TOOTH-WHEEL LUBRICATING DEVICE Russian patent published in 2017 - IPC F16H57/04 

FIELD: machine engineering.

SUBSTANCE: invention relates to machine engineering and can be used in the tooth-wheel gears, the tooth-wheels of which are lubricated with plastic lubricants. A lubricating device contains a pair of annular linings reinforced on the wheel body ends with the gaps against the ends of the teeth ring. There is a flat plate in each gap, the surfaces of which are parallel to the wheel plane. The plates are located symmetrically against each other. The plates are rigidly reinforced on the base, which is stationary against the rotating wheel, with their upper section placed above the tooth ring vertices. The plates fill the gaps around their radial cross section with the possibility of the free wheel rotation against the plates. The ends of the plates, facing the center of the wheel, are equidistant from the circles of the annular lining internal surfaces to which they are directed. The ends of the plates along the top of the teeth ring, are oriented radially against the wheel. The ends located at the side of the climbing teeth during the wheel rotation, are bevelled towards the ends of the tooth ring. And the size of the plates in the wheel rotation plane is set with the possibility of simultaneous overlapping of at least two ends of the teeth by them.

EFFECT: improving quality of the tooth-wheel lubrication is provided.
