Jet Engine Component : Planetary Gear

thingiverse

I have created a cutaway model of several kinds of turboprop engines and Propfan engines. The basic component was simplified from size restrictions of my 3D printer. I then expanded each component to create the actual model which gives structure explanation. This time, it's the "Planetary Gear" model. Almost all Turboprop engines use "Planetary Gear" and some type of Propfan engine uses it too. Planetary Gear has three shafts. On turboprops, one input and one output are usually used. On Propfans, one input and two outputs are utilized. The following explainable elements were incorporated: (1) Three shafts can be turned and secured individually. (2) Combinations of shafts are shown in a photo, and all combinations will be established by this model. Download files include STL Files (16 items). STL file names start with "ws" to indicate "With Support," which is specially designed. Purchase Parts Information: Screws and Nuts; M2, M3 - See Photo. Assembly Points: Standard skills such as drilling, tapping, filing, tightening, painting, and gluing are needed, along with perseverance too. Assembly procedures are shown in photos. Fit checks between parts are essential. Using grease on plastic is very helpful to get smooth rotation. Total Net Print Time: Approximately 30 hours. (Estimated for PLA, 0.4mm nozzle, 0.2mm layer height, 40% infill, and no raft or support.) Note: When actually printing, each parameter may be adjusted according to your experience. 3D printing settings: Raft, Support, Layer Height, Infill - depending on your experience. My models were printed using "idbox" with a 0.4 nozzle and 1.75 PLA. I hope you enjoy making!
