日前普遍使用的C616车床,主传动系统工作时经常出现异常声响。这种现象与主电机轴键槽扭曲及键的损坏有关。经分析,认为问题在于JO系列电机先天不足,即该电机轴的直径φ25,且槽较浅,极易造成损坏,尤其是切削量较大或操作中正反急停时,负荷超限使轴扭曲或键槽损坏。由于该系列电机属淘汰产品,更给修复增加了困难。我们决定用Y系列电机替代。经查,Y100L_2-4-B_s-3kW电机的技术数据优于JO_2-3kW电机,且轴增至φ28,键槽加深1.5mm,替代可行。但在具体执行过程中发现Y系列电机与JO系列电机的安装尺寸不符,而且需要对变速箱体改造
Commonly used C616 lathe, the main drive system often abnormal noise. This phenomenon is related to the distortion of the main motor shaft keyway and the key damage. After analysis, the problem is that JO series motors are inherently deficient, that is, the motor shaft diameter φ25, and the groove is shallow, easily lead to damage, especially cutting large or positive and negative during operation, the load exceeds the limit so that the shaft twist Or the keyway is damaged. As the series of motor products are eliminated, but also to repair more difficult. We decided to replace the Y series motor. The investigation, Y100L_2-4-B_s-3kW motor technical data better than JO_2-3kW motor, and the shaft increased to φ28, keyway deepened 1.5mm, alternative feasible. However, in the specific implementation process found that Y series motors and JO series motor size does not match the installation, and the need to transform the gearbox
