Ukuqina kokuthwala ngamandla afunekayo ukwenza i-deformation deformation.I-elastic deformation ye-rolling bearings incinci kakhulu kwaye inokungahoywa koomatshini abaninzi.Nangona kunjalo, kwabanye oomatshini, abanje ngeespindles zesixhobo somatshini, ukuthwala ukuqina yinto ebalulekileyo.Iibheringi ze-Cylindrical kunye ne-tapered roller zisetyenziswa ngokubanzi.Ngenxa yokuba iindidi ezimbini zeebherethi ziphantsi komthwalo, izinto ezijikelezayo kunye neendlela zokugijima zihambelana nomgca, kwaye i-deformation elastic incinci kwaye ukuqina kulungile.Zonke iintlobo zeebheringi nazo zinokuqiniswa kwangaphambili ukunyusa ukuqina kwenkxaso.Ngokomzekelo, iibherethi zebhola zoqhagamshelwano kunye ne-tapered roller bearings, ukwenzela ukuthintela ukuxubha kwe-shaft kunye nokwandisa ukuqina kwenkxaso, i-axial force ethile idla ngokusetyenziswa ngexesha lofakelo ukuze ucinezele omnye komnye.Ngokuqinisekileyo, isixa sangaphambili sokuqina akufanele sibe sikhulu kakhulu.Ukuba kukhulu kakhulu, ukungqubuzana okuthwala kuya kwanda kwaye ukunyuka kweqondo lokushisa kuya kwanda, okuya kuchaphazela ubomi benkonzo yokuthwala.
