Slide bearing

摘要

Provided is a slide bearing with which friction-reducing effects can be obtained and the total volume of effluent oil can be limited. A slide bearing in which halved members made by dividing a cylinder in two in a direction parallel to the axial are disposed vertically, wherein narrow grooves are provided at the ends of the slide bearing in the axial direction, the narrow grooves extending in the circumferential direction from the mating surface on the downstream side of the rotation direction to a specified bearing angle is an angle rotated in the range of ≧0 degree to ≦90 degrees from the mating surface on the downstream side in the rotation direction (bearing angle of 180 degrees) towards the upstream side in the rotation direction. In other words, the bearing angle is the range of 180 degrees to 270 degrees.

1. A slide bearing in which halved members made by dividing a cylinder in two in a direction parallel to an axial direction are disposed vertically,
wherein narrow grooves are provided at an end of the lower halved member in a circumferential direction from a mating surface on a downstream side of a rotation direction to a specified bearing angle, wherein the specified bearing angle is an angle which is rotated in the range of ≧0 degree to ≦90 degrees from the mating surface on the downstream side of the rotation direction, and wherein a length of each of the narrow grooves is from the mating surface on the downstream side of the rotation direction to a place of an upstream side where an oil film thickness becomes minimum.
