减速机技术资料：

减速机的主要产品类型和特点
减速机是一种由封闭在刚性壳体内的齿轮传动、蜗杆蜗轮传动或齿轮—蜗杆传动所组成的独立部件。 其主要类型：齿轮减速机；蜗杆减速机；齿轮—蜗杆减速机；行星齿轮减速机。 
一、圆柱齿轮减速机
单级、二级、二级以上二级。布置形式：展开式、分流式、同轴式。
二、圆锥齿轮减速机
用于输入轴和输出轴位置成相交的场合。
三、蜗轮蜗杆减速机
主要用于传动比i>10的场合，传动比较大时结构紧凑。其缺点是效率低。目前广泛应用阿基米德蜗杆减速机。
四、齿轮—蜗杆减速机
若齿轮传动在高速级，则结构紧凑；
若蜗杆传动在高速级，则效率较高。
五、行星齿轮减速机
传动效率高，传动比范围广，传动功率12W~50000KW，体积和重量小。
六、装式减速机
七、组装式减速机
八、多安装式减速机
九、联体式减速机
传动比分配
传动比分配的基本原则：
1 使各级传动的承载能力近于相等；
2 使各级传动的大齿轮浸入油中的深度大致相近；
3 使减速机获得最小的外形尺寸或重量等。
减速机润滑
一、传动的润滑
圆周速度v￡12m/s~15m/s的齿轮减速机广泛采用油池润滑，自然冷却。为减少齿轮运动阻力和油升温，浸入油中的齿轮深度以1~2个齿高为宜。
在多级减速机中应尽量使各级传动浸入油中深度近于相等。
为免太浅时激起沉降在箱底的油泥，应保持齿顶圆距离箱底不低于30mm~50mm左右。
若减速机的工作平衡温度超过90°C时，需采用循环油润滑，或其它冷却措施。
蜗杆圆周速度在10m/s以下的可采用油池润滑。蜗杆在下时，油面高度应低于蜗杆螺纹根部，并且不超过蜗杆轴的轴承的最低滚动体中心，以免增加功率损失。蜗杆圆周速度在10m/s以上的应采用喷油润滑。
二、轴承的润滑
轴承的润滑方法可根据齿轮或蜗杆的圆周速度来选择：
1圆周速度在2m/s~3m/s以上时----飞溅润滑
2圆周速度在2m/s~3m/s以下时----刮油润滑
3转速很高的轴承----压力喷油润滑
