Hauv kev ua haujlwm, peb feem ntau siv tus qauv taw qhia thiab coj bushing sib koom tes nrog lwm tus. Thaum lub rooj sib txoos, koj yuav tsum ua tib zoo saib kom pom tseeb ntawm cov kab kev taw qhia thiab qhia txog kev txhuam. Yog hais tias qhov kev tshem tawm tsis tsim nyog, ces nws yuav yog qhov tsis zoo. Piv txwv li, yog hais tias qhov kev tshem ntawm cov qauv taw qhia thiab kev qhia bushing loj heev, ces nws yuav tsis ua tiav qhov kev xav tau. On qhov tsis tooj, nws yuav tsum ntom, thiab yooj yim rau hnav.
Nyob rau hauv lwm yam lus, kev koom tes ntawm cov qauv taw qhia thiab cov kev taw qhia txog kev sib tw yog zoo txog kev sib haum xeeb ntawm lawv. Qhov kev nyuab siab xav tau yog ua tiav yog tias qhov kev sib haum xeeb ntawm lawv yog tswj ntawm qhov tsim nyog. Li ntawd, ntau npaum li cas clearance yog tsim nyog?
Hauv kev pom ntawm qhov teeb meem no, ua ntej txhua yam, peb yuav tsum xub txiav txim seb qhov teeb tsa ntawm tus qauv coj. Feem ntau, nws qhov teeb tsa tsuas yog nyob ntawm cov duab ntawm workpiece, txoj kev blowdown thiab qhov teeb meem ntawm cov xovxwm. Tom qab ntawd, raws li qhov sib txawv ntawm cov lus pom ntawm lub qhov ncauj, qhov ua siab ntev ntawm txhua feem yuav tsum muaj qhov tsim nyog. Feem ntau, kev lag luam siab kam rau nruab nrab ntawm kev sib xyaw thiab concave koos yog nruab nrab ntawm ib nrab thiab ib feem peb ntawm cov tsis paub ntau ntxiv.
Nyob rau hauv ib txwm muaj kev mob, txoj hlua deflection variation ntau ntawm tus qauv qhia ntawv yog 0.2 mus rau 0.25, thiab tus clearance ntawm ib sab thiab phau ntawv qhia bushing yog 0.3 mus 0.5 rau qhov kev hloov ntawm kev dawb huv clearance. Tom qab ntawd peb tuaj yeem ua ke no los txiav txim nws qhov loj. Tom qab ntawd, qhov kev hloov ntawm daim ntawv dawb paug thiab daim ntawv npaj ua ke tau txiav txim siab kom pom tseeb tshaj plaws ntawm lawv. Nyob rau hauv no, qhov tsawg kawg nkaus clearance nruab nrab ntawm lawv yog txiav txim siab raws li daim ntawv kam rau ua ke ntawm phau ntawv qhia bushing.
Nco ntsoov tias yuav kom paub siv cov kev qhia ntawm tus qauv qhia ntawv, raws li tus neeg siv, peb yuav tsum tau ua lubrication zoo zoo. Nyob rau hauv qhov tseeb, rau tus qauv qhia, nws txoj kev los tiv thaiv corrosive nyob ntawm lub solubility thiab cov viscosity ntawm cov roj lubricating. Yog li ntawd, nco ntsoov xaiv cov roj ntim uas tsis tsim nyog.
