Abstract
An improved drag chain sprocket comprising two spaced-apart discs on a hub with removable teeth bolted to the discs. The open design of the sprocket prevents build-up of abrasive materials between the sprocket and the chain. The mounting position of the teeth may be altered to utilize unworn surfaces, thereby extending the working life of the sprocket.
Claims10
A sprocket for a drag chain comprising:
- a hub adapted to be mounted on a supporting shaft,
- a pair of plates spacedly mounted on said hub to extend radially therefrom,
- a plurality of equiangularly spaced recesses formed in said plates inwardly from their peripheries with each recess comprising axially aligned portions formed one in each plate and each portion extending across the full width of the plate, said plates having radially oriented fastener receiving apertures opening into said recesses
- a plurality of individual teeth apertured for receiving fastener means,
- said teeth being mounted one in each of said recesses wtih the chain engaging portion spanning at least distance between the outside surfaces of said plates and providing at least one chain engaging surfaces along its sides, and
- fastener means for detachably mounting said teeth in said recesses,
- whereby when said chain engaging surface of a tooth is worn, it may be removed from the associated recess and replaced.
