2 speed planetary gearbox 3d models

This 40mm x 34mm planetary gearbox fits a NEMA 17 motor and has a 4.444:1 ratio (9:40 decimal-averse folk will love). Version 2 features an M8 bolt output by default, with no need to reprint the whole assembly for size changes - just print the top...

This is a small simple planetary gearbox for a nema 17! This is designed to be as small and simple as possible due to this the ratio is only 4.2:1 but for a lot of robotics projects ( like mine, check it out on my website rpmengeerings.com!) its...

After this you can start to assemble this model. Align holder to stepper motor and decide how do you want planetary gears to be placed.Then glue backplate to the holder. Put internal gear in place (the big one).Place planetary gears and...

... durability, I've adapted an improved design capturing all four planets. While the pump function needs further refinement, the hand-cranked gearbox could be beneficial to others. ...I repurposed a Moineau pump hand crank, as it was readily available.

This is an emergency planetary gearbox (not mine). See original page for details. When you inevitably fail to print the little bolts and/or they break really easily, try BoltModified.stl. It'll print a threaded rod on its side, making it much...

Featuring a planetary gearbox, this motor has been my go-to choice for building battle bots. Its performance is exceptional and it's highly recommended. ...For real-life demonstrations, check out these videos:...

There were errors in the cover and base that slipped in at the last minute - I've corrected them, and posted those parts as their own files.I've tested this extruder over 2 days of fairly continuous printing with little sign of wear.OpenSCAD sources...

A Pusheen with a planetary gearbox inside, perfect for a unique Christmas gift. Made on a Makerbot Replicator 2X using grey ABS, your settings may differ depending on the machine and materials used. Print Details: (1) Ring Gear (1) Gear Carrier (1)...

This planetary gearbox is designed to be placed between a NEMA 17 extruder motor and its mechanism, allowing the use of an existing Airtripper or similar extruder and MK7 drive gear with a 5mm bore while preventing motor overheating. The design is...

Two-speed gearbox

A planetary (epicyclic) transmission system consists normally of a centrally pivoted sun gear, a ring gear and several planet gears which rotate between these. The advantage of a planetary transmission is determined by load distribution over multiple...

3 planets self centering planetary gear box 4:1 ratio. I recommend printing the planets in PETG while everything else in PLA so the planets don't stick to the casing if they get hot while running fast. ...

All of my planetary sets are interchangeable and rely on a 0.500 inch or 12 mm hex as the input and output shaft, making it easy to stack them and create different combinations. Each .stl file includes a sun gear, ring gear, five planet gears, a...

On the first stage of the gearbox, there are sun gears with 18 teeth, triple-satellite gears with 36 teeth, and a ring gear with 96 teeth. The second stage consists of satellite gears with 36 teeth and a ring gear with 93 teeth. ...Thanks to Scott...

This is a simple yet effective 3D printable planetary gear for 5208 brushless motors. Gear ratio is 4:1, quialifying the resulting actuator as a semi-direct drive. I personally use DYS gimbal motors and need more torque than they can provide, while...

A planetary gear reducer that can be used as a vernier is provided. The transmission ratio is 1:24. This reducer was applied to the G600 microscope stand https://www.thingiverse.com/thing:3951987. When setting up satellite gears, note their correct...

Example: one stage: 1:5, two stages: 1:25, three stages: 1:125 and four stages: 1:625Required Openscad libraries, check thank list below.--- Many thanks to Revar Desmera, the creator of the Openscad BOSL library - https://github.com/revarbat/BOSL---...

If you want to be able to replicate what Levi Janssen did, you can use badSplitRingPlanetary.scad which allows to remove the standard parity constraint on the number of teeth for a planetary drive. (In theory the sun on the second stage violate one...
