the overall ratio is 4 and the output speed is 700 rpm. but I have to divide it in 3 stages because of the torque is so high for 100 mm outer dia. the gear ratio will not change in three stages it will be same in 1st,2nd and 3rd stage. I think this can be achieve by using pinion and gears of same sizes in all three stages. so that the speed is not reduce in between the stages. but the forces are divided.
