Abstract
A bearing component and bearing assembly are disclosed. The bearing component includes structure for providing a hard rotation stop, in one embodiment, the anti-rotation structure includes a slot formed in at least one bearing component having a surface for supporting a bearing shell. The slot has a longitudinal axis at an oblique angle to a plane perpendicular to the surface for supporting the bearing shell, in other embodiments, a groove extends radially outward from a surface of at least one component for supporting a bearing shell to a side of the component. The groove has a depth that increases as a function of distance in a direction parallel with a center axis of the component.
Claims15
A bearing component for supporting a bearing, comprising:
- a first component including a first shell supporting surface, a central axis, and a joining surface provided at each end of the first shell supporting surface;
- a second component positioned adjacent at least one of the joining surfaces of the first component and including joining faces and a second shell supporting surface;
- and
- a first groove extending in a direction of the central axis and including a depth extending radially outwardly from the first shell supporting surface of said first component, said depth increasing along said groove from said first shell supporting surface to a side of the first component.
A connecting rod assembly, comprising:
- a rod part including a first bearing shell supporting surface, and a first and second joining surface at each end of the first bearing shell supporting surface;
- a cap part including a second bearing shell supporting surface, and a third joining surface and a forth joining surface at respective ends of the second bearing shell supporting surface;
- and
- a groove in at least the first bearing shell supporting surface of the rod part or the second bearing shell supporting surface of the cap part and extending to a side of the rod part or cap part, wherein when the first and third joining surfaces are fastened together, and the second and forth joining surfaces are fastened together, the first and second bearing shell supporting surfaces form a cylindrical surface, and said groove having a depth in a radial direction from an axis of the cylindrical surface that increases along said groove in the direction of the side.
The connecting rod assembly of claim 16, wherein the first and second grooves are positioned such that they are adjacent one another when the first and third joining surfaces are aligned, and the second and forth joining surfaces are aligned.
A bearing shell, comprising:
- a semi-cylindrical shell having a concave journal supporting surface;
- a convex outer surface;
- first and second joint faces for abutting to joint faces of another semi-cylindrical shell;
- an end face at each side of the semi-cylindrical shell, and
- a tang formed at one of the first and second joint faces and positioned in a radially outwardly direction relative to the bearing shell center axis, said tang having a longitudinal axis at an oblique angle to a plane perpendicular to the concave journal supporting surface.
