The steel can be used for high strength worm gears (worm wheel) and steel may be plain carbon steel or alloy steel. The steel gears are usually heat treated so as to combine correctly the toughness and tooth hardness.
The phosphor bronze is trusted for worms drive so as to reduce wear of the worms which is excessive with cast iron or steel.
Worm gear pieces are usually used to lessen speed and increase torque. Since the worm drive undergoes more contact pressure cycles compared to the worm equipment, the worm drive is usually of a better material.
• Cast iron provides strength and simple manufacture.
• Cast steel provides less complicated fabrication, strong working loads and vibration resistance.
• Carbon steels are inexpensive and solid, but are vunerable to corrosion.
• Aluminum can be used when low equipment inertia with some resiliency is necessary.
• Brass is inexpensive, easy to mold and corrosion resistant.
• Copper is easily shaped, conductive and corrosion resilient. The gear’s power would increase if bronzed.
• Plastic is inexpensive, corrosion resistant, calm operationally and may overcome missing tooth or misalignment. Plastic-type material is fewer robust than metal and is susceptible to temperature alterations and chemical corrosion. Acetal, delrin, nylon, and polycarbonate plastics are normal.

This 27 tooth brass worm gear will be used in combination with a worm gear to create a 27:1 reduction in speed while also changing the orientation of the rotating axis by 90 degrees. This gear fastens to a 1/4″ shaft using a specialised 1/4″ D-hub to be utilized with 1/4″ D-shaft.

The manufacturing methods of worms are roughly divided among cutting, heat treated and ground after cutting and rolling. And for worm wheels, they might be roughly divided among cutting pearly whites, cutting teeth after casting, and tooth cutting after the outside rim is cast around the guts of the blank.
