Abstract
A lubrication wheel for a speed reducer of a turbomachine, including an annular oil passage cavity which extends around the axis, an annular slot for supplying the cavity, and pipes for the passage of oil by centrifuging from the cavity into the pipes, and a frustoconical rim for collecting oil at the level of the slot, the wheel being formed by the assembly of at least two parts.
Claims16
A lubrication wheel for a speed reducer of a turbomachine, in particular of an aircraft, said wheel being configured to be rotated about an axis and having a generally annular shape about said axis the wheel comprising:
- at its internal periphery an annular oil passage cavity which extends around said axis,
- at its internal periphery an annular oil supply slot which extends around said axis and which opens out in the axial direction into said cavity for the purpose of supplying it with oil, and
- oil passage pipes extending radially with respect to said axis and the radially internal ends of which are connected to said cavity for the passage of oil by centrifugation from the cavity into the pipes,
- wherein the internal periphery of the wheel comprises a frustoconical rim for collecting oil at the level of said slot, and in that this frustoconical rim extends around said axis and is formed by a first annular part mounted and fixed axially in an annular body which defines at least part of the cavity and the pipes.
