kahle, njengezinjini, amafeni, njll.
Ama-roller bearings:
Ifanele izinhlelo zokusebenza ezinejubane eliphansi lokujikeleza, imithwalo emikhulu noma imithwalo yokushaya, njengemishini esindayo, izimoto, ezokuthutha ngesitimela, njll.
Enamandla okuthwala umthwalo aphezulu, ama-ball bearings noma ama-roller bearings？
Ngokuphathelene nokusebenza kokuthwala umthwalo, kunomehluko omkhulu phakathi kwama-roller bearings nama-ball bearings. Ama-roller bearings, anesakhiwo sawo esiqinile esakhiwe ngamasongo angaphakathi, amasongo angaphandle, ama-roller kanye namakheji, abonisa amandla avelele okuthwala umthwalo. Asebenza kahle kakhulu ngaphansi kwemithwalo ye-radial ephezulu kanye nemithwalo ye-radial elula kuya kwephakathi, okwenza abe ukukhetha okuhle kwemishini nemishini esindayo nesindayo kakhulu, njengemishini esindayo, imishini yokwakha kanye nama-gearbox amakhulu. Ngokuphambene nalokho, yize ama-ball bearings enesakhiwo esilula, ukunemba okuphezulu kanye nokungqubuzana okuphansi, amandla awo okuthwala umthwalo aphansi kancane futhi afaneleka kakhulu ezimweni zomthwalo ophakathi. Ama-ball bearings afaka izinhlobo ezahlukene ezifana nama-deep groove ball bearings, ama-angular contact ball bearings kanye nama-self-aligning ball bearings, ngalinye lifanele imishini enezidingo ezahlukene zesivinini kanye nomthwalo. Ngakho-ke, lapho ukhetha uhlobo lokuthwala, kufanele kucatshangelwe kabanzi ngokusekelwe ezimweni ezithile zomthwalo kanye nendawo yokusetshenziswa kwemishini yomshini. Ama-roller bearings afaneleka kakhulu ukumelana nemithwalo ye-radial emikhulu kanye nesindayo, kuyilapho ama-ball bearings esebenza kangcono ngaphansi kwemithwalo ephakathi.
Yiziphi izinzuzo kanye nokungalungi kwama-roller bearings nama-ball bearings?
Ama-roller bearings nama-ball bearings ngalinye linezinzuzo nezinkinga zalo. Ama-roller bearings anendawo enkulu yokuxhumana nemigwaqo yomjaho ngoba izinto ezigoqayo ziyindilinga, eziwenza akwazi ukumelana nemithwalo emikhulu yemisebe. Aphinde abe nokuzinza okuhle nokuqina ngesikhathi sokusebenza ngesivinini esikhulu, kodwa i-friction coefficient yawo inkulu kakhulu. Izinto ezigoqayo zama-ball bearings ziyindilinga, zine-friction coefficient ephansi kanye nokusebenza okuguquguqukayo. Zifanele izinhlelo zokusebenza ezidinga ukunemba okuphezulu kanye nokusebenza ngesivinini esikhulu. Kodwa-ke, uma zithwalwa imithwalo esindayo, zingase zibangele ukuthintana okungazinzile ngenxa yomphumela wamandla e-centrifugal. Uhlobo luni lwe-bearings okufanele lukhethwe ngokukhethekile lusaxhomeke esimweni sakho sangempela sesicelo kanye nezidingo.
Yikuphi okufaneleka kakhulu ekusebenzeni ngesivinini esikhulu, ama-roller bearings noma ama-ball bearings?
Ama-roller bearings avame ukufaneleka kakhulu ekusebenzeni ngesivinini esikhulu. Ama-roller bearings anezinto ezigoqayo ezisilinda, okuholela endaweni enkulu yokuxhumana nemigwaqo yomjaho. Angamelana nemithwalo esindayo futhi abe nokuqina okuhle ngesikhathi sokusebenza ngesivinini esikhulu. Izinto ezigoqayo zama-ball bearings ziyindilinga. Nakuba i-coefficient of friction incane kakhulu, ngesikhathi sokusebenza ngesivinini esikhulu, ukuxhumana phakathi kwamabhola nemigwaqo yomjaho kungase kungazinzile ngenxa yomphumela wamandla e-centrifugal. Vele, ukukhetha okuqondile kwe-bearings okufanele uzisebenzise kusadingeka kunqunywe ngokusekelwe esimweni sakho sangempela sesicelo kanye nezidingo.
