  • Patent number: 10697498
    Abstract: An assembly for an epicyclic reduction gearset, including a satellite carrier, satellites, and at least one satellite bearing including a central axis linked to the satellite carrier. An inner ring mounted on the central axis, an outer ring mounted to rotate around the central axis. A lubrication circuit brings a flow of oil between the rings. The lubrication circuit includes a first portion supplied with oil with openings to the outside of the inner ring in a radially inner area of the bearing. A second portion has openings to the outside of the inner ring. An intermediate portion has at least one channeling connecting the first portion to the second portion, having at least one singular pressure reduction formed by an elbow and at least one flattening of a transverse cross-section. The central axis has a radially outer first surface. The inner ring has a radially inner second surface.

  • Patent number: 10550723
    Abstract: A wheel for distributing a lubricant in a turbine engine has an axis from which an annular cavity extends, open radially towards the axis and from which first and second lubricant supply lines depart for various members to be lubricated. Parallel to the axis, the annular cavity is split into at least a first and a second annular sub-cavity, which are separated by a substantially radial partition and which communicate with the first and second lines respectively.

  • Patent number: 10458279
    Abstract: A bowl for supplying oil to at least two oil-distribution circuits which are connected to a planet carrier of an epicyclic reduction gearbox, the planet carrier rotating and the oil coming from a fixed oil ejector, the bowl being designed to be secured to the planet carrier and having a substantially cylindrical shape and being open radially towards the inside with respect to an axis. The bowl is divided into a circumferential succession of separate cups each designed to communicate with one of the oil distribution circuits A reduction gearbox with its supply device and a method of operation in a turbomachine are also disclosed.

  • Publication number: 20190032514
    Abstract: The invention relates to a wheel (35) for distributing a lubricant in a turbine engine, wherein the wheel has an axis from which an annular cavity extends, open radially towards the axis and from which first and second lubricant supply lines (43, 45) depart for various members to be lubricated. Parallel to the X axis, the annular cavity is split into at least a first and a second annular sub-cavity, which are separated by a substantially radial partition (38) and which communicate with the first and second lines (43, 45) respectively.
