Huge Planetary gear - großes Planetengetriebe - in one print

myminifactory

Hello Factorians, Another toy to play with here. Aren't planetary gears beautiful? The magic of moving parts is quite captivating, and you can hold one part or another and watch it change operation. ATTENTION: This GEAR is 182.5mm in diameter and 29mm tall! It's definitely not a small item for your pocket. This one is perfect for seeing what's going on. Use Case: You can use planetary gears to greatly reduce the speed of a motor or any other device without building massive blocks for the bearings. You won't leave the axle of the original input, and if you hold the big wheel around the gear, you'll get slow speed as a result. This isn't the Original One: Why? (Original is the yellow/black on the pictures) The original design had lower tolerances, which is why I couldn't print it in one piece. I had to cut the outer ring once, build the gear, and then reattach the ring. The gear does a great job, and if you're interested, I can upload the files too! For the Original One, I also designed a motor mount (for my motor but not hard to modify it for your use case) + the outgoing parts from the 3 planet gears to an axle. If you prefer the original gear, just write in the comments. This One: This one has wider tolerances and is printable in one piece! The 2x20° angle on the gears prevents the planetary gear from self-destruction. It centers itself while turning. The result of the wider tolerances is more air between the parts and more movement. It moves great but is more to show how the gear works than to use it as a real gear. If you want a powerful, strong planetary gear, then ask for the "original" one, but you have to cut the outer ring once and glue it again. Look at the pictures to see the first layers printed on one of my deltas. The size is slightly less than 183mm in diameter, so you can print it on most printers with a Cartesian 200x200 or bigger + also the deltas with 200mm diameter or more! I made two of them with the same gears, but only one has centered holes in the gears to mount it to a motor. Use it as a gear with adapters, etc. Your choice, but I recommend the one with the holes. You're more flexible and use less filament. Plus, for future projects, you can also design your own input or output if you're interested, or I can design parts for motors and axes from the gears and so on. Just tell me what you need in the comment section. Have fun with the gear and please post your makes and videos while you're playing or using the gear. Many thanks and see you!
