Abstract
The invention relates to a bearing shell comprising a first exposed region and a second exposed region, said two exposed regions being formed on the inner surface of the two bearing shell ends. The oil grooves arranged in the two exposed regions are inclined in relation to the central line of the bearing shell, in the direction of flow of the lubricating oil. In this way, the lubricating oil is prevented from escaping in the axial direction in the exposed regions. The invention also relates to a method for producing such bearing shells.
Claims20
A bearing shell with a first crush relief area and a second crush relief area, whereby the two crush relief areas on the inner surface of the two bearing-shell ends are formed, with a sliding surfaces area between the two crush relief areas and with oil grooves, arranged at least in the crush relief areas, wherein the oil grooves in the flow direction of the lubricating oil are oriented at an inclination to the middle line of the bearing shell.
A method for producing bearing shells with a first and a second crush relief area, whereby the two crush relief areas are formed on the inner surfaces of the two bearing-shell ends, with a sliding surfaces area between the two crush relief areas and with oil grooves that are arranged, at least in the crush relief areas, in which boards are separated from a strip stock and then these boards are shaped into bearing shells, wherein the crush relief areas are produced on the strip stock and that the oil grooves are impressed into the strip stock, or into the separated boards or into the shaped bearing shells.
