IMPROVED JOURNAL BEARING DESIGN

摘要

The present disclosure relates to bearings, for example, an improved journal bearing. A bushing (44) for use with a journal bearing (40) includes: a cylindricarinterior defining an interior bearing surface (46); a longitudinal axis (45) and an internal diameter (ID); a groove region of the interior bearing surface (46) having a length H along the longitudinal axis; and a set of grooves (48) in the grooved region of the interior bearing surface (46), where N is the number of grooves in the set of grooves (48). Each groove is disposed at a helix angle (theta) offset from the longitudinal axis (45) of the bushing (44). The helix angle is approximately equivalent to the following equation: tangent (theta)=(pi×ID)/(N×H).
