Abstract
In a chain transmission using a hybrid chain having inner and outer links with bushings, or with bushings and rollers, the rollers mesh with a central sprocket, and the link plates have teeth that function as a silent chain, meshing with side sprockets fixed to the central sprocket. The teeth of the link plates of the inner links have a shape different from that of the teeth of the link plates of the outer links. The outer flanks of the teeth can all have the same shape, and the shape difference can be in the shapes of the inner flanks.
