1. Izinga lokubekezelelana lokuthwala linqunywa ngokuvumelana nemfuneko yokunemba kokujikeleza kokusekelwa kwe-axial.
Izinga 0: isetshenziswa kabanzi ezinhlelweni ezithwalayo ezijwayelekile ezinonemba ozungezayo ezingaphezu kuka-10 m.Njengendlela yokushintsha isivinini yethuluzi lomshini ojwayelekile, umshini wokushintsha isivinini wendlela yokudla, imoto, ugandaganda, injini evamile, iphampu yamanzi kanye nemishini yezolimo. , njll.
Izinga 6, 5, ekunembeni okujikelezayo kuma-microns angu-5 kuya kwayi-10 noma isistimu yokunemba enesivinini esiphezulu, njengamabheringi ajwayelekile asetshenzisiwe (ukusekelwa okungaphambili okunamazinga angu-5, izinga lokusekela 6) ngemva kwezinsimbi ezinembayo, amamitha namathuluzi anembayo, amamitha, kanye nokunemba komshini ojikelezayo.
Izinga 4,2: ngokunemba okujikelezayo okungaphansi kwama-microns angu-5 noma kumathuluzi anembayo aphezulu anesivinini esikhulu, njengomshini oyisicefe wokuhlanganisa ukunemba, umshini wokugaya oqondile wesistimu yegiya, izinsimbi ezinembayo, amamitha namakhamera anesivinini esikhulu nokunye ukunemba uhlelo.
2. I-Chinese bearing isetshenziselwa ukuqokwa kwebanga lokunemba.
Amazinga abekwe izwe ngalinye akhiwe ngokuvumelana nezindinganiso ze-ISO, futhi ngokuvamile ahambisana namazinga e-ISO.Ukunemba kuhlukaniswe ngokunemba kobukhulu nokunemba kokuzungezisa.Ihlukaniswe yaba ngu-0, 6X, 6, 5, 4 kanye no-2.
Amakhodi amadala ebheringi yesiShayina asetshenziswayo yilawa:G (0), E (6), D (5), C (4), kanye no-B (2). Ikhodi yamanje ivamise ukutholwa yindinganiso yesiJalimane ye-DIN.
I-P0 (izinga 0), i-P6 (izinga lesi-6), i-P5 (izinga lesi-5), i-P4 (izinga lesi-4), izinga lesi-2 (izinga lesi-2).
Ibanga elijwayelekile le-P0 elijwayelekile, ukusabela ku-elliptical kumodeli ephethe, izinga le-P6 noma le-P6 kuphela, ikhodi yebanga ivela kumodeli ephethe.
Isibonelo: 6205 kanye no-6205/P5, okuthi i-6205 ineleveli yokunemba engu-P0, kodwa iyeqiwa.Lokhu kunikeza abantu umbono wokuthi ikilasi le-P0 alinakho ukunemba kwebanga.
Ngaphezu kwalokho, ama-bearings azo zonke izinhlobo zokunemba ahlukile ekucubunguleni ubuchwepheshe, futhi ahlukile ngenani.Ngokwesibonelo, inani lomkhiqizo odumile e-China, ukunemba kwe-P6 ukunemba izikhathi eziyi-1.5 ze-P0, kanye nokunemba kwe-P5 ngokunemba. iphakeme kabili kune-P0, futhi ukunemba kwe-P4 izikhathi ezingu-2.5 ze-P5.
