SLIDING BEARING Russian patent published in 2018 - IPC F16C17/00 F16C33/04 F16C33/26 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, in particular to machine parts, and can be used in bearing units of shafts and axes of mechanisms and machines. Sliding bearing has antifriction liner in the form of helical spiral made of the round cross section thread, secured on the journal surface and fixed on it with its ends, installed in the support housing (3) on the trunnion (1) with the shaft (2) length (L). Spiral is made of two parts (with each length of l). These parts threads (4 and 5) turns direction is opposite, directed towards the trunnion center. By the trunnion ends are sections of the shaft, and between the spiral two parts, the trunnion, the broadenings (6, 7, 8) is set, which diameters are greater than the trunnion diameter, these broadenings surfaces facing the coil turns are made with inclination (at an angle of α) relative to the axis and are closely adjacent to these turns.

EFFECT: optimization of the sliding bearing design and increase in its operation reliability.
