行星減速機的選型計算公式
例:被驅(qū)動設備所需功率為3KW,轉(zhuǎn)速=360r/min,工作12小時/天。均勻負載啟動次數(shù)少,求電機型號!
答:(一) 電機選型
1、 假設選擇電動機的轉(zhuǎn)速為1450r/min,計算減速比
i=n1/n2=1450/360=4.028≈4
2、減速機的級數(shù)為一級(3-10)
3、減速機效率η為96%
4、均勻負載且在啟動次數(shù)少的情況下可選f1=1.25
5、電機功率為p1n
p1n≥p1 × f1=p2÷η×f1=3÷0.96×1.25=3.90625KW
6、根據(jù)轉(zhuǎn)速、功率確定電動機型號
(二) 減速機選型
1、計算被驅(qū)動設備的扭矩 T2
T2=9550×p1/n2=9550×3/360=79.58Nm
2、計算減速機輸出扭矩T2N
T2N≥T2×f1=79.58×1.25=99.475Nm
3、根據(jù)減速比、減速機輸出扭矩、輸入電機端尺寸、輸出設備端尺寸選擇合理的減速機。符合的減速機型號是 ZCF90-4-S2 (輸出扭矩為150、速比4、標準側(cè)隙)
