所以主动轮的功率可以根据公式P=Fv
所以主动轮的功率为P=Fv=425×0.331=141w
(3) 主、从动轮参数的计算
本次设计的链传动为单排滚子链,链轮的结构形式为整体式钢制小链轮
主动轮分度圆直径d
"d=" "p" /"sin" 〖〖"180" 〗^"°" /"z" 〗
其中p=15.875 z=25,所以d=126.66mm
齿顶圆的直径da
"d" _"amax" "=d+1.25p-" "d" _"1"
"d" _"amin" "=d+(1-" "1.6" /"z" ")p-" "d" _"1"
其中p=15.875 d1=10.16 d=126.66,所以damax=136.34mm damin=131.36mm,选取da=134mm
齿根圆直径df
"d" _"f" "=d-" "d" _"1"
其中d1=10.16 d=126.66,所以df=116.5mm
分度圆弦齿高ha
"h" _"amax" "=0.625p-0.5" "d" _"1" "+" "0.8p" /"z"
"h" _"amin" "=0.5(p-" "d" _"1" ")"
其中d1=10.16 p=15.875 z=25,所以hamax=5.35mm hamin=2.86mm
