Definitions

  • the present invention relates to a co-rotating scroll compressor.
  • the co-rotating scroll compressor includes a driving-side scroll and a driven-side scroll that rotates together with and in synchronization with the driving-side scroll.
  • the co-rotating scroll compressor rotates the driving shaft and the driven shaft in the same direction at the same angular velocity by offsetting a driven shaft that supports the rotation of the driven-side scroll from a driving shaft that rotates the driving-side scroll by the turning radius.
  • the present invention has been made in view of the situation as above, and an object thereof is to provide a co-rotating scroll compressor that can be downsized.
  • a co-rotating scroll compressor of the present invention employs the following solutions.
  • a co-rotating scroll compressor includes: a driving-side scroll member driven by a drive unit so as to rotate, and including a plurality of spiral driving-side walls provided about a center of a driving-side end plate at predetermined angular intervals and in a number corresponding to the driving-side walls, the driven-side walls being engaged with the corresponding driving-side walls so as to form a compression space; a synchronous driving mechanism that transmits driving force from the driving-side scroll member to the driven-side scroll member so that the driving-side scroll member and the driven-side scroll member rotationally move in a same direction at a same angular velocity; and a housing comprising a motor accommodation part that accommodates a motor for rotating the driving-side scroll member, and a scroll accommodation portion that accommodates the scroll members and the synchronous driving mechanism, in which the housing includes: partition surfaces partitioned at a plane including the scroll members and orthogonal to rotational axes of the scroll members; and fasten
  • the driving-side walls arranged about the center of the end plate of the driving-side scroll member at predetermined angular intervals and the corresponding driven-side walls of the driven-side scroll member are engaged with each other.
  • a plurality of pairs each formed by one driving-side wall and one driven-side are provided, and the scroll-type compressor including a plurality of lines of walls is formed.
  • the driving-side scroll member is driven by the drive unit so as to rotate, and the driving force transmitted to the driving-side scroll member is transmitted to the driven-side scroll member via the synchronous driving mechanism.
  • the driven-side scroll member rotationally moves in the same direction at the same angular velocity as the driving-side scroll member while rotating.
  • the double rotating-type scroll-type compressor in which both of the driving-side scroll member and the driven-side scroll member rotate is provided.
  • the housing that accommodates both of the scroll members and the synchronous driving mechanism is included.

Therefore, when both of the scroll members are seen from the rotational axis, the projected shape of both of the scroll members becomes an elliptical shape having the major axis in the direction in which the rotational axes are connected to each other. Therefore, a space is formed in the region on the periphery of both of the scroll members and on the lateral side when seen from the straight line connecting the rotational axes of both of the scroll members.

  • a predetermined space can be secured between the outer peripheral side of the driving-side bearing and the driven-side bearing and the external form of the housing.
  • mounting holes for performing mounting on an external structure such as an engine, for example are formed.
  • the mounting holes can be formed without upsizing the external form of the housing, and hence the co-rotating scroll compressor can be configured in a compact manner.
  • the mounting holes are typically used as holes for attaching mounting feet for performing mounting on the external structure.
  • the mounting holes may be through holes or bottomed holes.
  • the fastening portions are provided in the space formed in the region on the periphery of both of the scroll members and on the lateral side when seen from the straight line connecting the rotational axes of both of the scroll members to each other, and hence the external form of the housing can be caused to be as small as possible, and the co-rotating scroll compressor can be configured in a compact manner.
