<p>Drive unit comprises of at least two drives, which are coupled for driving a load such that at least a first drive (G1) is connected with the load by a first coupling device (K1) and at least a second drive (G2) is connected by a second coupling device (K2) with the load, whereby each coupling device exhibits at least two types of claws. The claws have right and left flanks, which are present in circumferential direction. In a first operating mode, in particular in error free operation, always a basic load is intended in such a manner that only one type of the flanks, in particular the right flanks of claws are transmitted. In a second mode of operation, in particular in case of blockade of a drive, the other type of flanks, in particular the left flanks of claws are applied. In the second mode of operation after turning at an angle, in particular after overcoming of static friction and a spring action, the coupling device is decoupled and an element irreversible up to next maintenance or repair fixes this decoupled condition. An independent claim is also included for the method involves for operation of the plant.</p> |
