Product Description CHINA LEADING FACTORY OF BELT CONVEYOR CONVEYOR PULLEY WORKSHOP SHOW CONVEYOR PULLEY - BRIEF INTRODUCTIONOur company has adopted proprietary technology and equipment imported from German PWH company for the design and manufacturing of various pulleys . As a key component of the belt conveyor, the pulley should have high reliability. Our company's R&D center has improved the pulley structure, reduced structural stress, and increased the lifespan and reliability of the pulley group through finite element analysis and optimization calculations. Our company's pulley is manufactured from specialized high-end manufacturing equipment and has achieved serialized and large-scale production.We have produced conveyor pulleys for belt width up to 2.4 m, pulley diameter up to 1.8 m, and maximum tension up to 300 tons.CONVEYOR PULLEY - PRODUCT INFORMATION Product Name conveyor pulley / conveyor drumCarrying Capacitylight, medium or heavy-duty typeSurface Typesmooth, rubber lagging, or ceramic rubber laggingAdehensive Treatmentcoal bonding or hot vulcanizationConnection Modefor the medium and heavy-duty pulleys, the shafts and wheels are connected by expansion sleevesPulley Pipe MaterialQ235B carbon steel, with high roundness and straightness ensuring rotation balancePulley Pipe Structurefully welded, cast welded, or built-in bearingsPulley PipeAdhesive layerordinary wear resistance rubber ( herringbone or diamond shaped, flame retardant);polyurethane coating (flame retardant) ;ceramic rubber coating;and other types as per requiredShaft 45 # round steel or according to your requirements;ultrasonic inspection, quenching and tempering treatment, strict control of key fit size tolerances, greatly extending service life.Bearing BrandsHavalo, SKF, FAG, SNK or according to your requirementsBear Seat Integral bearing seat or partial bearing seatColor customizedCONVEYOR PULLEY - MAIN TYPES CONVEYOR PULLEY - BEARING SEAT TYPES CONVEYOR PULLEY - TECHNICAL SPECIFICATIONS Technical Parameters for Belt Conveyor PulleyBelt Width (mm)Pulley Standard Diameter without Adhesive Layer(mm) 650 200,250,320,400,500,630800 200,250,320,400,500,630,800,1000,12501000 250,320,400,500,630,800,1000,1250,1400,16001200 250,320,400,500,630,800,1000,1250,1400,16001400 320,400,500,630,800,1000,1250,1400,16001600 400,500,630,800,1000,1250,1400,16001800 250,400,500,630,800,1000,1250,1400,16002000 400,500,630,800,1000,1250,1400,1600 Technical Parameters1Outer Circle Diameter D Deviation 200 ≤ 1.5 400 ≤ 2.0 1000 ≤ 2.52Radial Runout of Outer Circle D ≤ 200 ; without adhesive 0.3 ;with adhesive 0.5 200 < D ≤ 800 ; without adhesive 0.6; with adhesive 1.1 800 < D ≤ 1600 ; without adhesive 1.0; with adhesive 1.5 1600 < D ≤ 1800 ; without adhesive 1.5; with adhesive 2.03Static Balance Accuracy G40 CONVEYOR PULLEY - PROCESS FLOW Our company is equipped with necessary equipment for processing pulleys, such as large oil pressure machines, rolling machines, specialized pulley automatic explosive welding operators, large diameter lathes, boring machines, ultrasonic flaw detectors, static balancing devices, pressure casting machines, etc. Due to the special correction process adopted by the company, the pulley pipe skin is rounded before processing, and the pulley pipe wall is uniform after processing, thereby ensuring that the pulley has high static balance performance and high mechanical performance.CONVEYOR PULLEY - PRODUCT FEATURESFor pulleys with complex forces, large loads and used in heavy working conditions, they all adopt a cast welded structure and expansion sleeve connection. Compared with traditional drums in China, this type of drum mainly has the following characteristics :(1) The structural parameters of the pulley are advanced and reasonable, and there is a dedicated computer calculation program to determine the shaft diameter, cylinder skin thickness, wheel amplitude plate shape and spacing, as well as the position of the circumferential weld seam set at the position where the stress is minimum and the number of cycles is minimum.(2) The key technology of using single sided welding and double sided forming ensures the quality of the weld seam.(3) The expansion sleeve connection is used between the drum hub and shaft, which not only solves the problem of key connection stress concentration that has been existing for many years and the technical difficulties of manufacturing and installing axial double keyways, but also achieves overall quenching and eliminates welding internal stress.(4) The circumferential and longitudinal welds of the pulley have undergone non-destructive testing, and the casting quality of the wheel hub has undergone magnetic particle or ultrasonic testing.(5) The total radial runout of the outer circle after roller casting is less than 1mm.(6) All drums undergo static balance tests before leaving the factory to achieve G40 accuracy.(7) All driving pulley and directional pulley with high stress have undergone finite element analysis to ensure that the stress and strain of the rollers meet the requirements.Due to a series of measures taken, the pulley group produced by SK has a reasonable structure, large bearing capacity, and reliable performance. And it overcomes the problem of fatigue fracture at the welding seam of the existing pulley plate in China. The pullley (including the welding part) is guaranteed to have a rotational fatigue strength of over 108°.
