Some problems need to know in the selection of synchronous belt

Author:


Synchronous belt drive is a combination of belt drive, chain drive and gear drive advantages of transmission. It also has the advantages of friction belt transmission, can maintain a constant transmission ratio, and has a simple structure, a stable transmission system, can buffer and absorb vibration, and can transmit development power between large shaft spacing and multiple shafts. The utility model has The advantages of low cost, no lubrication, convenient maintenance, etc., the working surface of the timing belt is toothed, A meshing transmission device that transmits motion and power is realized through multi-tooth meshing between belt teeth and belt teeth. Compared with the traditional belt drive, chain drive, and gear transmission system, in the synchronous toothed belt drive, the working horizontal surface of the synchronous belt has teeth, and the largest surface of the pulley rim is also made with corresponding tooth grooves, relying on the belt and the pulley. There is no sliding between meshing transmission and power transmission, ensuring a constant transmission ratio and low preload.

Through years of development, the variety of synchronous belts has increased many kinds, various ways of different material problems and different tooth types have provided different characteristics for synchronous belts, which can meet the needs of various products. In actual use, according to the working conditions of the product. Choosing the right timing belt, in order to improve product safety and market competitiveness under satisfactory conditions, it is very important to achieve the best economy under working conditions.

With the continuous development of mechanical and electronic equipment to high precision, high speed, high power, long life, low noise and compact direction, the belt drive system technology has put forward more and higher standards. The constant updating of the tooth profile also provides designers with more and better choices. The selection of synchronous belt should be based on several important requirements. The shape, material, vibration and load of the gear are integrated in the key performance such as transmission accuracy, carrying capacity, service life, noise and speed. Consider, choose the most suitable synchronous belt.
