Hi.
I am trying to figure out how to couple two seperately driven shafts so that the speed of shaft B is always at X RPM greater than the speed of shaft A regardless of what speed A and B are driven at.
(X is a constant, but the value depends on some still unfinished math, we will say 500 for now.)
A--C--B
A is a variable speed (1000 - 7000 RPM) 500 HP motor.
B is a variable speed (2400 - 16800 RPM) 200 HP motor.
B is always spinning significantly faster (anywhere from 1400-9800 RPM faster) than A in the same direction.
C is the coupling device.
Regardless of how fast A is spinning, I want C to limit the speed of B's shaft to X RPM greater than the shaft of A.
Can this be accomplished with C being some type of a Fluid Coupling device?
This is the configuration I was thinking of...
(sorry for the poor diagram)
A--C--D--B
E-----|
A is connected to C with a direct shaft.
B is connected to a differential gear set (D) with output 1 connected to C and output 2 serving as a secondary power path (E).
I want output 1 of D to always rotate at RPM(A)+X.
For example:
(if X is 500)
If A is spinning at 2000 RPM and B is spinning at 4800 RPM:
I want output 1 of D to be spinning at 2500 RPM.
If A is increased to 3000 RPM and B is increased to 6000 RPM:
I want output 1 of D to be spinning at 3500 RPM.
C will be effectively acting as a speed limiter for B.
Is there some type of Fluid Coupling that would accomplish this?
If not, do you have any suggestions regarding what configuration I can use?
Thanks for any help you can offer.
