| 摘 要： | 600kt/aDAP装置回转干燥机传动系统故障停机占整个干燥机故障停机时间的80%.其中,鞍座底板断裂、鞍座连接螺栓和销轴断裂,通过断口形貌和受力分析,判断故障原因为典型的疲劳断裂;大小齿面磨损变形严重是齿轮硬度不足、齿面接触应力超过材料抗剪屈服极限及润滑方法不当造成.并提出改进对策.

| Abstract: | The 80% of total fault shutdown time results from the driving unit fault of rotary drum dryer in 600 kt/a DAP plant. The faults include the fracture of saddle support mat, the breakdowns of saddle support bolt and pin spindle. Based on the analysis on the fracture and surface, the fault causes are analyzed, for the conclusions of the normal fatigue fracture, as well as the deficient gear hardness, higher contact stress of tooth face than the yield limit under shear of material and improper lubrication method, which bring serious abrasion deformation of tooth face. Further some countermeasures are presented. [HJ] |
