SUPPORT RING ASSEMBLY AND ITS FABRICATION Russian patent published in 2014 - IPC F16C27/06 F16C33/28 

FIELD: machine building.

SUBSTANCE: invention relates to support rings arranged between moving parts, particularly, to support rings with functional layers. Proposed assembly comprises outer component (53), inner component (55) arranged therein to displace relative thereto and support ring (61) arranged between the components (53, 55). Ring (61) comprises circular strip (63) made of metal, radial inner surface and outer surface. Said metal material represents a perforated sheet while sheep profile includes waves, cones and spherical structures. Additionally, ring (61) comprises material (71) with low friction factor to envelop strip (63) so that both inner and outer radial surfaces are located, in fact, inside material (71). Invention covers also the method of fabrication of said ring (61) that includes the steps that follow: (a) application of sheet made of metal material; (b) perforating the sheet; (c) making of the sheet geometrical structures to shape the sheet profile; (d) fitting of said profile in material (71) with low friction factor; (e) shaping said sheet to ring (61).

EFFECT: lower retention and friction factor, decreased noise and vibration.
