HALF-SPRIT BEARING

Japanese Patent JP2018096406

A

PROBLEM TO BE SOLVED: To suppress a leakage amount of a lubricant in a half-sprit bearing including a groove at an inner peripheral face side.SOLUTION: A half-split bearing 10 includes a groove 111 and a groove 112 along a circumferential direction of an inner peripheral face at an inner peripheral face 12 side. A position at an upstream side in a rotating direction of a shaft, of an end in the circumferential direction of the groove 111 is a position having a deflection angle θ1 within a range of 30°-60° when an angle between a virtual line L1 connecting an end at an inner peripheral face side of a mating face 16 and an original point A1 of an outer peripheral face, and a virtual line L2 connecting a position P2 of an end at an upstream side in a rotating direction of the shaft and the original point A1 of the outer peripheral face, is the deflection angle θ1. Further a position of an end at an upstream side in the rotating direction of the shaft, of an end in the circumferential direction of the groove 112 is determined to a position having a deflection angle θ2 within a range of 30°-60°, when an angle between a virtual line L1 connecting the end at the inner peripheral face side of the mating face 16 and the original point A1 of the outer peripheral face, and a virtual line L3 connecting a position P3 of an end at the upstream side in the rotating direction of the shaft and the original point A1 of the outer peripheral face is the deflection angle θ2.SELECTED DRAWING: Figure 1
