BALL BEARING OF TRANSPORT VEHICLE Russian patent published in 2012 - IPC F16C11/06 

FIELD: machine building.

SUBSTANCE: ball bearing of transport vehicle includes housing (3), pin (1) with ball head (2), insert (4) located between ball head (2) and housing (3); at that, lubrication is located on head (2) surface. Ball head (2) on its surface includes two areas (5;6) and hardness of area (6) is less than hardness of area (5). Area (6) with smaller hardness is located on pole surface of ball head (2) and/or on middle surface of ball head (2). Pin (1) with ball head (2) has the possibility of being rotated relative to longitudinal axis of pin (1) at deviated angular position of pin (1) relative to longitudinal axis of ball bearing.

EFFECT: more uniform distribution of load from ball head to insert and housing of bearing during bearing operation at action of axial loads on the pin, due to which service life of ball bearing of transport vehicle increases.
