The driving device of a belt conveyor is a marvel of engineering, featuring an electric motor, coupling or hydraulic coupling, reducer, and transmission drum. These components work harmoniously to propel the belt conveyor, transforming gravitational force into movement through friction, thus enabling the seamless transportation of goods. In cases where the conveyor includes inclined sections, brakes or backstops are essential to maintain control. Dive into an enlightening exploration with our article 'Specific Applications and Analysis of Advantages and Disadvantages of 9 Drive Devices for Belt Conveyors, Help You Choose the Right One.' Most belt conveyors traditionally utilize a single drum drive, yet as the demands for capacity and transportation distance surge, the traction force transmitted by the drive drum scales accordingly. This evolution has led to the innovation of double drum and multi drum drive systems. Each transmission drum can accommodate one or two drive units, seamlessly integrating with the drive unit through a coupling at the end of the transmission drum shaft. Typically, Y-series cage type motors are employed due to their compact size, cost-effectiveness, reliable operation, and ease of automation. For small power applications (≤ 37kW), an elastic coupling suffices for direct drive. However, in situations demanding higher power (45-315kW), a hydraulic coupling ensures a smooth start-up. When faced with high power requirements (220-800kW), a wound motor becomes the ideal choice, offering easy regulation and facilitating the smooth operation of long-distance belt conveyors, effectively balancing power across multiple drum drives. Modern large-scale belt conveyors frequently utilize bevel gear reducers to minimize the lateral size of the conveyor drive device. For mobile belt conveyors, weight reduction is a priority, thus opting for belt, chain, or first stage open gear transmission is common. Additionally, options like a cycloidal pinwheel reducer or an electric drum can be employed to enhance efficiency and performance.
