ABSTRACT:
A chain drive sprocket formed of a plurality of sprocket segments arranged seriatim alternately to define a continuous equiangularly spaced annular series of sprocket teeth with a first group of the sprocket segments having a different number of teeth from the alternating second group. Each of the segments may have a similar number of mounting bolt holes, which, in the circular sprocket arrangement, are equiangularly spaced about the axis of the sprocket. The sprocket segments are of different angular extent and the end bolt holes of different sprocket segments may be spaced differently from the end surfaces of the sprocket segments. The sprocket radii centered between opposed adjacent end surfaces may be angularly spaced from the radial centerline through the root between the end teeth of the sprocket segments at opposite sides of the adjacent end surfaces.
