An oil restrictor for emergency lubrication of a component for an aircraft turbine engine includes a metal cylindrical body having a longitudinal axis and configured to be housed in and shrink-fitted into a cylindrical bore of a part of the turbine engine. The restrictor further includes an integrated oil circuit enabling oil to pass through the restrictor along the axial extent thereof. The body is a one-piece body, and the circuit has at least two oil channels recessed on an outer cylindrical surface of the body and extending around and/or along the axis.

Gearboxes for aircraft gas turbine engines, in particular to arrangements for journal bearings such gearboxes, and to related methods of operating such gearboxes and gas turbine engines. Example embodiments include a gearbox for an aircraft gas turbine engine, the gearbox including: a sun gear; a plurality of planet gears surrounding and engaged with the sun gear; and a ring gear surrounding and engaged with the plurality of planet gears, each of the plurality of planet gears being rotatably mounted around a pin of a planet gear carrier with a journal bearing having an internal sliding surface on the planet gear and an external sliding surface on the pin.

The present invention improves the drainability of lubricating oil at a thrust bearing. The present invention comprises: a rotating shaft; a thrust bearing that is provided to the rotating shaft and restricts the axial-direction movement of the rotating shaft; and an oil reservoir part (20) that has formed therein an oil reservoir space (20a) that is provided to be adjacent to the thrust bearing in the axial direction and to open downward, the oil reservoir space (20a) having formed therein an inclined surface (20aa) that, in a region that is in and below a horizontal plane H that passes through the center of the rotating shaft, protrudes to the thrust bearing side and is inclined along the rotational direction of the rotating shaft.

An axle assembly includes a carrier housing, a ring gear disposed within the carrier housing, and a pinion meshed with the ring gear. The pinion is coupled with a pinion shaft rotatably supported in the carrier housing by at least one bearing. A sump and a fluid catch are disposed in the carrier housing. A conduit having a regulator is in fluid communication with the fluid catch and the at least one bearing.

The present disclosure provides a reducer for an electric vehicle, the reducer including an input shaft connected to a motor, a differential disposed coaxially with the input shaft and relatively rotatable, a planetary gear train configured to decelerate power of the input shaft and transmit the power to a differential casing of the differential, and a drive shaft configured to penetrate the input shaft and coupled to one side gear of the differential.

A link chain, in particular bush chain, comprising an inner link plate with a bush, an outer link plate with a pin, wherein the pin and bush form a chain joint, wherein a sealing arrangement is provided for sealing the chain joint, wherein the sealing arrangement is arranged between the inner link plate and the outer link plate, and wherein the sealing arrangement comprises a seal and a seal-accommodating space, characterized in that in that the seal-accommodating space is formed from a thrust washer and an annular cutout, in particular in the outer link plate, wherein a ring, which is designed in the form of a metal ring, is arranged in the seal-accommodating space, or in that the seal-accommodating space is formed from a thrust washer and an accommodating washer.

A shroud is provided and includes first and second curved sections, at least one of which defines a main interior channel and at least one of first and second lube jet sections integrated with the first and second curved sections. The first lube jet section includes a summit at which proximal portions of the first and second curved sections meet and defines a first jetting interior channel fluidly communicative with the main interior channel and terminating at the summit. The second lube jet section includes an elongate member extending from one of the first and second curved sections and defines a second jetting interior channel fluidly communicative with the main interior channel and terminating at a distal end of the elongate member.
