Isidambisi se-Torsional vibration
Ama-dampers we-Torsional vibration aklanyelwe ukudambisa ukudlidliza kwe-crankshaft okwenzeka ngesikhathi somlilo. Zitholakala ekugcineni kwamahhala kwe-crankshaft kanye ne-drive pulley yezinsiza zenjini (i-alternator, i-air conditioning compressor, i-servo drive, njll.).
Ngesikhathi sokusha kukaphethiloli, amandla womthelela wobukhulu obuhlukile nobuningi benza ku-crankshaft, ukuze i-crankshaft idlidlizelele ngokweqile. Uma ukudlidlizela okubangelwe ngale ndlela kwesinye isivinini esibizwa ngokubucayi sokujikeleza kuhambelana nokudlidliza kwemvelo kokhakhayi, kukhona lokho okubizwa ngokuthi i-resonance, futhi nomgodi ungadlidlizela uze ufike ephukeni. Kufanele kukhunjulwe ukuthi indlela nokuqina kokudlidliza kunqunywa ukwakhiwa kwempahla yomshini. Ukuqeda lokhu kudlidliza okungafuneki, i-torsional vibration damper, evame ukutholakala ekugcineni kwamahhala kwe-crankshaft, iyasebenza.
Uquqaba lokudambisa (i-inertia) lwesidambisi sokudlidliza kwe-torsional luxhunywe nge-elastically ku-drive disc yiringi yenjoloba eyomayo. Idrayivu yediski inamathele ngokuqinile ku-crankshaft. Uma i-crankshaft iqala ukudlidliza ngokweqile, lokhu kudlidliza kuncishiswe yi-inertia yesisindo sokudambisa, esikhubaza irabha elincane. Esikhundleni senjoloba, i-high-viscosity silicone oil kwesinye isikhathi iyasetshenziswa, bese kuthi i-torsional vibration damper ibizwe nge-viscous.
