More Information
Summary:The utility model relates to a hydraulic transmission energy conversion mechanism similar to the gear engagement theory, in particular to a gear pump or a gear motor. The utility model is mainly characterized in that flow rate is changed according to the requirements of working condition by changing gear engaging length. The utility model overcomes the defects that the flow rate is not matched with the actual working condition, a plurality of pressure oil is overflowed back, and energy loss is caused. Hydraulic original pieces such as a flow rate valve and relevant reversing valves can be omitted, a hydraulic system can be simplified, and gear pump (gear motor) series can be simplified simultaneously. The utility model is suitable for the field of electromechanical integration machinery.
