LUBRICATING DEVICE OF TOOTH-WHEEL Russian patent published in 2015 - IPC F16H57/04 

FIELD: machine building.

SUBSTANCE: lubricating device contains pair of lubricant returning plates installed fixedly relatively to the rotating tooth-wheel at both end faces of the toothed rim perpendicular to them. The lubricant returning plates overlap the teeth height and are oriented in radial plane of the lubricated tooth-wheel. The lubricant returning plates have spacing below width of the toothed rim, and are secured on the gear casing by their sides removed from the toothed rim, also in them at the toothed rim side the cuts are made perpendicular to its end faces. The device contains additional pair of similar lubricant returning plates installed with displacement in the rotation plane of the lubricated tooth-wheel from the first pair, and in which the cuts are made with displacement in radial plane of the lubricated tooth-wheel relatively to the cuts in the first pair by pitch equal to half of pitch of the cuts in the first pair.

EFFECT: higher efficiency of lubrication.
