Title:
DOUBLE ROTATING SCROLL-TYPE COMPRESSOR AND METHOD FOR DESIGNING SAME
Document Type and Number:
WIPO Patent Application WO/2018/025878
Kind Code:
A1
Abstract:
The present invention is provided with: a driving-side scroll member (7); a driven-side scroll member (9); a pin ring mechanism (15); a driving side bearing (11) that rotatably supports the driving-side scroll member (7); and a driven-side bearing (13) that rotatably supports the driven-side scroll member (9). The center of gravity of at least any one of a driving shaft (6), the driving-side scroll member (7), and the driven-side scroll member (9) is offset by a predetermined distance from rotation centers (CL1, CL2).
The predetermined distance is set such that the sum of the bearing loads brought about by a centrifugal force and a fluid compression is no less than 5% of the dynamic rated load of the driving-side bearing (11) and the driven-side bearing (13).
