The utility model belongs to the field of gear pump or motor, adopting a combining dynamic-static pressure bearing with high relief ratio designed according to the elastic hydrodynamic lubrication theory. The combing dynamic-static pressure bearing has three structural elements, a static pressure oil chamber, a restrictor, a low-pressure lubrication groove. Compared with the sliding bearings with polytetrafluoroethene steel backing composite materials extensively used both at home and abroad, the utility model has high mechanical efficiency and overall efficiency, wide speed range of high efficiency, low technological requirement and low cost, and convenient optimum design can be performed to determine the speed range of high efficiency of an oil pump in advance.
