‌Wedge groove design‌:
The wheel surface has equidistant longitudinal grooves (such as PJ, PK and other models), which fit tightly with the raised wedge structure of the multi-V belt, increasing the contact area, improving transmission efficiency and friction.
‌Mechanical advantages‌:
Compared with traditional flat belts or V-belts, multi-wedge pulleys can transmit greater torque, higher belt speeds, and a transmission ratio of up to 7. They also have good flexibility and strong vibration resistance.

Application areas

‌General industrial equipment‌:
Power transmission systems of packaging machinery, textile equipment, and printing machinery1112;
Synchronous transmission in automated production lines, such as conveyor roller systems (to improve load capacity and environmental adaptability)12.
‌Heavy load scenarios‌:
High torque transmission of mining machinery (crushers, ball mills), metallurgical equipment (rolling mills)11;
Increase mechanism of wind power equipment, automotive power system (drive motor control of new energy vehicles)11.
‌Precision transmission‌:
CNC machine tool spindle transmission, high-precision synchronous pulley customization (support 3M/5M/8M and other tooth types)
