10:1 Cycloid Heli Gearbox
Description
It'S Always Cycloids With Me Lately, Isn'T It? This Is My Second Attempt At Making A Gearbox Which Fits Motors From A Crashed Rc Heli, The First Which Works Acceptably: Note I Do Not Say *Fly* As Much As "Whirl Its Blades Around Alarmingly". Unlike My Previous Attempts It Has No Preferred Rotation Of Direction. It **Cannot Be Backdriven** -- If You Try And Let The Motor Freewheel, It Will Just Seize! Required Vitamins: * 1 X 625 Ball Bearing * Probably Epoxy, To Hold The Cam In Place * 30Mm M3 And 14Mm M3 Bolts, 4 X M3 Nut * Main Motor And Mounting Bolts From "Sanhuan 8827 Rc Helicopter", Aka Pioneer X8 * Mounting Bolts And Pair Of "A" Or "B" Blades From Above Helicopter * A Mess Of 4.5 Mm Ammunition Four 4.5Mm Balls Are Used To Join The Wobbling Gear To The Output Plate As Shown In Picture 3. A Bunch More Are Used In A Thrust Bearing As Shown In The Cutaway View. Source Files At Http://Burningsmell.Org/3D/Heli/
