4.2 Discuss Component Manufacture 1. Gears; One can use a process called broaching which uses a toothed tool to shape and cut the material. Also Hobbing can be used to make the gears on a hobbing machine, which specializes on milling machines. The teeth and splines constantly cut through the object made by the cutting tool which is called a hob. The hobbing technique precisely cuts the object till the needed shape of the gear is met. After the cutting, the gears go through grinding, honing and shaving. During grinding, the cutting tool used is the abrasive wheel and as for honing, it is used to improve the shape of the gears. http://en.wikipedia.org/wiki/Gear_manufacturing 2. Transmission Cast The cast is usually made of cast iron or in this case aluminum alloy and is manufactured by the casting process. This process involves a liquid material, such as aluminum alloy, being poured into a hollow mold of the form required made of a different material which will not mix with the liquid. Once the liquid is

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?...
