Improving the output characteristics of planetary hydraulic machines

Abstract

Current trends in expanding the field of application of mechatronic systems with a hydraulic drive of active working bodies of self-propelled vehicles necessitates the creation of new designs of hydraulic machines. For mechatronic systems with a hydraulic drive of the active working bodies of self-propelled vehicles, various types of hydraulic machines are used, but special attention is paid to orbital and planetary hydraulic motors. The crank in this hydraulics machines is a rotating hydraulic field formed by the distribution system of the planetary hydraulic motor. The distribution system of the considered hydraulic motor is one of the main mechanisms determining the stable operation of the planetary hydraulic motor. As a result of the research, design schemes, a mathematical apparatus, and a calculation algorithm have been developed that make it possible to justify the angular arrangement of the working and unloading windows of the moving distributor. The angular arrangement of the working and unloading windows of the moving distributor of the planetary hydraulic motor distribution system is substantiated. A technique has been developed for shifting the distribution window of the movable distributor, which allows to reduce fluctuations in the flow of the working fluid, and as a result, improve the functional parameters of the planetary hydraulic motor.
