Tensioners and idler gears found in the timing belt or chain configuration or with many drive belts. 

Belt Tensioner

Timing belts (also known as toothednotchcog, or synchronous belts) are a positive transfer belt and can track relative movement. These super strong belts are designed with teeth that fit into a matching toothed pulley. When correctly tensioned, they have no slippage, run at constant speed, and are often used to transfer direct motion for indexing or timing purposes. They are often used instead of chains or gears, so there is less noise and a lubrication bath is not necessary. Camshafts of automobiles, miniature timing systems, and stepper motors often utilize these belts. Timing belts need the least tension of all belts and are among the most efficient. They do however need to be replaced at specific service intervals that are usually shorter than chain drives.

Timing belts with a helical offset tooth design are available. The helical offset tooth design forms a chevron pattern and causes the teeth to engage progressively. The chevron pattern design is self-aligning and does not make the noise that some timing belts make at certain speeds, and is more efficient at transferring power (up to 98%).

Driving your car

Specific sizes need to be purchased and the number of teeth on the belt need to be exact and cannot change in any way.
