Abstract
A bearing bush configured to support a journal of a journal cross of a cardan shaft includes a cylindrical circumferential wall that radially delimits an interior for receiving rolling elements and the journal and includes a base axially delimiting the interior. The base has a central holder configured to receive a slip disk for contacting the journal. The base may include a conical portion extending from the cylindrical circumferential wall and a flat central portion, and the holder may be formed as a depression in the flat central portion. Also a journal bearing assembly including the bearing bush.
Claims10
A journal bearing assembly of a cardan shaft comprising:
- rolling elements,
- a journal, and
- a bearing bush including:
- a cylindrical circumferential wall having an interior surface radially delimiting an interior for receiving the rolling elements and the journal, and
- a base having an interior surface axially delimiting the interior, the interior surface of the base having a flat central portion and a conical portion extending radially outward from the flat central portion,
- wherein the base includes a central holder and a slip disk received in the central holder for contacting the journal,
- the journal having a flat central end surface abutting against the slip disk, wherein the central end surface has a greater roughness than a roughness of the flat central portion of the interior surface of the base.
A journal bearing assembly of a cardan shaft, comprising:
- a journal of a journal cross of the cardan shaft, and
- a bearing bush configured to support the journal, the bearing bush comprising:
- a cylindrical circumferential wall radially delimiting an interior for receiving rolling elements and the journal,
- a base axially delimiting the interior, and
- a slip disk centrally mounted to the base and configured to be contacted by the journal,
- wherein the base includes a conical portion between the cylindrical circumferential wall and a flat central portion,
- wherein the slip disk is mounted on the flat central portion,
- wherein the journal has a flat central end surface abutting against the slip disk, and
- wherein the flat central end surface has a greater roughness than a roughness of the flat central portion.
A journal bearing assembly of a cardan shaft, comprising:
- a journal of a journal cross of the cardan shaft, and
- a bearing bush configured to support the journal, the bearing bush comprising:
- a cylindrical circumferential wall having an interior surface radially delimiting an interior for receiving rolling elements and the journal,
- a base having an interior surface axially delimiting the interior, and
- a slip disk centrally mounted in a depression in the base and configured to be contacted by the journal,
- wherein the journal has a flat central end surface abutting against the slip disk, and
- wherein the flat central end surface has a greater roughness than a roughness of a bottom of the depression.
