Finish milling of bevel gear teeth with a simple disc cutter is neither economical nor accurate. It may be [...]
The following points highlight the top five methods used for machining gears. The methods are: 1. Formed Tooth Process 2. Template Process 3. Generating Process 4. Bevel Gear Generators 5. Gear Finishing. Method # 1. Formed Tooth Process: The theory of formed tooth process is based upon forming the cutter tooth according to the shape of the tooth space to [...]
The following are the most commonly used methods of manufacturing gears: 1. Casting 2. Hot-Rolling 3. Stamping 4. Powder-Metallurgy 5. Extruding 6. Coining 7. Machining. Method # 1. Casting: Gears are cast in sand moulds, permanent moulds, shell moulds, plastic mould dies and lost-wax moulds. The characteristics of gears produced by casting are same as those of other products made [...]
