An oil supply device intended to supply oil to an epicyclic reduction gear, the oil coming from at least one oil injector fixed with respect to the reduction gear, the oil supply device including at least one cup which is integral with a planet carrier of the reduction gear and substantially annular open radially with respect to an axis of the reduction gear and the walls of which delimit a cavity supplied by the at least one oil injector and which supplies at least one of the oil distribution circuits of the reduction gear. The oil supply device is staged and includes at least two independent stages provided with cups coaxial, of different diameters, each supplying an associated oil circuit and configured to receive the oil axially, centripetally, or tangentially, or according to an inclined direction combining two of the directions.

An insert for supplying a fluid to splines of a drive shaft, the insert comprising an insert wall extending between a first end and a second end of the insert, a chamber surrounding the insert wall for storing a fluid, a piston having a surface configured to be exposed to the fluid, the piston configured to move between a first position and a second position within the chamber, and the piston biased toward the first position, and wherein an increase in supply of the fluid in the chamber causes the piston to move toward the second position and a decrease in supply of the fluid in the chamber causes the piston to move toward the first position.

A continuously variable transmission includes a primary pulley, a secondary pulley, a metal belt wound around the primary pulley and the secondary pulley, and a controller. The metal belt includes a ring and a plurality of elements. The elements have respective receiving portions opening in a radial direction of the belt and receive the ring in the receiving portions. The controller executes a preliminary determined falling-off countermeasure control of the element when the end play larger than the predetermined length is detected to be generated or the continuously variable transmission is detected to be under the operation condition in which the end plays concentrate.

A line of vehicle transmissions is provided. The vehicle line includes a first multi-stage gear train assembly with at least two stages, a second multi-stage gear train assembly with at least three stages, and a housing including a first section removably attached to a second section. The second housing section is configured to receive the first and second multi-stage gear train assemblies in different product arrangements.

Systems and methods are presented herein for lubricating a differential assembly using a double baffle assembly. The differential assembly comprises a lubrication jet, an output gear, and the double baffle assembly. The output gear comprises openings and the lubrication jet is aligned with the openings in the output gear. The double baffle assembly comprises an inner baffle and an outer baffle that collectively form a slot aligned with the openings in the output gear. The inner baffle is configured to guide lubrication expelled from the lubrication jet towards the openings in the output gear, regardless of whether the differential assembly is in an engaged state or disengaged state.

A gearbox for a gas turbine engine with a rotatably mounted structural component that is formed with an at least approximately rotationally symmetrical duct into which, starting from its radially inner area, oil from an oil supply which is fixedly attached at the housing can be introduced. Starting from the oil supply, an introduction direction of the oil into the duct encloses an angle of 90° or an angle of between 60° and 90° with the axial extension direction of the duct. Additionally, in the circumferential direction of the duct, the introduction direction of the oil encloses an angle with the radial extension direction that is larger than or equal to 0° and smaller than 90°.

The present invention relates to a drive for reaching a desired position of a component such as of a rotor blade, a crane tower, a superstructure and the like, having at least two drive elements that are in toothed engagement with one another and of which at least one is drivable from a drive source and the other is connectable to the component, and having a lubricating device for lubricating the drive elements, wherein at least one lubricant passage for the supply of lubricant to a meshing tooth pair is led through one of the drive elements. It is proposed to effect the supply of the lubricant by a distributor that is connected upstream of the lubricant passage integrated in the drive element and to control the connection between a supply passage of the distributor and the at least one lubricant passage integrated in the drive element by a relative movement between the drive element and the distributor.

A planetary gearbox includes a planet carrier, with a planetary gear rotatably disposed on the planet carrier, and a gear that meshes with the planetary gear, as well as a gas turbine engine having such a planetary gearbox. The planet carrier has an oil supply installation including a supply line for oil to an opening. The oil is directed out of the opening in the direction of the planetary gear and/or the gear. The oil supply installation in relation to a primary rotating direction of the planetary gear and/or the gear in front of the opening includes a shielding region which protrudes from an external side of the oil supply installation and which by way of the external side of the oil supply installation on a side that faces the primary rotating direction of the planetary gear and/or the gear, delimits an oil collection groove.

The invention concerns an epicycloidal gear train comprising a central pinion (26), an outer crown (28) and satellite pinions (32) in engagement with the central pinion (26) and the outer crown (28) and each mounted freely rotatable on a satellite carrier (36), the gear train (10) comprising means for lubricating the teeth and axes (34) of the satellite pinions (32), these means including an annular cup (56) integral with the satellite carrier (36) opened radially inward. According to the invention, an annular bailer (64) is arranged radially inside the cup (56) and applied annularly sealingly to it, the annular bailer (64) being fixed in rotation to the central pinion (26).

A method for monitoring a fluid system for lubricating a mechanical system. The fluid system comprises a spraying circuit connected to a main fluid circuit and to a back-up fluid circuit. The back-up fluid circuit comprises a back-up check valve closed in a nominal operating mode. The method comprises a monitoring phase comprising the generation of a first alert in the presence of the detection of a malfunction making the main fluid circuit inoperative and the back-up check valve in an open state and the generation of a second alert different from the first alert in the presence a malfunction and the back-up check valve in a closed state.
