GEARING Russian patent published in 2017 - IPC F16H57/04 

FIELD: machine engineering.

SUBSTANCE: gearing comprises paired gear wheels fixed on shafts mounted in a closed body with a magneto-active powdered lubricant arranged therein which is activated by an externally located source of a magnetic field. The body is made of diamagnetic material, the teeth of the gear rims of the wheels are made of ferromagnetic material. The body of each gear wheel is made of diamagnetic material. A tubular element made of ferromagnetic material is embedded in the body of each gear wheel. The outer diameter of the element is less than the diameter of the circumference of the gear wheel base. The width of the element is less than the body thickness. The element is made integral with the teeth of the gear rim and is connected to them by radially oriented bridges made of ferromagnetic material. The area and dimensions of the bridges are equal throughout their height. The width of the bridges equals the width of the tubular element, and the thickness of the bridges equals the size of the projection of the teeth base thickness on the wheel body.

EFFECT: increase quality of gearing lubrication process.
