　　交流直线伺服电机直接驱动进给技术已趋成熟。数控机床的进给驱动有‘旋转伺服电机精密高速滚珠丝杠’和‘直线电机直接驱动’两种类型。传统的滚珠丝杠工艺成熟加工精度较高，实现高速化的成本相对较低，所以目前应用广泛。使用滚，珠丝杠驱动的高速加工机床移动速度90m/min，加速度1.5g。但滚珠丝杠是机械传动，机械元件间存在弹性变形、摩擦和反向间隙，相应会造成运动滞后和非线性误差，所以再进一步提高滚珠丝杠副移动速度和加速度比较难了。90年代以来，高速高精的大型加工机床中，应用直线电机直接驱动进给驱动方式。它比滚珠丝杠驱动具有刚度更高、速度范围更宽、加速特性更好、运动惯量更小、动态响应性能更佳，运行更平稳、位置精度更高等优点。且直线电机直接驱动，不需中间机械传动，减小了机械磨损与传动误差，减少了维护工作。直线电机直接驱动与滚珠丝杠传动相比，其速度提高30倍，加速度提高10倍，达10g，刚度提高7倍，响应频率达100Hz，还有较大的发展余地。当前，在高速高精加工机床领域中，两种驱动方式还会并存相当长一段时间，但从发展趋势来看，直线电机驱动所占的比重会愈来愈大。种种迹象表明，直线电机驱动在高速高精加工机床上的应用已进入加速增长期。

减速机的耐受度和清理工作怎么弄？
　 1、减速器壳体轴承箱磨损2、采煤机减速机箱体内孔轴承室磨损修复（二）减速机齿轮轴轴径磨损（键槽损伤）减速机齿轮轴轴径磨损（键槽损伤）减速机齿轮轴轴径磨损（键槽损伤）减速机在长期运行过程中，轴头经常出现磨损、键槽损伤，问题发生后，传统方法难以现场解决，必须依靠外协修复；而且都是用金属修复金属，无法改变“硬对硬”的配合关系，在各种力的综合作用下，仍会造成再次磨损。
　　运转应平稳，无冲击、振动、杂音及渗漏油现象，发现异常应及时排除。
　　安装就位后，应按次序检查安装位置的准确性，各紧固件压紧的可靠性，安装后应能灵活转动。
　　·油量应与安装位置一致。
　　·打开油位螺塞、通气器和放油螺塞。
　　油的更换冷却后油的粘度增大放油困难，减速机应在运行温度下换油。
　　·在放油螺塞下面放一个接油盘。
　　·拧紧油位螺塞及通气器。
　　当传动联接件有突出物或采用齿轮、链轮传动时，应考虑加装防护装置，输出轴上承受较大的径向载荷时，应选用加强型。
