Wide-angle belts (also called high-wedge-angle V-belts), with their large wedge angle design and flexible belt structure, combine the high friction of V-belts with the smoothness of synchronous belts. Their core advantage is their compatibility with small-diameter pulleys and improved transmission efficiency, making them particularly suitable for medium- and low-power transmission applications where space is limited.

Product Advantages

Compatible with small-diameter pulleys: The wedge angle is typically 60° (compared to approximately 40°-45° for conventional V-belts). The thinner and more flexible belt body allows for a tight fit around pulleys with smaller diameters (down to 10mm), significantly saving space in the transmission system.

Higher Transmission Efficiency: The large wedge angle design ensures a more even contact area between the belt and pulley, resulting in more balanced friction distribution and less slippage. Transmission efficiency can reach 95%-98%, 2%-3% higher than conventional V-belts of the same specification.

Smoother and quieter operation: The belt body is often constructed of a composite structure of rubber and high-strength fiber, offering excellent flexibility, low vibration and noise during operation, and minimizing impact on equipment components. Strong Weather and Wear Resistance: The surface is often covered with oil-resistant and age-resistant rubber or polyurethane. It operates in temperatures ranging from -20°C to 100°C and in lightly oily environments, with a service life 15%-20% longer than conventional narrow V-belts.
