Epicyclic Gearbox

Epicyclic Gearbox

(OP)
I am interested in epicyclic gearboxes to solve a design problem I have. Does anyone know if this type of gearbox design can achieve a 40:1 speed reduction. I am also constrained by size so this gearbox needs to be compact. Examples I have seen have low ratios and I fear the reduction I am looking for will require large gears that will not fit the space available to me.

RE: Epicyclic Gearbox

Yes they can.  Staubli makes their own epicyclic gearboxes and uses them on their robots, is a derivative of their textile technology I believe.  Their ratios are in that range.  There is a Japanese manufacturer that makes something very similar for the US industrial market, but for the life of me I cannot recall their name.

Compact?  That all depends on the load carrying capacity required by the application.

RE: Epicyclic Gearbox

Using conventional off the shelf planetary gear reducers, you would have to do a 40:1 reduction in two stages. But, this is not a problem.
