Evaluation of mesh stiffness and torsional rigidity in spur gear

Abstract EN

This work aims to investigate the main parameters affecting noise and vibration encountered in spur gears.

They are torsion mesh stiffness and transmission error through a complete cycl.

FJEM 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 mutual 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 torsion.

stiffness incremes in the case of double pairs and decreases in the ease of single fair, Also one the main conclusions revealed that the transmission error varied sinsoidaily.

from double pair mesh to singiepair mmh as to.

the noise effect.
