Abstract :

This research work on characteristics of an involute gear system including, bending stresses of gears in mesh. Gearing is one of the most critical components in a mechanical power transmission system, and in most industrial rotating machinery. The variations of the whole gear body stiffness arising from the gear body rotation due to bending deflection, shearing displacement and contact deformation. Many different positions within the meshing cycle were investigated. Transmission error is considered to be one of the main contributors to noise and viation in a gear set. Transmission error measurement has become popular as an area of research on gears and is possible method for quality control. To estimate transmission error in a gear system, the characteristics of involute spur gears were analyzed by using the finite element method. The contact stresses were examined using 2–D FEM models. The bending stresses in the tooth root were examined using a 3–D FEM model
