I'm having a bit of difficulty figuring out the theoretical efficiency of a compound epicyclic gear train. The math involved is a bit over my head. This train is meant to run at very slow speed under light load. I want to find the theoretical efficiency of the design so I can determine if it is...
I've searched high and low and can't seem to find the formula for an epicyclic gear train where the carrier arm is the input, the ring is the output and there is no sun gear. Any ideas?
Hello,
I'm designing a planet gear with an output of 4:1. Here are the details; Sun = 24 teeth, Planet = 24 teeth, Ring = 72 teeth. The sun is the input, planet carrier is the output. My question is what is the formula for finding the output of the planets gears themselves? For example, for...
