h0: A high axial bearing stiffness,
self-aligning capability and the minimal flow is obtained
with small film thickness. The minimal value of the film
thickness is limited by bearing deflections and flatness of the
bearing surface and is usually related to the bearing size.
The volume of the groove must be as small as possible in
order to prevent instability. In this calculator a large groove
dept is assumed resulting in a smooth pressure
distribution. Establishing the groove depth and width to
obtain the minimal groove volume requires fem calculation.
The load capacity of the bearing is calculated with equation
12.6 for the outer ring surface and with a homogenous
pressure distribution assumed in the virtual pocket, i.e.
at the inner surface. |
