简要说明行星差动减速箱的重要性及对其日常检测的必要性;通过故障个例,介绍了采用不同检测手段跟踪检测故障、并根据检测情况判别故障的位置及类型的过程。在修复故障设备过程中采用了新材料,这一方法值得借鉴。 The importance of planetary differential gearboxes and the necessity of daily differential detection are briefly described. According to the fault cases, the process of tracking and detecting faults by different detection methods is introduced and the position and type of fault are identified according to the detected conditions. The use of new materials in the repair of defective equipment is worth learning from.
