Modelling the trochoidal gearing with respect to the uniform teeth wear

W referacie przedstawiono model teoretyczny zmodyfikowanego zazębienia trochoidalnego, które jest stosowane w pompach systemu Gerotor. Pompy Gerotor należą do maszyn wirujących, których kinematyka oparta jest na zasadzie...

THE TRIBOLOGICAL CHARACTERISTICS OF Al-Si/GRAPHITE COMPOSITE

The paper presents the results of tribological research on AlSi12CuNiMg/5.7 wt.% Gr aluminium composite material (containing graphite particles in the amount of 5.7% wt.%) and on its matrix. This composite is used as hig...

THE EFFECT OF HELICAL GROOVE PRESENCE ON THE TRIBOLOGICAL PERFORMANCE OF JOURNAL BEARINGS

The hydrodynamic bearings could suffer critical damages operating in contaminated environments that cause machine breakdown. In such hard operating conditions, hydrodynamic bearings with grooved journals are less sensiti...
