Abstract
A torsional vibration damping apparatus, especially a web damper for mounting on a crankshaft of a piston engine, particularly an internal combustion engine for suppression of natural torsion frequencies from crankshafts can now be economically produced. The apparatus comprises a housing fastened to the engine crankshaft to which at least one rotary mass is coupled with spring elements disposed between the housing and the rotary mass allowing the apparatus to be pre-assembled. Advantageously, multiple parts of the torsional vibration damping apparatus, such as the housing can now be fabricated from more economic sheet metal in place of more costly cast parts.
Claims18
A torsional vibration damping apparatus arranged to be mounted on a crankshaft of a piston engine comprising a housing having at least a housing base and a housing cover, said damping apparatus further comprising at least one metal flywheel mass arranged for mounting between said housing base and said housing cover, and a plurality of compression spring held in place by said housing base and said housing cover, said compression springs arranged to couple said flywheel mass to said housing, wherein at least said housing base and said housing cover are formed from sheet metal.
