You should give it some thought :) But... The radial engine depicted in this video is a four stroke engine. This means that each cylinder fires once every two revolutions of the engine. Another observation is that each cylinder achieves TDC sequentially in a circle around the engine as it rotates. After TDC either combustion or intake stroke begins. For the vibration and even power stroke distribution it is desirable that every other cylinder begins a combustion (ie. it fires) and every other cylinder (those between former) starts an intake stroke as it rotates. The only way to achieve for all cylinders to fire in this configuration is to have an odd number of cylinders. Thus in the nine cylinder example above the firing order is: 1- skip 2 because it started intake stroke - 3 - skip 4 -5 - skip 6 - 7 - skip 8 - 9 - skip 1 (astute reader will observer we started a second revolution of the engine at this point) - 2 - skip 3 because it started its intake stroke - 4 - skip 5 - 6 - skip 7 - 8 - skip 9 and now after two full revolutions we are back at the configuration we started with. This is only possible with an odd number of cylinders. In example if we would have an 8 cylinder radial and a firing sequence would skip every other cylinder(desirable) only cylinders 1-3-5-7 would ever fire, because we would skip number 8 and landed back on 1. Theoretically there is another possible configuration where in the first revolution every cylinder fires, thus the first revolution is composed of combustion and exhaust stroke, and none of the cylinders fires on the second revolution because this second revolution is composed of intake and compression strokes. Such a radial engine would run very uneven, but it could have an even number of cylinders. Also, bear in mind, that every four-stroke piston engine returns to the same state every 720 degrees of rotation. And as a side note: inline engines are not limited to even number of cylinders. There were plenty of five cylinder inline engines. I think even 7 cylinder inline engines existed at some point. 3 cylinders inline engines are all the rage nowadays. And as a food for thought, a 5 cylinder V engine exists. :)
does the worm gear and the wheel gear attached to it move in the same direction? And also, if we were to have a straight bevel gear with two gears horizontally on it would they both move in the same direction?
I'd like to find out the course of a axis to make a small project using mechanical parts and this is hinting me something. Is there any software that one can experiment finding out gear course motion?
