Injini yemotokari crankshaft pulleys uye torsional vibration madhamu akaiswa kumberi kumucheto kwe crankshaft. Iyo yekutanga inoshandiswa kutyaira zvinhu zvakaita sekutonhodza pombi dzemvura, jenareta, uye air-conditioning compressors, uye yekupedzisira inoshandiswa kudzikisa torsional vibration ye crankshaft.

Iyo crankshaft ichokwadi shaft ine imwe elasticity uye inotenderera huremu, ndicho chikonzero chekuzununguka kweiyo crankshaft. Munguva yekushanda kweinjini, ukuru uye kutungamira kwesimba rinopfuudzwa ku crankshaft kuburikidza netambo yekubatanidza inogara ichichinja, zvekuti iyo pakarepo angular velocity ye crankshaft inoshandukawo ichienderera. Izvi zvinokonzeresa kuti crankshaft itenderere nekukurumidza kana kunonoka hama kune flywheel, izvo zvinokonzeresa torsional vibration ye crankshaft. Kudengenyeka kwerudzi urwu kunokuvadza zvakanyanya kubasa reinjini, uye kana resonance ikangoitika, inowedzera kuzununguka kweinjini. Naizvozvo, kuderedza vibration uye matanho ekunyorovesa anofanirwa kutorwa. Iyo inonyanya kushanda ndeyekuisa torsional vibration damper kumucheto kumberi kwe crankshaft.

Iwo anonyanya kushandiswa crankshaft torsional vibration dampers einjini dzemotokari ndeye frictional torsional vibration dampers, iyo inogona kupatsanurwa kuita rabha mhando crankshaft torsional vibration dampers uye silicone oiri torsional vibration dampers. Inowanzo shandiswa ndeye rubber-type crankshaft torsional vibration dampers, sezvinoratidzwa pasi apa.

Parizvino, crankshaft torsional vibration damper inoshandiswa mumainjini emotokari yevafambi haiwanzo kupihwa ine inertia disc chete. Pane kudaro, crankshaft pulley inoshandiswawo se inertia disc. Iyo pulley uye shock absorber inogadzirwa kuita muviri mumwe, unonzi vibration damping pulley.Kuitira kuve nechokwadi kutenderera kwe crankshaft uye nguva yechitima chevhavha, kazhinji, crankshaft pulley ine crankshaft angle dial ine nguva. mucherechedzo uye kona yekubatidza mberi.
