Gear manufacturing

Gear manufacturing

Gear manufacturing refers to the making of gears.

Materials

The majority of gears are composed of carbon and low-alloy steels, including carburised steels. Among the carburised steels used in gears are 1018, 1524, 4026, 4118, 4320, 4620, 4820, 8620 and 9310. The intended gear use will dictate the material used in its creation. For example gears to be used in food processing are made of stainless steels or nickel-base alloys because of their corrosion resistance.

Gear manufacturing processes

There are multiple ways in which gear blanks can be shaped through the cutting and finishing processes.

Gear Cutting Processes

*Broaching
*Hobbing
*Shaping
*Lapping
*Milling

Gear Finishing Processes

*Grinding
*Honing
*Shaving

Gear Forming (non-cutting) Processes

*Plastic Injection Molding
*Powder Metal Sintering
*Forging
*Casting
*Roll-Forming (Spline Rolling)
