I 3D Printed a Transmission: How Strong is it?

Рет қаралды 153,628

Жыл бұрын

Today, I 3d printed a 3 speed manual transmission. The transmission was made for my 3d printed air engines and other purposes. This specific type of transmission is what's known as a 'dogbox' since it does not use any synchro meshes but rather dog gears instead. The intention of the design is to allow one to shift the transmission while under load, unlike a typical transmission. Race cars are often equipped with this type of transmission as they can handle much more power.

I might be a bit late, but one substitute for the plastic bushing could be a yo-yo bearing. They're about half the size to a quarter of the size of a skateboard bearing. Not entirely sure if they can withstand a good compression as all they do is hold the string of a yo-yo. But could be worth giving a try to reduce wear and having to replace the plastic bushing as often. Awesome video though!

Maybe redesign the dog gears to have a 45° incline before a positive 90° lockup between gears. Maybe the friction between the gear and dog gear will allow for a smoother transition instead of a higher torque shock when shifting between gears. Provided, such friction in motor vehicle transmissions would wear down the components much faster, but for a 3D printed model, it might make it smoother without requiring synchros. How'd you make the shift forks and how do they mesh with the shifter?

You are loading the transmission with centrifugal force from the flywheel. Would of been nice to see how much torque it could output before it started to break apart. The being that the break was at the drill the test only showed that the immediate torque from the drill which can be extreme broke your input shaft.

I mainly use PETG for all my filaments, when you print parts that interact with another 3d printed part you generally want a tolerance of 0.5mm. If the part interacts with a machined part like a rod, you want 0.25mm of tolerance

that way of engaging gears really sucks. a differential can be used to engage gears using breaks. so the gears dont grind but thats why the clutch is used. my idea would pretty much use a different break for each gear and no clutch needed. just got to find a way to organize all the differentials in some compact way to make the breaks on the outside so there easily replaceable.
