Condensation Reduction in Squeeze Bearings

The tendency of condensation to appear in square frictionless squeeze bearing systems can be substantially reduced by incorporating grooves in the support rode surface.

The formation of a single or pair of grooves 1 in the longitudinal surfaces of rod 2 (for example, having a square cross-section) in the Figure enables operation of squeeze film bearing 3 at relative humidities of approximately 50% with no condensation. Dynamic stiffness, damping and load handling ability of the squeeze bearing system are negligibly affected by the rod grooves. Groove cross section is approximately 0.010 in. by 0.010 in. and if a pair of grooves is used they are centered on the rod surface approximately 0.080 in. apart.

The beneficial effects of grooves, ridges or orifices occur whether they are in the vibrating or non-vibrating surface of the squeeze bearing.
