Kodi malamba ogwiritsira ntchito nthawi ndi chiyani?

Malamba ogwiritsira ntchito nthawi ndi mipiringidzo yokhuthala yopangidwa ndi rabara yomwe ili ndi mano olimba ndi mipiringidzo mkati mwake zomwe zimawathandiza kulumikiza mawilo a ma crankshaft ndi ma camshaft. Amagwiritsidwa ntchito kupatsa mphamvu ndikuthandizira ntchito m'mapampu amadzi, mapampu amafuta, ndi mapampu obayira, monga momwe kapangidwe ka injini kamafunira. Amagwiritsidwa ntchito kwambiri m'mainjini oyaka mkati kuti ma valve a injini atsegulidwe ndi kutsekedwa mozungulira nthawi.

 

Kodi ntchito za malamba ogwiritsira ntchito nthawi ndi ziti?

Ma lamba ogwiritsira ntchito nthawi ogwira ntchito bwino kwambiri ali ndi ntchito zotsatirazi:

Imachita gawo lofunika kwambiri pakuyendetsa bwino ntchito yoyaka moto mwa kuwongolera bwino pisitoni ndi ma valve.

Imalamulira ntchito ya valavu polumikiza crankshaft ndi camshaft pamodzi.

Imasamalira kutsegula ndi kutseka ma valve a injini pamodzi.

Zimachotsa kufunikira kwa mphamvu zakunja kuti zigwire ntchito potsegula ndi kutseka ma valve pogwiritsa ntchito mphamvu yamakina ya injini yoyaka.

Chimodzi mwa ntchito zofunika kwambiri komanso kugwiritsa ntchito malamba ogwiritsira ntchito nthawi ndikuti chimalepheretsa pisitoni kugunda kwambiri ma valve.

Ngakhale kuti ndi lamba kapena chipangizo chimodzi, zimathandiza kwambiri pakugwira ntchito kwa zinthu zingapo monga upper balance shaft sprocket, lower balance shaft sprocket, camshaft lamba drive gear, balance lamba drive gear, balance lamba tensioner roller, ndi timing lamba tensioner roller.

 

Kodi njira yogwirira ntchito ya malamba ogwiritsira ntchito nthawi ndi yotani?

Malamba ogwiritsira ntchito nthawi amagwirizanitsa ntchito yotseka ndi kutsegula ndi nthawi ya crankshaft, camshaft, ndi valavu yotulutsa mpweya. Zimathandiza kuti mafuta ndi mpweya zilowe mu injini yoyaka, komanso kulamulira valavu yotulutsa mpweya kuti utsi kapena utsi utuluke. Lamba limasunga injini mogwirizana ndipo limasunga mphamvu zake komanso kugwira ntchito bwino.

 

Kodi ndi liti pamene muyenera kusintha lamba wa nthawi?

Kuwoneka kwa zizindikirozi kumasonyeza kufunika kosintha lamba wakale komanso wokalamba ndikuyika lamba watsopano wa nthawi:

Mphamvu ya injini yotsika

Kutentha kwambiri kwa injini

Kugwedezeka kapena kugwedezeka mu injini

Kuvuta kuyambitsa makina kapena galimoto

Phokoso lokweza kapena kufuula lochokera m'lamba

Phokoso lomveka bwino likumveka kuchokera mu injini

Mafuta akutuluka mu injini

Kusagwira bwino ntchito kwa nyali ya injini
