Co-rotating scroll compressor

Abstract

A co-rotating scroll compressor includes a driving-side scroll member, a driven-side scroll member, and a housing that accommodates both of the scroll members. The housing includes partition surfaces partitioned at a plane including both of the scroll members and approximately orthogonal to rotational axes of the scroll members, and flange parts that fasten the partition surfaces in a region on a periphery of the scroll members and on a lateral side when seen from a straight line connecting the rotational axes of the scroll members to each other.

1 . A co-rotating scroll compressor, comprising:
 a driving-side scroll member driven by a drive unit so as to rotate, and comprising a plurality of spiral driving-side walls provided about a center of a driving-side end plate at predetermined angular intervals;   a driven-side scroll member comprising spiral driven-side walls, the driven-side walls being provided about a center of a driven-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 that accommodates the scroll members and the synchronous driving mechanism,   wherein the housing comprises:
 partition surfaces partitioned at a plane comprising the scroll members and approximately orthogonal to rotational axes of the scroll members; and 
 fastening portions that fasten the partition surfaces in a region on a periphery of the scroll members and on a lateral side when seen from a straight line connecting the rotational axes of the scroll members to each other. 
   
     
     
         2 . The co-rotating scroll compressor according to  claim 1 , wherein the fastening portions are provided in a region approximately orthogonal to the straight line connecting the rotational axes of the scroll members to each other. 
     
     
         3 . The co-rotating scroll compressor according to  claim 1 , wherein the fastening portions are provided on an inner side with respect to a circumscribed circle surrounding the driving-side scroll member and the driven-side scroll member. 
     
     
         4 . The co-rotating scroll compressor according to claim  1 , further comprising:
 a driving-side bearing supporting rotation of the driving-side scroll member; and   a driven-side bearing supporting rotation of the driven-side scroll member,   wherein a mounting hole for performing mounting on an external structure is formed on an outer peripheral side of the driving-side bearing and/or the driven-side bearing.
