involute gearbearing
Description
This Is A Gear Bearing Or Planetary Gear That I Designed With Solidedge St8. The Gears Have An Involute Arrow Gearing. The Ring Gear Has 21 Teeth, The Planet Gears And The Sun Gear Have 7 Teeth. There Are Two Different Sizes Of The Gearbearing, A Small And A Large Version. The Large Version Was My Initial Design With A Ring Diameter Of 131.3Mm(1.17") And A Height Of 15Mm(0.59"). The Small Version Is Exactly The Same Design Just Skaled Smaller In Order To Print It Also In Smaller Sizes. It Has A Ring Diameter Of 53Mm(2.09") And A Height Of 10Mm(0.39"). The Large One Is Printable From 60%(Approximately 80Mm(3.15")) Upwards, On My Printer. I Like To Use These Kind Of Gear Bearings For My Filament Holder, To Make Sure The Printer Can Easily Pull Filament Of The Spool.
