Abstract

PURPOSE: To reduce the starting load of a bearing and its wear by forming a convex section in the bearing groove, narrowing the groove width, and improving the degree of fluid lubrication.
CONSTITUTION: The dot-patterned convex sections 5 are formed in the pump-in type groove 3 of the journal bearing 1 and each width of the grooves 2 is narrowed. Consequently, lubricant is easy to cover the grooves 2 and the tips of the convex sections 5 and the degree of fluid lubrication is improved completely. In addition, when the shaft 4 which engages with the bearing 1 stops rotating, the lubricant in the groove 3 increases. As a result, the starting load of the bearing and its wear are reduced.
