Summary:

ABSTRACT:A new experimental method, that enables to estimate the body and driveline sensitivity to unit transmitting error of a hypoid gear for automotive rear axle gear noise, has been developed. Measurements were made by exciting the tooth of the drive-pinion gear and that of the ring gear separately using the special devices designed with regard to simulation of acceleration and deceleration. The characteristic of this method is to estimate the forces at the contact point of the gears. Estimation of these forces is carried out under the condition that the higher stiffness is provided by the tooth of the drive-pinion gear and that of the ring gear, compared with the stiffness of the driveshafts and that of the propeller shaft et cetera, and relative angular displacement of the torsional vibration between the teeth of the drive-pinion gear and those of the ring gear is constant. This method is effective to analyze a driveline system which transforms relative angular displacement between the drive-pinion gear and the ring gear into the forces at the contact point of the gears, and provides an insight into how each component should be designed to obtain further reduction of rear axle gear noise. Practical applications are also discussed
