Introduction
- Source with great explanation of planetary gears - [1]
- This is good for a geared down extruder for 3 mm filament.
- This may be applicable to vehicle geardown with rubber-on-plastic drive for heavy duty applications up to 1000 lb drive for solar slow traction vehicles
Why?
- Note that he4ingbone gears eliminate the need for a thrust bearing. That is a great point of size.plification when using planetary gears.
- "Here is a design for a low-profile (18mm) stackable gearbox that fits onto a standard NEMA 17 stepper motor. The gearing ratio of 4:1 allows for increased torque and positional accuracy from the motor. Herringbone gears are used to provide smooth power transmission from the stepper motor while eliminating the need for thrust bearings. A flat rotating output platform is also provided to allow for easy mounting of attachments. More details along with a step-by-step guide to designing gears for 3D printing in Autodesk Inventor is provided below."
