Self-aligning journal bearing

A pump comprising:

• a housing;
• a shaft extending into the housing for rotation about a first axis relative thereto;
• a rotary pump member received on the shaft;
• and
• a bearing assembly received in the housing for supporting the shaft therein, the bearing assembly including a bearing having an axially extending recess, and a journal sleeve received in the bearing recess and radially positioned between the shaft and the bearing, a fixing member for securing the journal sleeve for rotation with the shaft, and dissimilar facing surfaces on one of the journal sleeve and shaft and the journal sleeve and bearing, to accommodate misalignment of the shaft.

A rotary machine comprising:

• a housing;
• a shaft received in the housing adapted for rotational movement about a first axis relative to the housing;
• and
• a bearing assembly rotatably supporting the shaft in the housing, the bearing assembly including a bearing member having a recess extending substantially parallel to the first axis that receives a journal sleeve therein, and the journal sleeve fixed to the shaft for rotation therewith and including a flexible joint connection with the shaft to permit self-alignment of the shaft and bearing.
