The inner sun gear is a rotor with four pairs of bar magnets on its outer circumference. An outer ring gear has ten pairs of magnets, making the ratio of “teeth” between the two gears 10:2.

Before synchronized gearboxes took over, some cars let you choose your next gear in advance with a small lever. It's a ...

Direct Gear Design has been developed for involute gears and is based on the Theory of Generalized Parameters, (Gears with improved characteristics, E.B. Vulgakov, Mashinostroenie, Moscow, 1974.) ...

Design gear macrogeometry for maximum load — possibly with some consideration for NVH, but often not. Determine gear durability based on maximum load and duration only.

His latest creation is a 3D printed planetary gearbox design with a focus on easy assembly and versatile ratio choice. (Video, embedded below.) ...

Similar to the 4-speed, the highest gear is a direct 1:1 ratio, further lightening and simplifying the design. This transaxle also houses a number of specialized features for oval racing.
