Industrial Worm Gearbox / Gear Reducer (Cutaway version)

PART OF MY INDUSTRIAL GEARBOX COLLECTION This is a fully 3D printable version of an industrial worm gearbox / gear reducer. This cutaway version can be used for training purposes, and has a gear ratio of 1:30 Worm gearsA worm gear consists of a “worm” and a “worm gear”. The worm is a gear with a screw-like shape, when the worm turns 360 degrees the worm gear rotates 1 teeth. Worm gear reducers are typically used in applications that requires high speed reduction when space is limited. Another advantage of the worm gear is that “back driving” is nearly impossible. No additional hardware needed! UPDATE 7-16-2018I`ve added a cap that can make the gearbox non-cutaway, see the green parts in the fourth picture. When you want the gearbox to be non-cutaway, you have to print the 2 files named with NON-CUTAWAY.     Print settingsWorm GearSupport: NoInfill: 40 – 60 %Layer height: 0.1 – 0.3 mm WormSupport: MaybeInfill: 40 – 60 %Layer height: 0.1 – 0.3 mm Axle (Rim, Skirt or raft might needed)Support: NoInfill: 40 – 60 %Layer height: 0.1 – 0.3 mm HandleSupport: NoInfill: 40 – 60 %Layer height: 0.1 – 0.3 mm HousingSupport: NoInfill: 20 – 40 %Layer height: 0.1 – 0.3 mm Housing_bottomSupport: NoInfill: 20 – 40 %Layer height: 0.1 – 0.3 mm Housing _topSupport: NoInfill: 20 – 40 %Layer height: 0.1 – 0.3 mm Spacer bigSupport: NoInfill: 20 – 40 %Layer height: 0.1 – 0.3 mm Spacer smallSupport: NoInfill: 20 – 40 %Layer height: 0.1 – 0.3 mm StopSupport: NoInfill: 20 – 40 %Layer height: 0.1 – 0.3 mm NON-CUTAWAY houseSupport: NoInfill: 20 – 40 %Layer height: 0.1 – 0.3 mm NON-CUTAWAY topSupport: NoInfill: 20 – 40 %Layer height: 0.1 – 0.3 mm     The clearances of this model are between 0.2 - 0.4 mm (0.008 – 0.016 inch). You might need to drill out the holes for the axles (9 mm), or sand some of the parts to make them fit.
