It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1, the first embodiment of the present invention provides a movable disk assembly, which includes a movable disk, the movable disk includes: a base body 10; a scroll 20 disposed on one side surface of the base 10; and the annular flange structure 30 is arranged on the outer peripheral surface of the base body 10 in a surrounding mode, and the outer diameter of the annular flange structure 30 is larger than that of the base body 10.
In recent studies on mechanical frictional vibration and frictional noise, the applicant found that frictional noise is approximately inversely proportional to the frictional contact area, which suggests that we should increase the contact area between the friction pair by a suitable amount in order to reduce the mechanical (frictional) noise. From the above findings, the above-mentioned movable plate assembly has been proposed based on the principle of increasing the contact area of the friction pair to reduce the mechanical friction noise.
Adopt this scheme, through set up annular flange structure 30 at the outer peripheral face of base member 10, compare with original driving disk, increased the radial dimension of driving disk to can increase the area of contact of the wear pad in driving disk and the compressor or the friction area of the support in driving disk and the compressor, and increase area of contact can reach the effect that reduces the friction noise, thereby can reduce the noise of compressor.
In the present embodiment, the base 10, the scroll 20, and the annular flange structure 30 are formed as a single body, which can improve structural strength and reduce cost.

With this solution, the annular flange structure 30 is not in direct contact with the wear plate or carrier, but is in contact with the wear plate or carrier through the self-lubricating annular member 40. Therefore, not only can the friction power consumption between the movable disc and the wear-resisting plate or the bracket be reduced, but also the friction noise between the movable disc and the wear-resisting plate can be further reduced. The self-lubricating ring member 40 may be bonded to the annular flange structure 30.
In the present embodiment, the annular flange structure 30 has an annular groove 31, and the self-lubricating annular member 40 includes an annular plate 41 and a retainer ring 42 provided projecting on one side of the annular plate 41, the retainer ring 42 being located in the annular groove 31, and the annular plate 41 and the end surface of the self-lubricating annular member 40 being engaged. Through the arrangement, the positioning and the limiting of the annular flange structure 30 and the self-lubricating annular piece 40 can be facilitated, and the connection reliability is improved. The stop ring 42 of the self-lubricating ring member 40 may be disposed in an embedded manner within the annular groove 31.
In particular, the self-lubricating annular element 40 is made of polytetrafluoroethylene. Alternatively, the self-lubricating annular member 40 may be made of other materials having self-lubricating properties.
As shown in fig. 6, in the third embodiment, unlike the above-mentioned embodiments, the movable plate assembly further includes: a bracket 50; the wear-resisting piece 60, the wear-resisting piece 60 is located between support 50 and the movable disc. The bracket 50 supports the moving plate. The wear-resisting plate 60 is arranged to avoid the direct contact between the bracket 50 and the movable disc, so that the wear is reduced. With this arrangement, the contact area with the wear pad 60 can be increased by the annular flange structure 30 in the moving disk, so that noise due to friction can be reduced.
