Abstract
A sprocket assembly comprising replaceable outer tooth segments configured for attachment to an inner hub assembly. The inner hub assembly is securable to an input shaft of a machine. Each outer tooth segment is securely fastened to the inner hub via high-strength Huck fasteners. This segmented tooth design allows for selective replacement of worn or damaged teeth without requiring replacement of the entire sprocket assembly.

A sprocket assembly comprising:
- an inner hub having a shaft opening, wherein the inner hub includes hub dovetails extending radially outwards;
- outer tooth segments mounted on and surrounding the inner hub, wherein the plurality of outer tooth segments includes outer dovetails extending radially inwards, and wherein each outer tooth segment is directly adjacent with another outer tooth segment;
- and
- wherein the hub dovetails and the outer dovetails have an interlocking configuration such that the outer tooth segments lock to the hub dovetails of the inner hub both radially and circumferentially.

A sprocket assembly comprising:
- an inner hub having a shaft opening, wherein the inner hub includes hub dovetails extending radially outwards;
- outer tooth segments mounted on and surrounding the inner hub, said outer tooth segments includes outer dovetails extending radially inwards wherein the outer dovetails are configured to lock radially with the hub dovetails;
- said outer tooth segments include webs, wherein the outer dovetails and the webs define recesses that correspond to the shape of the hub dovetails;
- and
- fasteners configured to extend through each hub dove tail and each webs of the outer tooth segments, wherein said fasteners compress the inner hub and outer tooth segments together.
