ABSTRACT:
A pad-type sliding surface bearing is disclosed, in which the bearing surface is segmented into a plurality of pads that rockingly displace themselves to form a wedge shape converging in the direction of motion with a relatively moving part. The pads are each supported in a bearing housing or a support portion by a plurality of webs which indeed are integral with the pad and the housing or support portion, which allow the pad to rock by deflection of the webs. The opposing part that moves relative to the pads creates a viscous friction force in the direction to form a converging web shape between the moving part and the bearing pad, which rocks to a position until the bearing surface stabilizes where the moments of the fluid pressure and the load are in balance.
