pic: Versa Planetary Plate

[Paul Copioli]

I can assure you that these did not start this way.

I can tell from one of the holes that it has been elongated and the pins lost their press fit. This is one of the two main failure modes for overload on a 10:1 plate. In all planetary gearboxes the pins that the planets rotate about see the highest load by a factor of 2.

I seem to remember your post from another thread where you were using this 100:1 with a 775. Is this correct?

What is the rest of your loading condition?


The carrier plate is the weak spot in the 10:1 design and we will try to increase its strength, but remember this gearbox has about 2x the load rating of the next closest competitor in this gearbox size and no one has a single stage 10:1 reduction stage.
