Globoid gear
Current version 07.26.2020 with improved design suggestions.
Globoid gears are also known as Double Enveloping Worm, Conedrive, Hourglass are used in rotary actuator as a better alternative to worm gears due to higher torque and better driving efficiency. Zero backlash is done by splitting the gear or the worm in the middle perpendicular to its axis.
