TOOTH REDUCER Russian patent published in 2017 - IPC F16H57/04 

FIELD: machine engineering.

SUBSTANCE: invention relates to machine engineering, in particular to the machine parts. A tooth reducer contains a closed casing with stiffeners located therein and an oil bath with a liquid lubricant, in which the downstream tooth-wheel of the tooth wheel gear is immersed. A pair of baffles in the form of the flat rectangular plates, fixed on the bottom of the tooth reducer casing and overlapping a part of the downstream tooth-wheel immersed in the oil bath, is located along the both ends of the downstream tooth-wheel, parallel to them and with the gaps agaist them. Along the both lateral casing walls with the stiffeners there is a pair of vertical profile plates mounted on these stiffeners and on the casing bottom and smoothly envelopping the edges of the stiffeners by fitting the casing corners adjacent to these walls. The through windows are made in the lower parts of the profile plates. The height of the stiffeners and the vertical profile plates is above the upper level of the oil bath.

EFFECT: improving lubrication quality of the gear elements is achieved.
