NSK tau tsim lub zog txuag hluav taws xob
Thiaj li yuav tsum txhim kho cov kev lag luam tam sim no kom muaj zog, Seiko Co., Ltd. tau nyuam qhuav tsim kev poob qis rau cov tshuab txuag hluav taws xob. Cov khoom no tuaj yeem txo qhov kev sib txhuam poob hauv qhov kev coj mus rau ib nrab ntawm qhov tseemceeb, yog li ua tau lub zog txuag tau. NSK predicts tias kev muag khoom ntawm cov khoom no yuav nce 7 billion yen los ntawm 2016.
Kev loj hlob tom qab
Nyob rau hauv lub xyoo dhau los, thiaj li tiv thaiv ntiaj teb cua sov, lub teb chaws cog lus rau kev txuag hluav taws xob thiab txo cov emission. Tshwj xeeb tshaj yog, cov cav siv nyiaj rau 75% ntawm kev siv hluav taws xob hauv ntau yam xws li ntau lawm. Vim li no, lub teb chaws muaj siab nrhuav lawv lub zog ua haujlwm rau lub zog kom txo tau kev siv zog. Hauv xyoo 2008, lub International Electrotechnical Commission (ntxiv mus rau IEC) tau tsim thiab muab cov qauv kev siv hluav taws xob thoob ntiaj teb ua ke. Ntawm cov xwm txheej uas txiav txim siab lub zog ntawm lub cav, qhov poob ntawm lub cav tsis xws li hlau poob, tooj liab, kab poob, cua poob, thiab lwm yam. Accounts rau 90%, thiab poob ntawm cov kabmob nkaus xwb nyiaj rau 10% . Nrog rau kev sib tw ntawm cov motors rau cov qauv siv hluav taws xob zoo dua qub xws li * IE3 thiab IE4, qhov yuav tsum tau ua kom tsis muaj kev tiv thaiv tsis tau zoo dua.
IE3, IE4 qib: IEC tsim zog efficiency ntsuam xyuas, IE1 (txuj ci) IE2 (zog dua zog) IE3 (high energy efficiency) IE4 (ultra-siab zog efficiency)
Nta
Cov khoom siv no ua tau haujlwm ultra-high speed lub lag luam thiab durability los ntawm cov nta nram qab no.
◆ Piv nrog rau cov khoom qub, poob qis los ntawm ib nrab.
Qhov poob yog hla los ntawm qhov tsim qhov tsim ntawm kabmob.
Khoom ua tau zoo
1. Ua kom lub zog txuag hluav taws xob kom zoo dua qub
Nws tuaj yeem npaj cov khoom siv txuag hluav taws xob uas ua tau raws li cov qauv siv hluav taws xob ntawm JIS lossis IE3 thiab IE4, thiab txo lub zog ntawm lub cav.
2. Txhim kho kev ntseeg siab
Txhim kho qhov kev ntseeg ntawm lub cav thiab cov khoom siv los ntawm kev txo cov bearing losses thiab suppressing qhov kub ntawm cov kabmob.
