HYDRODYNAMIC THRUST BEARINGS WITH POLYMER LINING
Journal Title: Tribologia - Year 2016, Vol 268, Issue 4
Abstract
Polymeric linings of sliding surfaces of the hydrodynamic bearings have been used successfully for over 50 years. Despite of their long history of operation and research, they have not become widespread in industrial applications. This fact may be surprising, considering the conclusions that have been published concerning bearing operation and design. This paper summarizes the current state of the art of the tilting-pad thrust bearings with a polymer lining of pad sliding surfaces. Bearing design and the most commonly used polymeric materials are described. The results of the latest theoretical and experimental researches by both bearing manufacturers and at scientific centres are presented. Observed properties of the bearings with polymer lining were compared to the properties of the bearings covered with Babbitt, which is the most frequently material used as lining for hydrodynamic bearings.<br/><br/>

TEMPERATURE OF THE TOP LEVEL SURFACE OF PARTS OF AGRICULTURAL SOIL TILLING MACHINERY. PART II – THERMOVISION MEASUREMENTS
Using a thermal camera, the temperature distribution of the surfaces of ploughshares, subsoil shanks, and cultivator tooth coulters was determined. These parts worked in soil conditions during operation in the field. The...
THE LEVEL OF FRICTION FORCE REDUCTION IN SLIDING MOTION VERSUS THE AMPLITUDE AND FREQUENCY OF TANGENTIAL VIBRATIONS
This work presents the results of comparative analyses of the influence of tangential longitudinal and tangential transverse vibrations on friction force in sliding motion. The analyses were conducted in the function of...
Influence of variation of selected parameters on the reliability of a thrust bearing of a water turbine
Slide thrust bearings are composed of tilting pads. Some bearing pads are rested on sets of springs. Technical parameters of these springs are random variables. The scatter of their values may lead to bearing failure. Th...
