Cardan transmission without gear wheels has planetary circle pair with small circle connected by ball ring to large circle

摘要

The cardan transmission has a planetary circle pair with a small circle (KK) and a large circle (GK). The small circle is connected by a ball ring to the large circle. Each ball transmits power from the large circle to the small one and vice versa. The small circle has an annular groove for the balls and the large circle has radial ball grooves.
