PLAIN BEARING AND METHOD OF ITS MANUFACTURE Russian patent published in 2015 - IPC F16C17/12 F16C33/12 F16C33/18 

FIELD: wood working industry.

SUBSTANCE: plain bearing is made from compressed impregnated wood with a radial arrangement of fibres and uniform density along the whole section and contains greasing in amount 7-8% from the wood mass, and metal inclusion. The wood of the bearing contains nano-crystalline cellulose in the amount 0.5-0.8% from the wood mass, and the metal inclusion is implemented as a continuous nickel film in amount 4-6% from the wood mass with the width 0.8 mcm, covering internal surface of wood completely. The method of manufacture of the named plain bearing is also offered which comprises the manufacture of segments (4) of compressed impregnated wood with a radial arrangement of fibres and radiuses of rounding of the future bearing, application of glue, installation into auxiliary cartridge clip (1), pressing through a cone (2) with a cone angle (2), allowing to increase a density up to the value 1350 kg/m³ minimum, glue solidification and, if necessary, machining job along an internal diameter with a minimum rough tolerance.

EFFECT: improvement of quality of a plain bearing and decrease of manufacture complexity.
