Iiparamitha zokukhetha ukuthwala

Indawo yofakelo oluvunyiweyo
Ukufakela i-bearing kwisixhobo esijoliswe kuyo, indawo evumelekileyo ye-rolling bearing kunye neendawo zayo ezikufutshane ngokubanzi zilinganiselwe ngoko ke uhlobo kunye nobukhulu bokuthwala kufuneka kukhethwe phakathi kwemida enjalo.Kwiimeko ezininzi, i-shaft diameter igxininiswe kuqala ngesiseko sokuqina kwayo kunye namandla ngumyili womatshini;ngoko ke, ukuthwala kudla ngokukhethwa ngokusekelwe kubungakanani bayo.Kukho uluhlu oluninzi olusemgangathweni olusemgangathweni kunye neentlobo ezifumanekayo zokuqengqeleka kweebheringi kunye nokukhethwa kweyona nto iphezulu kubo ngumsebenzi obalulekileyo.

Iintlobo zomthwalo kunye nokuthwala
Ubungakanani bomthwalo, uhlobo kunye nesikhokelo somthwalo osetyenzisiweyo kufuneka kuthathelwe ingqalelo ekukhethweni kohlobo lokuthwala.Umthamo wokuthwala umthwalo we-axial wokuthwala unxulumene ngokusondeleyo nomthamo womthwalo we-radial ngendlela exhomekeke kuyilo lokuthwala.

Isantya esivumelekileyo kunye neentlobo zokuthwala
Iibheringi eziza kukhethwa ngokuphendula kwisantya sokujikeleza kwesixhobo apho ukuthwala kuya kufakwa khona;Isantya esiphezulu seebheringi eziqengqelekayo siyahluka ngokuxhomekeka, kungekhona kuphela uhlobo lokuthwala, kodwa kunye nobukhulu bayo, uhlobo lwekheji, imithwalo kwinkqubo, indlela yokuthambisa, ukutshatyalaliswa kobushushu, njl. zibalwa ukusuka kwisantya esiphezulu ukuya esisezantsi.

Ukungahambi kakuhle kweeNdandatho zangaphakathi / zangaphandle kunye neentlobo zokuBheja
Amakhonkco angaphakathi nangaphandle abonakaliswe kakubi ngenxa yokuphambuka kwe-shaft ebangelwa yimithwalo esetyenzisiweyo, impazamo ye-dimensional ye-shaft kunye nezindlu, kunye neempazamo ezikhulayo.Isixa esivumelekileyo sokungahambi kakuhle siyahluka ngokuxhomekeke kuhlobo lokuthwala kunye neemeko zokusebenza, kodwa ngokuqhelekileyo i-angle encinci ngaphantsi kwe-0.0012 radian.Xa ulungelelwaniso olukhulu lulindeleke, iibheringi ezikwaziyo ukuzilungelelanisa, ezifana neebheringi zebhola ezizilungelelanisayo, iibheringi ezingqukuva kunye neeyunithi zokuthwala kufuneka zikhethwe.

Ubungqongqo kunye neentlobo zokuQinisekisa
Xa imithwalo ibekwe kwi-rolling bearing, i-deformation e-elastic eyenzeka kwiindawo zoqhagamshelwano phakathi kwezinto ezijikelezayo kunye ne-raceways.Ukuqina kokuthwala kunqunywe ngumlinganiselo womthwalo wokuthwala ukuya kwisixa se-elastic deformation yeendandatho zangaphakathi nangaphandle kunye nezinto ezijikelezayo.Okukhona buphezulu ubungqongqo obunayo ibherethi, ilawula ngcono i-elastic deformation.Kwimibhobho ephambili yezixhobo zoomatshini, kuyafuneka ukuba ube nokuqina okuphezulu kweebheringi kunye ne-spindle yonke.Ngenxa yoko, ekubeni iibheringi eziqengqelekayo zikhubazeke ngaphantsi komthwalo, zikhethwa ngokufuthi kuneebheringi zebhola.Xa kufuneka ukuqina okuthe kratya okuthe kratya, oku kuthwala ukucocwa okungalunganga.Iibheringi zebhola e-angular kunye neebheringi ze-tapered roller zihlala zilayishwa kwangaphambili.
