Research and development of new type satellite motors and satellite pumps SM with small geometrical displacement, from 5 to 73 cm3/rev, has been conducted in cooperation with Stosowanie Maszyn company from Katowice (manufacturer of motors and pump SM). The improvement of construction of those machines, especially construction of axial compensation and construction of fluid distribution channels have been the main problem of research project nr R0300103.Extensive experimental research of SM machines and complex computer simulation of the deformations of particular elements in those machines, allowed to work out the research methodology of axial compensation and working mechanism commutation. This methodology allow:- to determine correct compensation area in construction of axial compensation mechanism and to determine dimensions of O-rings grooves that delimit this area;- to determine hold down screws arrangement in motor (pump) and to determine correct torque of screw in them;- to determine correct thickness of compensation plates;- to increase the stiffness of collector of motor (pump) without deterioration of pressure drop in channels;- to determine correct assembly axial clearances of rotor and satellites between compensation plates;- to determine diameters of holes in compensation plates of motor and pump.The research proved that the correct construction of axial compensation and of distribution in satellite machines caused the hydraulic, volumetric and mechanical loses to be decreased and also improved durability of satellite working mechanism and compensation plates. This improved total efficiency of motors and pumps.
