Abstract
Lozysko slizgowe poprzeczne, zwlaszcza do walów turbin parowych i innych maszyn wirowych, zawierajace cztery segmenty jak w lozysku poprzecznym segmentowym wahliwym. Lozysko posiada cztery nieruchome powierzchnie slizgowe (1,2,3,4) o róznej geometrii, zapewniajace uzyskanie identycznego ksztaltu czterech szczelin smarowych jak w podobnym lozysku z segmentami wahliwymi, w tych samych warunkach pracy. Po obliczeniu ksztaltu szczelin smarnych w lozysku z wahliwymi segmentami odwzorowuje sie ten ksztalt w lozysku wg wynalazku, stosujac odpowiednie przesuniecia srodka promienia wyznaczajacego powierzchnie slizgowe segmentów lozyska o wartosci ?X i ?Y (inne dla kazdego segmentu). W segmentach (3,4) zastosowano dysze (8) do zasilania olejem pod wysokim cisnieniem.
