Effects of Texture Bottom Profile on Static and Dynamic Characteristics of Journal Bearings

Figure 7

Effect of the texture depth on static performance characteristics for smooth/textured journal bearings: (a) the load-carrying capacity (); (b) the maximum fluid film pressure (); (c) the friction coefficient (); (d) the end leakage flow rate (); (e) the attitude angle (); (f) the friction force (). Bearings are lower than that of smooth bearing in the texture depth () ranges. However, the end leakage flow rate () keeps increasing and the friction force () keeps decreasing, respectively.
