GEAR TRAIN Russian patent published in 2017 - IPC F16H57/04 

FIELD: machine engineering.

SUBSTANCE: gear train 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 rim wheel base. The width of the element is equal to the width of the wheel body. The element is made integral with the teeth of the gear rim and connected to them by bridges oriented radially and made, respectively, of a ferromagnetic material. The area and the size of the bridges cross-section are equal over their entire height and equal to the area and size of the projection of the gear rim teeth base on the wheel body.

EFFECT: improved quality of gear wheels lubrication.
