Machine with a drive train
A machine includes a drive train having a drive unit, an output unit, and a gear unit interconnecting the drive unit and the output unit and configured to be in a non-grounded state with respect to the machine environment during a normal operation of the machine. An insulation is provided to electrically insulate a connection between the gear unit and the drive unit and/or a connection between the gear unit and the output unit.
1. A machine, comprising:
a drive train having a drive unit, an output unit, and a gear unit between the drive unit and the output unit and configured to be in a non-grounded state with respect to the machine environment during a normal operation of the machine; and
an insulation configured to electrically insulate a connection between the gear unit and the drive unit and a connection between the gear unit and the output unit, wherein the gear unit has a safety facility configured to automatically ground the gear unit in an event of danger.
2. The machine of claim 1 , further comprising a peripheral device connected to the gear unit and electrically insulated with respect to the machine environment during the normal operation of the machine.
3. The machine of claim 1 , wherein the gear unit has electrically insulated bearings.
4. The machine of claim 1 , wherein the gear unit has an active potential compensation facility to actively control a potential of the gear unit.
5. A method for operating a machine with a drive train having a drive unit, an output unit, and a gear unit between the drive unit and output unit, comprising maintaining a gear unit of the drive train of the machine in a non-grounded state during a normal operation of the machine, electrically insulating a connection between the gear unit and the drive unit and a connection between the gear unit and the output unit, and maintaining the gear unit automatically grounded in an event of a danger.
