• It is known that assembly errors, often referred as misalignments, have significant influence on gear dynamics and ultimately noise generation. However the study of effects of assembly errors on the dynamic response for non-parallel axis gears, primarily hypoid or spiral bevel gears has been limited because of their complicated geometry, and time and spatial-varying mesh characteristics. In this study, four types of assembly errors, that are errors of shaft angle, pinion offset, pinion axial position and gear axial position, are examined in the tooth contact analysis of a typical spiral bevel gear pair. The load distribution results are synthesized to obtain the mesh parameters which are then applied to the dynamic simulation to investigate the sensitivity of the dynamic response subject to the assembly errors. This study yields a better understanding of the specific errors controlling the severity of vibratory response in a spiral bevel geared rotor system. The analytical results of this study can be applied to guide the gearbox transmission design improvements.
