GEAR WHEEL Russian patent published in 2016 - IPC F16H57/04 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in transmission gears lubricated by fictile lubricants. Gear wheel includes body, gear rim with teeth and two annular pads with outer diameter equal to gear rim tips circumference diameter, and inner diameter, which is smaller than teeth bases circumference diameter. Pads are fixed on body ends sections adjacent to gear rim, and are adjacent to teeth ends, without fixation on them. In inner surfaces of pads overlapping gear rim cavities, on sections of their adjacency to teeth side surfaces, cutouts are made located along said surfaces entire length and equidistant to them. Cutouts have rectangular shape in their cross section. Pads sections thickness located between cutouts on pads inner surfaces side is reduced by value of gap required between said surfaces and conjugated gear wheel gear rim end faces.

EFFECT: higher quality of gear wheel lubrication.
