TAPER PLAIN BEARING Russian patent published in 2008 - IPC F16C21/00 

FIELD: mechanics.

SUBSTANCE: invention relates to machine building and can be used in most industries for production of machine and mechanism shaft bearing supports operated under axial and radial loads. The taper hydro-static-and-dynamic taper-thrust surface plain bearing incorporates the shaft journal external bush with grooves on its inner surfaces. One of the said grooves, representing a circular groove, is arranged across the bearing taper generating lines and shifted relative the bearing central transverse axis towards the taper smaller base by 0.25 to 0.35 of its length. Note that working fluid is forced via the radial hole into the aforesaid groove. The bearing inner surface facing the larger base opposite the said circular groove is furnished with lengthwise recesses to form a multi-wedge inner surface of the bearing. The proposed taper plain bearing feature consisting in separating and duplicating the bearing smooth and multi-wedge functions serves to simplify its design and operation.

EFFECT: higher reliability and longer life, ease of manufacture and operation.
