提出了细粒齿辊破碎机在实际应用过程中主轴时有断裂的现象,分析了主轴断裂的主要原因,重点对主轴设计缺陷进行分析,分别对主轴直径的设计、主轴轴肩自由表面过渡圆角的选择以及主轴与轴承配合的设计深入探讨,总结了克服设计缺陷对主轴断裂的影响和实际推广的意义。
The main reason of spindle fracture is analyzed. The defects of spindle design are analyzed emphatically. The design of spindle diameter, the free surface transition circle of spindle shoulder The choice of angle and the design of the cooperation between the main shaft and the bearing are discussed in depth. The influences of overcoming design flaws on the fracture of the main shaft and the significance of actual promotion are summarized.
