SCWU、SCWS、SCWO轴装式减速机执行标准JB/T63
SCW轴装式圆柱蜗杆减速机的安装：
1．SCW减速器与工作机的安装为避免工作机主轴挠曲及在减速器蜗轮轴承上产生附加力，减速器与工作机之间的距离在不影响正常工作的条件下，应尽量小，其值为5～10mm。
2．安装时要求与SCW减速器相配合的工作机轴端应带有平键和螺纹中心孔，平键按GB1095-1979的规定，中心孔应按GB145-1985规定的C型。
3．SCW减速器沿工作机轴向定位采用轴端挡板和固定螺栓，轴端挡板与蜗轮轴固连在一起，以保证减速器轴向对中。
4．为便于减速器的拆卸，在SCW减速器安装前，须在工作机轴上与减速器蜗轮轴内孔退刀槽对应位置钻与拆卸孔垂直的排泄孔，以使铁锈溶剂通过安装在拆卸孔上的喷射器或泵打入油槽。采用的管接头必须与喷射器相适应。
轴装式圆弧圆柱蜗杆减速机使用与维护：
1安装位置
SCW减速器安装位置应考虑排油孔的油能顺利排出,且冷却空气循环流畅。
2联接
SCW减速器输入轴直接与原动机联接时,推荐采用弹性联轴器,联轴器不得用锤击装到轴上。
3与工作机的联接
SCW减速器直接套装在工作机主轴上,当减速器运转时,作用在减速器箱体上的反力矩,由安装在减速器箱体上的反力矩支架或其他方法来平衡。反力矩支架一端是与减速器直接相配,另一端与固定支承联接（见下图）。用户如采用反力矩支架来平衡反力矩,应根据设备安装要求同减速器一起向制造厂订货。
