CAT tax
Ahoyyhoyy

Almost all of these are dependant on lubrication after a short amount of time.

Dat cat tax though!

Never too late to change my major....

Upvoted for CAT tax.
DanceWithMeLampy
Mechanical engineer here. Could someone please bring me a change of pants?
UrsaUrsa
That's one sexy cat
StirlingMaloryArcher
Thats a lovely Wankle you have there
ViktorVolk
The fact that these gifs aren't loops make me uncomfortable
AncientPostNecromancer
#3 is overcomplicated, just put a bar between the center of each cog with 2 bushings. You have unnecessary wear the way it is.

Take my +1 for that CAT tax alone.

+1 for CAT tax

I might make some of these in 3d for my game... if anyone remembers me, i promise im still working on making that gif!!

My favorite is the wheelie thingamabob with the shiftybits going roundabout all the way
JAFIOI
Really? I preferred the spinny thing with the kajiggers on it.
Doopapotamus
I see that we're all trained engineers here, using proper terminology and whatnots. I like the one with the twisty gubbinz, myself.

FP edit: thanks everyone. I would love to add more of these to my collection so post what you got in the comments.

I own a real life version of #1. It's called a bull shit grinder.
SuspiciousCharacter
Slower you slut!
hadamardTransform
Thanks good sir. It's almost as if people forgot their good manners!
owlest
how do people figure theses complicated gears out
Ketheres
These are simple, start mixing them together for some real fun
doodybird
Certain kinds of brains are better at engineery things.

Maybe you should wankel?

I feel you. (But mostly I feel me)

#2 isn't the centre, crescent shaped piece kind of useless?
trexil
No, keeps it from moving until the pin is in place.
ChronologicalMyopia
It's needed, had a working model of some of these in my engineering class, it ensures that the cog is always in the correct alignment.
BrendanDufftronic
It's a guide.
theupvotenazi
Theoretically I think yes, but functionally I think it's necessary to ensure the cog piece doesn't wiggle out of place and mess up the pin.
therooter007
It holds the red wheel in place while the pin is not engaged. If something is attached to the red wheel it could cause it to move otherwise.
inconspicuouselephant
its only purpose it to allow the rotation of the red portion
doodybird
*prevent
inconspicuouselephant
symantics. It dtermines when to allow that portion to rotate.
doodybird
When it's engaged it only prevents motion. When it's not engaged it's irrelevant.
TheRenegadeSpud
Is #7 how Mazda's rotary engine works, or am I way off the mark here?
GeneralBullshit
Yes, got one in my 2004 rx8
casapalooza
You're correct. It's a Wankel.

Dead on the money, best engine never given enough R&D

My reaction to every one of these is "shit I should have thought of that"
digdoug78
Except you have to remember "socks, then shoes".
Bolensgoldrush
Explain pls
slypea
damn, this isn't my thing but show me injection moulding and i'll be injecting everywhere
Crumpus
Wouldn't #7 be inefficient because the ignition chamber's volume increases as it traverses?
therooter007
That's how it draws in the air/fuel mixture. Same action/principle as the first stroke on a 4-stroke piston engine.

Wankel / rotary engine
mineovermatter
"Inefficient"...depends on the measure.By weight produce a lot of power.But tend to consume more fuel than others of similar displacement
Crumpus
It's a very impressive little engine, I found out. For most of the applications that you want to use one it's very good.

I'm sexually attracted to cogs.

What a coincidence I sexually identify as a cog.

I wish there was a short description to tell what the practical application of each of these would be.

#2 is used when recording movies on film. With every turn it stops the tape on every frame, without it all you'd see is blur.

Last 4 are engines w/ automotive and aeronautical applications. #7/8 (wankel&H4)are used in certain cars and #9/10 (radial)used in planes.

#1 is also a carpentry jig used with a router to make ellipses

#7 is a wankle rotor, it is used in some Mazda sportscars. It's light and powerful, but has emissions problems so is rarely used otherwise.
GroundHOG2010
Other uses of the Wankle include aviation, and they have low fuel usage at low RPM, so make good generators! Also, jokes. Lots of jokes.
TheGreatAnhey
It makes me happy when I see the wankle for some reason
doodybird
Wankel rotory engines can be modded with extra rotors to boost horsepower. https://www.youtube.com/watch?v=RJnyJyBxzCE

#8 is not a H4 or a Boxer 4, but is more a 180 degree V4 engine, or a flat four. A boxer has the piston on each side move towards or...
GroundHOG2010
Away from the crankshaft at the same time, and each piston is offset. 180 V engines are rarely used, as they have no real advantages...
GroundHOG2010
Boxers, which are smoother that V engines, are used in light aircraft, motocycles and cars. Subaru usually uses them.

#9 and #10 are both 4 stroke radial engines. The firing order is every other cylinder on them, so #10 has the firing order 1, 3, 5, 2, 4...
GroundHOG2010
This is why all 4 stroke radials have an odd number of cylinders. Radials are used mostly on aircraft, with the 9 cylinder most likely seen
GroundHOG2010
on pre-WW2 era aircraft, while the 5 cylinder could also be seen on more modern light aviation. Advantages over inline engines include...
GroundHOG2010
being air cooled, but they cause more drag. They also seemed more reliable. They were also used, famously, on some american tanks during WW2
GroundHOG2010
Major uses - Airliners til the jet era, Japanese Military, American Navy, Bomber aircraft til the Jet era, and the FW-190.
GroundHOG2010
Some rare race cars also used them, along with early helicopters and autogyros.
GroundHOG2010
Correction, less parts and simpler systems (I.E, not having liquid cooling) made them better against battle damage and more reliable.
