摘要： PROBLEM TO BE SOLVED: To make bearing rigidity small in the crank direction, and reduce contact force between a lap of a turning scroll and a lap of a fixing scroll by enlarging a radial clearance of a bearing part for connecting the turning scroll and the crankshaft to a specified value or more. SOLUTION: A fixing scroll fixed to a case and a turning scroll 11 are engaged with each other, and relatively turned to gradually reduce a compression chamber, and an actuating fluid is compressed. For preventing self-rotation of the turning scroll 11, an Oldam ring mechanism and the turning scroll 11 eccentrically turned are rotationally supported on a crankshaft 20. As a crank quantity Δof the crankshaft 20, a radial clearance of a bearing part 12 for connecting the turning scroll 11 to the crankshaft 20 is enlarged by a range of 1.5/1000 to 4/1000. It is thus possible to eliminate a clearance between laps of the turning and fixing scrolls, and it is also possible to improve compression performance.

摘要： PURPOSE:To absorb an installation error in the perpendicular direction to the driving shaft direction, and stabilize oil feed to a bearing by setting a height of a pedestal in which a spherical slide bearing is inserted higher than a bearing part, and setting an inside diameter of the pedestal larger than an inside diameter of a connecting part. CONSTITUTION:When a driving shaft 7 is rotated by an electric motor 3, a turning scroll 5 is turned by rotation of a crank pin 7a and an action of an autorotation preventive mechanism 9 without making autorotation. As a result, capacity of space defined by respective laps 5b and 6b of the turning scroll 5 and a fixed scroll 6 and respective base plates 5a and 6a is reduced, and gas is sucked from a suction hole 6c, and is delivered from a delivery hole 6d after it is compressed. In this case, oil is introduced to an oil feeding hole 7c of the driving shaft 7 from an oil separator through an oil feeding pipe 15 and an oil feeding pipe joint 13 having spherical slide bearings 10 and 12 on both ends. A pedestal 16 is connected to the spherical slide bearing 12, and a height and an inside diameter of the pedestal 16 are set heigher and larger than the spherical slide bearing 12.
