Friction Belts

Friction belts (or V-belts and flat belts) are simple loops of strong, flexible material used to connect two rotating wheels (called pulleys) and transfer power.
Here is the simple breakdown:
• Uses Grip (Friction): They work by gripping the pulleys tightly. The tighter the grip (friction), the more power they can move without slipping.
• Smooth and Quiet: They are much quieter and run smoother than noisy metal gears or chains.
• Easy to Replace: If the system is overloaded, the belt will harmlessly slip or break, which is easier and cheaper to replace than a gear or chain system.
• Found Everywhere: They are commonly used in washing machines, car engines (serpentine belts), vacuum cleaners, and industrial fans.
In short, a friction belt is a smooth, flexible rubber or leather loop that uses grip to quietly turn one wheel using the power from another.
