The recommended materials for the worm are hardened steel and bronze for the worm gear. Nonetheless, depending on the application, unhardened steel worms can run sufficiently and more economically on cast iron worm gears rated at fifty%. In addition to steel and hardened steel, worms are available in stainless metal, aluminum, bronze, and nylon worm gears are accessible in metal, hardened metal, stainless steel, aluminum, nylon, and non-metallic (phenolic).
As the most compact modest precision gear program, worm equipment sets offer high reduction ratios in a really tiny place. Worm gear sets transmit movement amongst disjoint proper-angle shafts and offer the quietest, smoothest working operation of any equipment kind.
