Motion Analysis of Planetary Gear System

CALCULATION FOR THE PITCH CIRCLE DIAMETER OF THE PLANETARY GEAR

Radius of ring gear(Rr) =radius of sun gear(Rs) + diameter of planetary gear(Dp).

Rr=Rs+Dp

115/2=35/2+Dp

Dp=(115-35)/2

Dp=40

Pitch Circle Diameter of the planetary gear is 40mm

Pitch circle diameter (Dp)=Module(m)*No. of teeth(t)

Dp=m*t

t=Dp/m=16

No. of teeth of planetary gear =16
