Quarter-inch routers use "split shank chucks." They build the motor with a hollow shaft, make a cut at the end so you can squeeze the sides together, and add a nut that lets you tighten the shaft around the bit. The motor shaft is the jaws of the chuck.

Half-inch routers use "three piece chucks." The end of the motor shaft has a cone machined into it. The jaws of the chuck are machined to a cone that matches. As you tighten the chuck nut, the jaws are forced into the cone and tighten themselves around the bit. They can make the hole in the chuck jaws any size they want.
