“…A similar phenomenon is also found in literature about the EHL and PEHL for the non-greased ellipsoid contact. 7,[30][31][32][33][34][35][36] The elliptical film pressure distribution of the PEHL for the greased ellipsoid contact in the contact zone in Figure 8(a), however, is different from that of the PEHL for the non-greased ellipsoid contact, which has a relatively flattened pressure profile in the central contact zone. 7,[35][36][37] Since the parameters in Table 1 implies that the edges of body 2 have upwards curvature, it is understandable that there exists convex shaped film thickness at the two borders of the contact width direction, as shown in Figure 8(b).…”

“…And the occurrence of the crescent-shaped film of the PEHL case for the greased ellipsoid contact is different from the horseshoe-shaped film of the EHL case for the non-greased ellipsoid contact. 30,32,34 Figure 13 further gives the residual stress distribution at the varied rheology index n. The residual stress varies from the contacting interface of body 2 to its subsurface along the depth z. As seen from Figure 13, the maximum residual stress appears within the subsurface.…”

“…Additionally, he incorporated fundamental theories for rolling bearings in a book [20], which has been widely utilized in subsequent research. Meng et al [21] recently proposed a multi-ellipsoid contact elastohydrodynamic lubrication model for deep groove ball bearings that takes into account the skidding phenomena, as well as the interactions between the bearing's various components. These ball bearing studies demonstrated an efficient method for calculating entrainment velocities using relative rational speeds to the cage.…”
