PNA12/28 Sib Nqus rab koob rau cov menyuam bearings, nrog lub nplhaib puab
Kev sib tw koob rau cov menyuam bearings muaj ib lub nplhaib sab nraud nrog ib tug kheej kheej sab nraud. Ob lub rooj zaum polymer nrog lub sphered nyob rau hauv qhov chaw yog encased nyob rau hauv ib tug kos daim ntawv hlau lub tes tsho thiab haum tshaj lub nplhaib txheej.Qhov no tsim enables cov bearings kom haum zoo li qub misalignment ntawm tus ncej txheeb ze rau lub vaj tse.Nyob rau hauv daim ntawv thov qhov twg lub ncej yuav hardened thiab hauv av, bearings nrog lub nplhaib puab yuav tsum tau siv. Qhov tso cai axial hloov chaw ntawm tus ncej txheeb ze rau lub tsev yog txwv rau cov bearings nrog lub nplhaib puab. Yog hais tias qhov tso cai axial hloov chaw muab los ntawm tus qauv puab lub nplhaib tsis txaus, nws tuaj yeem siv lub nplhaib sab hauv txuas ntxiv.
Cov kabmob uas tsis muaj lub nplhaib sab hauv yog qhov kev xaiv zoo tshaj plaws rau kev sib cog kabmob, yog tias cov ncej tuaj yeem ua kom tawv thiab hauv av.
Cov yam ntxwv ntawm PNA12/28 Alignment koob rau cov menyuam bearings
Ua kom zoo li qub misalignment: Kev sib tw koob rau cov menyuam bearings yog tus kheej-aligning mus txog 3 ° ntawm static misalignment.
Tsawg hla ntu: Hauv cov ntawv thov uas muaj qhov chaw tsawg, kev sib haum xeeb koob cov menyuam bearings muab cov kev daws teeb meem.
Lub peev xwm nqa tau siab: Vim lawv cov menyuam coob coob, kev sib tw koob cov menyuam bearings muaj peev xwm nqa tau siab.
