偏心套是旋回破碎机系统中重要的零件之一,它承担着对原矿石进行粗破碎工作,在实际工况条件下,承受着极大的冲击力、剪切力及挤压力等交变应力的周期性作用。偏心套工件频繁的运转周期、复杂的受力状态及恶劣的工作环境决定偏心套工件必须具有较高的生产加工质量。近年来,国内外许多生产厂家,为提高偏心套工件的制作质量,延长其在实际 Eccentric sleeve is one of the important parts of the gyratory crusher system, which undertakes the rough crushing of the raw ore. Under actual working conditions, the eccentric sleeve is subject to great impact, shear force and squeezing pressure. The periodic effect of stress. Eccentric sets of parts frequent operation cycle, the complex state of force and poor working environment to determine the eccentric sets of parts must have a higher quality of production and processing. In recent years, many domestic and foreign manufacturers, in order to improve the production quality of eccentric sets of parts, to extend its actual
