Abstract A This work aims to investigate the main parameters affecting noise and vibration encountered in spur gears . They are torsional mesh stiffness and transmission error through a complete cycl . FEM was used for the theoretical aspect of the work . It analyzed and formulated all the necessary aspects dealing with mesh stiffness and transmission errors , for single and double pairs of spur teeth in mesh . The experimental part involved , manufacturing of actual spur gears embodied in experimental rig to investigate the parameters mentioned above .The experimental results were compared with those obtained from the theoretical formulations . It is shown that the torsional stiffness increases in the case of double pairs and decreases in the case of single pair , Also one the main conclusions revealed that the transmission error varied sinsoidally from double pair mesh to single pair mesh as to the noise effect .
