HYDRAULIC ROTATING MACHINE |
| 摘要 |
A hydraulic rotating machine adapted to be actuated and rotated by supply and discharge of a working fluid includes a cylinder block to which a shaft is coupled, the cylinder block being configured to be rotate together with the shaft; a cylinder formed to have an opening portion on one end side of the cylinder block, a recessed portion being formed on an inner circumference of the cylinder; and a bush inserted from the opening portion of the cylinder and provided on the inside of the cylinder, the bush having a projection portion filled into the recessed portion by plastic deformation. The recessed portion is formed in such a manner that width along an axial direction of the cylinder becomes smaller toward the depth direction. |
