Hi. I have a quick question about a differential made up of 4 bevel gears. Say there are two axles which go into either side of the differential as shown in the diagram. Both axles have a pin mounted at the end to track its position radially, initially both pins point up...

Hi! Thank you, it took me a while to find them. I am looking to get around 2000-3000rpm

Hi. I need some wisdom! Here is my problem. I want to make an air powered engine. This isn't a problem, I have plans for this. However, I want to put my own twist on the engine. I want it to be a axial engine, so the axle is in the same plane as the cylinders. The importance factor is...

Ah I see, that's quite interesting actually. Do you think a circular cam with a wave cut into its circumference and then attached to the cylinders via rollers would also be viable? It would mean I wouldn't have to use springs to push the pistons back down.

Hi, i know what engine it is, I am after the mechanism that converts the reciprocating motion into the rotational movement of the flywheel at the top. I don't think a crank and slider mechanism is what is used, since the reciprocation motion is on the y axis, and the rotation movement is...

Its worth noting that the reciprocating motion is the powered motion and the rotational movement is the output

Hi, I was just wondering what kind of mechanism is used in this video It converts the up and down movement into rotational movement, and it all seems very compact and smooth. James

Ok, I understand all of that. However what happens when the length of the pivoting connecting rod is different between piston A and piston B? Say piston A has a length of 10 cm and piston B has a length of 5cm?

Hi, Thank you for the reply. That makes sense, but when I consider the length of the shaft that it pivoted, I still am I bit confused. After thinking about this for a little bit, I think the best way I can explain it is the following: In my first image, will the travel of the cylinder head...

Hi, I have a question about one of the engines I am looking at for a project. I am linking two cylinders together. One is a cylinder with a pivoting shaft (piston A), the other piston has a cylinder with a fixed axle so it can only move in and out (piston B). To allow piston be to move with...

Hi, Im trying to work out the dimensions of the offset on a cam for a project. I know the travel of rod c, as well as the length of the connecting rod b, but I am not sure what the lenth of dimension a should be. I know this is probably simple maths (just pythagoras?) but I need to make sure...

Hi. Its a StirlingEngine. The offset between the crank pin and the centre axle is .625 inches (the travel of the piston is 1.25 inches) Hope the exert below from a website can clarify:

Im really stuck here, I asked my friend and he said this: Can I get a second opinion on this to make sure I don't do it wrong.

Just to also run this past you, when it says a 90 degree offset, I guess that is the same as saying 1/4 offset?
