行星减速机的选型计算公式

例：被驱动设备所需功率为3KW，转速=360r/min，工作12小时/天。均匀负载启动次数少，求电机型号！

答：(一) 电机选型

1、 假设选择电动机的转速为1450r/min，计算减速比

i=n1/n2=1450/360=4.028≈4

2、减速机的级数为一级(3-10)

3、减速机效率η为96%

4、均匀负载且在启动次数少的情况下可选f1=1.25

5、电机功率为p1n

p1n≥p1 × f1=p2÷η×f1=3÷0.96×1.25=3.90625KW

6、根据转速、功率确定电动机型号

(二) 减速机选型

1、计算被驱动设备的扭矩 T2

T2=9550×p1/n2=9550×3/360=79.58Nm

2、计算减速机输出扭矩T2N

T2N≥T2×f1=79.58×1.25=99.475Nm

3、根据减速比、减速机输出扭矩、输入电机端尺寸、输出设备端尺寸选择合理的减速机。

任何产品的生产都是有一定的成本的，而这种成本也正是决定产品价格的实际原因，正所谓一分钱一分货，当然阀门产品也不能例外。知名企业的阀门产品在生产过程中，从原材料的选择到生产工序等多方面都有着非常严格的控制，而这也正是保证阀门质量的基础。而正因为如此，也会使阀门产品的成本有所提高，因此价格过低的阀门产品也恰恰会暴露它低质的原形。总之，在对阀门产品市场进行详细了解后，选择适合自己的购买渠道，一定会选择到适合自己的阀门产品的。
