Riveting method for axial piston oil pump slide

CY14-I axial piston oil pump is widely used in hydraulic equipment. This oil pump has the characteristics of simple structure, small volume, light weight and high volumetric efficiency. The disadvantage is that the strength is poor, the sliding surface between the shoe and the swash plate is relatively easy to wear, and the shoe is also detached due to the rupture of the rivet portion of the plunger. As shown in Fig. 1, the spherical head of the oil pump plunger is provided with a steel shoe, which is spherically fitted and riveted on the outside so that the shoe and the plunger are not separated, but the matching spherical surfaces can be relatively rotated.
