ABSTRACT:
The invention discloses means to reduce the noise and vibration that result from gear transmission error produced by variations in the mesh stiffness at different phases of tooth engagement. A substantially constant mesh stiffness is achieved by proportioning the teeth and the field of contact so that the product of incremental tooth length and tooth load per unit length at a given torque load integrated over the field of contact does not vary significantly as the tooth contact lines move across the field. To minimize deviations from the mean mesh stiffness, the teeth are made as flexible as possible and the total contact ratio as large as possible.
