Abstract:
1. A split-type sliding bearing adapted for mounting on a crankshaft for an internal combustion engine, comprising: a pair of semi-cylindrical bearing bodies which are combined with each other to form a cylindrical body, and which are incorporated in a split-type bearing housing, having a cylindrical bearing retaining bore and comprising a pair of housing halves each corresponding to the respective semi-cylindrical bearing body when the semi-cylindrical bearing bodies are incorporated in the cylindrical bearing retaining bore, wherein the split-type bearing housing comprises one housing half having a lower stiffness, and another housing half having a higher stiffness, wherein the housing half of lower stiffness supports one of the pair of semi-cylindrical bearing bodies, which is a first semi-cylindrical bearing body, and the housing half of higher stiffness supports the remainder of the pair of semi-cylindrical bearing bodies, which is a second semi-cylindrical bearing body, and wherein the first semi-cylindrical bearing body and the second semi-cylindrical bearing body have the following dimensional relationship before they are incorporated in the bearing housing consisting of the pair of the housing halves: whereby, in an incorporated condition, the circumferential end parts of the first semi-cylindrical bearing body and the circumferential end parts of the second semi-cylindrical bearing body abut, an inner surface of the first semi-cylindrical bearing body and an inner surface of the second cylindrical bearing body are in alignment with each other at said abutting circumferential end parts and deformation between the pair of housing halves results in a stepped difference at an outer surface of the first semi-cylindrical bearing body and an outer surface of the second semi-cylindrical bearing body at said abutting circumferential end parts due to differences between the lower stiffness and the higher stiffness.
