Drive belts are flexible loops made of rubber or other materials that transfer power between different components in machines and vehicles. They are commonly found in engines, where they connect the crankshaft to various accessories like the alternator, water pump, and air conditioning compressor. This helps ensure that these components operate efficiently and effectively. There are different types of drive belts, including serpentine belts, timing belts, and V-belts. Each type serves a specific purpose and is designed to handle different loads and speeds. Regular maintenance and inspection of drive belts are essential to prevent wear and potential breakdowns in machinery or vehicles.
