Kev hloov kho iav tuaj yeem txhim kho qhov tseeb ntawm kev sib kis thiab ua rau lub zog ntawm iav muaj zog dua. Kev hloov kho iav yog hais txog kev ntsuas thev naus laus zis los txiav cov hniav ntawm lub iav me me kom nws tsis sib xws nrog cov hniav uas tau xav tseg. Muaj ntau yamhom iavkev hloov kho hauv kev nkag siab dav, raws li qhov sib txawv ntawm kev hloov kho, kev hloov kho hniav iav tuaj yeem muab faib ua kev hloov kho hniav thiab kev hloov kho kev taw qhia hniav.

Kev hloov kho cov qauv hniav

Cov hniav profile raug txiav me ntsis kom nws tsis zoo li cov hniav profile theoretical. Kev hloov kho cov hniav profile suav nrog kev txiav, kev txiav hauv paus thiab kev khawb hauv paus. Kev txiav ntug yog kev hloov kho cov hniav profile ze ntawm cov hniav crest. Los ntawm kev txiav cov hniav, kev co thiab suab nrov ntawm cov hniav iav tuaj yeem txo qis, lub nra hnyav dynamic tuaj yeem txo qis, lub xeev lubrication ntawm qhov chaw hniav tuaj yeem txhim kho, thiab kev puas tsuaj ntawm cov kua nplaum tuaj yeem qeeb lossis tiv thaiv. Rooting yog kev hloov kho cov hniav profile ze ntawm cov hauv paus hniav. Cov nyhuv ntawm kev txiav hauv paus yog qhov zoo ib yam li kev txiav ntug, tab sis kev txiav hauv paus ua rau lub zog khoov ntawm cov hauv paus hniav tsis muaj zog. Thaum siv cov txheej txheem sib tsoo los hloov kho cov duab, txhawm rau txhim kho kev ua haujlwm zoo, cov iav me me qee zaum siv hloov cov iav loj sib phim uas yuav tsum tau txiav. Rooting yog kev hloov kho ntawm qhov chaw hloov pauv hauv paus ntawm cov hniav iav. Cov iav tawv thiab carburized yuav tsum tau sib tsoo tom qab kev kho cua sov. Txhawm rau kom tsis txhob muaj kev sib tsoo kub hnyiab ntawm cov hauv paus hniav thiab tswj cov txiaj ntsig zoo ntawm kev ntxhov siab seem, cov hauv paus hniav yuav tsum tsis txhob sib tsoo. hauv paus. Tsis tas li ntawd xwb, qhov radius ntawm curvature ntawm cov cag hloov pauv tuaj yeem nce ntxiv los ntawm kev khawb kom txo qhov kev ntxhov siab ntawm cov cag fillet.

Kev hloov kho cov hlau txhuas hniav

Cov hniav nto raug txiav me ntsis raws li txoj kab hniav kom nws tsis sib haum nrog cov hniav theoretical. Los ntawm kev hloov kho qhov kev taw qhia ntawm cov hniav, qhov kev faib khoom tsis sib xws ntawm cov kab sib cuag ntawm cov hniav iav tuaj yeem txhim kho, thiab lub peev xwm ntawm cov iav tuaj yeem txhim kho. Cov txheej txheem txiav hniav feem ntau suav nrog kev txiav hniav kawg, kev txiav lub kaum sab xis helix, kev txiav nruas thiab kev txiav qhov chaw. Kev txiav cov hniav kawg yog maj mam ua kom cov hniav tuab mus rau qhov kawg ntawm ib lossis ob qho kawg ntawm cov hniav iav ntawm ib ntu me me ntawm qhov dav ntawm cov hniav. Nws yog txoj kev hloov kho yooj yim tshaj plaws, tab sis qhov cuam tshuam txiav tsis zoo. Kev txiav lub kaum sab xis Helix yog hloov me ntsis qhov kev taw qhia ntawm cov hniav lossis lub kaum sab xis helix β, kom qhov chaw ntawm cov hniav tiag tiag tsis sib haum nrog qhov chaw ntawm cov hniav theoretical. Kev txiav lub kaum sab xis Helix zoo dua li kev txiav cov hniav kawg, tab sis vim tias lub kaum sab xis hloov me me, nws tsis tuaj yeem muaj qhov cuam tshuam loj rau txhua qhov chaw ntawm cov hniav. Kev txiav nruas yog siv kev txiav hniav kom cov hniav iav loj hlob hauv nruab nrab ntawm qhov dav ntawm cov hniav, feem ntau sib npaug ntawm ob sab. Txawm hais tias lub nruas trimming tuaj yeem txhim kho qhov kev faib khoom tsis sib xws ntawm cov kab sib cuag ntawm cov hniav iav, vim tias qhov kev faib khoom ntawm ob qho kawg ntawm cov hniav tsis zoo ib yam, thiab qhov yuam kev tsis tau faib tag nrho raws li lub nruas zoo li cas, qhov cuam tshuam trimming tsis zoo tagnrho. Kev hloov kho qhov chaw yog hloov kho qhov kev taw qhia ntawm cov hniav raws li qhov yuam kev thauj khoom eccentric tiag tiag. Xav txog qhov yuam kev thauj khoom eccentric tiag tiag, tshwj xeeb tshaj yog xav txog thermal deformation, qhov chaw hniav tom qab trimming tej zaum yuav tsis tas li bulged, tab sis feem ntau yog qhov chaw nkhaus txuas nrog concave thiab convex. Qhov cuam tshuam trimming ntawm qhov chaw zoo dua, thiab nws yog ib txoj kev txiav zoo tagnrho, tab sis kev suav yog qhov teeb meem ntau dua thiab cov txheej txheem nyuaj dua.
