Design Optimization of a Spur Gear used in Lathe Machines -A Review Study

Spur gears are an important part of any mechanical engineering component. These are used in applications of power transmissions between two shafts where centre distance between shafts is very less. Gear drives provide higher efficiency that other type of power transmission drives. These are very sensitive in nature too hence a great degree of care must be taken in order to design gears. Current analysis focusses on comparative analysis of spur gears using different kinds of materials other than conventional material of mild steel so that its performance can be improved. In order to conduct the analysis six different materials Aluminium alloy, Gray Cast Iron, Carbon Fibre, E Glass, Epoxy Carbon & Epoxy E Glass have been used. All these materials have been tested on the basis of contact stress being generated. A CAD model of spur gear has been developed in CATIA V5-6 R2017 and Static Structural Analysis has been performed. This data has been compared with numerically solved data. After validation all the materials have been analysed in ANSYS 19.2.
