Notice of Retraction: Meshing impact of dual meshing silent chain drive

Abstract

The dual meshing is presented in order to reduce the polygon movement and the silent chain mechanism is designed, which comprises the dual meshing silent chain and new kind of sprockets. At the beginning of a meshing circle, the inner straight tooth form of the silent chain engages with the sprocket form. At the middle of a meshing circle, both sides of the silent chain contact with the sprocket form. The dual meshing silent chain depends on its outer tooth flank to wind around the sprocket. The meshing impact of the dual meshing silent chain mechanism, the conventional silent chain mechanism, the silent chain mechanism with the conventional silent chain and involute sprockets is researched. The result shows that the initial contact point is changed and the meshing impact velocity coefficient is decreased if the dual meshing silent chain mechanism is adopted.
