This updated design upgrades version 1.0 with a key improvement: lighter weight mechanisms. To achieve this, materials were changed and the gearbox case was redesigned. These changes do not impact the functionality of the previous design. This is a five-stage gearbox. Gear Material: MC Nylon (CDR2), core made of Steel 4140; Case Material: Aluminum 6061-T6 with Delrin covers to protect gears and the main system. Other Materials Considering an initial speed of 1000 RPM, and a torque of 0.040 Nm we get: Stage 1: Gear Ratio 3.33:1, Speed 300 RPM, Torque 0.133 Nm; Stage 2: Gear Ratio 4.16:1, Speed 72 RPM, Torque 0.556 Nm; Stage 3: Gear Ratio 4.16:1, Speed 17.28 RPM, Torque 2.3148 Nm; Stage 4: Gear Ratio 4.16:1, Speed 4.1472 RPM, Torque 9.645 Nm; Stage 5: Gear Ratio 4.16:1, Speed 0.995 RPM, Torque 40.187 Nm The gearbox is installed on the Z axle. This design features positioning pins for correct alignment and easy assembly. A fixed shaft ensures a compact design, with gears rotating via bearings over the fixed shafts. The mechanism is reversible. Commercial parts from high-quality brands like Misumi and McMaster-Carr are integrated into this design to reduce manufacturing costs and lead time. This gearbox does not require oil.
