Calculating Mass Moment of Inertia in a Two Stage Planetary Gearbox

[pachai34]

hi everyone,
help me, To calculate the mass moment of inertia at output shaft with respect to input shaft in the two stage planetary gearbox.

Torque at input = 15 Nm
input speed = 1440rpm
stage I
zs=14
zp=23
zR=61 fixed
stage II
zs=21
zp=40
zR=102 fixed

The mass moment of inertia, as I understand it, depends on things like the actual physical geometry of the gears. The information you have given is insufficient for such a calculation.

 

[pachai34]

can explain the method or formula for finding the mass moment of interia?

These calculations are covered in most dynamics courses.

It's not clear from the OP why you need to know the MOI.
