Cov ntsiab lus thiab cov ntsiab lus muaj feem xyuam nrog dov bearings
1, lub neej
Xa mus rau txheej txheej ntawm cov kabmob sib dhos uas ib lub nplhaib (lossis washer) lossis tus lej ntawm kev txhim kho ntawm ib lub nplhaib (lossis washer) txheeb ze rau lwm lub nplhaib (lossis washer) ua ntej thawj cov cim kev qaug zog kis ntawm cov khoom siv dov.
2. Kev ntseeg siab (ntawd yog kev ntseeg tau ntawm lub neej ua haujlwm)
Qhov feem pua ntawm ib pab pawg ntawm yuav luag zoo ib yam li cov dov ua hauj lwm nyob rau hauv tib lub zwj ceeb uas xav kom tau raws lossis tshaj qhov teev tseg lub neej.Qhov ntseeg tau ntawm cov kabmob dov ib qhov yog qhov tshwm sim uas cov kabmob tau ncav lossis siab dua lub neej teev tseg.
3. Zoo li qub load
Ntsaws thov rau cov kabmob thaum tus txheeb ze sib hloov ceev ntawm cov kabmob ntiv nplhaib lossis washer yog xoom (centripetal lossis thawb cov kabmob) lossis thaum cov khoom sib tw tsis txav mus rau txoj kev yob (cov kabmob tawm).
Kev siv lub zog thiab yoog
Lub nra thov rau cov kabmob thaum lub nplhaib cov kabmob lossis cov ntxhua khaub ncaws sib hloov sib hloov ua ke sib luag (cov kabmob me me lossis cov kabmob thawb tawm) lossis thaum lub txav khoom txav mus rau hauv cov kev taw qhia ntawm txoj kev sib dhos (cov kabmob tawm).
5. Ua lub neej
Lub neej kev twv ua ntej raws li radial theem pib dynamic load lossis axial theem pib dynamic load.
6. Pib ntsuas lub neej
Nyob lub neej muaj feem nrog 90% kev ntseeg tau.
7. Radial theem pib dynamic load
Hais txog ib pawg ntawm cov dov cov kev xav tau xav tias yuav tiv taus ib qho kev kho lub neej tas mus li, uas nyob rau qhov ntsuas qhov nruab nrab ntawm lub neej yog ib lab kev hloov pauv.Rau ib kab nkaus xwb angular hu rau cov kabmob, cov thauj khoom yog lub radial tivthaiv ntawm cov load uas coj kev ntshiab huv radial tawm ntawm cov kabmob cov kabmob.
8. Axial qhov ua haujlwm nyob rau qhov chaw siab dynamic load
Lub hypothetical tas mus li qhov nruab nrab axial load thov rau txoj kev sib dhos cov kabmob uas qhov pib ntsuas lub neej ntawm cov kabmob sib dhos yog ib lab kev hloov pauv.
9. Radial (lossis axial) sib npaug dynamic load
Hais txog qhov xwm yeem radial load (lossis nruab nrab axial load) nyob rau hauv uas cov kabmob dov tau muaj lub neej zoo ib yam li cov khoom thauj khoom tiag.
10. Radial (lossis axial) theem pib rated zoo li qub load
Xa mus rau radial zoo li qub load (los yog central axial zoo li qub load) sib nug mus rau tag nrho mus tas li deformation ntawm dov lub cev thiab haiv neeg.Yog hais tias, nyob rau hauv xoom load, cov menyuam thiab cov kev sib tw (cov kabmob kev sib tw) yog lossis xav tias yog lub tsheb npav ib txwm (tag nrho cov kab sib tiv tauj), hauv qab kev sib tiv toj siab tshaj plaws, qhov kev hloov kho tas mus li ntawm kev sib cuag ntawm lub cev thiab lub cev sib tw yog {{ 0}} / 10000 ntawm txoj kab uas hla ntawm lub cev dov.Rau ib qho kev sib dhos angular hu rau cov kabmob, cov radial rated load yog cov radial tivthaiv ntawm cov load uas ua rau cov kabmob sib dhos rau txhua lwm tus txheeb ze rau cov ntshiab radial tawm.
11. Radial (lossis axial) sib npaug zoo li qub load
Cov hluav taws xob radial zoo li qub (lossis central axial zoo li qub thauj khoom) yuav ua rau tag nrho kev hloov kho tas mus li ntawm kev sib cuag ntawm lub cev dov thiab kev sib tw nyob rau hauv qhov kev ntxhov siab tshaj plaws zoo ib yam li tag nrho cov kev ua haujlwm tas mus li nyob rau hauv qhov tseeb kev mob.
