The system installation is only in the Z direction, where it's secured to the motor by screwing it into place inside the housing. One helical gear, specifically the Z12 model with a ratio of 1:6,366 N m, plays a crucial role. Another key component is the second helical gear, also Z12, but this time with a ratio of 1:6,366 N m as well. The third and most significant helical gear in the system is the Z63 model with a ratio of 5.25:32,754 N m. Moving on to the internal gears, we have the Z103 helical internal gear with a ratio of 5.15:165,309 N m and the Z20 helical pinion gear with an identical ratio. These two gears work together in three identical pieces. To fix the axis, a helical solar gear known as the Z65 is used, boasting a ratio of 3.25:526,509 N m. The second helical gear, labeled Z100(120), also features this same ratio. Lastly, we have the fourth and final helical gear, which is the Z40 (30) model with a ratio of 0.40:206,392 N m. Components for the system are made from the following materials: * Case: Polycarbonate * Box: ABS * Gears: ZA8 * Shafts: Steel (15CrNi8) * Bearings: standard
