GEAR-COG STEP DRIVE WITH MECHANICAL EXCITATION AND ZERO REVERSE EFFORT Russian patent published in 2018 - IPC F16H27/06 B64C13/28 

FIELD: machine engineering.

SUBSTANCE: gearbox has a transmission link in the form of an internal gear engaged on the carrier in the form of a crank and an output link in the form of a female gear. The transmission link is made in the form of a connecting rod with cogs at the ends. One of the cogs is recessed into the calliper groove, the second is at the same end of the connecting rod from its back side, and the third is on the opposite end of the connecting rod. The connecting rod is connected to the carrier so that at least one of the connecting rod cogs is always engaged with the female gear.
