楼主，远离电机的两个同步升降器所需扭矩应该大于电机同轴的同步升降机。可以试试假设远端同步升降器所需扭 ...
余留当时设计的时候，留的很大，在2倍安全系数下*1.5倍，也符合要求，不过这个值比较接近负载率100%了。
安装和加工问题的可能性更大，1.5m*0.9m也不小哦，另外我看你的速度0.15m/s，也不是很快，导程可以选小一些，控制下间隙问题，还有就是仔细校核下惯量的问题，应该就没什么问题了 刘火火 发表于 2023-4-13 14:37

惯量算的应该没问题，减速机转动惯量（按同型号APEX），联轴器转动惯量，螺旋升降器（按减速机计算），传动轴，伺服电机，还额外加了4个负载滚珠丝杠，加减速，这个应该是还可以了。
安装的话，会有点，下面是铝型材，不过变形不至于差的太离谱，对扭矩有这么大影响。

不会，调试起来也简单，就是负载率，功率问题，实际比我大了一倍。建议这玩意不要弄国产的，底座刚度大点，我自己总结：问题出在底座刚度有问题，造成滚珠丝杆不垂直，就是不知道为什么实际比计算会差这么多。
我现在用的场合是上下料，24x7，每分钟2次的使用频率.
