Breaking down what is worm and worm wheel
If you've ever peeked inside a heavy-duty gearbox or wondered how a massive elevator stays in place without falling, you've likely encountered the mechanics of what is worm and worm wheel sets. It's one of those engineering staples that looks a bit strange compared to standard gears, but it handles some of the toughest jobs in the industrial world. Unlike the gears you might see in a clock—where teeth just mesh together on the same plane—this setup uses a screw-like shaft to drive a wheel. It's a clever way to change the direction of motion while packing a massive amount of power into a small space. ...
