Amapharamitha wokukhetha okuzalayo

Isikhala esivumelekile sokufaka i-Bearing
Ukufaka i-bearing empahleni eqondiwe, indawo evumelekile yebheringi eginqikayo kanye nezingxenye zayo eziseduze ngokuvamile zikhawulelwe ngakho-ke uhlobo nosayizi webheringi kufanele kukhethwe ngaphakathi kwemikhawulo enjalo.Ezimweni eziningi, ububanzi be-shaft bulungiswa kuqala ngesisekelo sokuqina namandla ngumklami womshini;ngakho-ke, ukuthwala kuvame ukukhethwa ngokusekelwe kusayizi wayo wokubhoboza.Kunochungechunge oluningi olujwayelekile lwe-dimension kanye nezinhlobo ezitholakalayo zamabheringi agingqikayo futhi ukukhethwa kwe-bearing engcono kakhulu kuwo kuwumsebenzi obalulekile.

Izinhlobo Zomthwalo Nokuthwala
Ubukhulu bomthwalo, uhlobo kanye nesiqondiso somthwalo osetshenzisiwe kufanele kucatshangelwe ekukhethweni kohlobo lokuthwala.Umthamo wokuthwala umthwalo we-axial we-bearing uhlobene eduze nomthamo womthwalo we-radial ngendlela encike kumklamo wokuthwala.

Isivinini Esivumelekile Nezinhlobo Zokuthwala
Amabhorethi azokhethwa ngokuphendula isivinini sokujikeleza semishini lapho kuzofakwa khona ama-abheri;ijubane elikhulu lama-rolling bearings liyahlukahluka kuye ngokuthi, hhayi kuphela uhlobo lokuthwala, kodwa futhi nobukhulu balo, uhlobo lwekheji, imithwalo ohlelweni, indlela yokugcoba, ukuchithwa kokushisa, njll. Uma kucatshangwa ukuthi indlela evamile yokugcoba amafutha okugeza, izinhlobo ezithwala cishe zibalwa kusukela ngesivinini esikhulu ukuya ngaphansi.

Ukungaboni ngaso linye Kwezindandatho Zangaphakathi/Zangaphandle Nezinhlobo Zokuthwala
Amasongo angaphakathi nangaphandle awaqondani kahle kancane ngenxa yokuchezuka kwe-shaft okubangelwa imithwalo esetshenzisiwe, iphutha le-dimensional le-shaft nezindlu, namaphutha okukhweza.Inani elivunyelwe lokungaboni ngaso linye liyahlukahluka kuye ngohlobo lokuthwala nezimo zokusebenza, kodwa ngokuvamile liyi-engeli encane engaphansi kuka-0.0012 radian.Uma kulindelekile ukungahambi kahle okukhulu, ama-bearings anekhono lokuziqondanisa, njengama-self-aligning ball bearings, ama-rollers ayindilinga namayunithi okuthwala kufanele kukhethwe.

Ukuqina kanye Nezinhlobo Zokuthwala
Lapho imithwalo ibekwa ku-rolling bear, okunye ukuguqulwa kwe-elastic kwenzeka ezindaweni zokuthintana phakathi kwezinto ezigoqayo kanye nemigwaqo yomjaho.Ukuqina kokuthwala kunqunywa isilinganiso somthwalo othwala inani le-deformation enwebekayo yamasongo angaphakathi nangaphandle kanye nezakhi ezigoqayo.Ukuphakama kokuqina kwebhere, kungcono ukulawula ukuwohloka kwe-elastic.Kuma-spindle ayinhloko amathuluzi omshini, kuyadingeka ukuba nokuqina okuphezulu kwama-bearings kanye nokunye okuphothayo.Ngakho-ke, njengoba ama-roller bearings ekhubazekile kancane ngomthwalo, avame ukukhethwa kunamabhola.Lapho kudingeka ukuqina okuphakeme okwengeziwe, kuthwala imvume engalungile.Ama-angular contact ball bearings nama-roller ama-tapered avame ukulayishwa kuqala.
