How to disassemble the pulley? 1. Loosen all the bolts, remove one or two screws, oil lubricated bolt and bolt pattern according to the number of sophisticated knockout hole, insert the bolt holes as shown below disassembly. 2. Tighten the bolts alternately until the sleeve and pulleys release. 3. Remove the sleeve and pulleys from the shaft. Pulley belong hub parts, generally relatively large size, the manufacturing process generally casting, forging based. Generally larger size designed for casting methods, materials are generally cast iron (casting performance is better), rarely used steel (steel casting performance is poor); general smaller size, can be designed to forging material steel. Pulley indicators and the choice of materials is able to achieve the requirements under the premise of minimizing the raw material, technology is feasible, the principle of the lowest cost option! Pulley is mainly used for long-distance transmission of power situations, such as the output power of small diesel engines, agricultural vehicles Bushes, tractors, automobiles, mining machinery, machining equipment Bushes manufacturers, textile machinery, packaging machinery, machine tools, forging bed, Large Bushes drive some small power horsepower motorcycle, agricultural machinery power transmission spc Bushes, air compressors, reducers, gear, generator, ginning machines and more.
