Kunezici ezi-6 okufanele uzicabangele lapho ukhetha ama-bearings emishini yokuqandisa

 

Zonke izinhlobo zama-rolling bearings zinezici ezahlukene futhi zifaneleka ezimweni ezahlukene zokusetshenziswa kwemishini ehlukahlukene. Ngaphansi kwezimo ezijwayelekile,amabheringi okusunduza kanye namabheringi okuxhumana angularzikhethwa lapho kuthwala imithwalo yokusunduza;

 

Ama-ball bearingsngokuvamile asetshenziselwa izinhlelo zokusebenza zesivinini esikhulu, kanti ama-roller bearings asetshenziselwa imithwalo esindayo ye-radial.

 

1. Isikhala nendawo yemishini esetshenziswa yi-ibhere

 

Ekwakhiweni kwemishini, ubukhulu bomgodi buvame ukunqunywa kuqala, bese kuba yi-rolling bearing ekhethwa ngokuya ngobukhulu bomgodi. Ama-ball bearing avame ukusetshenziselwa ama-shaft amancane nama-roller bearing kuma-shaft amakhulu. Kodwa-ke, lapho i-bearing inqunyelwe ohlangothini lobubanzi bomshini,amabheringi e-needle roller, ama-bearings ebhola noma ama-roller ochungechunge lokukhanya okwengeziwe kanye nokukhanya okukhulu kuyakhethwa; Uma indawo ye-axial ye-bearings emshinini inqunyelwe, uchungechunge oluncane noma oluncane kakhulu lwama-bearings ebhola noma ama-roller luyatholakala.

 

2. Ubukhulu, isiqondiso kanye nohlobo lomthwalo obhekwe

 

Umthwalo uyisici esibaluleke kakhulu ekukhetheni ama-bearings. Ama-roller bearings asetshenziselwa ukumelana nemithwalo esindayo, ama-ball bearings asetshenziselwa ukumelana nemithwalo elula noma ephakathi, kanti ama-bearings enziwe ngensimbi ekhabhoni noma i-bainite ecinyiwe aklanyelwe ukumelana nemithwalo yokushaqeka nokudlidliza.

 

Ngokuya ngendlela umthwalo osebenza ngayo, lapho uthwala imithwalo ye-radial emsulwa, ama-bearings ebhola e-groove ejulile, ama-bearings e-roller ayisilinda noma ama-bearings e-roller anenaliti angakhethwa. Uma uthwala imithwalo emincane ye-axial emsulwa, ama-bearings e-thrust ball angakhethwa; Ama-bearings e-Thrust roller ayatholakala emithwalweni emikhulu ye-axial emsulwa. Lapho i-bearing ibhekene nomthwalo we-radial ohlanganisiwe kanye ne-axial, ama-bearings e-angular contact ball noma ama-bearings e-roller aqoshiwe ngokuvamile asetshenziswa.

 

3.Ukusebenza kokuzivumelanisa kwebhereyi

 

Uma umugqa ophakathi womgodi uhlukile kumugqa ophakathi wendlu yokuthwala, kuba nephutha le-angular, noma ngoba isikhala phakathi kwezisekelo ezimbili zomgodi sikhulu futhi ukuqina komgodi kuncane, kulula ukugoba noma ukuthambekela ngaphansi kwamandla, ibhola eliziqondisayo noma i-roller bearing eziqondisayo esebenza kahle ngokuziqondisa kanye ne-ball bearing yangaphandle ingakhethwa. Lawa ma-bearing ahlala esebenza ngokujwayelekile lapho i-shaft ithambekile noma igobile kancane.

 

Ikhwalithi yokusebenza kokuzivumelanisa kwebhere ihlobene nokuma okuhlukile okuvumelayo, futhi lapho inani lokuma okuhlukile likhula, kulapho ukusebenza kokuzivumelanisa kuthuthuka khona.

 

4. Ukuqina kwebhereyi

 

Ukuqina kwebheri kubhekisela enanini lamandla adingekayo ukuze ibheri ikhiqize ukuguqulwa kweyunithi. Ukuguquguquka okunwebekayo kwamabheri ajikelezayo kuncane kakhulu, futhi akudingekile ukukucabangela emishinini eminingi, kodwa kweminye imishini, njenge-spindles yamathuluzi omshini, ukuqina kwamabheri kuyisici esibalulekile, futhi amabheri ajikelezayo asindilinga nathambile kufanele akhethwe ngokuvamile. Ngenxa yokuthi lezi zinhlobo ezimbili zamabheri zithintana ngqo nomgwaqo lapho zingaphansi komthwalo, ukuqina akukuhle.

 

Ngaphezu kwalokho, zonke izinhlobo zama-bearings nazo zingalayishwa kusengaphambili ukuze kufezwe injongo yokwandisa ukuqina kokusekelwa. Isibonelo,amabheringi ebhola lokuxhumana eliyi-angularkanye nama-roller bearings athambile, ukuze kuvinjelwe ukudlidliza komgodi futhi kwandiswe ukuqina kokusekelwa, amandla athile e-axial avame ukusetshenziswa kusenesikhathi ngesikhathi sokufakwa ukuze acindezelane. Kubalulekile ukuqaphela lapha ukuthi inani lokulayisha kusengaphambili akufanele libe likhulu kakhulu. Uma likhulu kakhulu, ukungqubuzana kwebhereyi kuzokwanda, ukwenyuka kwezinga lokushisa kuzokwanda, futhi impilo yenkonzo yebhereyi izothinteka.

 

5. Ijubane lokujikeleza kwebhereyitha

 

Imodeli ngayinye yokuthwala inesivinini sayo esinqunyiwe, esinqunywa izici zomzimba ezifana nosayizi, uhlobo kanye nesakhiwo, isivinini esinqunyiwe sibhekisela esivinini esiphezulu sokusebenza se-bearing (ngokuvamile i-r/min), ukudlula lo mkhawulo kuzokwenza izinga lokushisa le-bearing likhuphuke, i-lubricant yome, futhi yenze i-bearing ibambeke. Ububanzi besivinini obudingekayo ekusetshenzisweni kusiza ekunqumeni ukuthi hlobo luni lwe-bearing okufanele lusetshenziswe. Abakhiqizi abaningi be-bearing banikeza inani lesivinini esiphezulu semikhiqizo yabo kumakhathalogi abo emikhiqizo, futhi umkhuba ukhombisile ukuthi kungcono ukusebenza esimweni esingaphansi kwama-90% wesivinini esinqunyiwe.

 

Ngokuvamile, ngesikhathi sokusebenza sejubane eliphezulu, kuyalulekwa ukukhetha ama-deep groove ball bearings, ama-angular contact bearings, nama-cylindrical roller bearings; Ngejubane eliphansi, ama-tapered roller bearings ayazikhethela. Ijubane lokugcina lama-tapered roller bearings ngokuvamile licishe libe ngu-65% wale lama-deep groove ball bearings, ama-70% ama-cylindrical roller bearings, kanye nama-60% ama-angular contact ball bearings. Ama-thrust ball bearings anejubane eliphansi lomkhawulo futhi angasetshenziswa kuphela ngejubane eliphansi.

 

6. Kulula ukufakwa nokuhlukaniswa kwama-bearings

 

Uma ukhetha uhlobo lwe-bearing, kubalulekile futhi ukucabangela ukuthi i-bearing ilula yini ukuyifaka nokuyihlukanisa, ikakhulukazi ekufakweni nasekuhlukaniseni ama-bearing amakhulu namakhulu kakhulu. Ama-bearing ajwayelekile e-angular contact ball, ama-bearing a-tapered roller, ama-bearing a-cylindrical roller kanye nama-bearing a-needle roller anezindandatho zangaphandle ezihlukanisiwe kulula ukuwafaka nokuwahlukanisa, futhi izindandatho zawo zangaphakathi nezangaphandle zingafakwa ku-shaft noma ku-housing bore ngokulandelana. Ngaphezu kwalokho, ama-bearing a-spherical roller ane-bore e-tapered kanye ne-adapter sleeve, ama-bearing a-cylindrical roller anemigqa emibili kanye nama-bearing a-spherical ball kulula ukuwafaka nokuwahlukanisa.
