Abstract
The present invention relates to an exchangeable milling drum box for a ground milling machine, particularly for a road milling machine, a recycler, a stabilizer or a surface miner, with a milling drum rotatably mounted in the exchangeable milling drum box and a transmission, via which the milling drum can be driven, the transmission comprising a lubrication device with a lubricant, and the exchangeable milling drum box comprising a cooling and/or heating device for lubricant. Furthermore, the present invention relates to a ground milling machine having such an exchangeable milling drum box. The present invention also relates to a method for cooling and/or heating lubricant of a transmission of a milling drum mounted rotatably in an exchangeable milling drum box of a ground milling machine, the method comprising the steps: Supplying cooling and/or a heating medium from the ground milling machine to the lubricant located in a lubrication device arranged on the exchangeable milling drum box; cooling and/or heating the lubricant through heat transfer between the coolant and/or heating medium and the lubricant; and discharging the cooling and/or heating medium from the exchangeable milling drum box to the ground milling machine.
