Qhov seem uas ob lub rollers txuas nrog lub phaj saw yog ib seem.
Lub phaj txuas sab hauv thiab lub tes tsho, lub phaj txuas sab nraud thiab tus pin txuas nrog kev cuam tshuam sib xws, uas hu ua txuas sab hauv thiab sab nraud. Qhov seem txuas ob lub rollers thiab lub phaj saw yog ib ntu, thiab qhov deb ntawm qhov chaw nruab nrab ntawm ob lub rollers hu ua lub suab.
Qhov ntev ntawm cov saw hlau yog sawv cev los ntawm tus lej ntawm cov saw hlau txuas Lp. Tus lej ntawm cov saw hlau txuas yog tus lej txawm, yog li cov phaj saw hlau sab hauv thiab sab nraud tuaj yeem txuas thaum cov saw hlau sib koom ua ke. Cov koob txuas lossis cov xauv caij nplooj ntoos hlav tuaj yeem siv ntawm cov pob qij txha. Yog tias tus lej ntawm cov saw hlau txuas yog khib, cov saw hlau hloov pauv yuav tsum tau siv ntawm qhov sib koom ua ke. Thaum cov saw hlau raug thauj khoom, cov saw hlau hloov pauv tsis yog tsuas yog dais lub zog tensile xwb, tab sis kuj dais ntxiv qhov hnyav khoov, uas yuav tsum tau zam ntau li ntau tau.
Kev Taw Qhia Txog Cov Saw Kis
Raws li cov qauv, cov saw hlau kis tau muab faib ua cov saw hlau dov, cov saw hlau hniav thiab lwm yam, ntawm cov saw hlau dov yog qhov siv dav tshaj plaws. Cov qauv ntawm cov saw hlau dov tau qhia hauv daim duab, uas muaj cov phaj saw hlau sab hauv 1, phaj saw hlau sab nraud 2, tus ncej pin 3, lub tes tsho 4 thiab lub log 5.
Ntawm lawv, lub phaj saw sab hauv thiab lub tes tsho, lub phaj saw sab nraud thiab lub ncej pin tau txuas ruaj khov los ntawm kev sib txuas, uas hu ua kev sib txuas saw sab hauv thiab sab nraud; cov menyuam thiab lub tes tsho, thiab lub tes tsho thiab lub ncej pin yog qhov sib txawv.
Thaum cov phaj sab hauv thiab sab nraud ntawm cov saw hlau raug tig mus rau sab nraud, lub tes tsho tuaj yeem tig tau yooj yim ncig lub qhov pin. Lub roller raug khi rau ntawm lub tes tsho, thiab thaum ua haujlwm, lub roller dov raws li cov hniav ntawm lub sprocket. Txo cov hniav iav hnav. Qhov hnav tseem ceeb ntawm cov saw hlau tshwm sim ntawm qhov sib txuas ntawm lub pin thiab lub bushing.
Yog li ntawd, yuav tsum muaj qhov sib txawv me me ntawm cov phaj sab hauv thiab sab nraud kom cov roj nplua nyeem tuaj yeem nkag mus rau hauv qhov sib txhuam. Feem ntau, cov phaj saw hlau ua rau hauv daim duab "8", yog li txhua qhov ntawm nws cov ntu hla muaj lub zog tensile ze li ntawm sib npaug, thiab tseem txo qhov hnyav ntawm cov saw hlau thiab lub zog inertial thaum lub sijhawm txav mus los.
