FIELD: machine engineering.

SUBSTANCE: gearing has paired gear wheels installed by shafts in a closed housing, inside which a magnetoactive powder lubricant is placed and activated by external source of magnetic field with permanent magnet. The housing and the bodies of gear wheels are made of diamagnetic material. The teeth of the gear rims of the gear wheels are made of ferromagnetic material. There are crown wheels made of ferromagnetic material and arranged between the gear bodies and their gear rims made of ferromagnetic material are integral with the gear rims. The width of the crown wheels is less than the width of the gear wheel bodies, and the crown wheels are arranged symmetrically relative to the gear wheel ends.

EFFECT: improved quality of gear wheel lubrication quality.
