Qhov cuam tshuam ntawm kev vuam deformation ntawm lub peev xwm ntawm cov saw hlau: kev tshuaj xyuas tob thiab kev daws teeb meem
Hauv kev sib kis tshuab, cov saw hlau uas yog cov khoom siv tseem ceeb rau kev sib kis, yog siv dav hauv ntau yam lag luam xws li kev tsim khoom lag luam thiab kev thauj mus los. Nws lub luag haujlwm tseem ceeb yog xa lub zog thiab kev txav mus los, thiab lub peev xwm dais yog qhov qhia tseem ceeb los ntsuas qhov ua tau zoo ntawm cov saw hlau uas yog cov hlau, uas muaj feem cuam tshuam ncaj qha rau kev ua haujlwm zoo, kev ntseeg siab thiab lub neej ua haujlwm ntawm lub kaw lus kis. Raws li qhov teeb meem feem ntau hauv cov txheej txheem tsim khoom ntawm cov saw hlau uas yog cov hlau, kev vuam deformation muaj kev cuam tshuam tseem ceeb rau lub peev xwm dais ntawm cov saw hlau uas yog cov hlau. Tsab xov xwm no yuav tshawb nrhiav tob txog cov txheej txheem cuam tshuam, cov yam ntxwv cuam tshuam thiab cov kev daws teeb meem ntawm kev vuam deformation rau lub peev xwm dais ntawm cov saw hlau uas yog cov hlau.

1. Kev piav qhia txog cov qauv thiab lub peev xwm ntawm cov saw hlau
Cov saw hlau feem ntau yog ua los ntawm cov khoom yooj yim xws li cov phaj sab hauv, cov phaj sab nraud, cov koob, cov tes tsho thiab cov menyuam. Cov khoom no koom tes ua ke kom cov saw hlau dov thiab xa mus tau zoo ntawm lub sprocket. Lub peev xwm ntawm cov saw hlau feem ntau nyob ntawm lub zog thiab qhov sib phim ntawm nws cov khoom. Hauv qab kev ua haujlwm ib txwm muaj, cov saw hlau yuav tsum tiv taus ntau yam kev thauj khoom nyuaj xws li kev nruj, kev nyuaj siab, kev ntxhov siab khoov, thiab lwm yam.
Feem ntau hais lus, lub peev xwm thauj khoom ntawm cov saw hlau yog cuam tshuam los ntawm ntau yam, suav nrog cov khoom siv ntawm cov saw hlau, qhov loj me, cov txheej txheem tsim khoom, cov xwm txheej lubrication, thiab qhov chaw ua haujlwm. Cov ntaub ntawv zoo thiab cov txheej txheem tsim khoom tsim nyog tuaj yeem txhim kho lub zog thiab kev tiv thaiv kev hnav ntawm cov saw hlau, yog li ua rau lawv lub peev xwm thauj khoom zoo dua. Cov xwm txheej lubrication zoo tuaj yeem txo qhov kev sib txhuam thiab kev hnav, ntev lub neej kev pabcuam ntawm cov saw hlau, thiab txhim kho lawv lub peev xwm thauj khoom tsis ncaj qha.

2. Lub tswv yim thiab ua rau muaj kev hloov pauv ntawm vuam
Kev vuam deformation yog hais txog qhov tsis sib npaug ntawm qhov ntim thiab kev sib cog lus ntawm cov khoom ua haujlwm tag nrho lossis hauv zos vim yog qhov cua sov thiab txias hauv zos thaum lub sijhawm vuam, uas ua rau muaj kev hloov pauv ntawm cov duab thiab qhov loj me. Hauv kev tsim cov saw hlau, cov txheej txheem vuam feem ntau siv los txuas ntau yam khoom, xws li vuam lub qhov txuas rau lub phaj saw sab nraud, lossis vuam lub tes tsho rau lub phaj saw sab hauv.
Kev vuam deformation feem ntau yog tshwm sim los ntawm cov laj thawj hauv qab no:
Kev kub tsis sib xws: Thaum lub sijhawm vuam, thaj chaw vuam raug cua sov ntawm qhov kub siab, thaum cov khoom siv nyob ib puag ncig kub qis dua. Qhov kev kub tsis sib xws no ua rau cov khoom siv nthuav dav tsis sib xws, nrog rau thaj chaw vuam nthuav dav ntau dua thiab thaj chaw ib puag ncig nthuav dav tsawg dua, ua rau muaj kev ntxhov siab thiab kev hloov pauv vuam.
Kev Hloov Pauv Cov Qauv Hlau: Cov khoom siv hlau hauv thaj chaw uas raug cua sov ntawm kev vuam yuav raug hloov pauv cov qauv hauv qab qhov kub siab, xws li los ntawm austenite mus rau martensite. Qhov kev hloov pauv qauv no nrog rau kev hloov pauv ntawm qhov ntim, uas yuav ua rau shrinkage lossis nthuav dav ntawm thaj chaw, thiab tom qab ntawd ua rau kev vuam deformation.
Kev vuam tsis tsim nyog: Yog tias qhov kev vuam tsis tau teeb tsa kom zoo, qhov kev txwv ntawm cov khoom ua haujlwm thaum lub sijhawm vuam yuav tsis sib npaug, yog li qhov kev ntxhov siab vuam hauv qee qhov chaw tsis tuaj yeem tso tawm tau zoo, yog li ua rau qhov kev hloov pauv vuam hnyav dua.

3. Lub tshuab ntawm kev cuam tshuam ntawm kev vuam deformation ntawm lub peev xwm ntawm cov menyuam saw hlau
Kev vuam deformation yuav cuam tshuam rau lub peev xwm ntawm cov saw hlau los ntawm ntau yam, feem ntau yog hauv cov hauv qab no:
Cuam tshuam rau cov duab geometric thiab qhov tseeb ntawm cov khoom: Kev hloov pauv ntawm kev vuam yuav ua rau muaj kev cuam tshuam, khoov lossis qhov sib txawv ntawm ntau yam khoom ntawm cov saw hlau. Piv txwv li, lub phaj saw hlau sab nraud lossis lub phaj saw hlau sab hauv yuav wavy lossis tsis sib xws hauv zos tom qab vuam, uas yuav rhuav tshem cov duab tsim qub thiab qhov tseeb ntawm lub phaj saw hlau. Hauv cov txheej txheem kis ntawm cov saw hlau, lub phaj saw hlau yuav tsum tau sib phim ze nrog cov hniav ntawm lub sprocket kom ntseeg tau tias muaj kev xa hluav taws xob raug. Yog tias cov duab thiab qhov loj ntawm lub phaj saw hlau hloov pauv, nws yuav ua rau muaj kev sib txuas tsis zoo ntawm lub phaj saw hlau thiab lub sprocket, ua rau muaj kev cuam tshuam thiab kev co ntawm cov saw hlau thaum lub sijhawm ua haujlwm, thiab yog li txo qhov muaj peev xwm thauj khoom ntawm cov saw hlau.
Txo qhov muaj zog thiab qhov tawv ntawm cov khoom: Qhov kev ntxhov siab ntawm kev vuam uas tsim thaum lub sijhawm vuam deformation yuav ua rau muaj qhov tsis zoo me me thiab kev hloov pauv ntawm cov qauv hauv cov khoom siv hlau ntawm cov saw hlau. Cov qhov tsis zoo thiab kev hloov pauv ntawm cov qauv no yuav txo qhov muaj zog thiab qhov tawv ntawm cov khoom, ua rau cov saw hlau yooj yim dua rau kev hloov pauv thiab kev puas tsuaj thaum nqa cov khoom hnyav. Piv txwv li, cov khoom siv hlau hauv thaj chaw cuam tshuam los ntawm cua sov ntawm kev vuam yuav ua rau nws cov noob coarsens vim qhov kub siab, ua rau cov khoom siv kho tshuab ntawm cov khoom txo qis. Tsis tas li ntawd, qhov kev hloov pauv ntawm kev vuam kuj tseem yuav ua rau muaj kev ntxhov siab hauv zos hauv thaj chaw vuam, ua rau lub zog thiab lub peev xwm thauj khoom ntawm qhov vuam qaug zog ntxiv.
Ua kom puas qhov tseeb ntawm kev sib phim ntawm cov khoom sib txawv: Muaj kev sib raug zoo ntawm ntau yam khoom ntawm cov saw hlau, xws li tus pin thiab lub tes tsho, lub phaj saw hlau thiab tus pin, thiab lwm yam. Kev hloov pauv ntawm kev vuam yuav ua rau qhov sib phim ntawm cov khoom no nce lossis qhov sib phim nruj dhau. Thaum qhov sib phim loj dhau, cov saw hlau yuav ua rau muaj kev co thiab cuam tshuam ntau dua thaum lub sijhawm ua haujlwm, ua kom cov khoom hnav sai dua, thiab txo qhov muaj peev xwm thauj khoom. Yog tias qhov haum nruj dhau, cov saw hlau yuav nyuaj rau tig thiab txav mus los, ua rau muaj kev tiv thaiv khiav ntau dua, thiab tseem cuam tshuam rau nws qhov muaj peev xwm thauj khoom.

4. Cov kev qhia tshwj xeeb ntawm qhov cuam tshuam ntawm kev vuam deformation ntawm lub peev xwm thauj khoom ntawm cov saw hlau
Txo qhov muaj peev xwm thauj khoom zoo li qub: Nyob rau hauv qhov thauj khoom zoo li qub, qhov siab tshaj plaws ntawm qhov nro uas cov saw hlau tuaj yeem tiv taus tom qab vuam deformation yuav raug txo qis vim yog qhov txo qis ntawm lub zog thiab kev nruj ntawm cov khoom thiab kev puas tsuaj ntawm qhov haum. Qhov no txhais tau tias nyob rau hauv tib qhov thauj khoom zoo li qub, cov saw hlau nrog kev vuam deformation hnyav yuav ua tsis tiav vim yog cov yas deformation lossis tawg.
Txo qhov muaj peev xwm thauj khoom qaug zog: Cov saw hlau feem ntau raug rau cov khoom thauj rov ua dua thaum lub sijhawm ua haujlwm tiag tiag, thiab qhov muaj peev xwm thauj khoom qaug zog yog ib qho ntawm nws cov cim qhia kev ua tau zoo tseem ceeb. Cov yam xws li kev hloov pauv ntawm cov qauv khoom siv los ntawm kev vuam deformation, kev ntxhov siab vuam, thiab kev sib haum xeeb tsis zoo ntawm cov khoom yuav ua rau nws yooj yim dua rau cov kab nrib pleb qaug zog hauv cov saw hlau kom pib thiab nthuav dav hauv qab cov khoom thauj cyclic, yog li txo lawv lub neej qaug zog thiab lub peev xwm thauj khoom qaug zog.
Lub peev xwm thauj khoom tsis muaj zog: Nyob rau hauv cov xwm txheej ua haujlwm dynamic, cov saw hlau yuav tsum tau tiv taus cov khoom hnyav xws li kev cuam tshuam thiab kev co. Qhov kev hloov pauv geometric thiab cov teeb meem sib phim ntawm cov khoom ua los ntawm kev vuam deformation yuav ua rau lub nra hnyav ntawm cov saw hlau thaum ua haujlwm dynamic, ua rau kev txav mus los tsis ruaj khov, thiab yog li txo nws lub peev xwm dynamic bearing.

5. Cov yam ntxwv uas cuam tshuam rau kev vuam deformation thiab kev tswj hwm
Yuav kom txo tau cov teebmeem tsis zoo ntawm kev vuam deformation ntawm lub peev xwm ntawm cov saw hlau, nws yog ib qho tsim nyog kom nkag siab tob txog cov yam ntxwv uas cuam tshuam rau kev vuam deformation thiab ua cov kev ntsuas tswj hwm.
