Gearboxes let engineers adjust servomotors’ operating speed and resulting torque. But understanding the two major types will lead to lower costs and better performance. Engineers have long used ...

Much as mountain bike technology has advanced since the days of friction shifting and elastomer shocks, most MTBs are still equipped with dangling, fragile rear derailleurs and dirty chains. Switching ...

This article was updated Feb. 28, 2023. It was originally published March 1, 2000. Planetary gears can supply high levels of torque and high-speed reduction. They are also relatively compact compared ...

In this video, I explain what a Lenco planetary transmission is and its purpose. I will detail how planetary gear sets work ...
