Ama-crankshaft pulleys enjini yemoto kanye namadampers e-torsional vibration afakwe ngaphambili ekugcineni kwe-crankshaft. Eyangaphambili isetshenziselwa ukushayela izesekeli ezifana namaphampu amanzi okupholisa, amajeneretha, nama-compressor air-conditioning, kanti eyakamuva isetshenziselwa ukunciphisa ukudlidliza kwe-torsional ye-crankshaft.

I-crankshaft empeleni iyi-shaft ene-elasticity ethile nesisindo esijikelezayo, okuyisizathu sokudlidliza kwe-torsional ye-crankshaft. Ngesikhathi sokusebenza kwenjini, ubukhulu nesiqondiso samandla adluliselwe ku-crankshaft ngenduku yokuxhuma kushintsha njalo, ukuze isivinini esisheshayo se-angular ye-crankshaft nayo ishintshe ngokuqhubekayo. Lokhu kuzobangela ukuthi i-crankshaft ijikeleze ngokushesha noma kancane ngokuhlobene ne-flywheel, okuzobangela ukudlidliza kwe-torsional ye-crankshaft. Lolu hlobo lokudlidliza luyingozi kakhulu emsebenzini wenjini, futhi uma kuvela i-resonance, kuzoshubisa ukuzamazama kwenjini. Ngakho-ke, kufanele kuthathwe izinyathelo zokunciphisa ukudlidliza kanye nokwehlisa umoya. Okusebenza kahle kakhulu ukufaka isidambisi manzi sokudlidliza ekugcineni kwe-crankshaft.

Amadampers e-crankshaft torsional vibration asetshenziswa kakhulu ezinjinini zezimoto amadampers okudlidliza okushayisanayo, angahlukaniswa abe uhlobo lwenjoloba lwe-crankshaft torsional vibration dampers kanye namadampers e-silicone torsional vibration. Okuvame ukusetshenziswa ama-dampers okudlidliza ohlobo lwerabha ku-crankshaft, njengoba kukhonjisiwe ngezansi.

Uhlobo lwerabha i-crankshaft torsional vibration damper

Okwamanje, i-crankshaft torsional vibration damper esetshenziswa ezinjinini zezimoto zabagibeli ngokuvamile ayihlinzekwa nge-inertia disc iyodwa. Esikhundleni salokho, i-crankshaft pulley nayo isetshenziswa njenge-inertia disc. I-pulley kanye ne-shock absorber kwenziwa umzimba owodwa, obizwa ngokuthi i-vibration damping pulley.Ukuze uqinisekise ukujikeleza kwe-crankshaft kanye nesikhathi sesitimela se-valve, ngokuvamile, i-crankshaft pulley inokudayela kwe-crankshaft angle enesikhathi. umaka kanye ne-engeli engaphambili yokuthungela.
