FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly to machine parts, and can be used in gear transmissions arranged in closed bodies - gear boxes with crankcase lubrication. Gear box contains an oil bath with liquid lubricating material, in which the downstream transmission gear wheel is immersed. Pair of vertical shaped plates is fixed along the both ends of this gear wheel parallel to them with gaps relative to bottom of the oil bath on stiffness ribs. Pair of vertically oriented shaped plates, wave-shaped in a plan is fixed in the oil bath with gaps relative to its bottom and with its upper level surpassing on stiffness ribs. Ridges of wave-shaped plates are arranged on stiffening ribs with smooth rounding of them. Recesses of wave-shaped plates are faced to walls of the body between stiffness ribs.

EFFECT: quality increase of lubricating gear transmission elements is obtained.
