Accompanying drawing explanation
Currently preferred improvement project is drawn by dependent claims and ensuing explanation.Elaborate embodiments of the invention with reference to the accompanying drawings, and be not limited to this.Wherein:
Fig. 1 shows the driving assembly of vertical roller mill.
Detailed description of the invention
The present invention relates to the driving assembly of a kind of vertical roller mill.The driving assembly of the vertical roller mill according to the present invention includes housing 10.Supporting at housing 10 and have pressing plate 11, it can rotate around vertical pressing plate rotation axis 12 and it forms the output unit driving assembly.Under pressing plate 11, there is actuating device 13 location in the housing 10, and it is in rotation drive connection with pressing plate 11.Being disposed with multiple motor 14 the most in the housing 10 under actuating device 13, it is in rotation drive connection via actuating device 13 and pressing plate 11.Assembly is driven to include quantity N=8 motor 14 in an illustrated embodiment.But this quantity is purely illustrative matter.Also can exist less than N=8 or more than N=8 motor 14.But the quantity of motor 14 is more than two, be i.e. suitable for N > 2.N > 4 be preferably, N >=6 be particularly preferred.
In the driving assembly according to the present invention, squirrel cage motor that motor 14 is all configured to asynchronous working without rotational speed regulation ground, that have revolutional slip.According to the present invention the most do not use MS master-slave-driving assembly (as this in the prior art or the most common as), but use the squirrel cage motor 14 that is not conditioned of rotating speed.Thus can reduce the consuming on regulation technology.
In embodiment shown in fig. 2 in motor 14 each, i.e. rotating speed is unadjusted, asynchronous working, have and each respectively can be attached at power supply network 16 via the switching device 15 that can individually handle in the squirrel cage motor of revolutional slip, wherein, the switching device 15 of the embodiment of Fig. 2 is embodied as the simple switch that can be opened and close.
These switching devices 15 are controllable based on controlling device 17, the most so make in order to start driving component control device 17 first pass through Guan Bi corresponding switching device 15 by unique motor 14 or alternatively two motor 14 be attached at power supply network 16 simultaneously, wherein, control device 17 then passes through the corresponding switching device 15 of Guan Bi and is individually attached at power supply network 16 by another motor 14 the most respectively, that is until all N number of motor 14 are attached at power supply network 16.
If need not rotation speed change the most under a load in the period running driving assembly, then the assembly (each squirrel cage motor 14 controlled device 17 can be attached at power supply network 16 by Guan Bi switching device 15 with controlling successively wherein) of Fig. 2 is especially suitable for.
In order to start driving assembly, by correspondingly manipulating corresponding switching device 15 via control device 17, at least N-2 motor 14 is attached at power supply network 16 successively and the most individually, thus is driving the starting current (Anfahrstrom) at assembly to be limited.Because driving assembly to bear work moment (Arbeitsmoment) hardly when starting, assembly is driven to accelerate on the rotating speed according to revolutional slip foundation.Because all motor 14, the most all squirrel cage motors 14 are in lasting mechanical type drive connection, all driving motors have about the same rotating speed according to revolutional slip.If after starting driving assembly, all squirrel cage motors 14 are attached at power supply network 16, then can make driving component load.Load is assigned on each squirrel cage motor 14 about its revolutional slip in the scope of the magnetic manufacture deviation of squirrel cage motor 14 at this in the operating point (Betriebspunkt) of vertical roller mill.
Rotational speed regulation in the meaning of MS master-slave-driving assembly utilizes optional according to the driving assembly of the present invention.Work moment can be born the most in proportion by all squirrel cage motors 14 being in lasting mechanical type drive connection.Owing to the raising of the asynchronous revolutional slip of higher operation torque similarly results in the raising of the power provided by it at all squirrel cage motors 14
Distinguish with the embodiment of Fig. 2, it is also possible to replace simple switching device 15 to be associated with each squirrel cage motor 14 by single unshowned converter.Control device 17 in this case and manipulate all converters simultaneously, to be jointly attached at power supply network 16 by the motor 14 being configured to squirrel cage motor, the most all converters are the most so made to send same frequency but the output signal of arbitrary phase is for manipulating corresponding motor 14.The most correspondingly driving assembly to be jointly attached at power supply network 16 by manipulating converter associated there simultaneously by all motor 14 to start, wherein, converter sends same frequency but the output signal of out of phase.
If driving assembly to be in operation should change its rotating speed, then the driving assembly with such converter (it is equally without the work of rotational speed regulation ground) is favourable.Converter can manipulate into the manipulation signal of it is sent each other frequency that band changes and arbitrary phase place again by controlled device 17 the most in this case, in order to so causes rotation speed change at assembly driving.For the rotation speed change not being conditioned, control device 17 and frequency-theoretical value is correspondingly sent for all converters 15, but according to the feedback in the meaning of the unreal present regulation of the present invention.
