planetary gearbox with helical gears 3d models

Someone wanted to build a small and light gearbox for a stepper motor and increase torque for a direct drive extruder. By: Janth, Link: http://www.instructables.com/i... Bill of materials: - 3* bearings 3mm inner diameter, 7mm outer...

Made this to avoid using bearings and used extra fat teeth to avoid gear slippage from PLA stripping easily under stress. ... Designed for this motor: https://www.amazon.com/dp/B00PNEQKC0 Motor Model: 17HS19-2004S1

... 4. Added more an option: cover out put with 2 bearings, if someones wants :)) (bearing for shaft out put) Other details are not changed from the previous version and of Janth (thanks Janth). All . ...Stl files  are checked with Netfabb.

These gears were modeled using Solidworks with dimensions similar to the laser-cut gears included in the Printrbot package. ...Designed for seamless replacement of existing gears while retaining the same M3 bolts for the small gear and 8mm bolt for the...

A fidget spinner incorporating planetary gear technology offers an innovative design, providing smooth and efficient spinning motion while engaging the user's hands. ...The gears within the spinner work together to transmit torque, resulting in extended...

... gear set-There are 6 external gears and one internal gear. ...It is called epicyclic gear too. If you want to 3d print the models, suggest to use resin material.If you plan to use ABS/PLA material,it is best to modify the 3d models before printing.

Spur gear is added to helical gear. Multipurpose solution. One is drive an secondone is driven gear. The helical gear in the drawing already has rivets on it. ...They can be removed and replaced with another suitable solution.

The specifications used for this unique design include a final ratio of 5.23, a ring diameter of 80, a planetary face width of 10, a height of motor pedestal of 13, rendering of part 5, a radius of ring back of 4, utilization of 4 case screws, a...

Suitable for 3D printing with few supports.Use of ball bearings to make the rotations between the various couplings smoother.

I made a video showing the assembly and comparing FDM and resin prints of this model: The video also has a list of required hardware in the description.

you might need a little sanding to make them rotate.

I design a high-quality Helical Gear 3D printing model with precise geometry and accurate dimensions. ...If you have inquiries regarding my models or require technical assistance, I invite you to reach out to me for support, and I will provide prompt...

This print allows simple attachment of a stepper motor and gear onto a wooden plate. ...The next step involves creating a vertical fixture, while the print was created using a Rep2 Sailfish with 200-micron settings.

Alternatively, fix an outer gearwheel and spin its carrier with the three external ones, resulting in all spinning at triple speed on their axes. Note that involute gearing has no isogonic rotations. Two animations were made using "KeyShot 4.6" to...
