PLAIN THRUST BEARING FROM SYNTHETIC RESIN Russian patent published in 2013 - IPC F16C17/04 F16C33/10 C10M107/50 F16F9/54 B60G15/06 

FIELD: machine building.

SUBSTANCE: plain thrust bearing from synthetic resin has upper housing (100) from synthetic resin, lower housing (200) from synthetic resin and assembly (300) of thrust bearing from synthetic resin, which is placed between housings (100) and (200). At boundaries of a sliding strip between upper surface of lower annular plate-like section (202) of housing (200), which restricts the lower surface of lower annular groove (204) and lower surface of upper annular plate-like section (102) of housing (100) on one side, and upper surface and lower surface of assembly (300) on the other side, which come into sliding contact with upper and lower surfaces, there is silicon grease based on silicon oil and having kinematic viscosity coefficient at 25°C of not less than 0.0001 m²/s and not more than 0.5 m²/s and containing a thickener to maintain working penetration of not less than 200 and not more than 400. The above silicon oil is silicon oil that contains an additive or modified silicon oil.

EFFECT: creation of plain thrust bearing that is capable of preserving low friction coefficient and preventing microslipping phenomenon at sliding during a long period of time, which allows preventing abnormal friction noise referred to microslipping phenomenon.
