Example Illustration

missing image of SGgearratio(f,nn,mm)

Syntax

[zzl,rat,ee]=SGgearratio([f,nn,mm])

Input Parameter

f: desired ration
nn: optional number of gear pair layers
mm: minimum and maximum number of teeth; default is [9 55]

Output Parameter

zzl: teeth sequence
rat: ratio
ee: relative error

Examples


SGgearratio(10)
SGgearratio(1/10)
SGgearratio(pi)
SGgearratio(355/113)
SGgearratio(exp(1))
[a,b,c]=SGgearratio(pi,4)
[a,b,c]=SGgearratio(60,4)
[a,b,c]=SGgearratio(60,3)
SGgearratio(40,3) % default number of allowed teeth
SGgearratio(40,3,[11 45]) % minimum number of teeth is 11
