Abstract
A sleeve bearing system is provided in which wear is reduced and thrust loading capabilities are offered. An inner ring is secured tightly to a rotating member via a collar. The inner ring forms a plain or sleeve bearing with a bearing set. The bearing set may be supported within a housing designed to be fitted to a machine frame. A thrust extension of the bearing set interfaces with the collar to transmit thrust loading on the rotating member to the bearing set and housing via the inner ring and collar.
Claims36
A bearing assembly comprising:
- a sleeve bearing set having a housing and an inner sleeve, the inner sleeve having a central aperture forming a first bearing surface and a thrust surface;
- an inner ring configured, to fit within the inner sleeve, the inner ring having an outer second bearing surface configured to bear against the first bearing surface to support the inner ring rotationally with respect to the inner sleeve, the inner ring having an inner surface configured to receive a mechanical member;
- and
- a collar configured to be fitted to the inner ring adjacent to the bearing set to secure the inner ring to the mechanical member and thereby to prevent relative movement between the inner ring and the mechanical member, the collar being configured to abut the thrust surface to transfer thrust loading from the mechanical member and inner ring to the bearing set.

A bearing assembly comprising:
- a sleeve bearing set having a housing and a polymeric inner sleeve, the inner sleeve having a central aperture forming a first bearing surface;
- an inner ring configured to fit within the inner sleeve, the inner ring having an outer second bearing surface configured to bear against the first bearing surface to support the inner ring rotationally with respect to the inner sleeve, the inner ring having an inner surface configured to receive a mechanical member;
- and
- a collar configured to be fitted to the inner ring adjacent to the bearing set to secure the inner ring to the mechanical member and thereby to prevent relative movement between the inner ring and the mechanical member.

- a polymeric bearing housing supporting the bearing set;
- an inner ring configured to fit within the inner sleeve, the inner ring having an outer second bearing surface configured to bear against the first bearing surface to support the inner ring rotationally with respect to the inner sleeve, the inner ring having an inner surface configured to receive a mechanical member;
- and
- a collar configured to be fitted to the inner ring adjacent to the thrust extension to secure the inner ring to the mechanical member and thereby to prevent relative movement between the inner ring and the mechanical member, and to transfer thrust loading on the mechanical member to the bearing set via the thrust extension.
2 more elements
A kit for securing a sleeve bearing assembly to a mechanical member, the sleeve bearing assembly including a housing, the kit comprising:
- an inner sleeve comprising:
- a central aperture forming a first bearing surface;
- and
- an annular thrust, extension bearing axially against the housing;
- an inner ring configured to fit within the inner sleeve, the inner ring having an outer second bearing surface configured to bear against the first bearing surface to support the inner ring rotationally with respect to the inner sleeve, the inner ring having an inner surface configured to receive a mechanical member;
- and
- a collar configured to be fitted to the inner ring adjacent to the bearing assembly and thereby to prevent relative movement between the inner ring and the mechanical member, wherein the collar is further configured to contact the thrust extension to secure the inner ring to the mechanical member to transfer thrust loading on the mechanical member to the bearing set via the thrust extension.
4 more elements
