1. Galimoto ili ndi moto wothamanga kwambiri, koma nthawi yoyambira ndi yaitali, ndipo galimotoyo imatha kuthamanga;

2. Panthawi yoyambira, crankshaft idzasinthidwa, ndipo kuchuluka kwa kudya kudzabwezeredwa;

3. Kuthamanga kwa galimoto kumakhala kosasunthika ndipo kugwedezeka kumakhala koopsa, komwe kuli kofanana ndi kulephera kwa galimoto yopanda silinda;

4. Kuthamanga kwa galimoto sikukwanira, galimotoyo singathe kuthamanga, ndipo liwiro limaposa 2500 rpm;

5. Galimoto imakhala ndi mafuta ambiri, kutulutsa mpweya kumaposa muyezo, ndipo chitoliro chotulutsa mpweya chidzatulutsa utsi wakuda.

Kulephera kofala kwa ma camshaft kumaphatikizapo kuvala kwachilendo, phokoso lachilendo, ndi kusweka. Zizindikiro za kuvala kwachilendo ndi kung'ambika nthawi zambiri zimawonekera phokoso losadziwika bwino ndi kuthyoka kumachitika.

1. Camshaft ili pafupi kumapeto kwa makina opangira mafuta a injini, kotero kuti mafuta otsekemera alibe chiyembekezo. Ngati kukakamiza kwamafuta a pampu yamafuta sikukwanira chifukwa chogwiritsidwa ntchito kwanthawi yayitali, kapena njira yamafuta opaka mafuta yatsekedwa kuti mafuta opaka mafuta asafike pa camshaft, kapena ma torque omangitsa a ma bolts okhala ndi kapu ndi yayikulu kwambiri, mafuta opaka sangathe kulowa chilolezo cha camshaft, ndipo Zimayambitsa kuvala kwachilendo kwa camshaft.

2. Kuvala kwachilendo kwa camshaft kudzachititsa kuti kusiyana pakati pa camshaft ndi mpando wonyamulira kuchuluke, ndipo kusuntha kwa axial kudzachitika pamene camshaft imayenda, zomwe zimabweretsa phokoso losazolowereka. Kuvala kwachilendo kumapangitsanso kusiyana pakati pa makina oyendetsa galimoto ndi chonyamulira cha hydraulic kuti chiwonjezeke, ndipo kamerayo imagundana ndi chonyamulira cha hydraulic ikaphatikizidwa, zomwe zimapangitsa kuti pakhale phokoso lachilendo.

3. Zolephera zazikulu monga kusweka kwa camshaft nthawi zina zimachitika. Zomwe zimayambitsa nthawi zambiri ndi monga ma tapeti a hydraulic osweka kapena kuvala kwambiri, mafuta osakwanira bwino, camshaft yabwino, ndi zida zosweka za nthawi ya camshaft.

4. Nthawi zina, kulephera kwa camshaft kumayambitsidwa ndi zifukwa zaumunthu, makamaka pamene injini ikukonzedwa, camshaft sichimaphwanyidwa bwino ndikusonkhanitsidwa. Mwachitsanzo, pochotsa chivundikiro cha camshaft, gwiritsani ntchito nyundo kuti mugwetse pansi kapena kupukuta ndi screwdriver, kapena kuyika chivundikirocho pamalo olakwika, zomwe zimapangitsa kuti chivundikirocho zisagwirizane ndi mpando wonyamula, kapena torque yomangirira. zomangira zomangira mabawuti ndi zazikulu kwambiri. Mukayika chivundikirocho, tcherani khutu ku mivi yolowera ndikuyika manambala pamwamba pa chivundikirocho, ndipo gwiritsani ntchito wrench ya torque kuti mumitse mabawuti omangira chivundikirocho motsatira makokedwe omwe atchulidwa.
