Isantya esijikelezayo sokuthwala sidlala indima ephambili kwindawo yokufudumala yokuthwala.Imodeli nganye yokuthwala inesantya sayo somda, esinqunywe yimpawu zomzimba ezifana nobukhulu, uhlobo kunye nesakhiwo.Isantya somda sibhekisa kwisantya esiphezulu sokusebenza sokuthwala ( Ngokuqhelekileyo kusetyenziswa r / min), ngaphaya kwalo mda kuya kubangela ukunyuka kweqondo lokushisa, i-lubricant yomile, kwaye i-bearing ibambelele.Uluhlu lwezantya ezifunekayo kwisicelo luya kunceda ukugqiba ukuba loluphi uhlobo lokuthwala olunokusetyenziswa.Uninzi lweekhathalogu zabavelisi ezithweleyo zibonelela ngamaxabiso aqingqiweyo kwiimveliso zabo.Kubonakaliswe ukuba ukusebenza kumaqondo okushisa angaphantsi kwe-90% yesantya somda kungcono.

Ukujonga kwiimfuno zesantya sokusebenza kwi-bearing, xelela wonke umntu oku kulandelayo:

1. Iibhola zebhola zinesantya esiphezulu somda kunye nokuchaneka kokujikeleza kuneebheringi ze-roller, ngoko ke iibhola zebhola kufuneka zikhethwe xa zihamba ngesantya esiphezulu.

2. Ngaphantsi kwe-diameter efanayo yangaphakathi, i-diameter yangaphandle encinci, encinci i-element rolling, kunye ne-centrifugal inertia force ye-rolling element kwi-raceway yangaphandle ngexesha lokusebenza, ngoko ifanelekile ukusebenza ngesantya esiphezulu..Ngoko ke, ngesantya esiphezulu, iibheringi ezinobubanzi obuncinane bangaphandle kuluhlu olufanayo lwedayamitha kufuneka zisetyenziswe.Ukuba i-bearing ene-diameter yangaphandle encinci isetyenzisiweyo kwaye umthamo wokuthwala akwanele, ukuthwala okufanayo kunokufakwa kunye okanye uluhlu olubanzi lweebheringi lunokuqwalaselwa.

3. Izinto eziphathekayo kunye nesakhiwo se-cage sinempembelelo enkulu kwisantya sokuthwala.I-cage eqinile ivumela isantya esiphezulu kune-cage enesitampu, kunye ne-bronze cage eqinile ivumela isantya esiphezulu.

Ngokuqhelekileyo, kwimeko yokusebenza kwesantya esiphezulu, iibhola zebhola ze-groove ezinzulu, ii-angular contact bearings kunye ne-cylindrical roller bearings kufuneka zisetyenziswe;kwimeko yokusebenza kwesantya esisezantsi, iibheringi ze-tapered roller zingasetyenziswa.Isantya esisikelweyo seebheringi ezine-tapered roller ngokuqhelekileyo simalunga ne-65% yeebheringi zebhola ezinzulu, i-70% yeebheringi ze-cylindrical roller, kunye ne-60% yeebheringi zeebhola zokudibana.Iibheringi zebhola zethrust zinesantya esisezantsi kwaye zinokusetyenziswa kuphela kwizicelo zesantya esisezantsi.
