Chain length precision yuav tsum tau ntsuas raws li cov hauv qab no
A. Cov saw hlau raug ntxuav ua ntej ntsuas
B. Qhwv cov saw nyob rau hauv kev sim nyob ib ncig ntawm ob lub sprockets.Lub sab sauv thiab sab qis ntawm cov saw hauv kev sim yuav tsum tau txais kev txhawb nqa.
C. Cov saw hlau ua ntej ntsuas yuav tsum nyob rau 1 feeb nyob rau hauv cov xwm txheej ntawm kev thov ib feem peb ntawm qhov tsawg kawg nkaus tensile load.
D. Thaum ntsuas, siv qhov ntsuas qhov ntsuas ntawm cov saw hlau kom nruj rau cov saw hlau sab saud thiab qis.Cov saw thiab sprocket yuav tsum xyuas kom meej meshing.
E. Ntsuas qhov nruab nrab ntawm qhov nruab nrab ntawm ob lub sprockets
Ntsuas chain elongation
1. Yuav kom tshem tawm cov kev ua si ntawm tag nrho cov saw, nws yog ib qho tsim nyog los ntsuas nrog ib qho kev sib tw ntawm kev rub nro ntawm cov saw hlau.
2. Thaum ntsuas, txhawm rau txo qhov yuam kev, ntsuas ntawm ntu 6-10 (txuas ntxiv)
3. Ntsuas lub puab L1 thiab sab nraud L2 qhov ntev ntawm cov chais ntawm tus naj npawb ntawm ntu kom pom qhov kev txiav txim loj L = (L1 + L2) / 2
4. Nrhiav qhov elongation ntev ntawm cov saw hlau.Tus nqi no yog muab piv nrog rau kev siv txwv tus nqi ntawm cov saw elongation hauv kab lus dhau los.
Chain elongation = Kev txiav txim loj - siv ntev / siv ntev * 100%
Reference length = saw pitch * naj npawb ntawm qhov txuas
