Scroll hydraulic machine

Abstract

Abstract PURPOSE: To make alignment between a coupling and a scroll so easy as well as to facilitate assembly operation for the coupling by clamping the coupling to one side of both driving and driven scroll, and also clamping a connecting arm, engageable with two circumferential position, to the other side. CONSTITUTION: A driving scroll 19 is housed in a vessel 1 of a hydraulic machine, and the driving shaft 26 solidly installed in the end plate 19a is supported on an upper bearing housing 5. And, a driven scroll 32, having a spiral projecting body 32b to be engaged with another spiral projecting body 13a of the driving scroll 19, is housed in the vessel 1, and the driven shaft 34 solidly installed in the end plate 32a is supported on a lower bearing housing 6. In this case, a torque transferring coupling 37, forming four sets of ribs 39 on the circumference of a ring base 28, is set up in the back of the end plate 19a. Then, each of section U-shaped connecting arms 40 and 41 set up in the end plate 32a is engaged with guide grooves 39a and 39b to be formed between these four-set ribs 39 and thereby both these scrolls 19 and 32 are made so as to be connected to each other.
