  - Mechines Technologies Materials - Rok 2014

  The article describe the design and operation of a prototype of satellite pump and a prototype of satellite motor. In both machines, the operating mechanism consists of a non-circular gear with external teeth (rotor), non-circular gear with internal teeth (curvature), and ten gear wheels which cooperate with the rotor and the curvature. The differences between the commutation unit in the pump and the commutation unit in the motor...

  • P. Śliwiński

  - Advances in Materials Science - Rok 2016

  The paper presents the newest construction of the hydraulic satellite pump/motor. In this study, the fracture of the hydraulic satellite motor working mechanism is investigated. Factors influencing the durability of satellite working mechanism have been described. The durability of the hydraulic satellite motor working mechanism at a load, corresponding to a pressure of 15 MPa supplied with refined rapeseed oil is very low. Analyses...

• Flow of liquid in flat gaps of the satellite motor working mechanism

  Publikacja

  • P. Śliwiński

  - Polish Maritime Research - Rok 2014

  The article describes the methodology and results of investigations of the flow of oil and HFA-E emulsion in flat gaps of the working mechanism of a satellite motor. The flow of liquid in those gaps is turbulent and not fully developed. The article presents two methods of modelling this flow. Method I makes use of the Darcy-Weisbach formula, while Method II bases on the assumption that in the variable-length gaps the flow is turbulent...

• Results of experimental research of hydraulic satellite motor

  Dane Badawcze

  restricted access

  • P. Śliwiński

  The study of the flow rate in the motor and the torque on the motor shaft at low constant speed were carried out.The file contains measurement data of the torque on the motor shaft and the flow rate in the motor as a function of the angle of shaft rotation at various constant pressure drops in the motor.

• The basics of design and experimental tests of the commutation unit of a hydraulic satellite motor

  Publikacja

  • P. Śliwiński

  - Archives of Civil and Mechanical Engineering - Rok 2016

  he article presents an analytical method to design the commutation unit in a hydraulic satellite motor. It is shown that the size of the holes feeding the working chambers and their location on the plates closing those chambers depends on the geometrical dimensions of the working mechanism. The overlap in the commutation unit depends on the rotational speed range. It is demonstrated that the geometrical dimensions of the commutation...

• Influence of water and mineral oil on the leaks in satellite motor commutation unit clearances

  Publikacja

  • P. Śliwiński

  - Polish Maritime Research - Rok 2017

  The article describes the flow rates of mineral oil and water flowing, as working media, through the commutation unit of a hydraulic satellite motor. It is demonstrated that geometrical dimensions of commutation unit clearances change as a function of the machine shaft rotation angle. Methods for measuring the rate of this flow and the pressure in the working chamber are presented. The results of pressure measurements in the working...

• Influence of geometrical and operational parameters on tooth wear in the working mechanism of a satellite motor

  Publikacja

  • P. Śliwiński

  - Scientific Reports - Rok 2023

  This article describes the phenomena affecting the wear of the rotor of the working mechanism in a hydraulic satellite motor. The basic geometrical relationships that allow the calculation of the coordinates of the points of contact between the satellite and the rotor and the curvature are presented. A method for calculating the number of contacts of the satellite teeth with the rotor teeth and of the satellite teeth with the curvature...

• Losses and power balance in hydraulic satellite motor supplied with oil and HFA-E emulsion

  Publikacja

  • P. Śliwiński

  - Rok 2009

  Mineral oil and HFA-E emulsion are liquids which differ in viscosity, density and lubricant properties. Therefore, supplying hydraulic satellite motor with these liquids, differences between quantity of hydraulic, volumetric and mechanical losses are observed. These losses influence efficiency of conversion of hydraulic energy into mechanical energy and thereby power balance of motor. The research of satellite motor has been conducted...
