Massive Torque 3D Printed Planetary Gearbox! - Mantis Hacks

Video Description

I'm trying to get 150 Nm ( 110 ft.lb ) of torque out of a 3D printed gearbox! why? well watch and find out! This gearbox design is based on Gabrael Levine's Open Torque actuator: https://hackaday.io/project/159404-opentorque-actuator *My Mistake* the formula for the gear ratio is completely wrong! The outer ring gears 63 teeth not 72 teeth. The formula is 1 + R/S = 1 + 63/9 = 8:1 reduction. *This video is sponsored by PCBWay* : https://www.pcbway.com/ You can support my projects by becoming a member, tipping, using affiliate links below or buying my STL files: *Channel Membership* : https://www.youtube.com/@MattDenton/join *My new channel here* : https://www.youtube.com/@UCqurSywI8rVsuwLJvCuGUkA *Parts in the U.S.* 2020 Extrusion :https://amzn.to/3IHJjbN 2060 Extrusion :https://amzn.to/46UPnHJ 2020 Corner Plates : https://amzn.to/3IHGyar 2020 T Plates https://amzn.to/4f3pEik 2020 Corner Brackets :https://amzn.to/3IIDj2A 2020 Strong Corner Brackets :https://amzn.to/40xwRS5 2020 flat plates :https://amzn.to/44N892E 2020 T Plates :https://amzn.to/40xk7e8 2020 T Nuts M5 :https://amzn.to/4f3Oyyl *Parts in the UK* 2020 Extrusion https://amzn.to/46HmLlx 2060 Extrusion https://amzn.to/46XGbCy 2020 Large Corner Plates :https://amzn.to/4m0BQCS 2020 Corner Plate :https://amzn.to/46oybKI 2020 Corner Bracket :https://amzn.to/3GDJcxl 2020 Strong Corner Bracket :https://amzn.to/45fAaQh 2020 T Plates :https://amzn.to/45inAzS 2020 T Nuts :https://amzn.to/4o1ZlNR ****************************************************************** *STL Files* : https://www.threeding.com/user/mantisrobot ****************************************************************** *Bambu lab* Printers & Filament : https://shrsl.com/4e0j2 *In my opinion the A1 and A1 Mini are the best starter printers on the market when it comes to value for money, ease of use and quality!* The P1S and X1C are incredible engineering printers for hobby and professional use! ****************************************************************** Slice Engineering *DISCOUNT* Code: *MATTD5* Or use this Link: https://www.sliceengineering.com/?p=BJ1aP9UpY ****************************************************************** *PolyMaker Filamnet* : https://us.polymaker.com?aff=661 ****************************************************************** http://www.paypal.me/mantisrobot https://www.amazon.co.uk/shop/mattdenton ****************************************************************** Find me on Social Media ****************************************************************** https://linktr.ee/mantisrobot ****************************************************************** 00:00 Intro/Design 01:26 Planetary Gears 02:07 (Gear Ratio Calcs *WRONG*) 02:52 Project Idea 05:35 Inside the Gearbox 07:37 Test Device 11:30 Testing & Breaking.. 16:16 Testing FDM Gears 21:07 Testing SLS Gears 23:25 Testing Metal Gears 27:06 Test Device V2 28:32 Output Rebuild 31:00 Transparent Gearbox! 34:30 Big Weights! 36:35 Weight Test 1 37:36 Weight Test 2 38:40 Weight Test 3 40:00 Weight Test 4 40:56 Weight Test 5 43:13 Conclusion
