Geometrical Parameters for Distribution Systems of Hydraulic Machines

Abstract

These days, mechatronic systems, which are used in drives for active working tools and undercarriages of self-propelled equipment, are employing hydraulic machines. The most common hydraulic machines are orbital because of their advantages particularly the ability to be mounted directly on drive mechanisms for conveyors, winches, beaters, wheel hubs, etc. The improvement of the output characteristics for hydraulic machines is one of the ways for efficient application of drives with planetary hydraulic motors in mechatronic systems. Therefore, the study of the influence of geometric parameters and working processes inside the distribution systems of orbital hydraulic machines on changing of their output characteristics is a pressing problem. A distribution system under consideration used windows which were made in the form of a groove. The working processes inside such a distribution system have been studied. The findings were used for the development of a mathematical model. It enabled to determine the relationship between the geometric parameters of a distribution system and the output characteristics of an orbital hydraulic machine. The next stage included investigation of how the changes in the design features of a distribution system with various kinematic diagrams influenced on the output characteristics of an orbital hydraulic motor. The kinematic diagrams, which improved the output characteristics of orbital hydraulic motors, have been justified.
