The main characteristics of synchronous belt transmission are: ① accurate transmission ratio, high transmission efficiency, low initial tension, and low force on the shaft; ② Large transmission ratio and linear speed range; ③ Instantaneous velocity uniformity; ④ The power transmitted per unit mass is relatively large; ⑤ It can freely change gears, has a simple structure, is easy to replace, and is suitable for transmission situations with large center distance between two axles; ⑥ Smooth and noise free transmission, capable of buffering and absorbing vibration; ⑦ Equipped with overload protection function, it can prevent damage to weak components and provide safety protection.
The main applications of glass production lines include: transmission of roller tables, transmission of acceleration and deceleration roller tables, movement of the cutting head box of the cross cutting machine, transportation of the slicing machine, and movement of the entire horizontal stacking machine.
Synchronous belts have various advantages such as high transmission power, smooth operation, low working noise, and no need for lubrication. In terms of selection, different belt types should be selected according to the different usage requirements of glass machinery. When high transmission efficiency, accurate transmission ratio, and low transmission shaft force are required, trapezoidal toothed synchronous belts are generally preferred. When the transmission power is large and the wear of the belt and belt teeth is reduced, more circular toothed belts are used. The selection mainly depends on the following usage requirements: transmitted power, transmission torque, transmission ratio, transmission or conveying speed, transmission or conveying frequency, conveying items, usage environment, service life, replacement conditions, etc.
For example, in the transmission of cold end rollers on glass production lines, the requirement for the transmission belt is high. Although it does not have lubrication conditions, it requires smooth operation, low speed, low torque required, low noise, and certain wear resistance. So it is necessary to be able to transmit the set power and precise transmission ratio, while also ensuring durability and long service life. Choosing a rubber arc toothed synchronous belt can greatly improve its working performance.
