Multiple transformations from rotational to linear force

[Black Mesa]

Hello all. I am working on a project and I am a bit stumped by something. Basically, I have 4 flat plates which can move vertically, independently from each other. I want to increase the force these plates exert upon another object. I am trying to figure out a way in which I can increase the force, by transforming a rotational motion into a linear force which will move the plates.

The tricky part is, can this be done sequentially, I.E. By turning one shaft can I first engage the first plate, and only after it is engaged, move the second plate an so on and so forth. The problem I've been having is once the first plate is at the full limit of its travel aka, the maximum applied force, the shaft to which everything is attached is going to lock up, and none of the other plates will be able to move. I've been trying to think of some sort of clutch mechanism, so that once the first plate is at its maximum force it "locks" into place and the clutch slips allowing the rest of the shaft to move.

Is there any common mechanical mechanism that would act as that sort of clutch? Is there another way to do this that I am not thinking of and/or should investigate? Thank you!

Hello, thank you for reaching out with your question. It sounds like you are working on a very interesting project. To increase the force exerted by the plates, you may want to consider using a gear system. By connecting the shaft to a gear, and then using smaller gears to connect to each plate, you can increase the force applied to each plate. This can also be done sequentially, as you mentioned, by engaging each gear one at a time.

As for the issue of the shaft locking up, you could consider using a ratchet mechanism. This would allow the first plate to reach its maximum force without locking up the entire system. A ratchet mechanism consists of a gear with teeth on one side and a pawl on the other side. The pawl allows the gear to turn in one direction, but not in the other, preventing the shaft from locking up.

Another option could be using a clutch mechanism, as you mentioned. A clutch allows for the disengagement of power between two rotating shafts, which could be useful in your situation. There are different types of clutches, such as friction clutches or centrifugal clutches, so you may want to explore which one would work best for your project.

I hope these suggestions help in finding a solution for your project. If you need further assistance, please don't hesitate to reach out. Best of luck!
