  • A RIM -TYPE ABRASION CUTTER DRIVE SPROCKET, A DRIVE ARRANGEMENT, AN ABRASION CUTTER AND A METHOD OF DRIVING AN ABRASION CUTTING CHAIN OF AN ABRASION CUTTER
    Publication number: 20230001603
    Abstract: A rim-type abrasion cutter drive sprocket (24) for driving an abrasion cutting chain (16) of an abrasion cutter (10) comprises a set of sprocket teeth, which extend radially away from the drive sprocket's rotation axis (A), and define drive link gaps between them for receiving and drivingly engaging with drive links (26) of the cutting chain (16), and a pair of rim edges (44) which are concentric with and extend about the rotation axis (A) on either side of the drive link gaps, the rim edges (44) being configured to radially support side links (28) of the cutting chain (16). The rim edges (44) have a non-circular envelope, as seen along the rotation axis (A).
