Embodiment Construction

[0020] figure 1 A gear system configuration 10 according to the prior art is shown on a foundation 18 . The gear system configuration 10 includes a frame 16 to which the vacuum roll 12 is connected by a carrier bearing assembly 20 . The carrier bearing assembly 20 is attached to the interior of the frame 16 such that the vacuum roll 12 is supported on the frame 16 from its flanged shaft 32 through the carrier bearing assembly 20 . The structure 14 inside the vacuum roll is supported by a carrier ring 28 ′ which is connected to the frame 16 . Vent holes 40 are provided in the carrier ring 28'. The vacuum roll 12 includes a flanged shaft 32 and a housing 34 . A gear 22 for driving the vacuum roll 12 is connected to the vacuum roll 12, more particularly to a flanged shaft 32 of the vacuum roll. The vacuum connection of the vacuum roll is connected to the carrier ring or to the inner structure of the vacuum roll carried by it. The gearbox 24' is located inside the carrier rin...

Abstract

The invention relates to a gear-system arrangement (10) for driving a vacuum roll (12) and for supporting the internal structures (14) of a vacuum roll (12), which gear-system arrangement (10) includes: a machine frame (16) fitted to a supporting foundation (18), a carrier-bearing assembly (20), attached inside the machine frame (16), for supporting the vacuum roll (12) on the machine frame (16) from outside the vacuum roll (12), a gearwheel (22) attached to the vacuum roll (12), for driving the vacuum roll, a gear housing (24) for transmitting torque, a drive-bearing assembly (26) between thegearwheel (22) and the gear housing (24), a carrier ring (28) for supporting the vacuum roll's internal structures (14) from the machine frame (16), and the gear housing (24) has been integrated as part of the carrier ring (28). In addition, the gearwheel (22) and the vacuum roll (12) are connected to each other by a flexible coupling (30).

Description

technical field [0001] The invention relates to a gear system configuration for driving a vacuum roll and for supporting the internal structure of the vacuum roll, said gear system configuration comprising: [0002] - rack mounted to the supporting foundation, [0003] - a carrier bearing assembly attached to the inside of the frame for supporting the vacuum roll on the frame from the outside of the vacuum roll, [0004] - a gear connected to the vacuum roll for driving the vacuum roll, [0005] - gearbox for torque transmission, [0006] - the drive bearing assembly between the gear and the gearbox, and [0007] - Carrying ring for supporting the inner structure of the vacuum roll from the frame, the gearbox is integrated as part of the carrying ring. Background technique [0008] figure 1 A vacuum roll gear system configuration known in the prior art is shown. The gear system configuration includes a frame on which the vacuum roll is supported by a carrier bearing as...
