Kukho izinto ezi-6 ekufuneka ziqwalaselwe xa ukhetha iibheringi zezixhobo zokukhenkcisa

 

Zonke iintlobo zeebheringi eziqengqelekayo zineempawu ezahlukeneyo kwaye zifanelekile kwiimeko ezahlukeneyo zokusetyenziswa koomatshini abahlukeneyo. Phantsi kweemeko eziqhelekileyo,iibheringi zokutyhala kunye neebheringi zoqhagamshelwano ze-angularzikhethwa xa zithwala imithwalo yokutyhala;

 

Iibheringi zebholazihlala zisetyenziselwa usetyenziso olukhawulezayo, kwaye ii-roller bearings zisetyenziselwa imithwalo enzima ye-radial.

 

1. Indawo kunye nendawo yoomatshini abasetyenziswa yiibhereyitha

 

Kuyilo loomatshini, ubukhulu bomngxuma bumiselwa kuqala, uze emva koko i-rolling bearing ikhethwe ngokobukhulu bomngxuma. Ii-ball bearing zihlala zisetyenziselwa ii-shafts ezincinci kunye nee-roller bearings zee-shafts ezinkulu. Nangona kunjalo, xa i-bearing ilinganiselwe kwicala lobubanzi bomatshini,iibheringi zerola yenaliti, iibheringi zebhola okanye zerola zoluhlu lokukhanya okungaphezulu kunye noluhlu lokukhanya okuphezulu ziyakhethwa; Xa indawo ye-axial yebheringi kumatshini ithintelwe, uthotho oluncinci okanye oluncinci kakhulu lweebheringi zebhola okanye zerola ziyafumaneka.

 

2. Ubukhulu, indlela kunye nohlobo lomthwalo okwibheri

 

Umthwalo yeyona nto ibalulekileyo ekukhetheni iibheringi. Iibheringi zerola zisetyenziselwa ukumelana nemithwalo enzima, iibheringi zebhola zisetyenziselwa ukumelana nemithwalo elula okanye ephakathi, kwaye iibheringi ezenziwe ngentsimbi ekhabhoriziweyo okanye ezicinyiweyo ze-bainite zenzelwe ukumelana nemithwalo yokothuka kunye nokungcangcazela.

 

Ngokuphathelele indlela esebenza ngayo umthwalo, xa uthwele imithwalo yeradial ecocekileyo, iibheringi zebhola ezinzulu, iibheringi zerola ezisilinda okanye iibheringi zerola yeenaliti zingakhethwa. Xa uthwele imithwalo emincinci ye-axial ecocekileyo, iibheringi zebhola ezithululwayo zingakhethwa; Iibheringi zerola ezithululwayo ziyafumaneka kwimithwalo emikhulu ye-axial ecocekileyo. Xa ibheringi iphantsi komthwalo weradial odibeneyo kunye nomthwalo we-axial, iibheringi zebhola ezinxibelelanayo ze-angular okanye iibheringi zerola ezithambileyo zihlala zisetyenziswa.

 

3.Ukusebenza kokuzilungisa kwebhereyitha

 

Xa umgca ophakathi weshaft wahlukile kumgca ophakathi wendlu yeebheringi, kukho impazamo ye-angular, okanye ngenxa yokuba isithuba phakathi kwezixhaso ezimbini zeshaft sikhulu kwaye ukuqina kweshaft kuncinci, kulula ukugoba okanye ukuthambeka phantsi kwamandla, ibhola elizilungelelanisayo okanye i-roller bearing ezizilungelelanisayo esebenza kakuhle kunye ne-ball bearing yangaphandle inokukhethwa. Ezi bearing zihlala zisebenza ngendlela eqhelekileyo xa i-shaft ithambekile okanye igobile kancinci.

 

Umgangatho wokusebenza kwe-bearing self-alignment unxulumene ne-axiality eyahlukileyo evumelayo, kwaye okukhona ixabiso le-axiality eyahlukileyo lilikhulu, kokukhona ukusebenza kwe-self-alignment kungcono.

 

4. Ukuqina kwebhereyitha

 

Ukuqina kwebheri kubhekisa kubungakanani bamandla afunekayo ukuze ibheri ivelise ukuguquguquka kweyunithi. Ukuguquguquka kwe-elastic kweebheri eziqengqelekayo kuncinci kakhulu, kwaye akufuneki kuqwalaselwe koomatshini abaninzi, kodwa kwezinye iimashini, ezifana nee-spindles zezixhobo zomatshini, ukuqina kweebheri yinto ebalulekileyo, kwaye iibheri ze-roller ezisilinda nezithambileyo kufuneka zikhethwe ngokubanzi. Ngenxa yokuba ezi ntlobo zimbini zeebheri zidibana ngqo nendlela yokugijima xa ziphantsi komthwalo, ukuqina kwazo akukuhle.

 

Ukongeza, zonke iintlobo zeebheringi zingalayishwa kwangaphambili ukuze kufezekiswe injongo yokwandisa ukuqina kwenkxaso. Umzekelo,iibheringi zebhola yoqhagamshelwano lwe-angularkunye neebheringi zeroller ezithambileyo, ukuze kuthintelwe ukungcangcazela komngxuma nokwandisa ukuqina kwenkxaso, amandla athile e-axial adla ngokusetyenziswa kwangaphambili ngexesha lokufakelwa ukuze acinezelwe. Kubalulekile ukuqaphela apha ukuba ubungakanani bomthwalo wangaphambi kokuba ulayishwe akufanele bube bukhulu kakhulu. Xa bukhulu kakhulu, ukungqubana kwebheriya kuya kwanda, ukunyuka kobushushu kuya kwanda, kwaye ubomi benkonzo yebheriya buya kuchaphazeleka.

 

5. Isantya sokujikeleza kwebhereyitha

 

Imodeli nganye yeebhereyitha inesantya sayo esilinganiselweyo, esimiselwa ziimpawu zomzimba ezifana nobukhulu, uhlobo kunye nolwakhiwo, isantya esilinganiselweyo sibhekisa kwisantya esiphezulu sokusebenza kwebhereyitha (ngesiqhelo i-r/min), ukudlula lo mda kuya kubangela ukuba ubushushu beebhereyitha bunyuke, i-lubricant yome, kwaye yenze nebhereyitha ibambeke. Uluhlu lwesantya olufunekayo kwisicelo lunceda ekumiseleni ukuba loluphi uhlobo lweebhereyitha ekufuneka lusetyenziswe. Uninzi lwabavelisi beebhereyitha lubonelela ngexabiso lokugqibela lesantya seemveliso zabo kwiikhathalogu zemveliso yabo, kwaye indlela yokusebenza iye yabonisa ukuba kungcono ukusebenza kwimeko engaphantsi kwe-90% yesantya esilinganiselweyo.

 

Ngokubanzi, xa usebenza ngesantya esiphezulu, kuyacetyiswa ukuba ukhethe ii-deep groove ball bearings, ii-angular contact bearings, kunye nee-cylindrical roller bearings; Kwisantya esiphantsi, ii-tapered roller bearings azinyanzelekanga. Isantya esiphezulu see-tapered roller bearings sidla ngokuba malunga ne-65% yeso see-deep groove ball bearings, i-70% yee-cylindrical roller bearings, kunye ne-60% yee-angular contact ball bearings. Ii-Thrust ball bearings zinesantya esiphantsi kwaye zingasetyenziswa kuphela ngesantya esiphantsi.

 

6. Ilungele ukufakwa kunye nokuqhekeka kweebheringi

 

Xa ukhetha uhlobo lwebheriya, kuyimfuneko ukuqwalasela ukuba ingaba ibheriya ilungele ukuyifaka nokuyiqhekeza, ingakumbi ekufakelweni nasekuqhawulweni kweebheriya ezinkulu nezinkulu kakhulu. Iibheringi zebhola zoqhagamshelwano ezijikelezileyo, iibheringi zerola ezithambileyo, iibheringi zerola ezisilinda kunye neebheringi zerola yeenaliti ezineendandatho zangaphandle ezahlulweyo kulula ukuzifaka nokuziqhekeza, kwaye iindandatho zazo zangaphakathi nezangaphandle zinokufakwa kwishaft okanye kwibhore yendlu ngokulandelelana. Ukongeza, iibheringi zerola ezisilinda ezinebhore ezisilinda kunye nesleeve yeadaptha, iibheringi zerola ezisilinda eziphindwe kabini kunye neebheringi zebhola ezisilinda kulula ukuzifaka nokuziqhekeza.
