分析了锥破碎机圆锥躯体与竖轴上的螺纹、锥面及球面磨损和竖轴裂纹的原因,通过具体分析和论证,提出了技术上可行、经济上合理、安全可靠且实用的修理方法。投运结果证明,修复后的圆锥躯体与竖轴可以满足设备安全运行的需要,不仅延长了圆锥躯体与竖轴的使用寿命,而且降低了设备维修成本,是一项对圆锥躯体与竖轴修理的成功经验。 The reason of thread, conical surface, spherical surface wear and vertical axis crack on conical body and vertical axis of cone crusher is analyzed. Through the concrete analysis and demonstration, a technically feasible, economically reasonable, safe, reliable and practical method of repair is proposed. The commissioning results show that the repaired conical body and vertical shaft can meet the needs of safe operation of the equipment, which not only prolongs the service life of the conical body and the vertical shaft, but also reduces the cost of equipment maintenance. It is a method of repairing the conical body and the vertical shaft The successful experience.
