Except if a pen were attached to the end of the lever where I would expect one would turn it, it could draw some sort of oval.

NOW IT FUCKING MAKESE SENSE
BLESS THIS THREAD
>>587906637
I second this
are there any free programs that simulate these?
>>587914529
It stops the red thing from continuing on spinning and jamming the device, it keeps it in perfect place for the pin to be received so it will never jam
So no, its essential
>>587914348
I mean with the engine actually running. I'm not if that's possible without transparent metal though
sprinkler gear
>>587912717
elipse.
>>587910640
i have a feeling the vibration created would negate alot of potential here. mostly because you need to waste a whole motion to bring each piston's crank arm back up the path on the output until you get back to the rounded part which is your power stroke. better thinking is required.
>>587906915

>>587914529
no it's stabilizes the other part

what is this
>>587908269
PHYSICS MUTHAFUCKA!
>>587906691
I love how all that leg movement is just caused by 2 rotating axes. I've seen one of those massive beach spider sculptures and they look amazing
>>587906037
Godbless this gif
>>587910640
Both strokes are power strokes, the only reason the shape is different when crank goes up or down is because of push/pull balancing of forces..., also the pistons counteract each others momentum keeping the device relatively vibration free, this si why 3 are used and not 2 or 4
>>587905363
FUCK THE GENEVA CROSS!
Those things agitate the shit out of me. They are fucking loud, very inefficient, and wear out way too fast. One of the worst things made.
>>587915761
it's simple but it makes you feel cerebral
>>587915198
>>587915021
im sure what your saying makes sense to a smarter person than myself
>>587915079
.....the term der comes to mind good anon. i appologize for my ignorance but pity you for your arrogance.
>>587915090
this doesnt make any snesne
>>587915392
it's a piston engine; your car has 2-4 of these working together like in >>587905427
>>587915200
and dubz
>>587916215
is the internal one more or less efficient?>>587905942
>>587915984
the pull mayhaps. idk m8
>>587916457
If the green half-moon wasn't there, the red part would keep spinning and mess up the whole thing
>>587916877
and dubz
>>587916631
...2-4?
>>587916612
how so?
>>587911548
Dat mechanical loss of energy doe
>>587916674
And singles
>>587916935
so theres just enough friction between the two to stop it when the green post exits the red part?
im so fucking hard right now
weirdest bonerrr
anyone got the gif of those blue balls going through loads of different processes sort of like a factory line?
>>587905942
Doesn't matter. It's doing the exact same motion either way.
You see as the disk rotates it is dragging itself across the inner wall causing vibration, loud noise, and wear and tear. All those combined just drives efficiency down.
This mechanism given is great to show to kids but highly unnecessary. At high cycles (faster speeds) this thing will tear itself apart.
Sorry. This mechanism has been driven into my head to just hate. Still an undergraduate engineering student though.

Ubderrated post
>>587916612
I'll explain the best I can from what I can see.
The outer partial gear, the sun gear, is the gear that controls the ejection of the water from the sprinkler. The inner partial gear returns the bottom gear to its original position so it can re-eject the water as the sun gear passes through again to repeat the cycle.
This is a very clever design none the less.
>>587918244
Link didnt work on my phone but thanks
>>587918256
Much appreciated anon, theres so much to look at
>>587908010
i have no clue what this is, but ive seen it countless times
someone care to explain?
>>587918274
My sides.
>>587916457
This should be self-explanatory.
>>587919312
What is there to understand? it is a mechanism that turns a gear in the opposite direction as its input
>>587908979
what's the advantage of this design?
>>587919263
here's the link
>>587920127
It doesn't have to convert reciprocating motion to rotary motion, making it more efficient and smoother. Intake, compression, combustion and exhaust phases overlap so you get more power for the same engine displacement than a four-stroke piston engine. On the other hand, there's a lot of friction and wear on the seals leading to high maintenance, and loss of efficiency when the seals are worn.
I see shits like that when i'm baked
>>587920127
High power to displacement ratio, and less moving parts than a piston engine.
>>587908722
You are literally too stupid to know that you are stupid.
>>587918256
I could stare at this for hours
>>587921826
i can stare at ur mum for hours
>>587921279
oh my GOD
>>587920844
Ooh, is this how a sewing machine works? sweet
>>587917100
some cars have two, some cars have four
>>587921279
what does this do?
>>587921988
i cud stair at yoo starin at is mum 4 hrs
Gonna contribute in this thread with one very nice video of how a differential gear works.
The video may be old but goddamn did it help me understand this design and apply it in building an RC car for my Machine Elements course.

>>587922141
Sewing machines are fucking awesome. My mum got a new one when I was about five, so I got the old one that had been playing up. I took it apart, cleaned out the gunk that was fouling the mechanisms, and learned to use it. In the end, the bakelite foot controller cracked exposing live parts so I had to get rid of it. In my 30s now, TFW my wife can't actually use a sewing machine but I can.

45 degree rotation transferred to 90 degrees.
>>587918656
I-is this real?
>>587922393
http://en.wikipedia.org/wiki/Constant-velocity_joint#Rzeppa_joints
>>587922949
no idea, but it's fucking amazing
>>587922393
It's called a constant velocity joint, or CV joint. The shafts are at different angles but the speed ratio is constant. Used in front-wheel drive cars to get power to wheels that need to turn for steering. Wikipedia has more detail.
>>587920127
making money for mazda
non-circular planetary gears.
>>587922393
turns horizontal rotation to any angled rotation. Think CV joint on a car
>>587923283
I've never driven a mazda, do rotary engines sound different?
>>587921580
I want that fucking table.

I love this thread. I love you guys.
>>587921769
actually the animal was dead and he bound the head with a little string to something
>>587924440
oops fixed:
>>587923613
Yeah, rotaries sound different. Most Mazdas have conventional engines anyway. It's just things like the RX8, RX8, RX3, R100, Luce, Cosmo and Roadpacer with rotaries. They gave good acceleration and decent power, but they were never efficient and always had high maintenance.
This thread is almost as cool as the tank threads
>>587924593
pretty sure that was just sped up
>>587918758
Converts simple rotation to a walking motion. Here's an example:
>>587923512
Sad part about these guys is that it requires a lot more torque than normal planetary gear system.
Also, if I remember when I played around with one it wasn't that backdriveable.
>>587924593
Nah, I used to raise chickens and they do seem to have some kinda internal gyroscope that helps keep their heads in the same position. Owls have the same thing.

is this how actually the pendulum work in old clocks?

Yep, that's pretty much how a clock escapement works.

Enlighten me.

sin cosin and tangent are the lengths of sides on a triangle
>>587928439
And that matters to this picture, how?
This is an impressive thread!
>>587928439
*sigh* it's the relationship between the ratios of side lengths and the angle of a corner of a triangle

No 7-Bag system, it's shit. At least it's only 9 Grid wide, so doesn't have to explain lack of line clearing.
