Abstract
A gear unit for the drive of a rotating tube is provided with a drive shaft and a power distributing gear unit stage that is configured as a helical gear unit with an intermediate shaft having mounted thereon two helical pinions. A load-summing gear unit stage with a take-off shaft is operated downstream of the gear unit stage. In this connection, the take-off shaft is on the central axis of the driven rotating tube. The load-summing gear unit stage is comprised of two parallel operated planetary gear units each having a sun gear, planetary gears each disposed on a respective planetary axle, a hollow gear and a common planet carrier that is configured as a single piece and connected with the take-off shaft. The planetary axles of both planetary gear units in the common planet carrier are spaced from one another and offset from one another. The intermediate shaft of the helical gear unit and the planetary gear units are supported in floating bearing arrangement, whereby the helical gear unit and the planetary gear units form a symmetrical planetary gear unit combination.
