PLAIN THRUST BEARING FROM ARTIFICIAL RESIN Russian patent published in 2012 - IPC F16C17/04 F16C33/20 B60G15/06 

FIELD: mechanics.

SUBSTANCE: invention relates to a plain thrust bearing from synthetic resin, in particular, for thrust bearing suspension rack-type four-wheeled vehicle. The bearing has an upper housing (100), comprising an radial flat spot (102), lower body (200) superimposed on the body (100) with possibility of rotation around the axis of the housing (100) and contains an radial flat spot (202), opposite the site (102 ), and an radial groove (204), performed at the site (202), which is surrounded by the first (203) and second (205) concentric radial projection housing (200). The bearing assembly also includes a node of (300) plain thrust bearing made of disc (304), which is placed in the radial groove (204), is a sliding contact with an radial flat spot (102) and has a circular hole (101), done in the central part . At the same node (300) mounted in an radial groove (204) with an radial gap (AI) between the inner peripheral surface (301) round hole (302) and the outer peripheral surface (207) of the first projection (203) and the radial gap (A2) between the outer peripheral surface (303) disk (304) and an inner peripheral surface (208) of the second projection (205). Node (300) is located in a groove (204) so that its upper surface (305) protrudes from the grooves opening (204) so as to enter into contact slider with the bottom surface (105) housing (100), and its lower surface (306) is in contact slider with the bottom surface (209) groove (204). Housing (100) is combined with the housing (200) by the elastic landing on the housing (200). The sum (A) of the volume of radial gaps (AI) and (A2) is less than the amount (B) of the node part (300), which protrudes from the hole of the groove (204).

EFFECT: time preservation of slipping characteristics such as low coefficient of friction and wear resistance.
