    Kauv Hluav Taws Xob Resistor Nicr Alloy 1 - 5 Mohm Rau Cov Cuab Yeej Cuab Yeej Cuab Yeej

     

    1.Material General Description

    Constantanyog tooj liab-nickel alloy tseem hu uaEureka,Ua ntej, thiabFerry.Nws feem ntau muaj 55% tooj liab thiab 45% npib tsib xee.Nws lub ntsiab feature yog nws resistivity, uas yog tas li nyob rau hauv ib tug ntau yam ntawm kub.Lwm cov alloys uas zoo sib xws tsis tshua muaj kub coefficients paub, xws li manganin (Cu86Mn12Ni2).

     

    Rau kev ntsuas ntawm cov kab mob loj heev, 5% (50 000 microstrian) lossis siab dua, annealed constantan (P alloy) yog cov khoom siv kab sib chaws feem ntau xaiv.Constantan nyob rau hauv daim ntawv no yog heevductile;thiab, hauv qhov ntsuas qhov ntev ntawm 0.125 ntiv tes (3.2 hli) thiab ntev dua, tuaj yeem raug strained rau> 20%.Nws yuav tsum tau borne nyob rau hauv lub siab, txawm li cas los xij, nyob rau hauv siab cyclic hom P alloy yuav nthuav tawm qee qhov kev hloov pauv mus tas li nrog txhua lub voj voog, thiab ua rau muaj qhov sib xws.xoomhloov nyob rau hauv lub strain gauge.Vim hais tias ntawm tus yam ntxwv no, thiab lub siab nyiam ua ntej daim phiaj tsis ua hauj lwm nrog rov straining, P alloy tsis nquag pom zoo rau kev siv cyclic strain.P alloy muaj nyob nrog STC tus lej ntawm 08 thiab 40 rau siv rau cov hlau thiab yas, feem.

     

    2. Caij nplooj ntoos hlav Taw qhia thiab kev siv

     

    Ib tug kauv torsion caij nplooj ntoos hlav, los yog hairspring, nyob rau hauv lub tswb moos.

    Ib lub caij nplooj ntoos hlav.Nyob rau hauv compression lub coils swb dua ib leeg, yog li them taus mus ntev dua.

    Vertical volute springs ntawm Stuart tank

    Nruas springs nyob rau hauv ib tug folded kab reverberation ntaus ntawv.

    Ib tug torsion bar twisted nyob rau hauv load

    Nplooj caij nplooj ntoos hlav ntawm lub tsheb
    Springs tuaj yeem raug cais nyob ntawm seb lub zog thauj khoom siv li cas rau lawv:

    Tension / ncua caij nplooj ntoos hlav - lub caij nplooj ntoos hlav yog tsim los khiav lag luam nrog ib tug nro load, yog li lub caij nplooj ntoos hlav stretches raws li lub load yog siv rau nws.
    Compression caij nplooj ntoos hlav - yog tsim los ua hauj lwm nrog ib tug compression load, yog li ntawd lub caij nplooj ntoos hlav tau luv luv raws li lub load yog siv rau nws.
    Torsion caij nplooj ntoos hlav - tsis zoo li cov saum toj no hom nyob rau hauv uas lub load yog ib tug axial quab yuam, lub load rau lub torsion caij nplooj ntoos hlav yog ib tug torque los yog twisting quab yuam, thiab qhov kawg ntawm lub caij nplooj ntoos hlav tig los ntawm lub kaum sab xis raws li lub load yog thov.
    Lub caij nplooj ntoos hlav tas li - kev txhawb nqa load tseem zoo ib yam thoob plaws lub voj voog deflection.
    Lub caij nplooj ntoos hlav sib txawv - qhov ua haujlwm ntawm lub kauj kom thauj khoom sib txawv thaum lub sijhawm compression.
    Lub caij nplooj ntoo hlav tsis sib haum xeeb - kev ua haujlwm ntawm lub kauj rau kev thauj khoom tuaj yeem hloov pauv hloov pauv piv txwv los ntawm kev tswj hwm, qee yam ntawm cov springs no kuj txawv lawv qhov ntev yog li muab kev muaj peev xwm ua tau zoo ib yam.
    Lawv tuaj yeem raug cais raws li lawv cov duab:

    Lub caij nplooj ntoos hlav tiaj tus - hom no yog ua los ntawm lub caij nplooj ntoos hlav ca.
    Machined caij nplooj ntoos hlav - hom caij nplooj ntoos hlav no yog tsim los ntawm machining bar Tshuag nrog lub tshuab dhos thiab / lossis milling ua haujlwm ntau dua li kev ua haujlwm coiling.Txij li thaum nws yog machined, lub caij nplooj ntoos hlav tuaj yeem sib txuas cov yam ntxwv ntxiv rau cov khoom elastic.Machined springs tuaj yeem ua rau hauv cov xwm txheej hnyav ntawm compression / extension, torsion, thiab lwm yam.
    Serpentine caij nplooj ntoos hlav - zig-zag ntawm tuab hlau - feem ntau siv nyob rau hauv niaj hnub upholstery / rooj tog.
