20.500.12556/RUL-139017 Trenje batnih tesnil v hidravličnem valju in trajnostni preizkus Friction of piston seals in hydraulic cylinder and long-term test Za prenos moči se uporablja več načinov, eden izmed njih je hidravlični. Take sisteme tvorijo primarne, krmilne in pomožne sestavine ter aktuatorji, med katerimi se največ uporablja hidravlične valje. Diplomsko delo obravnava problematiko trenja, tesnjenja in trajnosti batnih tesnil hidravličnega valja. Iz pregleda literature smo razbrali, da več faktorjev vpliva na lastnosti drsnih hidravličnih tesnil. Zasnovali smo dve preizkuševališči, s katerima smo eksperimentalno pokazali, da oblika in material tesnila vpliva na trenje in trajnost. Dokazali smo, da se sila trenja posameznega tipa batnega tesnila spreminja s hitrostjo. Pri trajnostnem preizkusu treh različnih tipov tesnjenja je pri enem tesnilu prišlo do okvare. Ugotovili smo, da tesnilo z večjo silo trenja bolj tesni, vendar se hitreje obrabi. Various methods are used for power transmission, including hydraulic. Such systems consist of primary, control and auxiliary components and actuators, of which hydraulic cylinders are the most commonly used. The present work addresses the problem of friction, sealing and durability of piston seals in hydraulic cylinders. From a review of the literature, it was found that several factors affect the properties of sliding hydraulic seals. We have developed two test systems that we have used experimentally demonstrate that the shape and material of the seal have an effect on its friction and durability. We have demonstrated that the force of the third type of piston seal varies with sliding speed. In a long-term test with three different types of seals, one seal failed. We found that a seal with a higher frictional force sealed better but wore out faster. hidravlična batna tesnila hidravlični valji trenje puščanje trajnostni preizkusi hydraulic piston seals hydraulic cylinders friction leakage long-term tests true false false [M.
