On belt conveyors, conveyor pulleys have three main purposes: 1) help the belt change direction on the conveyor, 2) transfer driving force to the belt, and 3) guide or form a group. The conveyor belt can be at the head or exit of the conveyor belt or the back or end of a separately loaded conveyor belt. Conveyor pulleys and conveyor are usually a driving wheel. The rear conveyor roller is located at the feed end of the conveyor. Simple conveyors and conveyors. Welded steel drums with solid wheels are widely used, which is seen as an improvement to the boom design. One advantage immediately became apparent, namely the closed design with a large endplate to prevent material from entering. It is immediately recognized whether the strength or load-bearing capacity of this structure has increased. The design also allows greater flexibility in the thickness of the endplates and rims. They are cast, drilled, drilled, glued, and fastened as a whole, just glued, screwed, or just smooth holes, bronze bushes, solid bushes, or clamps. The standard single pulley design provides an effective belt tension of 65 lb-in of surface width; for multi-link pulleys, the effective belt tension is 120 psi and the surface width is 120 psi. If there is a problem with the pulley, 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 transmission, magnetic separator, and special self-cleaning design, are of high quality. .... Motor pulleys with non-rotatable deflection shafts are available, but these versions are not available to meet the above-mentioned standards for pressure welding steel wheels. 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 extending radially from the longitudinal axis of the hub and evenly spaced around the circumference of the conveyor pulley.
