Ubomi bokuthwala

Ukubala Ubomi bokuthwala: Imithwalo kunye nesantya sokuthwala

Ubomi bokuthwala buhlala bulinganiswa kusetyenziswa ukubala kwe-L10 okanye i-L10h. Olu balo ngokusisiseko lutshintsho lwezibalo zobomi bokuthwala nganye nganye. Ubomi be-L10 bebheri njengoko buchazwe yimigangatho ye-ISO kunye ne-ABMA busekelwe kubomi obuya kufikelela okanye budlule kwi-90% yeqela elikhulu leebheri ezifanayo. Ngamafutshane, ubalo lokuba i-90% yeebheri iya kuhlala ixesha elingakanani kwisicelo esithile.

Ukuqonda Ubomi bokuthwala iiRoller ze-L10

L10h = Ubomi obusisiseko bovavanyo kwiiyure

P = Umthwalo olinganayo onamandla

C = Uvavanyo olusisiseko lomthwalo oguqukayo

n = Isantya sokujikeleza

p = 3 kwiibheringi zebhola okanye 10/3 kwiibheringi zerola

I-L10 – uhlengahlengiso olusisiseko lomthwalo

Ii-L10 – umlinganiselo womthwalo osisiseko kumgama (KM)

 

Njengoko unokubona kwi-equation engasentla, ukuze kuchongwe ubomi be-L10 bebheriya ethile, kufuneka imithwalo ye-radial kunye ne-axial kunye nesantya sokujikeleziswa kwesicelo (ii-RPM). Ulwazi lokwenyani lokulayisha kwesicelo ludityaniswe nokulinganiswa komthwalo webheriya ukuze kuchongwe umthwalo odibeneyo okanye umthwalo olinganayo weDynamic ofunekayo ukuze kugqitywe ukubalwa kobomi.

Ukubala nokuqonda ukuthwala ubomi

P = Umthwalo oDibeneyo (Umthwalo oLinganayo oDynamic)

X = Isici somthwalo we-radial

Y = Into yomthwalo we-Axial

Fr = Umthwalo we-radial

I-Fa = Umthwalo we-Axial

Qaphela ukuba i-L10 Life Calculation ayicingi ngobushushu, ukuthambisa kunye nezinye izinto ezibalulekileyo ezibalulekileyo ekufezekiseni ubomi bokufaka iibheringi obuyilelweyo. Unyango olufanelekileyo, ukuphathwa, ukugcinwa kunye nokufakelwa konke kucingelwa nje. Yingakho kunzima kakhulu ukuqikelela ukudinwa kweebheringi kunye nesizathu sokuba ngaphantsi kwe-10% yeebheringi zihlangabezana okanye zidlule ubomi bazo bokudinwa obubaliweyo.

Yintoni Emisela Ubomi Benkonzo Yomntu Osebenza Naye?

Ngoku ekubeni uyiqonda kakuhle indlela yokubala ubomi obuqhelekileyo bokudinwa kunye nolindelo lwee-rolling bearings, makhe sigxile kwezinye izinto ezimisela ixesha lokuphila. Ukuguguleka kwendalo yeyona nto ixhaphakileyo yokuqhekeka kwee-bearings, kodwa ii-bearings nazo zinokungaphumeleli ngaphambi kwexesha ngenxa yobushushu obugqithisileyo, ukuqhekeka, ukungabikho kokuthambisa okanye umonakalo kwiiseal okanye kwiikheyiji. Olu hlobo lomonakalo wee-bearings ludla ngokuba sisiphumo sokukhetha ii-bearings ezingalunganga, ukungachaneki kuyilo lwezinto ezijikelezileyo, ukufakwa okungalunganga okanye ukungabikho kolondolozo kunye nokuthambisa ngokufanelekileyo.
