<p>A closely coupled power system assembly is disclosed in which a rotary lobe device (42), such as a pump, blower or a fan, is closely coupled to a variable speed drive (21) or gear-type hydraulic motor. Close coupling is accomplished by incorporating adaption structure for the two counter rotating shaft (44, 46) of the rotary lobe device (42) into the variable speed drive train (61) or hydraulic motor so that bearings (66, 67), gear (62, 63, 64), seals (49) and the like perform a dual function.</p> |
