FIELD: machine building. ^ SUBSTANCE: invention refers to self-lubricating rotary joint for interconnection of lines. The connection consists of a case, internal surfaces of which form a cavity, and of an enveloped element including a body and a flange. The element is inserted into the cavity so, that the flange rests on internal surfaces. Further, the connection consists of a nut secured in the cavity of the case. In axial direction the nut rests on internal axial lug on the flange of the enveloped element. The nut surrounds the body of the enveloped element and facilitates its rotation. Liquid leaks between the elements lubricating the connection. Lines are connected to the channels and are interconnected and rotate without ball or needle bearings. ^ EFFECT: extensive surface contact and reliable support between flange and body of enveloped element and nut allowing to sustain and distribute forces. ^ 37 cl, 23 dwg |
