Gear train lubricating device

摘要

A lubricating device for a gear train (5) including a plurality of gears meshing with each other includes a shroud (7) configured to cover the gear train (5) and a housing (9) configured to cover the shroud (7). The shroud (7) includes: an oil supply nozzle (25) configured to supply oil (OL) to a meshing position (21) of the gear train (5); and oil-drain ports (41) through which the oil (OL) is discharged from the shroud. The housing (9) includes, at its lower part, a draw-out port (43) through which the oil (OL) discharged from the oil-drain ports (41) is drawn to the outside of the housing. Guide members (47) are provided between the shroud (7) and the housing (9). The guide members (47) guide the oil (OL) discharged from the respective oil-drain ports (41) of the shroud (7) such that the oil (OL) flows downward through space (S) between the shroud (7) and the housing (9).

主权项

1. A gear train lubricating device comprising:
a shroud covering a gear train including a plurality of gears meshing with each other, the shroud including an outer peripheral wall covering the gear train from radially outward, side walls covering both respective side faces of the gear train, and an oil supply nozzle configured to supply oil to a meshing position of the gear train and including oil-drain ports through which the oil is discharged from the shroud; a housing configured to cover the shroud, the housing including at its lower part in a gravitational direction, a draw-out port through which the oil discharged from the oil-drain ports is drawn to outside of the housing; and guide members provided between the shroud and the housing and configured to guide the oil discharged from the respective oil-drain ports of the shroud such that the oil flows downward in the gravitational direction through space between the shroud and the housing, wherein each of the guide members has at least one end of an axial direction which contact with or adjacent to an inner wall surface of the housing, and at least one portion of a guide face of each of the guide members is opposed to and non-parallel to flow directions of the oil discharged from the oil-drain port to the outside of the shroud to redirect the flow of the oil away from the shroud.
