<P>PROBLEM TO BE SOLVED: To provide scroll fluid machinery with increased reliability by rigidly and easily holding the bearings of a drive crankshaft or a pin crankshaft as the self-rotation prevention mechanism of a swing scroll. <P>SOLUTION: Bearing storage parts 11m and 36a fitted to a swing scroll 11 side through a second rolling bearing 19 and having one side opening to at least one scroll side are installed at crank parts 22 of crankshafts 22 and 23 rotatably pivoted on a fixed scroll 3 through a rolling bearing 20. The rolling bearings are stored in the bearing storage parts, and screw parts 11b and 36b are formed on the peripheral faces of openings of the bearing storage parts. At least the outer rings of the rolling bearings are positionally held by bearing holding members screwed into the screw parts. <P>COPYRIGHT: (C)2003,JPO |
