  - TRIBOLOGIA - Rok 2015

  Z uwagi na potrzeby społeczne, a zwłaszcza rosnące zapotrzebowanie na endoprotezy stawów biodrowego i kolanowego oraz uwzględniając fakt, że procesy tribologiczne odgrywają wiodącą rolę w procesie utraty stabilności endoprotez ortopedycznych i decydują o ich trwałości, uznano za celowe przeprowadzenie oceny wpływu implantacji jonowej na zużycie ścierne biostopu Ti13Nb13Zr. Do badań wykorzystano pary trące: nieimplantowany stop...

  - TRIBOLOGIA - Rok 2007

  W artykule przedstawiono krótką charakterystykę oraz wyniki badań tribologicznych wybranych powłok fluoropolimerowych oraz przeciwzatarciowych. Badania zużycia powłok przeprowadzono pod kątem zastosowania w oryginalnym łożysku foliowym smarowanym wodą. Na podstawie analizy wyników wyłoniono trzy powłoki do potencjalnego zastosowania w łożyskach foliowych smarowanych wodą.

  - TRIBOLOGIA - Rok 2010

  W Katedrze Konstrukcji i Eksploatacji Maszyn PG opracowano metodę badania powłok DLC oraz innych (ceramicznych) w układzie kula - płaska powierzchnia obrotowej tarczy ("ball-on-disk"). Układ badawczy składa się z kuli osadzonej w popychaczu łożyskowanym tocznie, poprzez który wywierana jest siła docisku próbek. Kula dociskana jest od góry do płaskiej powierzchni obrotowej tarczy - próbki dolnej (o pionowej osi obrotu). Próbka dolna...

  - Polish Maritime Research - Rok 2019

  Full film hydrodynamic lubrication of marine propulsion shafting journal bearings in running condition is discussed. Considerable computational difficulties in non-linear determining the quasi-static equilibrium of the shafting are highlighted. The approach using two optimization methods (the particle swarm method and the interior point method) in combination with the specially developed relaxation technique is proposed to overcome...

  - MECHANICAL SYSTEMS AND SIGNAL PROCESSING - Rok 2021

  Controllable/active bearings are mainly associated with active magnetic bearings (AMBs), whereas active bearing control is also found in many types of bearings, e.g. fluid, gas and hybrid bearings. The article presents a review of the literature describing the structure and results of studies of active bearings. Active control brings a number of benefits resulting in the fact that their use as a support for rotors becomes increasingly...

  Bearings of propeller shafts are very crucial elements of the propulsion system of each of the ships. The safety of shipping depends on their durability and reliability. The new legal restrictions mean that today we are looking for environmentally friendly solutions. That is why water-lubricated bearings are becoming more and more popular. So, will oil-lubricated shaft bearings belong to the past? The bearing with a white metal...

  • M. Wasilczuk

  - Journal of Friction and Wear - Rok 2015

  Hydrostatic assistance is a commonly used method to improve limited load carrying ability of tiltingpad thrust bearings during transient states of operation of vertical shaft hydro-generators. Despite of special hydraulic equipment (as pumps, valves, etc.), it also requires manufacturing of special recesses/pockets at pad sliding surfaces, into which oil is injected under high pressure. It allows to lift the rotor before start-up...

  Fluid film bearings have been extensively used in the industry because of their unbeatable durability and extremely low friction coefficient. Large bearings supporting shafts of huge and important rotating machines constitute a special group of fluid film bearings since the reliability of crucial systems, like for example electro-energetic system, rely on their trouble-free operation. Large thrust bearings, apart from enormous...
