Single Tooth Involute Gear 2 - Educational model

My Educational Mechanical Examples Series This model is one of my educational mechanical mechanism examples on 80mm x 80mm base plates. You can find all models of the series in this collection => [Mechanical Mechanism Examples] The present model This model shows a single-tooth involute gear meshing with an eleven-teeth involute gear, resulting in a reduction ratio as large as 1:11 in a compact volume. Brief Description The smaller gear in this model is made of two heart-shaped plates stacked together with 180-degree phase differences. Each heart shape represents a single-tooth involute gear, which has been already introduced in the other model. A single plate alone cannot maintain continuous meshing, so by stacking two plates with a shifted angle, we keep at least one of the two plates always in contact with the mating gear. The larger gear looks completely different from the standard involute gears. However, each layer of this gear is indeed an involute gear even though it is largely
