NTN Corporation (tom qab no hu ua NTN) tau tsim "txhim kho cov cim sib sib zog nqus groove pob bearings" nrog lub zog zoo li qub ntawm cov kabmob sib tw, uas tuaj yeem siv rau hauv cov tsheb sib txawv (kev sib kis kab ke siv hauv tsheb nrog lub log xws li tsheb sib txawv them rau qhov sib txawv ntawm lub log ceev (qhov sib txawv ntawm qhov sib txawv ntawm lub log sab hauv thiab sab nraud) thaum lub tsheb tig thiab xyuas kom meej tias lub log tsheb. torque yog sib npaug sib npaug ntawm chav tsev fais fab) (tom qab no hu ua qhov sib txawv) thiab kev sib kis.
Vim tias qhov yuav tsum tau ua ntawm cov tsheb loj zuj zus ntxiv rau kev txhim kho roj efficiency thiab txo cov pa roj carbon dioxide emissions, bearings yuav tsum tau qis torque thiab ntau dua efficiency. Bearings siv nyob rau hauv kis kab mob Cheebtsam xws li txawv thiab kis tau tus mob yog raug rau loj thrust loads. Yog li ntawd, tapered roller bearings tau dav siv hauv cov ntawv thov no. Txawm li cas los xij, tapered roller bearings muaj qee qhov teeb meem, xws li kev sib hloov torque siab thiab yuav tsum tau kho cov khoom ua ntej thaum sib dhos. Hauv qhov sib piv, cov pob bearings muaj lub zog qis dua thiab tuaj yeem txhawb nqa lub zog, tab sis lawv lub zog thrust load tsawg thiab tsis tuaj yeem ua tau raws li daim ntawv thov.
NTN's tshiab tsim "txhim kho qhov ntsuas qhov sib sib zog nqus groove pob bearing" muaj qhov tshwj xeeb ntawm qhov chaw hloov kho thaum lub sij hawm kho cua sov, thiab nws cov brinelling (yas deformation indentation sab laug ntawm ib yam khoom tom qab lub zog tshaj cov yas txwv ntawm cov khoom raug tshem tawm thaum ob yam khoom. yog nyob rau hauv Hertzian kev sib cuag) qhov tob (qhov taw qhia qhov muaj peev xwm zoo li qub) txo mus rau 1/2 piv rau cov txheej txheem kev kho cua sov, tso cai rau cov menyuam bearings siv hauv qhov sib txawv thiab lwm yam kev siv los ua. hloov nrog pob bearings, thiab lub torque ntawm qhov sib txawv sab bearings yuav tsum tau txo los ntawm 60% (piv rau cov tapered roller bearings siv nyob rau hauv qhov sib txawv ntawm 2- litre qauv, lub cav torque load yog 70% thiab kev tsav tsheb ceev yog 100 km / h).
Ntxiv rau qhov zoo li saum toj no, kev siv kev txhim kho los tiv thaiv kev sib sib zog nqus groove pob bearings kuj tuaj yeem txo cov neeg-teev cov sijhawm xav tau rau kev sib dhos thiab kev tswj xyuas ua ntej, pab txhim kho kev tsim khoom ntawm cov tuam txhab tsheb.
