<p>The object of the invention is a torsional vibration damping unit in the driving system of a reciprocating diesel engine intended for the limitation of the amplitude of torsional vibration transferred between the engine main shaft and auxiliary mechanisms such as fuel injection pump, timing gear, oil or water pump, by intermediary of flexible shafts. The invention is characterised in that the vibration damper (3) of the main shaft (4) is mounted on this shaft (4) near the power take-off area (5) and that simultaneously on the injection pump coupling (7) an additional damper (6) is fitted, mating with the vibration damper (3) of the main shaft (4), the gear oil pump (1) being provided with the gears having oblique teeth. As a vibration damper (3) of the main shaft (4), a known viscous damper is mounted, while as an additional damper (6), on the injection pump coupling (7), a known friction damper is fitted. The construction of a torsional vibration damping unit according to the invention allowed to restrict effectively the destructive action of torsional vibration on the driving transmission of fuel injection pump and other mechanisms of the engine.</p> |
