SYSTEM FOR COMPACTION OF NON-GREASED HINGE JOINTS Russian patent published in 2020 - IPC E02F9/00 F16C11/04 F16C33/74 F16J15/16 

FIELD: machine building.

SUBSTANCE: present invention generally relates to a hinge joint for mechanical equipment. In particular, the present invention relates to the hinge joint sealing systems for mechanical equipment, for example, construction equipment, excavator ground engaging tool, etc. Pivoted coupling (300, 400) of machine comprises structural element (302), in which hole (304) for pivot is made; bearing seat (306), in which bearing hole (308) is made; self-lubricating bearing (310), in which hole (312) for the kingpin is made; kingpin (314), which is located in holes (304, 312) of bearing (310) and structural element (302); and sealing assembly (100, 200), which is located in bearing bore (308) for bearing seat (306). Seal assembly (100, 200) comprises radially outer non-deformable element (102); radially internal non-deformable element (104); and element (106, 202) from microporous foam material, which is located between radially inner and radially external non-deformable elements (102, 104) and is coaxially aligned with them.

EFFECT: more perfect sealing system for self-lubricating bearings in movable hinged joint of mechanical equipment.
