Realizing that it’s essentially a cycloidal drive meshed with a planetary gear set, he got to work in CAD and, in seemingly no time, had a design to test. You can see the full results of his ...

Packing a compact design, along with high torque and low-speed outputs, the new SEW PPK and SEW P2.e planetary gear units ...

The videos below show you the theory: the stepper drives a sun gear with two planet gears orbiting, each of which engages a fixed ring of 56 teeth, and an output ring of 58 teeth. Each revolution ...

Specifically, the service identified a single high-speed planetary pinion gear that had fractured. But an internal Safety Investigation Board report -- which has not been made public -- showed ...
