Description
####Featured In These Youtube Videos! - Torque Test: Https://Youtu.Be/Yyocf6Dxfvi - Design And Calculations: Https://Youtu.Be/1Dngqtojmdk ####Where'S Everything Else??? - This Gearbox Has An Older, Nearly Identical Twin, With The Same Outside Form Factor And Different Gear Ratio, It Can Be Found In The Collection! #####Https://Www.Thingiverse.Com/Gear_Down_For_What/Collections/Robotic-Arm ######In This Collection You Will Find: - All Other Related Parts For This Project - Future Updates To This Project - All User Submitted Remix'S - Click That Watch Button To Get Notifications On Future Uploads! ####Assembly - Assembly Instructions Can Be Found In The "Design & Calculations" Youtube Video Above. - Aligning The Gears With The Marks Is Super Important! - Placing The Gears Face Up On A Table, Sort The Planet Gears In Order (1-5) As Shown In The Main Picture And Video, Insert Sun Gears, Wrap The Planets Around The Sun Gears In The Correct Order, Snap Ring Gear #1 On. - Align All Gears With The Marks As Shown In The Video, Then Put The Rest Of The Ring Gears On. You Will Need To Close The Gap In The Rings Before You Spin This Gearset Or Else It Could Skip Teeth And Get Out Of Alignment, For This I Have Included The Ring Closures, That Fits Over All The Rings #####How It Works - Ring Gears #1 & #3 Will Be At The Same Potential And Ring Gears #2 & (Optional #4) Will Be At The Same Potential - The Use Of Ring Gear #4, The 4 Module Planet Gears, And Sun Gear #4 Is Optional And Used To Increase The Amount Of Torque This Gearbox Can Transfer, As Well As To Decrease The Amount Of Load On Each Gear, Think Of It Like A Door Hinge. #### Compatibility - This Gear Box Is 100% Compatible With The Robotic Arm! - This Gear Box Can Be Used In Any Application That The 43.3:1 (From The "Robotic Arm" Collection) Gearbox Is Used In, Because The Outside Of The Rings Gears, And The Width Of The Ring Gears Are Identical. - Do Not Mix And Match Gears Between This Gearbox And The 43.3:1. #### Other Important Info: #####Cad Files?? - I Included The Fusion 360 Project With This, But The Most Recent Version Of This Project Can Be Downloaded In Lots Of Different Formats From This Link: Http://A360.Co/2Wa7Eiz - Feel Free To Create Your Own Modifications And Parts For This Project, And If You Do, Make Sure You Create A Remix And Upload Them, Then I'Ll Add Them To My Main Collection So The Whole Community Can Share Them!
