Materials for gear production Metal FERROUS METAL NONFERROUS

Materials for gear production

Metal FERROUS METAL NON-FERROUS METAL � Steel � Stainless steel � Cast iron � Powder Metal � Aluminum � Titanium � Brass

Non metal gears PLASTIC COMPOSITE � Polycarbonate � ABS � Nylon � Delrin � Polyethylene � Polyamides � Carbon Fiber � Fiberglass � Kevlar � Thermal plastic embedded with fibers

Selecting the correct material PLASTIC � Low production cost � Good strength to weight ratio � Multiple material options to meet the needs of the gearbox. � Quiet mechanical operation COMPOSITE � High production cost � Highest strength to weight ratio � Multiple composite options � Quiet mechanical operation � Subjective to mechanical wear

Selecting the correct material METAL � High strength � Long life � Lubricated to prevent wear � High RPM capability � Moderate manufacturing needs � Brass gears are soft and quiet. � Aluminum gears are harder and have more mechanical sound than brass � Steel gears are the hardest and have more mechanical sound.

Selecting the correct material WHICH MATERIAL? � Gears should be selected based upon the use of the gearbox. � RPM, weight and temperature are just as important to considerations as the load in which the gears will transfer � Manufacturing ability and project cost often dictate the materials that gears are made of. � Choose the material that best meets the need of your project.
