Spur Differential

[darrell_gray]

Hi,

I'm investigating designing a spur differential for small drive system with 4 parallel output shafts. Most designs that I am finding (schaeffler for example) involve applying torque to the planet carrier, which through the engagement of planets applies torque to each of the two sun gears and thus to each output.

In my scenario I have found it possibly simpler to apply input torque to one of the sun gears and allow the planet carrier to turn freely. Is there something fundamentally wrong with this?

Thanks,

No, torque and power input is not relevant unless one needs to minimize power loss through each gear set.

You can model the gear train using this applications:

I used that tool to design a gear train for my gate opener.
