Example Embodiment
[0027] The specific embodiments of the present invention will now be further described with reference to the accompanying drawings.
[0028] Fig. 2 shows the structure of the compressor connecting the pump body and the casing using the present invention, Fig. 3 shows the groove shape of the compressor main bearing in the present invention, and Fig. 4 shows the punch shape of the present invention for punching the casing.
[0029] The coupling method of the compressor pump body involved in the present invention includes two steps of slotting the main bearing and punching the casing.
[0030] Main bearing slotting: Before the compressor is assembled, four stamping grooves with the shape shown in Figure 3 are machined on the annular end face of the main bearing 6 that is in contact with the shell 1. The four stamping grooves are in an orthogonal position. The inner cavity is in the shape of a tetrahedron. The four triangular faces of the tetrahedron are respectively a, b, c, and...
