This is a design that I made in OnShape for a simple planetary gear mechanism. The number of teeth in each component is:
Sun gear - 25 teeth
Planet gears - 25 teeth each
Ring - 75 teeth
The ratios for the components are as follows:
Sun to ring - 3:1
Planets + holder to ring: 3:4
Sun to planets + holder: 4:1
The gears are all exactly the same so here’s what you need to print, with rough times for how long each part took to print on my FLSUN QQ-S:
Gear × 4 - 1h 30m each, 6h total
Holder × 1 - 4h 37m
Barrel × 1 - 4h 25m
IMPORTANT: You must print each part separately otherwise your printer may not print the parts accurately enough to where they can fit together well.
While this is a free model, I benefit a lot from tips, whether that be money or advice for my models or printing. If you choose to tip me, my PayPal is accessible through the “Tip the designer” option :)
