GEAR BOX Russian patent published in 2017 - IPC F16H57/04 

FIELD: machine engineering.

SUBSTANCE: gear box contains a closed casing with stiffeners located therein and an oil bath with a liquid lubricant, in which the downstream tooth-weel of the tooth weel gear is immersed. In the lower-lying gear and the bottom of the body, parallel to the bottom, it is U-shaped groove oriented in the plane of rotation of the downstream gear. The length of the troughs less than the length of a gear reducer casing, and the chute in the plane overlaps stiffener casing and the downstream portion of the gear is immersed in an oil bath. Between the bottom of the chute and downstream gear, and the gaps formed between the bottom of the trough and the bottom of the reduction gear housing. Upper trough wall situated above the upper level of the lubricating oil bath material. Between the walls of the trough and the ends of the transmission gears formed gaps, and mounted on a wall of the trough stiffeners reduction gear housing.

EFFECT: increased quality of the gearing lubrication.
