Abstract:
A hydraulic drive comprising multiple gear motors each having a gear motor output shaft, and a common gear engaged by the output shafts of the multiple gear motors. Each hydraulic motor has a characteristic sinusoidal torque ripple out of phase with the characteristic sinusoidal torque ripple of at least one other hydraulic motor for cancelling torque ripple and thereby reducing the torque ripple at the common gear.
