Analysis of the Hydrodynamic Lubrication Characteristics of the External Return Spherical Bearing Pair of an Axial Piston Pump/Motor

Figure 9

Influence of the eccentricity on the lubrication of the external return spherical bearing pair. (a) Circumferential distribution of the oil film pressure under different eccentricity components. (b) Axial distribution of the oil film pressure under different eccentricity components. (c) Load-bearing capacity of the oil film under different eccentricity components. (d) Relation between the eccentricity and the coefficient of friction.
