原始语种摘要: In this article, a custom-built test apparatus was used to measure the film thickness in a conformal contact consisting of a stationary fixed-incline block and a moving transparent disc. Two groups of grooved block surfaces were used: one with a step at the inlet, and the other without the inlet step. Under parallel-gap conditions, effective load-carrying lubricant films can be found only when surfaces with an inlet step are used, and a partially grooved surface in the inlet region can generate film thickness larger than the fully grooved one. If the outlet land is larger than the inlet land, a thicker film as well as a higher load-bearing capacity will be obtained. In this study, groove shows a negative impact on the hydrodynamic lift. And not all diverging clearance can form the...
