Abstract
Systems are provided for an integrated oil shroud and pump oil pickup. In some examples, an assembly may include an oil shroud element configured to enclose a lower portion of at least one rotating gear of a gearbox, and an oil intake element with an oil filter and an oil outlet configured to couple to a pump of an oil recirculating circuit, where the oil intake element is in face-sharing contact with the oil shroud element.
Claims20
An assembly comprising:
- an oil shroud element configured to enclose a lower portion of at least one rotating gear of a gearbox;
- and
- an oil intake element with an oil filter and an oil outlet configured to couple to a pump of an oil recirculating circuit, wherein the oil intake element is in face-sharing contact with the oil shroud element.
A system, comprising:
- a gearbox comprising a housing enclosing at least one rotating gear, the housing having an inner surface defining a hollow interior in which the at least one rotating gear is accommodated;
- a combined oil shroud and oil pickup accommodated within the hollow interior of the housing, the combined oil shroud and oil pickup including an oil shroud element shaped and sized to enclose a lower portion of the at least one rotating gear and an oil intake element accommodated within the hollow interior of the housing, the oil intake element including an oil outlet configured to couple to an inlet of a pump and an oil pickup comprising at least one orifice, the combined oil shroud and oil pickup having a shared intermediate portion that forms both a portion of a top of the oil intake element and a portion of a bottom of the oil shroud element.
A system, comprising:
- a gearbox comprising a housing enclosing at least a first rotating gear and a second rotating gear, the first rotating gear having teeth meshed with teeth of the second rotating gear;
- and
- an oil shroud and pickup accommodated within the housing, the oil shroud and pickup comprising:
- an oil shroud element comprising a first curved portion sized and shaped to enclose a lower portion of the first rotating gear, a second curved portion sized and shaped to enclose a lower portion of the second rotating gear, and an intersecting region positioned between the first curved portion and the second curved portion, wherein each of the first curved portion, the second curved portion, and the intersecting region are aligned along a common longitudinal axis and have a common first width;
- and
- an oil intake element accommodated within the housing and coupled to the oil shroud element directly below the second curved portion and including an oil outlet configured to couple to an inlet of a pump and an oil pickup comprising at least one orifice, and wherein the oil outlet and the oil pickup are aligned relative to the common longitudinal axis such that the oil intake element has a second width that is less than the first width.
