A system of flexible bands and grooved wheels transmits rotational motion and power between shafts. This arrangement is commonly used in a wide range of machinery, from automotive engines to industrial conveyors, enabling efficient power transfer across varying distances and speeds. For instance, a car’s serpentine belt drives components like the alternator, power steering pump, and air conditioning compressor.
This method of power transmission offers several advantages, including simplicity, low cost, and the ability to absorb shock and vibration. Historically, belts and pulleys played a crucial role in the Industrial Revolution, powering looms and other machinery. Their continued relevance in modern engineering testifies to their practicality and adaptability.
