OIL CHUTE AND TRANSMISSION (EMBODIMENTS) CONTAINING OIL CHUTE Russian patent published in 2019 - IPC F16H57/04 B60K17/16 

FIELD: machine building.

SUBSTANCE: invention relates to transmission oil flue. Section (30) of oil chute (20) is divided into first section (42) and second section (52) by means of partition wall (36). Inclined section (44a), which is inclined upwards in direction from separating partition (36), is formed on lower surface (44) of first section (42). Lower surface (58) of second section (52) is formed for inclination downwards in direction of through hole (38) side. Lubricating oil scooped up by ring gear (9) collides with separating partition (36) and is directed to the side of through hole (37) for introduction into the duct section. On the other hand, the lubricating oil that passes beyond partition wall (36) is introduced into the second insertion portion (52) for insertion into the flow passage from through hole (38). Flow of lubricating oil tending to flow back is restrained by means of inclined section (44a), and flow of lubricating oil towards through hole (37 and 38) is facilitated by inclined upward section (44a) and bottom-inclined bottom surface (58).

EFFECT: improved lubrication is achieved.
