d_test: The diameter of the inherent
orifice restrictor is to be calculated iteratively. In the
first step the load capacity and flow are calculated with
the outer diameter of the bearing and the diameter of the
orifice 2R1=d_test prescribed (equation 12.6 of the book). Next the diameter of the orifice
is derived from the calculated flow (equation 12.4) and should be the same
as d_test, if not, d_test is to be adapted in this
calculator manually. h0: The highest axial bearing stiffness,
self-aligning capability and the minimal flow is obtained
with the smallest film thickness. The required film
thickness depends on bearing deflections and flatness of the
bearing surface and is usually related to the bearing size. |
