Default 行星减速机的选型

行星减速机的具有重量轻、体积小、传动比范围大、效率高、运转平稳、噪声低、适应性强等特点。正因为有以上这些特点, 使得行星减速机使用范围特别广,那么如何选择行星减速机又是一件不容易的事了。下面磊诺传动简单教您几个选型的办法:
1: 要确定需要的减速比。
2: 确定减速比后,请将您选用的伺服电机额定扭矩乘上减速比,得到的数值原则上要小于产品型录上提 供的相近减速机的额定输出扭矩,同时还要考虑其驱动电机的过载能力及实际中所需最大工作扭矩。所需最大工作扭矩要小于额定 输出扭矩的2倍。满足上面条件后请选择体积最小的减速机,体积小的减速机成本相对低一些。
3: 回程间隙。回程间隙越小其精度越高,成本也越高。用户要考虑横向/径向受力和平均寿命,横向/径向受力大的减速机在安装和使用中可靠性高,不易出问题。
4: 最后您还要考虑所配电机的重量,精密减速机。一种减速机只允许与小于一定重量的电机配套,电机太重,长时间运转会损坏减速机的输入法兰。
