Embodiment 1
[0079] It can be seen from the above results that in order to suppress the wear caused by the corners of the flow path 2f, the effective measure is to increase the small radius portion 2d and avoid the contact between the corners of the flow path 2f and the inner spherical surface 4a of the piston 4. At this time, it is necessary to consider the surface The local concentration of pressure and the increase of average surface pressure.
[0080] In this embodiment, in order to suppress the surface pressure between the outer spherical end 2a" and the inner spherical surface 4a, the corner of the outer spherical end 2a" is obtuse, or the chamfer R is provided so that it does not become an edge. According to this configuration, it is possible to avoid contact between the flow path 2f and the inner spherical surface 4a, and to reduce abrasion due to the outer spherical surface end portion 2a" where surface pressure tends to concentrate.
[0081] In addition, as described above, since...
Embodiment 2
[0086] Next, a test was also performed on an example in which the sizes of the spherical portion 2a and the inner spherical surface 4a were the same as in Example 1, but the lubricating oil flow path 2f was different. In Example 2, the hole 2fb was used as the flow path 2f.
[0087] Also, in the case where the small-radius portion 2d is completely surrounded by the outer spherical surface of the spherical portion 2a, it is difficult to provide a flow path between the small-radius portion 2d and the surface 2a' using a groove. In this case, if the flow path 2f is provided by using the hole 2fb, the outflow and inflow path of lubricating oil can be ensured.
[0088] In this example, a hermetic compressor provided with a circular hole 2fb with a diameter of 1mm was produced, and when an actual equipment test was carried out, it was found that the ball joint structure did not disengage, and that the outer spherical end 2a" was not seen. Aggravated by excessive wear, the result of...
