Abstract
A journal bearing assembly includes a journal shaft configured to be mounted in a pulverizer. The journal shaft has a lower bearing receiving surface proximate a lower end thereof, and an upper bearing receiving surface spaced apart from the lower bearing receiving surface axially. A lower journal bearing is mounted on the lower bearing receiving surface of the journal shaft. An upper journal bearing is mounted on the upper bearing receiving surface of the journal shaft. An upper journal housing is mounted on the upper journal bearing for rotational movement relative to the journal shaft. A lower journal housing is mounted on the lower journal bearing for rotational movement relative to the journal shaft. The lower journal housing is mounted to the upper journal housing for common rotation about the journal shaft. The journal bearing assembly has a loading point defined between the upper and lower journal bearings.
