Rubber Timing Belts

A rubber timing belt, rubber timing chain or rubber cam belt is a part of an internal combustion engine that controls the timing of the engine's valves. The term "rubber timing belt" is also used for the more general case of any flat belt with integral teeth. Such rubber timing belts are used for power transmission or to interchange rotary motion and linear motion, where either high loads or maintaining a specific drive ratio are important. A common non-automotive application of rubber timing belt is in linear positioning systems. Such rubber timing belts have also been used in efforts to make a cleaner, lower-maintenance bicycle transmission, but have never become popular in this application. A rubber timing belt is typically rubber with high-tensile fibers.
