irreversibility reducer epicicloidal

[Merolla]

Bye to all,
I have to design an irreversible epicloidal reducer without the use of a car. Can you help me by telling me how I can achieve the irreversibility of the system? What parameters should I consider?
Thank you.

parallel gears are also known for non-irreversibility. So much so that to make an irreversible epicycloidal you mount an endless screw as a prepair.

In fact, I am required to use only epicycloidal reducer to obtain an irreversible system. ..no kind of endless screw reducer...can't it be something that fits with the geometry of the epicycloidal gearbox and the transmission ratio?

thanks for the answers.
in case I use a cycloidal reducer, to have irreversibility, what parameters should I consider?

You can't, it's not possible, as long as you're asked, you won't, enough, tell him that their request has no answer. :wink:

...saving the epicycloids, I actually read that cycloidal gearboxes have an irreversible mechanism. Can someone explain to me why this irreversibility or link documents in which this concept explains? Thank you.

unlike many other drive mechanisms the cycloidal drive is not typically backdrivable.
due to the eccentric nature of the drive, if the cycloidal disk is not balanced by a second disk or a counterweight, it will generate vibration which will propagate through the driven shafts. this will cause increased wear on the exterior teeth of the cycloidal disk, as well as component bearings.
