Explore the powerhouse behind belt conveyors: the robust driving device. This essential component comprises an electric motor, coupling or hydraulic coupling, reducer, transmission drum, and more. For belt conveyors with inclined sections, brakes or backstops are integral additions. The driving device masterfully transmits gravitational force through friction, setting the conveyor belt in motion to transport goods seamlessly. (Intrigued?

While a single drum drive is typically employed, the rising demand for greater capacity and longer transport distances has led to the adoption of double and multi-drum drives. Each transmission drum can boast one or two drive units, connected at the shaft end via a coupling. The favored Y-series cage type motors, known for their compact size, affordability, dependable performance, and ease of automation, are commonly used. For smaller power needs (≤ 37kW), direct drive via an elastic coupling suffices. However, for higher power (45-315kW), a hydraulic coupling ensures a smooth start-up. In scenarios of very high power (220-800kW), a wound motor is advantageous, offering easy regulation and facilitating the smooth initiation of long-distance belt conveyors, effectively managing power balance in multi drum drives. Beyond traditional cylindrical gear transmission, cutting-edge large-scale belt conveyors often incorporate bevel gear reducers to minimize the lateral footprint of the drive device. For mobile belt conveyors, weight reduction is key, often achieved through belt, chain, or first stage open gear transmission. Additionally, cycloidal pinwheel reducers or electric drums are viable options, enhancing the efficiency and adaptability of these vital machines.
