GEAR TRANSMISSION Russian patent published in 2018 - IPC F16H57/04 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering and can be used in gears lubricated by magnetic particle method. Gear train comprises paired gears mounted by means of shafts in a closed housing within which a magnetically active powdered lubricant is activated, which is activated by an externally located magnetic field source. Body and bodies of gears are made of diamagnetic material. Teeth of gear wheels of gears are made of ferromagnetic material. Between the bodies of cogwheels and their gear rims are crowned cogwheels made of ferromagnetic material, in conjunction with serrated crowns, the width of which is equal to the width of the gear rims. At the ends of the body of each gear wheel, a pair of annular linings made of a diamagnetic material, the outer diameter of which is not less than the diameter of the circumference of the bases of the gear rim of this wheel, and their width is not less than the thickness of the crown wheel.

EFFECT: quality of the lubrication process of the gear wheel is improved.
