Title:
スクロール流体機械
Document Type and Number:
Japanese Patent JP5433831
Kind Code:
B2
Abstract:
In the scroll fluid machine in which an orbiting scroll 10 is pivot-driven by a rotary shaft 102 rotatably supported by the casing 100 and a pivot shaft 104 eccentrically and rotatably supported by the rotary shaft 102, as a method, a self-rotation prevention board 109 is attached to one end of the pivot shaft 104 and a self-rotation prevention pin 110 is attached to the self-rotation prevention board 109. The self-rotation prevention pin 110 is configured to perform an orbiting motion while keeping in contact with the inner surface of the self-rotation prevention bearing (guide body) 111. Further, as another method, the outer periphery of one end 104b of the pivot shaft is configure to perform an orbiting motion while keeping in contact with the inner surface of the balance bearing (guide body) 51. Based on these methods, an eccentrically pivot driven orbiting scroll performs an orbiting motion without whirling, and thus a high-speed operation of the scroll fluid machine is enabled.
