Patent ID: 10823186

Abstract:
A pump bearing retainer (1), for a wet-running pump, includes a radially inner section (3) including an inner section surface (9) for a press-fit contact with an essentially cylinder-shaped radial outer surface (29) of a pump bearing (13). A radially outer section (7) includes an annular or essentially conical-shaped outer section surface (17) with a cone angle (θ1) equal to or larger than 45°. An intermediate section (5) extends from the inner section (3) to the outer section (7). The intermediate section (5) includes an essentially conical-shaped intermediate section surface (15) with a cone angle (θ2) smaller than 45°. A longitudinal cross-section area (A) of the inner section (3) is smaller than a longitudinal cross-section area (B) of the intermediate section (5).
