Embodiment Construction

[0008] Such as figure 1 As shown, the non-revolving scroll 1 is installed on the support body 3, and the first spiral scroll 1-2 protrudes downward from the end plate 1-1, and 1-3 is the hub of the non-revolving scroll 1. The second spiral wrap 2-1 protruding upward from the end plate 2-3 of the scroll member 2 intersects with the first spiral wrap 1-2 to form a plurality of moving fluid chambers. At the central position of the end plate 2-3 of the orbiting scroll 2, there is a hub 2-2 embedded in the cavity of the non-orbiting scroll upwards, and the outer circular wall of the hub 2-2 is perpendicular to the end plate of the orbiting scroll 2 The height of the plane where 2-3 is located is smaller than the height of the second spiral scroll 2-1.

[0009] Such as figure 2 As shown, the projection of the hub 2-2 in the horizontal direction is a spiral, where the BB' arc is the projection of the starting end of the hub in the horizontal direction, the B'C arc is the projectio...

Abstract

A hub embedded vortex compressor is disclosed. The second spiral vortex circles extended from end plate is mutually inserted with the first ones on the non-revolving vortex part. The revolving vortexpart is driven by crankshaft to revolve relatively to the non-revolving one. A rotation preventer is composed of said revolving vortex part and cross coupling. A hub integrated with the second spiralvortex circle is embedded in the cavity of non-revolving vortex part. It can greatly decrease the tilt force moment generated by acting on the fluid in working cavity, so improving the stress condition of bearing on crankshaft and sealing condition of end face.

Description

technical field [0001] The invention is a scroll compressor with a new structure. Background technique [0002] The prior art is the Chinese patent "Anti-rotation Mechanism of Scroll Compressor", Patent No.: 95119401.1. In the prior art, the crankshaft is rotatably supported by bearings, and the orbiting scroll is driven to perform orbital motion relative to the non-orbiting scroll, and the hub is located under the end plate of the orbiting scroll. This structure causes the gas in the fluid working chamber to generate a large dumping moment, the force on the scroll is uneven, the sealing state is not good, and the eccentric wear between the scroll working surfaces is relatively large. [0003] The purpose of the present invention is to adopt the structure embedded in the hub to reduce the above-mentioned dumping moment, to make the force on the scroll wrap uniform, and to reduce the eccentric wear between the scroll wrap working surfaces. Contents of the invention [000...
