|2R1: The larger the size of the pocket
2R1 the larger the load capacity and self-aligning
capability of the bearing.
small diameter of the inlet hole 2R2 is favorable with
respect to the self-aligning capability of the bearing
but may cause the pressure to drop locally by inertia
forces. The pressure drop by inertia forces can calculated
with equation (11.4) of the book.
h2: The highest load capacity is
obtained with small h0/h2 ratio which means a relative large
pocket depth h2. A shallow pocket however is needed to
obtain axial bearing stiffness and self aligning capability.
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.
