Abstract
The demand for high speed, enhanced performance and greater reliable of machineries is increased, prediction and control of gear defects like vibration, noise and diagnosis of same are the primary consideration. In this paper, the static and dynamic behaviour of the spur gear are modelled and analysed using SOLIDWORKS and three dimensional finite element method (ANSYS workbench), respectively. Different stress components for spur gear are evaluated with varying pressures angles, keyway types, i.e., single or double made with both square or rectangular shape and material properties. Minimum stresses are observed in the gear made of 20° pressure angle with double square keyway. It is also found that stress components in the gear decrease with an increase in pressure angle. Similarly, it can be concluded that a single rectangle keyway with 14.5° pressure angle spur gear shows more resistance to free vibration and grey cast iron is the suitable material.
