Abstract

A chain transmission system having a drive sprocket, a driven sprocket, a chain having a front side engaging teeth on the drive sprocket and teeth on the driven sprocket, and a rotary wheel having rubber outer surface. A backside of the chain engages the rubber outer surface of the driven wheel.

Claims

1. A chain transmission systems wherein one portion of elements engage a front side of a chain used is such system and another portion of elements in the system chain have a rubber outer surface engaging a back side of the chain.

2. The chain system recited in claim 1 wherein the rubber outer surface is toothless.

3. The chain system recited in claim 1 wherein the first mention portion of elements includes a drive sprocket and a driven sprocket.

4. The chain system recited in claim 3 wherein the chain has a front side engaging teeth on the drive sprocket and teeth on the driven sprocket.

5. The chain system recited in claim 4 wherein the rubber outer surface is toothless.

6. The chain system recited in claim 5 wherein the drive sprocket has metal teeth and wherein the chain has a front side engaging the metal teeth on the drive sprocket.

7. The system required in claim 6 wherein the wheel has a metal inner portion and wherein the rubber is disposed about the outer portion of the inner portion.

8. A chain transmission system, comprising:

a drive sprocket;

a driven sprocket;

a chain having a front side engaging teeth on the drive sprocket and teeth on the driven sprocket;

an rotary wheel having rubber outer surface; and

wherein a backside of the chain engages the rubber outer surface of the driven wheel.

9. The system recited in claim 8 wherein the drive sprocket is metal and wherein the chain is metal.

10. The system required in claim 8 wherein the wheel has a metal inner portion and wherein the rubber is disposed about the outer portion of the inner portion.

11. The system recited in claim 8 wherein the drive sprocket is driven by a drive shaft of an internal combustion engine and wherein the driven sprocket is attached to a camshaft of the engine.

12. The system recited in claim 10 wherein the drive sprocket is driven by a drive shaft of an internal combustion engine and wherein the driven sprocket is attached to a camshaft of the engine.

13. The chain system recited in claim 12 wherein the rubber outer surface is toothless.
