①Thaum cov kabmob sab hauv txoj kab uas hla ntawm qhov kam rau ua rau thaj tsam thiab thaj tsam kam rau ua kom haum, txoj cai kam rau ua uas yog Ameslikas hloov pauv haum rau hauv lub hauv paus qhov system yuav dhau los ua kom haum, xws li k5, k6, m5, m6, n6 , thiab lwm yam, tab sis tus nqi dhau-yeej tsis yog Loj; Thaum lub sab hauv txoj kab uas hla ntawm lub bearings yog txuam nrog h5, h6, g5, g6, thiab lwm yam., nws tsis yog ib tug clearance tab sis ib tug dhau-yeej haum.

②Vim tias tus nqi kam rau ntawm cov kabmob sab nraud yog qhov sib txawv ntawm cov khoom siv dav dav, nws kuj yog ib cheeb tsam tshwj xeeb. Feem ntau, lub nplhaib sab nrauv yog tsau rau hauv lub qhov hauv tsev, thiab qee qhov kev coj tus kheej yuav tsum tau hloov kho raws li cov qauv tsim, thiab lawv cov kev sib koom ua ke tsis haum. nruj heev, feem ntau koom tes nrog H6, H7, J6, J7, Js6, Js7, thiab lwm yam.

Kev sib txuas: Raws li qhov xwm txheej ib txwm muaj, tus ncej feem ntau cim nrog 0 ~ + 0.005. Yog tias nws tsis feem ntau disassembled, nws yog +0.005 ~ + 0.01 cuam tshuam haum. Yog tias koj xav disassemble nquag, nws yog qhov kev hloov pauv haum. Peb kuj yuav tsum xav txog cov thermal expansion ntawm cov khoom ncej nws tus kheej thaum lub sij hawm kev sib hloov, yog li qhov loj ntawm cov kabmob yog, qhov zoo dua qhov clearance haum yog -0.005 ~ 0, thiab qhov siab tshaj plaws clearance haum yuav tsum tsis txhob ntau tshaj 0.01. Lwm qhov yog qhov cuam tshuam ntawm qhov txav ntawm lub kauj thiab tshem tawm ntawm lub nplhaib zoo li qub.

Bearing fits feem ntau hloov pauv haum, tab sis cuam tshuam haum yog xaiv tau hauv cov xwm txheej tshwj xeeb, tab sis tsis tshua muaj. Vim tias qhov sib tw ntawm cov kabmob thiab cov ncej yog qhov sib tw ntawm lub nplhaib puab ntawm cov kabmob thiab cov ncej, lub hauv paus qhov system yog siv. Keeb kwm, cov kabmob yuav tsum yog xoom. Thaum qhov tsawg kawg nkaus txwv qhov sib npaug, lub nplhaib puab yob thiab ua rau lub ntsej muag ntawm lub ntsej muag, yog li peb cov kabmob puab lub nplhaib muaj qhov sib txawv qis dua ntawm 0 mus rau ob peb μ kom ntseeg tau tias lub nplhaib puab tsis tig, yog li cov kabmob feem ntau xaiv. Kev hloov pauv haum, txawm tias txawm tias qhov kev hloov pauv haum raug xaiv, qhov cuam tshuam yuav tsum tsis pub tshaj 3 xov hlau.

Qhov sib piv qhov tseeb yog feem ntau xaiv ntawm qib 6. Qee zaum nws nyob ntawm cov khoom siv thiab kev siv tshuab. Hauv txoj kev xav, qib 7 yog qhov qis me ntsis, thiab yog tias nws sib haum nrog qib 5, kev sib tsoo yuav tsum tau ua.
