  　　Although worm gears are one of the oldest gear systems, modern worm gear sets produced using the latest CNC machines, inspection equipment, and material technology are providing innovative, reliable, high-performance solutions for a wide variety of applications. They can be found in large coal mills in power plants, and hold-down mechanisms in steel mills, and they provide high-precision solutions for machinery and equipment that require the highest level of positioning accuracies, such as rotary tables and machine tools.

  　　Double-lead or duplex worm gears are specialized gear sets that allow the backlash to be adjusted to the desired amount over the life of the gear. They are manufactured with two leads, one short and the other long. The result is that the thickness of the worm thread increases from one end to the other. If the worm moves in the axial direction when meshing with the worm gear, the backlash between them can be adjusted to the desired amount.
