  • Patent number: 11773961
    Abstract: A planetary gearbox of a gas turbine engine has a planet gear which, via a bearing, is arranged rotatably on a planet pin of a rotatable planet carrier. Oil is introduced through an opening, arranged radially within the bearing, into an oil feed which is open at a feed side and which is connected to the bearing and rotationally joined to the carrier. As the carrier rotates, the oil downstream of the opening is conducted toward the bearing unit by centrifugal force. The open oil feed is, between the opening and the bearing, configured an oil filter through which the oil is conducted. The filter extends counter to the flow direction of the oil from the opening in the direction of the bearing unit, in a flow direction of the oil in the open oil feed.

  • Publication number: 20230062203
    Abstract: A gear box assembly for an engine, having a gear box for transmitting a torque, at least one first, static part, at least one second, rotating part, which is mounted so as to be rotatable relative to the first, static part and on which at least one element of the gear box is provided, and a conduit system for conveying a fluid to elements of the gear box, wherein the conduit system has at least one first supply line and one second supply line for supplying fluid to at least one element of the gear box. A leakage recovery facility is provided, by means of which at least a proportion of a leakage flow of fluid which originates from a first duct portion of the first supply line and which flows across at least one seal can be conducted to the second supply line.

  • Publication number: 20230067829
    Abstract: The proposed solution relates to a gear box assembly for an engine, having a gear box for transmitting a torque, at least one first, static part, at least one second, rotating part, which is mounted so as to be rotatable relative to the first, static part and on which at least one element of the gear box is provided, and a conduit system for conveying a fluid to elements of the gear box. A feed device of the conduit system on the first, static part has at least two separate fluid guides, of which a first fluid guide is provided for guiding fluid from at least one first feed opening to a first supply line in the second, rotating part and a second fluid guide is provided for guiding fluid from at least one second feed opening to a second supply line in the second, rotating part.

  • Publication number: 20220099175
    Abstract: The invention relates to a planetary gear box having at least one seal system, which has at least one rectangular-section sealing ring, which is arranged in a groove device, wherein the at least one rectangular-section sealing ring rests at least partially against a groove flank of the groove device, and the groove flank has profiling between the groove flank and the rectangular-section sealing ring for the purpose of distributing fluid, in particular oil, applied to the seal system, wherein the at least one seal system is part of an oil supply of a planet carrier and the seal system has at least two rectangular-section sealing rings, which are spaced apart axially from one another and are arranged radially between a drive shaft of the planetary gear box and the planet carrier. The invention also relates to a gas turbine engine.

  • Patent number: 10823174
    Abstract: A planetary gearbox device, a gas turbine engine with a planetary gearbox device, and a method for producing a scoop pump. The planetary gearbox device includes an oil supply appliance, wherein the oil supply appliance has a ring-shaped scoop pump that is connected to the rotatable shaft of the planetary gearbox device and an oil supply fixedly arranged at the housing and by which oil is supplied to the scoop pump. The scoop pump has multiple blades that extend in a circumferentially arranged manner and extend from a radially outer area in the direction of a radially inner area. The blades delimit grooves extending in the circumferential direction in the radial direction and respectively form a groove base of the grooves. The oil is conducted from the oil supply to outlets via which oil is conducted out of the scoop pump in the radial direction outwards.
