Modern trends in the use of hydraulic drives of active working bodies of self-propelled equipment require new rotary hydraulic machines, particularly planetary. The processes occurring in hydraulic machines are associated with the movement of the working fluid through the channels of their distribution systems. Proposed the choice of a rational form of working windows of distributors in the design of systems for distributing the working fluid of planetary hydraulic machines, depending on their technical characteristics, purpose, production conditions, etc. A structural and functional diagram has been developed for determining the flow area of a distribution system with different shapes of distribution windows, which allows modeling the process of changing the flow area. The analysis of the output characteristics of the distribution systems has been carried out, making it possible to make a rational design decision on the choice of the shape of the windows of the projected distribution system of the planetary hydraulic motor. It has been established that distribution windows made in the form of a segment are the most functional while being very complex in manufacturing technology. Distribution windows, made in the form of a hole, are the most technologically advanced but have a flow area three times less than segment ones. |
