Reduction of noise and vibration in gear drives is a hot topic of research to which many researchers have devote their efforts. Transmission errors are the main source of noise and vibration of gear drives. The achievement of a favorable shape of the function of transmission errors of low level is the precondition for the reduction of noise and vibration of a gear drive. The proposed approach is based on the following ideas: (a) application of a predesigned function of transmission errors for absorption of linear functions caused by misalignments, (b) localization of bearing contact for avoidance of edge contact, and (c) simulation of meshing and contact of unloaded and loaded gear drives as the test of developed machine-tool settings. The proposed ideas have been applied for various types of gear drives and have been tested experimentally for spiral bevel gear drives. Design of gear drives with reduced noise has been computerized by application of computer programs.
