安装减速器的混凝土基础或金属底板有足够的刚性；地脚螺栓埋人有足够的深度，采用垫片调平时，垫片厚度不应小于1mm;以保证负载运转时稳固，不变形。

找水平，与动力机、工作机对中，应分别进行。

水平仪精度要求一般为0.02~0.05mm/m，水平仪里于机体水平面的延伸外突表面或与水平面相平行的加工表面。对中的精度越高越好，要考虑所采用的联轴器对中误差的补偿能力，允差的大小，一般轴线交角误差不应大于10”，平移误差不大于0.1mm。

轴伸上的防锈剂、防腐剂清洗干净才能安装轴伸上的联轴器、链轮等零部件。清除防锈剂、防腐剂不应用砂纸、锉刀、刮刀等易伤轴配合表面的工具。装联轴器、链轮等不应用重锤打击，应采用热胀冷缩套装的方法。

轴伸上的链轮、带轮传动时所产生的压轴力好是指向安装基础。

与动力机的连接若采用液力偶合器。由于液力偶合器的质量较大，且启动时有较大的离心力，应避免液力偶合器的重力，离心力全部作用在减速器轴伸上，即液力偶合器不应悬挂在减速器轴伸上，而应与动力机共同支承。这样轴伸的支承点不产生附加弯曲。

减速步进电机与普通减速电机相比较，减速步进电机可以实现速度和位置的控制，普通减速电机则无法实现定位控制。
