Hello I want to ask that is it possible to have the number of teeth of sun gear and pinion will be same? As In my case the ratio is 4:1...outer ring is fixed and sun gear is the input. I want to use three planets. and if I take 14,16,17 for the sun gear then the condition of (Z1 +Z3)/number...

Thanks all for the replies. One more thing I want to ask is about the shaft. As I want to design a series planetary gearset. So how I calculate the torsion on shaft at diff stages. And one more thing about the series planetary gearset. How it works and different from others...

I don't have the details of oil rig... I only have the specs of motor and the requirements... can you please tell me how I calculate the torques and forces on the shaft to start it... waiting for the reply

there is not a constraint of 3 stages. may be 2 is ok. it's a lot easier now you don't have such high torques! Just make each stage's ratio the cube root of 4. I don't understand this... why cube root of 4...?

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...

Hello, Thanks for the reply. Can you kindly tell me about it in detail what should I do with forces, torque, gear ratios etc

Hello, I have to design a series planetary gear speed reducer. I have to ask first that what is SERIES planetary gear? Can anyone give some detail about this. I have to design a gearbox with three stages with a motor power of 45 KW. Input speed of Motor is 2800 rpm, Max outer dia of...
