GEAR LUBRICATING DEVICE Russian patent published in 2016 - IPC F16H57/04 

FIELD: machine building.

SUBSTANCE: invention can be used in reverse tooth gears with crankcase lubrication. Lubricating device of gearing contains lubricant supplying element in form of impeller with blades installed on shaft articulated with rotating gearing elements. Blade wheel lower part is immersed in oil bath with top level, located in gearing housing. Impeller is located under lubricated elements. Impeller is equipped with segment-like casing formed by two vertical flat walls and circular surface. Casing is installed on gearing housing fixedly relatively to rotating wheel, symmetrically relative to vertical. Casing covers lower part of wheel immersed in oil bath, and is arranged with exceedance of height of upper level bath. In lower part of each vertical flat wall of casing with abutment to its peripheral surface, there is filling hole, symmetrical to casing vertical line. On sections of flat side walls of casing, dipped in oil bath are radially oriented cuts along whole length with wings arranged relative to vertical axis of symmetry of casing on side cutouts opposite to this axis of symmetry.

EFFECT: expanded functional capabilities of lubricating device.
