Why pulley malfunction? Pulley pulley will cause of a failure in the course, due to the equipment used for too long or design errors and other causes of failure of the belt wheel. Years of practical experience to remind you that the reason pulley failure made the following summary: Since the pulley in the production process put through rigorous quality control, dimensional strength in line with long-term production. However, since it is considered improper handling can cause tooth this situation. Since a large number of teeth in the process of China-EU standard bearer pulley wholesale prices, root out the extent of bending strength is maximized. Followed by the root causes of tooth marks by section, and will focus efforts on the teeth, causing tooth broken pulley fatigue 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 and high-quality European standard pulley manufacturers, tractors, automobiles, mining machinery European standard pulley Which is good, machining equipment, textile machinery European standard pulley, packaging machinery, machine tools, forging bed, some small horsepower motorcycle power transmission, the transmission power of agricultural machinery, air compressors, reducers, gear, generator, ginning machines and more. European standard pulley Which is better _ Hengda Machinery (certified) _ Tianjin European standard pulley by Texas Hengda Machinery Co. Texas Hengda Machinery Co., Ltd.
