Sprocket

摘要

A sprocket includes first teeth having a first maximum width, and second teeth having a second maximum width greater than the first maximum width alternately arranged with the first teeth. The second teeth have a leading surface relative to a drive direction of the sprocket, a lateral surface at the second maximum width, a relief between the leading surface and the lateral surface, and a relief cut in the relief, with a midline of the lateral surface being offset relative to a plane extended radially through a center of a respective tooth.

1. A sprocket, comprising:
teeth radially projecting from a body, the teeth including first teeth having a first maximum width and second teeth having a second maximum width greater than the first maximum width alternately arranged with the first teeth, the sprocket to rotate in a drive direction about a rotational axis, and the second teeth being asymmetrical about a plane extended radially from the rotational axis, the second teeth having a drive-side surface relative to the drive direction, a lateral surface at the second maximum width, a drive-side relief comprising a chamfer between the drive-side surface and the lateral surface, and a drive-side relief cut formed in the chamfer of the drive-side relief.
