and then file more as necessary. The idea is to effectively “sneak up” on the gap. Once the gap is set, you should gently deburr the end gap with another small, fine-tooth hand file. If the end gaps are excessive, you’ll have to purchase a new ring or ring set, so...
Manring found that a constant area slot design had the advantage of minimizing the required discharge area of the slot, the linearly varying slot design had the advantage of utilizing the shortest slot length, and the quadratic slot design had no particular advantages over the other two. Ivanty...
The distribution of deformation was in a ring shape, decreasing gradually from top to bottom. The wear of the piston was mainly concentrated in the position with large deformation, which is consistent with the results of the wear test. Compared with the standard pistons, the maximum deformation ...

Because the oil film on the slipper bottom has a ring structure, the thickness of oil film is estimated by taking three non-collinear spots on the slipper bottom surface. Due to the limitations of the test device itself, this paper selects three points on the most outer circle edge of the...
The virtual prototyping methodology for swash plate type axial piston machines is summarized in the Figure 8 flow chart. The goal is to use the sophisticated TEHD models, which can consider all the features of the machine; part shape and dimensions, along with material and fluid properties to ...

The hybrid model fills the gap between these two extreme models and has been validated by experimental data for thrust washers and hydrostatic bearings [22], although the model is limited under no-revolution conditions in the steady state. Later, the model was extended to include the dynamic ...
