Abstract
An electro-hydraulic gear pump power pack [10], including a gear pump [12] and a motor [16], are secured together to form a single assembly. The gear pump [12] has a gear drive [14] that is in rotational communication with a drive shaft [18] extending from the motor [16]. An insert coupling device [20] is constructed of a plastic material and is slip fit onto the drive shaft [18] to dampen vibrations and fluctuations between the shafts [14, 18] and thereby minimize fluid borne noise in the pump [12].
