title = "Low noise gear mesh design for e-mobility",
abstract = "The maximum speed of electrical motors for E-Mobility applications keeps increasing. The Power demand is fulfilled with small motor volumes at high top speeds of up to 30.000 rpm. To reach the required torque to accelerate the car, a transmission with high ratio is used. Low design noise for the gear stages are mandatory. Current gear design approaches for automotive transmissions are aimed at input speeds of up to 8.000 rpm. It is known that the noise behavior of a gear stage is not acceptable if the resonance speed of the mesh is reached, at which the gears are oscillating against each other and very high noise emissions are to be expected. This leads to the question if the traditional, sub-resonance speed design for gear meshes is obsolete for future E-mobility applications. This paper discusses different gear designs for sub- and super-resonance operation in an electrical drivetrain. The gear mesh design for a number of variants is covered, a test transmission is used to measure the excitation behavior of the gears under speeds of up to 30.000 rpm.",
