The working principle of industrial conveyor belts
Industrial transmission belts primarily transmit power through friction or meshing and are divided into two main categories: friction-type belts (such as V-belts and flat belts) and meshing-type belts (such as synchronous belts). The core principles underlying these belts are as follows:
Friction-type belt drive
Power is transmitted by the friction between the belt and the pulleys. The driving pulley transmits power to the belt via friction, and the belt in turn drives the driven pulley. To maintain sufficient friction, tensioners or adjustments to the shaft distance are required. Its advantages include a simple structure and low cost; however, it suffers from issues such as slippage and an inconsistent transmission ratio.
Synchronous belt drive
Driven by the meshing engagement between the belt teeth and the pulley grooves, this transmission features no slippage, a constant transmission ratio, and an efficiency as high as 98%. It is ideal for high-precision applications (such as robotics and medical equipment), offering smooth operation and simple maintenance.
Key difference
Accuracy: Synchronous belts ensure a constant transmission ratio through toothed engagement, whereas friction-type belts cannot achieve this due to slippage.
Efficiency: Synchronous belts have energy losses of only 2%, whereas friction-type belts suffer losses ranging from 15% to 30%.
Applications: Synchronous belts are used in precision equipment, while friction-type belts are suitable for general machinery.
