Gear drive in the box

thingiverse

Gear drive packed securely within its box measures 105 mm in length, 70 mm in width, and 17 mm in height. Transmission ratios are as follows: # 0 - ratio: 1:1 - RPM: 100, gear 1 turns smoothly at a rate of 100 revolutions per minute. # 0-1 - ratio: 2:1 - RPM: 50, gear 2 reduces speed to 50 revolutions per minute with ease. # 1-2 - ratio: 5.33:1 - RPM: 18.75, gear 3 steps down the pace to 18.75 revolutions per minute with precision. # 2-3 - ratio: 16.89:1 - RPM: 5.92, gear 4 slows things further to 5.92 revolutions per minute with consistent performance. # 3-4 - ratio: 59.11:1 - RPM: 1.69, gear 5 takes it down a notch, reaching a speed of 1.69 revolutions per minute with remarkable efficiency. Careful attention is paid to the gearing components, with graphite grease applied to the points where gears touch each other to ensure smooth operation. Shafts on gears are precision-crafted at 5 mm in diameter, while lapping takes place at low speeds for eight hours, with a deliberate change in rotation direction to achieve optimal results. The gear sleeve stands at an impressive height of 10 mm, with the thickness of the gears measuring either 4.5 mm or 5 mm, depending on the specific model.
