In those mechanisms, a high-torque, low backlash gearbox might be just the thing, and a 3D printable split planetary harmonic drive for the popular NEMA 17 motors would be even better. Right up ...

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 ...

German supplier ZF Group has been developing new vehicle technologies for decades, and is most notable for building ...

The most basic configuration of this is a set of two fixed gears which rotate at a set speed, though many adopt more complex mechanisms, such as the epicyclic planetary gearbox featured in the ...
