BIGRRR 18:1 CNC Gear Set with Bearings
High grade alloy gears with bearings on the Spur gear and Sector gear with reduction of gear resistance of about 60%
This Gear set is the same ratio as standard gearboxes.
These gears will require shimming.
For the Experts:
Bevel Gear: has three layers of teeth: the inner layer of 10 teeth; the outer layer is 30 teeth; the middle is 4 teeth;
Spur Gear: has two layers of teeth: the inner layer is 20 teeth, and the outer layer is 39 teeth;
Sector Gear: has two layers of teeth: the inner layer is 32 teeth, and the outer layer is 16 teeth;
Count the gear for example:
Pinion Gear (3.0 laps) → Bevel Gear (1.0 laps)
Bevel Gear (3.9 laps) → Spur Gear (1.0 laps)
Spur Gear (1.6 laps) → Sector Gear (1.0 laps)
3.0 x 3.9 x 1.6 = 18.72
