Abstract

By accommodating a gear wheel of a transmission (9 ') on the shaft (8') of a work machine (5 ', 16) and integrating a bearing of the work machine (5', 16) into the transmission (9 '), a compact space-saving can be achieved Represent drive that allows simplified assembly. The invention is used in particular in generators (5 ') which are driven by turbines (1'). DOLLAR A Thanks to the integrative design, a gear shaft, an additional bearing and a coupling can be dispensed with compared to the prior art.

Description

The invention relates to a transmission, in particular for Drive of generators is provided. However, it is also possible with the Verdich gear arrangement according to the invention motor or other machines with a motor ben. The transmission according to the invention is preferably as Planetary gearbox executed.

[State of the art]

The invention is based on a turbine that has a Clutch is connected to a reduction gear, which uses a further coupling to generate a generator generation drives. With such an arrangement they are Shafts of generator and turbine are radially ver against each other puts. When installing such a system, the generator aligned to the transmission and the transmission to the turbine become. The systems described consist of many construction groups and require a large installation space.

OBJECT OF THE INVENTION

Proceeding from this, it is the object of the invention compact space-saving drive for generators fen, which allows a simplified assembly.

The object is achieved by the characterizing Features of claim 1 solved.

Due to the arrangement of the modules according to the invention Construction weight of the gearbox reduced by up to 50%.

The turbine and the generator are advantageously mounted with aligned shafts.

Due to the integrative structure, an inventive one Plant a short length.  

The short and narrow construction reduces the Space requirements and construction costs as well as the costs for the smaller foundation frames are reduced.

Furthermore, there is no additional foundation for the transmission required.

By attaching the generator bearing close to the drive Gearbox and the inclusion of a ring gear through the Flange of the generator shaft can be saved due to the saving Gear shaft advantageously on an additional Bearings in the gearbox and a second clutch are dispensed with become. This integration into an assembly makes it unnecessary a complex alignment process when installing the system. It is only the turbine to the gear generator unit in Bring to escape, which makes assembly much easier is.

The acquisition and assembly costs for the invention omitted modules are saved.

[Examples]

Through the drawings described below the constructive design explained in more detail. Show:

Fig. 1 schematic diagram of the arrangement according to the prior art,

Fig. 2 shows a schematic sketch of the arrangement according to the invention,

Fig. 3 constructive structure of a gearbox according to the invention.

In Fig. 1 shows a basic arrangement of the drive of a generator (5) is illustrated. A turbine ( 1 ) is connected to a transmission ( 3 ) via a shaft coupling ( 2 ). The transmission output shaft, which is radially offset from the Eintriebswel le of the transmission ( 3 ), drives a generator ( 5 ) via a further clutch ( 4 ). The generator shaft ( 8 ) is supported at its free end by a bearing ( 7 ) and at its end near the gear by a bearing ( 6 ).

Fig. 2 shows the arrangement according to the invention as Prin zipskizze. A turbine ( 1 ') drives a shaft coupling ( 2 ') into a gearbox ( 9 ') which is connected to the foundation and supports the generator shaft ( 8 ') on the drive side. The shaft of the turbine ( 1 '), the input and output shaft of the transmission ( 9 ') are aligned with the generator shaft ( 8 ') of the generator ( 5 '). The free end of the generator shaft ( 8 ') is supported by a further bearing ( 7 ').

The gear arrangement according to the invention can also be used in other application examples. Conceivable with play, the drive of a compressor (17) with a motor (16) via the gear (9 ') and the coupling (2') is connected to the compressor (17).

FIG. 3 is a constructive arrangement example again. A transmission shaft ( 14 ) is driven by the turbine, not shown, via a shaft coupling, also not shown. The gear shaft ( 14 ) has at its end, which is located inside the planetary gear ( 9 "), a central wheel ( 12 ) which drives into several planet wheels ( 11 ) rotatably mounted in the fixed housing ( 13 ). Together with the ring gear ( 10 ) via which the output takes place, these components form the planetary gear ( 9 "). The ring gear ( 10 ) is flanged to the generator shaft ( 8 ") at the transmission end. This gear wheel ( 10 ) can be carried directly or indirectly by the generator shaft ( 8 "). The Genera torwelle ( 8 ") thus also takes on the task of a transmission output shaft and is guided radially and axially between the transmission ( 9 ") and the schematically illustrated generator ( 5 ") in a bearing ( 6 "). This bearing ( 6 ") of the generator ( 5 ") is flanged to the planetary gear ( 9 "). Through this integration, the generator ( 5 ") together with the planetary gear ( 5 ") forms a fixed structural unit, which is on a common machine carrier ( 15 ). Instead of the generator ( 9 "), a motor ( 16 ) can also be installed, which in the same arrangement of the structural units drives in the opposite direction into the transmission ( 9 ") and drives off via the transmission shaft ( 14 ).

Essential essence of the invention as set out in claim 1 is that a bearing is saved, preferably a gearbox bearing as both the last element of the gearbox as well as the driven end of the shaft of the machine in a warehouse, preferably in a warehouse of labor machines are stored. A work machine can preferably can be a generator, but can also be an engine, wind turbine, turbo ne, compressor or the like.
