HYDRAULIC PUMP

Japanese Patent JP2017040217

A

PROBLEM TO BE SOLVED: To provide a hydraulic pump capable of suitably applying a preload to a bearing part while suppressing abrasion of a preload applying member.SOLUTION: A bearing structure 100 includes a bearing part 60A having a supporting part 65 for rotatably supporting a rotating shaft 20 and a preload applying member 70 for applying a preload in an axial direction to the supporting part 65. A first annular member 71A is interposed between the bearing part 60A and the rotating shaft 20 in the axial direction. Therefore, the fist annular member 71A is disposed between the bearing part 60A having the preload applying member 70 and the rotating shaft 20 rotating at high speed. High speed rotation of the preload applying member 70 or the supporting part 65 of the bearing part 60A in accordance with the high speed rotation of the rotating shaft 20 can be restrained by the interposed first annular member 71A. Accordingly, abrasion of the preload applying member 70 can be suppressed by abrasion of the preload applying member 70 and a mating member.SELECTED DRAWING: Figure 2
