2 圆周速度

本系列减速器的齿轮圆周速度均指齿轮相对于行星架的圆周速度,各级减速器的齿轮圆周速度见表7。

3 选用方法

3.1 选用NGW-LDF型行星减速器时,应根据下列计算选择:

PX=PS·K1·K2或TX=TS·K1·K2

式中:PX——选用输入功率KW

PS——实际输入功率KW

TX——选用输出扭矩N·m

TS——实际输出扭矩N·m

K1——使用系数,见表1

K2——与润滑有关的系数,当减速器采用油池润滑时,K2推荐值见表2。

根据计算出的PX或TX和其它已知条件,按表1~表6选用减速器,应满足PX≤P1或PX≤T1,T1为列表值。

3.2 减速器的最大尖峰负荷为许用负荷能力的2.5倍,当按上述方法所选减速器,其实际尖峰负荷超过许用值时,可按1/2.5的实际尖峰负荷即(Pmax/2.5、Tmax/2.5另选。

3.3 当高速轴的转速低于600r/min,按n1=600r/min的低速轴许用扭矩选用。
