Ma crankshaft pulleys a injini yamagalimoto ndi ma torsional vibration dampers amayikidwa kumapeto kwa crankshaft. Yoyamba imagwiritsidwa ntchito kuyendetsa zinthu monga mapampu amadzi ozizira, ma jenereta, ndi ma compressor a air-conditioning, ndipo omalizawa amagwiritsidwa ntchito kuchepetsa kugwedezeka kwa crankshaft.

The crankshaft kwenikweni ndi shaft yokhala ndi kukhuthala kwina ndi kulemera kozungulira, chomwe ndi chifukwa cha kugwedezeka kwapang'onopang'ono kwa crankshaft. Panthawi yogwiritsira ntchito injini, kukula ndi kayendetsedwe ka mphamvu zomwe zimatumizidwa ku crankshaft kudzera pa ndodo yolumikizira zimasintha nthawi zonse, kotero kuti kuthamanga kwapang'onopang'ono kwa crankshaft kumasintha mosalekeza. Izi zipangitsa kuti crankshaft itembenuke mwachangu kapena pang'onopang'ono pokhudzana ndi gudumu la ndege, zomwe zingayambitse kugwedezeka kwa crankshaft. Kugwedezeka kotereku kumawononga kwambiri ntchito ya injini, ndipo kunjenjemera kukachitika, kumakulitsa kugwedezeka kwa injini. Chifukwa chake, njira zochepetsera kugwedezeka ndi kunyowetsa ziyenera kuchitidwa. Chothandiza kwambiri ndikuyika chotsitsa chotsitsa cha torsional vibration kumapeto kwa crankshaft.

Ma dampers ogwiritsidwa ntchito kwambiri a crankshaft torsional vibration pamainjini amgalimoto ndi ma frictional torsional vibration dampers, omwe amatha kugawidwa mumtundu wa rabara wa crankshaft torsional vibration dampers ndi zotsitsa mafuta a silicone torsional vibration. Zomwe zimagwiritsidwa ntchito nthawi zambiri ndi rabara zamtundu wa crankshaft torsional vibration dampers, monga momwe zilili pansipa.

Pakadali pano, chowongolera cha crankshaft torsional vibration chomwe chimagwiritsidwa ntchito mu injini zamagalimoto onyamula anthu nthawi zambiri sichimaperekedwa ndi inertia disc yokha. M'malo mwake, crankshaft pulley imagwiritsidwanso ntchito ngati inertia disc. Pulley ndi shock absorber amapangidwa kukhala thupi limodzi, lomwe limatchedwa vibration damping pulley. Pofuna kuonetsetsa kusinthasintha kwa crankshaft ndi nthawi ya sitima ya valve, kawirikawiri, pulley ya crankshaft imakhala ndi dial angle ya crankshaft ndi nthawi. chizindikiro ndi kuyatsa patsogolo ngodya.
