This paper deals with the determination of the transmission error in spiral bevel gears and its minimization using tooth profile modification in order to reduce noise and vibration of transmission systems. Gears are the primary source of vibrations transmitted through the shaft and bearings to the gearbox housing and adjacent surfaces that emit noise to the surroundings. To increase the level of comfort and due to the legislative requirements, increasing emphasis is being placed on reducing the noise and vibrations of machine components, including transmission systems. This leads to the need to identify noise sources and evaluate them in terms of expected acoustic performance. The quality of the gear meshing can be evaluated by transmission error that is closely related to the noise and vibrations. To evaluate the quality of gears based on transmission error, experimental approaches are used that are costly and require quality equipment. Therefore, it is efficient to determine expected transmission error already at the design stage using numerical methods. In the presented paper, FEM software ANSYS is used for numerical simulation of the spiral bevel gear mesh and the obtained results were used to study the effect of tooth profile modifications on the transmission error.
