Embodiment Construction

[0019] figure 1 A pump is used as an example to illustrate the principle of a differential system for a drive train. The working machine 1 is here the rotor of a pump, which is driven by a drive 4 via a drive shaft 2 and a differential 3 . The drive device 4 is preferably a medium-voltage three-phase electric machine, which is connected to an electrical grid 12 which, in the example shown, is a medium-voltage electrical network based on the medium-voltage three-phase electrical machine. However, the selected voltage level depends on the situation of use and in particular on the power level of the drive 4 and can have any desired voltage level without affecting the basic function of the system according to the invention. Depending on the number of pole pairs of the drive 4 , a design-specific operating speed range results. In this case, the operating speed range is the speed range in which the drive 4 can deliver a defined or desired or required torque or, in the case of an e...

Abstract

The invention relates to a drive train comprising a drive shaft (2), a drive machine (4), and a planetary gearbox (3) having three drives and three outputs, wherein one output is connected to the drive shaft (2), one drive is connected to the drive machine (4), and a second drive is connected to an electric differential drive (5). According to the invention, the differential drive (5) can be connected directly to a network (12) without a frequency converter, in order that the operation of the drive train is possible without a frequency converter.

Description

technical field [0001] The invention relates to a transmission system comprising a drive shaft, a drive unit and a differential, the differential having three drives or followers, wherein one follower is connected to the drive shaft and one driver is connected to the drive unit , and the second drive is connected to the electrical differential drive. [0002] Furthermore, the invention relates to a method for operating a transmission system comprising a drive shaft, a drive unit and a differential with three drives or drives, wherein one drive and The drive shaft is connected, one drive is connected to the drive, and the second drive is connected to the electrical differential drive. Background technique [0003] High-efficiency, variable-speed operation is frequently demanded of work machines, such as conveying devices such as pumps, compressors and fans, or such as mills, crushers, vehicles or, for example, energy generation plants. [0004] Furthermore, an electric moto...
