Effect of Involute Contact Ratio on Spur Gear Dynamics
Journal of Mechanical Design, 1999The influence of involute contact ratio on the torsional vibration behavior of a spur gear pair is investigated experimentally by measuring the dynamic transmission error of several gear pairs using a specially designed gear test rig. Measured forced response curves are presented, and harmonic amplitudes of dynamic transmission error are compared above

Dynamic analysis of involute spur gears with asymmetric teeth
International Journal of Mechanical Sciences, 2008Abstract New gear designs are needed because of the increasing performance requirements, such as high load capacity, high endurance, low cost, long life, and high speed. In some applications, such as in wind turbines, the gears experience only uni-directional loading. In these instances, the geometry of the drive side does not have to be symmetric to
