'''Harmonic Drives''' also known as strain wave gearing because harmonic drive gears are strain wave gears produced by the harmonic drive companies is a special type of mechanical gear system that can improve certain characteristics compared to traditional gearing systems such as helical gears or planetary gears. They are typically used in industrial motion control, machine tool, printing machine, robotics and aerospace,for gear reduction but may also be used to increase rotational speed, or for differential gearing. | '''Harmonic Drives''' also known as strain wave gearing because harmonic drive gears are strain wave gears produced by the harmonic drive companies is a special type of mechanical gear system that can improve certain characteristics compared to traditional gearing systems such as helical gears or planetary gears.
