    Because its a great gear?
    first of all you can use it to switch outpots (because it can slide on the axle)
    you can use it as a linear actuator using half bush piece
    or just use it in gearing down ratios,because there is always just 1 teeh interacting with the other gear,making a 1 : X ratio.
    lets say worm gear to 8 tooth – 1:8

    Also, worm gear can be used as a lock, lets say to lift something and keep it lifted.

    and last but not least… worm gear can be used with any other lego gear 😀

    Wow! What a good answer! Yes, definetly the worm gear doesn´t have any other purpose. I´ll just add one more thing: worm gear can be used to block a mechanism. Do you know that some lifts in the world use a worm gear for security? If there is a problem the worm gear can block the system so that the elevator wont fall.
