A sprocket, comprising:
- radially directed sprocket teeth forming a plurality of gullets, wherein each gullet is configured to receive a tang of a center link;
- and
- support rims coaxially disposed on each side of the radially directed sprocket teeth, wherein the support rims include a plurality of facets configured to support a cutter link as the cutter link traverses the sprocket and engages a sharpening element.
A cutting system comprising:
- a cutting chain, wherein the chain is configured to engage a guide bar and a chainsaw drive sprocket, wherein the chainsaw drive sprocket comprises:
- radially directed sprocket teeth forming a plurality of gullets, wherein each gullet is configured to receive a tang of a center link;
- and
- support rims coaxially disposed on each side of the radially directed sprocket teeth, wherein the support rims include a plurality of facets configured to support a cutter link as the cutter link traverses the sprocket and engages a sharpening element;
- a sharpening element disposed proximal to the cutting chain;
- and
- an actuator coupled to the sharpening element and adapted to selectively urge the sharpening element into contact with the cutting chain.
