Izici ● Ibhola le-angular contact ball bearing kanye nomjaho weringi yangaphakathi nendandatho yangaphandle ingathintana nge-engeli endaweni yeradial.Uma isetshenziswe yodwa, umthwalo we-axial unqunyelwe isiqondiso esisodwa, futhi ufanelekile umthwalo ohlangene we-axial load kanye nomthwalo we-radial.● Ngenxa yokuthi leli bhili line-engeli yokuxhumana, ingxenye yamandla e-axial iyakhiqizwa lapho ukulayisha kwe-radial kusebenza.Ngakho-ke, ngokuvamile isetshenziswa ngendlela ye-symmetry noma ukubhanqa ezinhlangothini zombili ze-shaft.● Kukhona futhi izinhlobo ezisebenzisa amabhola e-ceramic.I-engeli yokuxhumana Kunezinhlobo ezimbili ze-engeli yokuxhumana, 15° kanye no-25°.I-15° isetshenziselwa izinhlelo zokusebenza ezinesivinini esikhulu.I-25° ifanele izikhathi lapho kudingeka khona ukuqina kwe-axial.Ikheji lenziwe nge-polyamide njengokujwayelekile.Sicela usebenzise ikheji ye-polyamide engaphansi kuka-120°.Ukunemba kobukhulu nokunemba kokujikeleza kuvumelana nekilasi le-JIS lesi-5 noma lesi-4. Sicela ubhekisele ekhasini 7. Layisha kusengaphambili ● Setha izinhlobo ezi-4 zenani elijwayelekile lokulayisha kuqala.Khetha ukulayisha kuqala okufunayo ngokusekelwe kumbandela wokukhetha kuthebula elingakwesokudla.● Bheka amakhasi 16 kuya ku-18 ukuze uthole inani elijwayelekile lokulayisha kuqala ochungechungeni ngalunye nosayizi.

Ukuhlanganisa Ukuze usebenzise ukuhlanganiswa kwamakholomu amaningi, sicela ubheke amakhasi 12 kuya ku-13. Uhlobo lwebhola le-Ceramic Ukuze unciphise amandla ebhola aphakathi nendawo ngesikhathi sokuzungezisa ngesivinini esikhulu, kusetshenziswa ibhola le-ceramic elinobukhulu obuphansi kunensimbi ethwalayo.● Bheka ithebula elingezansi ukuze uthole izici ezihlukahlukene zezitsha zobumba nezinsimbi ezithwalayo.● Engeza okuthi “SH6-” ekuqaleni kwenombolo yemodeli yamabheringi usebenzisa amabhola e-ceramic.● Ukulayisha kuqala kanye ne-axial rigidity cishe izikhathi ezingu-1.2 zohlobo lwebhola lensimbi elithwele.Layisha kusengaphambilini izinga lokukhetha uphawu elingu-E (ukulayisha kuqala okuncane) Vimbela ukudlidliza komshini futhi uthuthukise ukunemba L (ukulayisha kuqala ukukhanya) Isivinini esikhulu (inani le-dmn elingu-500,000) sisenokuqina okuthile okungu-M (ukulayisha kuqala okumaphakathi) Isizukulwane silula kunejubane elijwayelekile I-Rigidity H enezinga eliphezulu ukulayisha kuqala (ukulayisha kuqala) kukhiqiza ukuqina okukhulu ngesivinini esiphansi.
