1. A device for lubricating a transmission (1) as well as a bearing (1

  • ), in particular a rotor bearing in a wind turbine, wherein the transmission (1) and the bearing (1

    ) are each associated with at least one lubrication circuit (3, 5) of the device, in each of which circuit a lubricating medium flows during the operation of the device, characterized in that the device has a heat exchanging device (7, 59, 61) for heat transfer between the lubrication circuit (3) of the transmission (1) and the lubrication circuit (5) of the bearing (1

    ), and that during the operation of the device, the heat exchanging device (7, 59, 61) a difference between the temperature of the lubricating medium in the lubrication circuit (3) of the transmission (1) and the temperature of the lubricating medium in the lubrication circuit (5) of the bearing (1

    ) are at least partially compensated for through heat equalization.
