Problems solved by technology
For a two-cylinder rotary compressor, which has two eccentric parts of the crankshaft, two vane springs need to be installed. Since the two eccentric parts are relatively distributed at 180°, when the second vane spring is installed, the rotation When the crankshaft minimizes the compression of the second vane spring, the compression of the first vane spring is the largest at the same time. At this time, the spring force of the first vane spring is the largest, so the first vane spring Difficult to install with significant risk of ejection

The invention discloses a compressing mechanism used for a compressor, an assembling method of the compressing mechanism and the compressor. The compressing mechanism comprises two air cylinders, a crankshaft, two slip sheets, a first spring and a second spring. The crankshaft comprises two eccentric parts. The two eccentric parts are distributed in the circumferential direction of the crankshaft at intervals, and the included angle between the two eccentric parts is 180 degrees. The two eccentric parts are arranged in compressing cavities of the two air cylinders correspondingly, and each eccentric part is externally sleeved with a piston. The two slip sheets can be arranged in two slip sheet grooves in a reciprocating motion mode correspondingly. The first spring and the second spring are arranged in two spring holes correspondingly. One end of the first spring abuts against the corresponding slip sheet so that the slip sheet can be pushed to abut against the corresponding piston constantly. One end of the second spring abuts against the corresponding slip sheet so that the slip sheet can be pushed to abut against the corresponding piston constantly. The elastic coefficient K1 of the first spring is smaller than the elastic coefficient K2 of the second spring. According to the compressing mechanism, the first spring and the second spring can be installed conveniently.
Description
technical field [0001] The invention relates to the technical field of compressors, in particular to a compression mechanism for the compressor, an assembly method of the compression mechanism and the compressor. Background technique [0002] The function of the sliding vane in the rotary compressor is to separate the high-pressure chamber and the low-pressure chamber of the cylinder. The tip of the sliding vane is in contact with the outer diameter of the roller, and performs reciprocating linear motion along the sliding vane groove of the cylinder. It is an important part that makes the tip of the slide plate come into close contact with the outer diameter of the roller during start-up. Generally, the installation method of the vane spring in the compressor is to clamp the vane spring tightly in the spring hole of the cylinder through the installation fixture. Cooperate and press in, so that the friction between the two will fix the slide spring in the cylinder spring hol...
