The shafts are made of a metal, usually iron or steel. The shafts are molded to a specific form using the casting process and then the required gears are cut out using the needed method such as milling, broaching, hobbing unless they have been forged or cast during the shafts initial manufacturing 4.3 Discuss Materials 1. Aluminum Alloy. Aluminum alloy is used for the housing cast, because it is light, doesn’t rust and has enough strength and durability or last for a long time. 2. Machined Steel. Is used on the gears and shafts because it is sturdy and can withstand the fast rotations and movements it is being put through. The material is also relatively cheap and easy to make. 3.Brass Alloy Is used for the synchronizer gears. That material is used because it doesn’t rust a What is the difference between a spur gear and a helical gear?...
