Trapezoidal power transmission belt

rubber

Higher power transmission by continuous and uniform cord. A larger contact surface than V belts. Technical studies have revealed that at the same tension and with the same geometry the Poly V compared to V-Belt has an upper yield : it is situated on average around 98 %, a fact that reduces electricity consumption and the size of the motor. Higher transmission ratio Ribbed belt 1: 60 vs V belt 1: 20. Avoids the need for staged pulleys. Reduced diameter of the pulleys The minimum diameters of ribbed profiles are smaller than those of V-Belt profiles. Reduced weight of the transmission No need for a tensioner. Reduced belt width for a given geometry and the same power transfer (small ribbed pulley). Moreover, the Poly V can operate in flexion and counter flexion with the following benefits: A single belt can drive several accessories: serpentine belt installation. Driving accessories from the back of the belt.
