Bearing burnt-out fault of a ball mill happened frequently, which threatened boiler's safe and economic operation. 球磨机主要应用于发电、水泥生产等行业,球磨机烧大瓦事故时有发生,曾一度威胁着锅炉的安全经济运行。
Geometric, kinetic, and lifetime analysis of anti rotation mechanism with thrust ball bearing is conducted, which is commonly employed in the scroll compressor of automotive air conditioning system, and its wear during later stage's operation is also analysed quantitatively. 针对汽车空调涡旋压缩机中最常见的防自转机构滚珠防自转止推轴承,进行了几何、受力及寿命分析,并对其后期磨损加以定性的理论分析。
The characteristic of ball's axis vibration frequency spectrum is analyzed and a method to identify the load of coal depending on characteristic frequency is presented. The operation results are offered. 分析了球磨机轴振频谱的特性,提出特征谱识别载煤量的方法,并给出了实施效果。
