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

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to machine parts, and can be used in machines shafts and machines support units. Sliding bearing contains anti-friction liner in the form of helical spiral from thread (4) installed on the shaft trunnion (1), which turns are closely adjoin each other along the trunnion (1) entire length and by their ends fixed at the trunnion (1) ends. Thread cross section has the form of a figure made up of a rectangle (ab, bc, cd, da), adjacent to the trunnion (1) with one side (ab), and equilateral trapezium (which basis is eƒ, vertex is gƒ, sides are ƒg and he). Base (eƒ) is equivalent to the rectangle side (ab) and adjoins the rectangle opposite side (cd). Free space between the spiral adjacent turns sides is completely filled with solid lubricant (5).

EFFECT: increase in the bearing operation reliability.
