Gearbox for 28BYJ-48 stepper motor 5V DC
Description
I create simple gearbox with ratio 1:32 for slow down a movement for 28BYJ stepper motor, 5V DC. This motor can be use a battery so is optimal for outdoor devices, as my turntable camera system, or a camera slider. Material: - 2x M3 bolts, length 35 mm for gears axes, conical head - 3x M3 bolts, length 16 mm for top of the case - 6x M3 nuts, 1 pc for output gear(red), 5 pcs for a bottom case - 1x M5 bolt, length 75 mm (Grinding with a flat pile to 4.8mm, then wet polish to 4.78 mm with toothpaste + sandpaper 240 grade, finish with cloth) I use a drill machine as turning lathe and after 20 minutes I have almost perfect shaft. Shaft dimensions: - diameter 5 mm x length 45 mm - first(output) tooth 0 to 7mm (for output device...) - 0 to 12.3mm is diameter 5mm, but other side have diameter 4.78mm - second tooth from 17.3 mm to 24.3mm (for a geared output wheel) - both edges are piled 1x45° - 2x ball bearings 12.8 x 4.85 mm, width 5mm for a shaft 5mm - 5V DC stepper motor (optional for fully functional electronic component) Gearbox can be completely mounted without needs a stepper motor. Motor can be mounted after then. So you have 2 pieces, a gearbox & a motor.
