Clearance adjustable viscous damper for torsional vibration of engine crankshaft system

摘要

The invention particularly relates to a precise interval adjustable engine shafting torsional viscous damper, cylindrical case of 2 according to the inertia ring, high-viscosity silicone oil and engine shaft torsional viscous damper consisting of the case cover, and the second of the male screw formed on the outer peripheral surface of the outer cylinder opening of the cylindrical case, the case cover is formed in a cap shape, but, in the case cover inner surface of the outer blade forms a male screw and a female screw screw coupled to the cylindrical case of the outer cylinder 2, the inside of the cylindrical case 2, between the contact end and the outer cylinder and the inner circumferential surface of the case cover is installed an O-ring, of the second lateral wings on the outer cylinder of the cylindrical case 1 and the case cover is coupled to the screw drive inside the cylindrical case 2 by the number of the bolts, characterized in that fixed to the outer cylinder. ; In this way the engine Torsional vibration of the shaft 2 and the inertia ring by a cylindrical case which is coupled to the cover case of the viscous damper so as to disassemble the assembly from the non-stationary changes of the case cover tightness can determine the performance of the damper between its use for reduction is the viscosity of the damper itself can freely control interval that can significantly reduce the torsional vibration damper of the engine shaft to the power generated by the relative movement between the case and the inertia ring when installed on the free end of the engine crankshaft.
