  • FIG. 3 is a top view of the frame 2 according to the present embodiment.
  • FIG. 3 shows a state in which the old dam ring 12 is placed on the frame 2.
  • the frame 2 of FIG. 3 has a flat surface 201, an old dam accommodating portion 202, a second old dam groove 203, and a ring-shaped protruding wall formed on the outer end portion of the flat surface 201 of the frame 2 and projecting in the direction of the upper shell 102.
  • a wall 205 is formed so as to project upward from the old dam accommodating portion 202 in order to provide the main bearing 21 between the hollow portion into which the main shaft 6 is inserted and the old dam accommodating portion 202.
  • the thrust plate 22 is arranged on a flat surface 201 inside the protrusion 204, the ring width of which is represented by d.
  • the height of the protruding wall 204 from the flat surface 201 may be set smaller than the thickness of the thrust plate 22 so that the bottom surface of the swing scroll 32 can be slidably supported by the thrust plate 22.

  • the radius r is a radial dimension from the central axis of the main shaft 6 to the side surface of the balancer cover 72
  • the length t is defined as a dimension from the upper surface to the lower end of the balancer cover 72. Since the balancer cover 72 surrounds the upper surface and the side surface of the balancer 71, the radius r of the upper surface of the balancer cover 72 needs to be at least longer than the outer diameter of the rotation locus of the balancer 71. Further, the axial length t of the balancer cover 72 needs to be at least longer than the rotation locus of the side surface of the balancer 71.
  • the axial dimension of the frame 2 is shorter than the axial dimension of the eccentric portion 61, and the balancer 71 is arranged below the frame 2 on the side surface of the eccentric portion 61. It is configured. This makes it possible to suppress the increase in size of the balancer and reduce the height of the compressor.

Abstract

Compresseur à volute comprenant : une coque qui présente des saillies sur sa surface de paroi intérieure ; une volute fixe qui comporte une plaque de base et des dents de volute et est fixée à la surface de paroi intérieure de la coque du fait que la plaque de base est supportée par les saillies ; une volute orbitale qui comporte une plaque de base et des dents de volute, présente une saillie formée sur une surface opposée à la surface sur laquelle les dents de volute sont formées, et forme une chambre de compression conjointement avec la volute fixe ; et un cadre dans lequel est disposé un arbre principal sur lequel est disposé un palier orbital supportant la saillie de la volute orbitale, un palier de butée qui comporte une partie creuse dans laquelle l'arbre principal est introduit et qui supporte de manière coulissante une surface de coulissement de la volute orbitale, et un palier principal qui supporte l'arbre principal, ledit compresseur à volute étant caractérisé en ce qu'au moins une partie du palier orbital et du palier principal sont disposées sensiblement dans le même plan dans une section transversale de compresseur à volute qui est orthogonale à l'axe central de l'arbre principal.
