Sprocket and idler sharing common wheel

1. A wheel kit comprising:

a common wheel member defining a longitudinal axis, a radial direction, and a circumferential direction;

a first annularly configured attachment; and

a second annularly configured attachment;

wherein the second annularly configured attachment includes a common ring member that is the same as that of the first annularly configured attachment, defining the same inside diameter except that the first annularly configured attachment includes teeth, while the second annularly configured attachment lacks teeth, and both the first annularly configured attachment and the second annularly configured attachment are configured to be attached to the common wheel member.

2. The wheel kit of claim 1 wherein the common wheel member includes an inner radial hub, an outer radial support flange, and a web connecting the inner radial hub to the outer radial support flange.

3. The wheel kit of claim 2 wherein the web defines a plurality of apertures extending longitudinally through the web and the inner radial hub defines a central aperture extending longitudinally through the inner radial hub.

4. The wheel kit of claim 3 wherein the common wheel member is a unitary forged piece of material.

5. The wheel kit of claim 2 wherein the first annularly configured attachment is a toothed annular attachment that is configured to be attached to the outer radial support flange.

6. The wheel kit of claim 5 wherein the toothed annular attachment defines an inner radial surface, the outer radial support flange defines an outer radial surface, and the inner radial surface is configured to engage the outer radial surface.

7. The wheel kit of claim 6 wherein the toothed annular attachment is press-fit or interference fit onto the common wheel member.

8. The wheel kit of claim 7 wherein the toothed annular attachment comprises a different material than the common wheel member, the toothed annular attachment is differently heat treated than the common wheel member, or the toothed annular attachment is differently coated than the common wheel member.

9. The wheel kit of claim 2 wherein the second annularly configured attachment is an idler flange annular attachment that is configured to be attached to the outer radial support flange.

10. The wheel kit of claim 9 wherein the idler flange annular attachment includes defines an inside radial surface, the outer radial support flange defines an outer radial surface, and the inside radial surface is configured to engage the outer radial surface.

11. The wheel kit of claim 10 wherein the idler flange annular attachment is press-fit or interference fit onto the common wheel member.

12. The wheel kit of claim 11 wherein the idler flange annular attachment comprises a different material than the common wheel member, the idler flange annular attachment is differently heat treated than the common wheel member, or the idler flange annular attachment is differently coated than the common wheel member.

13. A sprocket and an idler sharing a common wheel member manufactured by a method, the method comprising:

providing the common wheel member;

providing an idler flange annular attachment; and

providing a toothed annular attachment;

wherein providing the idler flange annular attachment and providing the toothed annular attachment includes providing the idler flange annular attachment that is identically configured to the tooth annular attachment except that the idler flange annular attachment lacks teeth.

14. The sprocket and the idler sharing the common wheel member manufactured according to the method of claim 13 , the method further comprising attaching either the idler flange annular attachment or the toothed annular attachment circumferentially to the common wheel member.

15. The sprocket and the idler sharing the common wheel member manufactured according to the method of claim 14 wherein attaching is accomplished via a press-fit or interference fit.
