Please in conjunction with Fig. 1 referring to Fig. 2 and shown in Figure 3, prior art scroll compressor radial compliance compensation mechanism adopts the form that excentric sleeve 5 is set at bearing 4 places, on excentric sleeve 5, all adopt cylindrical body 51, on cylindrical body 51, give prominence to the structural type of cylindrical convex body 511 prejudicially, as shown in Figure 3.Though the structural type of this eccentric protruding-type can realize predetermined function preferably, even moving vortex circle 2 outer wall energys are close to quiet vortex ring 1 inwall, and make the radial compliance compensation mechanism have the yielding effect, still, but it has increased the difficulty of processing in the scroll compressor production process and the raising of cost.
Summary of the invention
The purpose of this utility model is to provide a kind of improved scroll compressor radial compliance compensation mechanism, and it can reduce difficulty of processing and cost in the scroll compressor production process effectively.
The purpose of this utility model is achieved in that
A kind of scroll compressor radial compliance compensation mechanism comprises: a quiet vortex ring; One moving vortex circle, the outer wall of this moving vortex circle and the inwall of quiet vortex ring are close together; All active chambers, these active chambers are formed in conjunction with the back by quiet vortex ring and moving vortex circle; Be arranged on the bearing of the outer middle side part of moving vortex circle; Be arranged in the excentric sleeve of bearing; Be arranged on the cylindrical body in the excentric sleeve, side at cylindrical body is provided with an eccentric pivot hole, on eccentric pivot hole in conjunction with an eccentric shaft, be characterized in: a cover body opening is set in described cylindrical body, one circular entire body assembly is set in this cover body opening, and this circle entire body assembly and cover body opening tight connecting are together.
In above-mentioned scroll compressor radial compliance compensation mechanism, wherein, described circular entire body assembly comprises, one is embedded in circular entire body in the cylindrical body body hole, closely is arranged on straight pin in the circular entire body.
In above-mentioned scroll compressor radial compliance compensation mechanism, wherein, described cover body opening is arranged on the cylindrical body prejudicially, and circular entire body assembly also is arranged on the cylindrical body prejudicially.
The utility model scroll compressor radial compliance compensation mechanism makes it compared with prior art owing to adopted technique scheme, has following advantage and good effect:
1. the utility model is owing to adopt the circular entire body assembly of inlaying circular entire body in the cylindrical body prejudicially and forming with the straight pin that circular entire body is combined closely, therefore the radial compliance compensate function of the scroll compressor that can realize easily on excentric sleeve;
2. the utility model is inlayed circular entire body assembly prejudicially owing to adopting in the cylindrical body, and is therefore not only easy to process, and can reduce manufacture cost and cost of material well;
3. the utility model is because the outer wall energy of moving vortex circle is close to quiet vortex ring inwall, therefore can guarantee the sealing of all active chambers in the compressor, and, when having oil or liquid refrigerant or solid particle in the active chamber, moving vortex circle can and appoint them by sealing surface to the center yielding, thereby can not damage compressor.

Embodiment
See also shown in Figure 1ly, Fig. 1 is the structural representation of scroll compressor radial compliance compensation mechanism.The utility model scroll compressor radial compliance compensation mechanism comprises, a quiet vortex ring 1; With the moving vortex circle 2 that quiet vortex ring 1 makes up in opposite directions, the inwall of the outer wall of this moving vortex circle 2 and quiet vortex ring 1 is close together; This quiet vortex ring 1 forms a plurality of active chambers 3 with moving vortex circle 2 combination backs; Middle side part is provided with a bearing 4 outside moving vortex circle 2; Be arranged in the excentric sleeve 5 of bearing 4; One cylindrical body 51 is set in excentric sleeve 5, an eccentric pivot hole 512 is set in a side of cylindrical body 51, on eccentric pivot hole 512 in conjunction with an eccentric shaft 6.
Please in conjunction with Fig. 1 referring to Fig. 4 to shown in Figure 6, Fig. 4 to Fig. 6 is respectively straight pin and the structural representation of circular entire body assembly and the overall structure schematic representation of excentric sleeve in the sectional structure schematic representation, excentric sleeve of excentric sleeve in the scroll compressor radial compliance compensation mechanism.
The utility model scroll compressor radial compliance compensation mechanism unlike the prior art be, one cover body opening, 511 (see figure 4)s are set in cylindrical body 51, this cover body opening 511 is to be arranged on prejudicially on the cylindrical body 51, one circular entire body assembly 52 (seeing Fig. 4 and Fig. 5) is set in the cover body opening 511 of off-centre setting, this circle entire body assembly 52 comprises, an one circular entire body 52 1 and a straight pin 522, this circle entire body 521 is embedded in cylindrical body 51 overlaps in the body openings 511, and straight pin 522 closely is arranged in the circular entire body 521, thereby make circular entire body assembly 52 and cover body opening 511 tight connectings together, and also be and be arranged on prejudicially on the cylindrical body 51.
