Abstract
A half bearing for a sliding bearing may include a bearing substrate having at least one relief region provided in a surface of the half bearing, and a substrate adjacent respective end faces of the bearing substrate. The half bearing may further include a polymer in-fill having a non-uniform thickness provided in a filled region, wherein the thickness of the polymer in-fill in the filled region may be greater proximate the respective end face than remote from the respective end face.
Claims21
A half bearing for a sliding bearing, the half bearing comprising;
- a bearing substrate having at least one relief region provided in a surface of the half bearing;
- a substrate adjacent respective end faces of the bearing substrate;
- and
- a polymer in-fill of non-uniform thickness provided in a filled relief region, wherein the thickness of the polymer in-fill in the filled relief region is greater proximate the respective end face than remote from the respective end face.
An engine comprising a half bearing including:
- a bearing substrate having at least one relief region provided in a surface of the half bearing;
- a substrate adjacent respective end faces of the bearing substrate;
- and
- a polymer in-fill of non-uniform thickness provided in a filled relief region, wherein the thickness of the polymer in-fill in the filled relief region is greater proximate the respective end face than remote from the respective end face.
A method of manufacturing a sliding bearing which is a half bearing, the method comprising:
- forming a bearing substrate having relief regions provided in a surface of the half bearing, and
- depositing a polymer onto the bearing substrate in the filled relief region such that a thickness of the polymer in the filled region is greater proximate a respective end face of a bearing substrate of the half bearing than remote from the respective end face.
