When applied to a belt conveyor, the conveyor pulley has three main purposes: 1) assist the belt when changing direction on the conveyor, 2) transmit driving force to the belt, and 3) guide or train. group. The driving force on the conveyor belt can be located at the head or exit end of the conveyor belt, the back, or the end of a separately loaded conveyor belt. Belts and conveyor pulleys provide maximum grip when driving the belt. The head wheel is located at the discharge end of the conveyor, and the conveyor is usually a driving wheel. The rear conveyor pulley is located at the feed end of the conveyor. Conveyors and simple conveyors Generally, drum welded steel drums with solid hubs are introduced, and it is found that this is an improvement on the arm design. One advantage that was immediately realized was the closed design, with large endplates that prevent material from entering. It is not immediately recognized whether the strength or load-bearing capacity of this structure has increased. This design also allows greater flexibility in the thickness of the endplates and rims. design. They are cast in one piece, chiseled, drilled, bonded and tightened, bonded only, screw only or smooth hole, bronze bushing, solid hub, or clip type. The standard single pulley design provides an effective belt tension of 65 pounds per inch of face width; for multi-link pulleys, the effective belt tension is 120 psi and the surface width. In the event of a pulley problem, the maximum tension will be considered instead of the effective tension. The equations used to establish these classifications are based on the commitments made by members of the Mechanical Power Transmission Association committee during the development of this standard. Other pulley designs, such as ball-end pulleys, magnetic cages, and special self-cleaning structures are of high quality. Motor pulleys with non-rotatable deflection shafts are available, but these versions are not subject to the aforementioned pressure welded steel wheel standards. a Usually used to prevent materials from entering the belt and accumulating on the surface of the pulley. These pulleys may be straight or end-shaped, and usually have a plurality of flange plates that extend radially from the longitudinal axis of the hub and are evenly distributed around the circumference of the conveyor pulley.
