How to choose the right belt and pulley?
• Select the appropriate belt for the design torque. • Select the appropriate belt material for the environment (temperature, chemical, cleaning agents, oils and weather). Belt-and-pulley systems are suitable for myriad environments, but some applications need special consideration. Topping this list are environmental factors.
What are the dimensions of a carbon belt pulley?
It leverages new materials and geometries, with nine carbon cords embedded within engineered polymer belt and an 11-mm tooth pitch profile for lower tension. It replaces chain drives. Manufacturers generally describe belts and pulleys with five main geometries. Pitch diameter is the drive pulley’s diameter.
What are the forces that work on a pulley?
The forces that work during operation are not uniform around the entire belt length; there is always a tight side tension and a slack side tension. The difference between these tensions is often called by belt manufacturers the effective or net pull. This effective pull is applied at the rim of the pulley and is the force that produces work.
What should I do if my pulley has run out?
If the pulley is mounted on a tapered shaft bushing, inspect and clean the bushing both inside and out to ensure proper seating. Now check for face (axial) run-out and, if necessary, correct it by repositioning the pulley on its shaft. When run-out is in tolerance, proceed to install new belts. Drive Belt Fitting

What makes a belt make a chirping noise?
Most chirp noises occur as a short belt span enters into a grooved pulley, typically after exiting a backside pulley. Contamination (oil, power steering fluid, antifreeze, belt dressing, brake cleaner, etc. Inspect and replace all accessories / pulleys that are difficult to rotate (i.e. rough/seized bearings), or show excessive wobble / free rock
Why do belt pulleys make so much noise?
Noise frequency increases proportionally with belt speed, and noise amplitude increases with belt tension. Most belt noise arises from the way in which belt teeth entering the pulleys at high speed repeatedly compresses the trapped pockets of air.
