Abstract
A planetary gearbox device for a turbomachine, having a planet carrier and at least one planet gear arranged rotatably thereon, is described. The planet gear is arranged in the axial direction between two planet carrier regions, to each of which at least one carrier element, on which the planet gear is rotatably mounted, is connected for conjoint rotation therewith. A wedging sleeve is arranged between the carrier element and each of the planet carrier regions, by means of each of which wedging sleeves a press-fit joint is established between the carrier element and the planet carrier regions. A sleeve is provided radially between at least one of the wedging sleeves and a planet carrier region.
