GEARING Russian patent published in 2017 - IPC F16H57/04 

FIELD: machine engineering.

SUBSTANCE: gearing contains the sealed housing with gears installed in it, made of the ferromagnetic material and powder magnetically active lubricant, activated by the magnetic field. There is the fixed pair of linings in the form of disks on the end surfaces of each wheel, made of magnetically passive material, such as plastic. The outer perimeters of the linings are in the shape of a circle radius equal to the radius of the circle the vertices of the ring gear. In the centers of the linings are made through holes, with not smaller radius than planting hole rims radius. In the lining, in the areas of their contiguity to the bottom of trenches ring gear are made through holes, bottom which coincides with a circumference of depressions ring gear, and their sides coincide with the lateral surfaces of the teeth.

EFFECT: lubrication process quality improve.
