A drive belt is a flexible, continuous band used to transmit power from a motor to the drive wheel in band saws or other power tools. Drive belts can be made of rubber, leather, or synthetic materials, and may feature various profiles, such as V-belts, flat belts, or toothed belts. Proper tension and alignment of the drive belt are essential for maintaining smooth, consistent power transmission, minimizing vibration, and prolonging the life of the belt and other machine components.
