Embodiment Construction

[0025] The following description will be made with reference to the drawings and embodiments of the scroll compressor of the present invention.

[0026] Fig. 3 is a longitudinal sectional view of the scroll compressor of the present invention, and Fig. 4 is a partially enlarged longitudinal sectional view of the scroll compressor of the present invention. The structure of the scroll compressor of the present invention includes a shell body and a rotating shaft. A shell lower cover 12 is arranged on the inner lower part of the shell body. The shell lower cover 12 is an arc of revolution. The top edge of the lower frame is close to the bottom of the lower frame 14, and the lower housing cover 12 is connected with the lower frame 14 that supports the rotating shaft 122 horizontally. The lower housing cover 12 is sealed and fixed on the lower end of the housing body 110. .

Abstract

A vortex compressor is composed of casing, rotary shaft, and a lower cover connected with the lower machine frame for supporting said rotary shaft and fixed to the lower end of said casing in sealing mode. Its advantages are no need of welding, high concentricity, no deformation of rotary shaft, fast start, and high efficiency.

Description

technical field [0001] The present invention relates to a scroll compressor, in particular to a scroll compressor with a shell lower cover integrally connected with the rotating shaft of the scroll compressor. Background technique [0002] As shown in FIG. 1 and FIG. 2 , an upper frame 113 is welded on the inner side of the shell of the conventional scroll compressor 100 , and a lower frame 114 is welded on the lower part thereof. The casing of the compressor is composed of a cylindrical body 110, an upper cover 111 with its upper end hermetically bonded, and a lower cover 112 with its lower end hermetically bonded. The measuring portion of the upper frame 113 and the lower frame 114 is at least inserted and fixed with more than one welding pin 115, after being inserted into the inside of the housing body 110, the welding pin 115 is fixed by spot welding on the inner surface of the housing body 110. [0003] Between the upper frame 113 and the lower frame 114 that are welde...
