Abstract: PURPOSE:To improve the accuracy of assembly by generating oil seal performance for separating a low pressure chamber from a high pressure chamber via the application of light shrinkage coupling between a frame and a center shell using a shrinkage coupling tolerance approximately equal to or less than a half of the conventional tolerance, and applying spot weld for fixing the frame to the center shell. CONSTITUTION:As a crankshaft 6 is driven and rotated with an electric motor made of a rotor 8 and a stator 9, an oscillation scroll 2 oscillates to form a compression chamber with a fixed scroll 1. As a result, refrigerant gas drawn into a low pressure chamber 40 is compressed and delivered to a high pressure chamber 41. A sealing vessel is internally divided into the low pressure chamber 40 and the high pressure chamber 41 via the boundary of the shrinkage coupled section of a frame 7c and a center shell 23a. In this case, the shrinkage coupling tolerance of the frame 7c and the center shell 23a is approximately equal to or less than a half of the conventional case for providing light coupling state, thereby generating oil seal performance for separating the chambers 40 and 41 from each other. On the other hand, spot weld 51 is applied for fixing the frame 7c to the center shell 23a.

Abstract: PROBLEM TO BE SOLVED: To provide excellent teeth of an outer gear by specifying a difference in the number of teeth between an internal gear and the outer gear, and setting cycloids in such a relationship that the cycloids expressed by specific equations are rotated and deviated. SOLUTION: Assuming that Z2 represents the number of teeth of an inner gear; Z1, the number of teeth of an outer gear; and (e), an eccentricity between the gears, a difference Z2-Z1 in the number of teeth between the gears is three or more, (Z2-Z1)/Z2 is an irreducible number, and cycloids are expressed by the following equations: X=e.cosθ+R.cosθ.(Z2-Z1)/Z2 and Y=e.sinθ+ R.sinθ.(Z2-Z1)/Z2 in such a relationship that the cycloids are rotated and deviated with respect to each other. The teeth can be obtained in an easy-to- handle position where the position of a bisector of the outer gear is located on an X-axis and a Y-axis according to the rotation and deviation. Good teeth of the outer gear can be obtained in the case where the difference Z2-Z1 in the number of teeth is three or more, thus increasing the thickness of a crescent- shaped seal piece.
