The recommended resources for the worm are hardened steel and bronze for the worm equipment. However, dependent on the software, unhardened metal worms can operate sufficiently and far more economically on solid iron worm gears rated at 50%. In addition to metal and hardened steel, worms are available in stainless steel, aluminum, bronze, and nylon worm gears are obtainable in metal, hardened steel, stainless metal, aluminum, nylon, and non-metallic (phenolic).
As the most compact modest precision gear system, worm gear sets give large reduction ratios in a really modest area. Worm gear sets transmit motion in between disjoint appropriate-angle shafts and give the quietest, smoothest running operation of any gear sort.
