PU round belt, a kind of belt, forms a round belt drive together with the pulley. Round belt drive is a kind of friction drive. Round belt, also known as PU round belt and connectable round belt, is usually made of PU. Pu is the abbreviation of polyurethane, which is called polyurethane in Chinese.
working principle
PU round belt transmission is friction belt transmission. The transmission belt is tightly sleeved on the two pulleys to generate pressure between the belt and the contact surface of the pulley. When the driving wheel rotates, the friction between the belt and the contact surface of the driving wheel makes the belt move. At the same time, the belt drives the driven wheel to rotate by the friction between the belt and the contact surface of the driven wheel, so as to transmit motion and power.
Application of PU round belt
PU round belt is applied to round belt transmission. The round belt transmission generates friction by pressing the belt and the wheel groove, which has good elasticity. It can alleviate the impact and vibration during operation, with stable movement and low noise. When the load is too large, the belt slips to protect the machinery. Circular belt drive is used in low-speed and low-power transmission, such as sewing machine, tape drive and other small power or manual machinery.
