AI Technical Summary
In existing rotary compressors, the connection method between the vanes and rollers results in uneven distribution of contact stress, leading to increased wear and jamming problems, which affect long-term operational reliability.
A connecting groove with an arc-shaped main body is provided on the outer surface of the roller. The end of the slide is hinged in the connecting groove. By limiting the comprehensive geometric characteristic parameter β of the working cavity diameter, eccentric diameter, eccentricity, arc-shaped main body diameter and connecting groove width-to-diameter ratio to the range of 0.5 to 2.5, the contact stress distribution is improved, the sealing effect is enhanced and the refrigerant leakage is reduced.
It effectively avoids accelerated wear and movement jamming, reduces frictional power consumption, improves the volumetric efficiency and structural reliability of the compressor, and achieves a balance between sealing effect and manufacturing cost.
