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

FIELD: machine engineering.

SUBSTANCE: toothed gear comprises pair toothed wheels mounted on shafts installed by bearings in a closed body with a magnetically active powdered lubricant placed in it and activated by the magnetic field. The toothed wheels, shafts and bearings are made of ferromagnetic material, and the body is made of diamagnetic material. At the end of each toothed wheels a pair of annular plates of diamagnetic material, the internal diameters of which are equal to the diameters of the shafts, on which these wheels are mounted, the external diameters of the annular plates are not less than the diameter of the circumferences of the bases of the gear rims of these wheels. The mounting bores of the bearings from the inside of the body are covered with diamagnetic material plates rigidly fixed to the gear body, with gaps relative to the ends of the bearings and with central holes for the shafts. Between the annular plates on the wheels and the plates on the body tubular plates of diamagnetic material are located, the internal diameters of which are equal to the diameters of the shafts, rigidly fixed on the shafts and the annular plates of the wheels and adjacent to the bearing plates with the possibility of free rotation with respect to them.

EFFECT: increase the quality of toothed gear lubrication.
