Волновой редуктор 1:15 с телами качения / Wave reducer 1:15 with rolling elements

A homemade harmonic gearbox with intermediate rolling elements, which are balls mounted in a cage. When the eccentric rotates, the balls fall into the recesses of the housing profile. Since there are 15 balls and 16 recesses, the cage rotates in the opposite direction at a ratio of 1:15. The video shows the formulas for calculating and constructing the profile of such a harmonic gearbox, and an example of its construction is shown.
