Knowledge of PU TIMMING belt
According to the material, the synchronous belt can be divided into chloroprene rubber and fiber rope synchronous belt, polyurethane and steel wire synchronous belt. According to the tooth shape, it is divided into two main categories: trapezoid tooth and arc tooth, and can be divided into single tooth synchronous belt and double face synchronous belt according to the tooth surface. Let’s let Xiaobian popularize the knowledge of polyurethane PU synchronous belt today.
The polyurethane PU synchronous belt is made of imported thermoplastic polyurethane and has high anti wear ability. All kinds of wire cores keep good movement ability in the transmission, and the production tolerance is small. In the production process, a layer of nylon is made on the tooth surface and / or the back of the tooth to ensure that the operating particularity of the special application is constant, and a layer of polyurethane can be thickened on the back of the belt to prevent corrosion or high load.
The synchronous belt drive is made up of a closed annular belt with equal spacing teeth and a corresponding pulley inside the inner surface. In motion, the teeth are meshing with the groove of the belt wheel to transfer motion and power. It is a kind of meshing transmission, so it has various advantages of gear transmission, chain transmission and peace belt transmission. Synchronous belt transmission with accurate transmission ratio, no slip difference, can obtain a constant speed ratio, precision transmission, smooth transmission, shock absorption, low noise, high speed ratio range, generally up to 1:10, the line speed up to 50m/s, high transmission efficiency, generally up to 98%-99%. The power of transmission is from several watts to hundreds of kilowatts. It is also suitable for multi axis transmission with small tension, no lubrication and no pollution, so it can work normally in cases where pollution and working environment are not allowed.
