Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

[0011] Such as figure 1 The scroll compressor shown is fixed with a fixed scroll 1 in the casing, and the fixed scroll 1 meshes with the scroll wall of the movable scroll 2 through the scroll wall on it, and the movable scroll 2 as figure 1 The needle row 3 of the needle roller bearing is installed in the bearing hole of the lower end surface as shown, and the shaft sleeve 4 of the balance assembly is set in the needle row 3, and the eccentric crank of the drive shaft 5 is installed in the through hole of the shaft sleeve 4, and the shaft Set of 4 in figure 1 The outer surface of the shown lower end is a hexagonal prism surface surrounded by six planes, and the hexagonal prism surface is joined with the inner hole of the hexagonal prism surface of the balance weight 6, as figure 2 , image 3 shown. Since the joint surface between the outer side of...

Abstract

The invention discloses a scroll compressor, relating to the technical field of fluid machinery. The scroll compressor comprises a balancing component installed on a driving shaft, wherein the balancing component is provided with a shaft sleeve and a balancing weight installed outside the shaft sleeve, and at least part of the binding surface between the outer side of the shaft sleeve and the balancing weight is the plane for preventing the relative rotation between the shaft sleeve and the balancing weight. Compared with the prior art, the invention can solve the problem that low working reliability of the balancing component can damage the machine.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, in particular to a scroll compressor whose driving shaft of a movable scroll is equipped with a balancing assembly. Background technique [0002] The core components of the scroll compressor include a moving scroll and a fixed scroll. When the two scrolls move relative to each other, the movement of the scroll wall engagement parts of the two scrolls shrinks the space enclosed in the two scrolls. The volume of the gas medium in each scroll is used to achieve compression, and finally the compressed gas medium is discharged. The fixed scroll of the scroll compressor with this structure is often fixed on the fuselage, and the movable scroll is driven by the eccentric drive shaft to rotate relative to the fixed scroll. In order to reduce the impact of this eccentric drive To rotate, a balance assembly needs to be set on the drive shaft. In the prior art, this balance assembly includes a sha...
