A simple 3 gear design Design to be practical and easy to access and assemble. All assembly from Z axis. Specification: - Gear material - cast iron/brass/copper/steel - Gear Ratio : Gear 1(10 teethes) to Gear 2 = 8.00 : 1 or, Gear 1 (12 teethes) to Gear 2 = 6.667 : 1 Gear 2 Big to small = 8.00 : 1 Gear 2 (small) to Gear 3 = 8.00 : 1 Option 1- Gear 1 (10 teethes ) At approximate 619 rpm or 10.33 rev/second at motor for 3 second for 1/2 revolution at output shaft. Option 2- Gear 1 (12 teethes ) At approximate 540 rpm or 9 rev/second at motor for 3 second for 1/2 revolution at output shaft. - Included Enclosure design for manufacturing processes : 1- Injection molding 2- Machining - Drilling/Tapping 3- Gear 2 and Gear 3 are hold together using 1 aluminium plate - Required stamping and bending. 4- Copper bushes are press into the aluminium plate for smoother gear rotation. 5- A little bit redesign at the valve's shaft area : - Added 1 bearing and 1 oil seal. 6- All the gears are inline at ±48 deg 7- The aluminium cover can be extend to the gear at the motor. B.O.M 1) Gear 1 - Dia 8.00mm x 6.5mm Thickness , 10 teethes - Minimum teeth and minimum diameter for small ratio and maintaining strength. 1-1)Gear 1 - Dia 10.00mm x 6.5mm Thickness , 12 teethes - Maximum teeth and minimum diameter for small ratio and maintaining strength. 2) Gear 2 - Dia 60.00mm x 33.0mm Thickness, 80 teethes/ 10 teethes - Maximum diameter and teeth while not interfering with 3rd gears shaft. 3) Gear 3 - Dia 60.00mm x 8.00mm Thickness, 80 teethes - Maximum size and teeth that can fit in the grey/black housing. 4) Copper Bush 5) Valve shaft 6) Aluminium Cover 7) M3x10 screw 8) M4x12 screw **Additional assembly file for 12 teethes and 10 teethes uploaded for reviewing and comments
