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.
