    • A method facilitates simultaneously balancing mechanically coupled, synchronously rotating rotors. The rotors have different axes of rotation relative to one another and together define a rotor group to be balanced. Each rotor has at least one of a bearing plane and an other measuring plane associated therewith, the other measuring plane significantly describing vibrations of the each rotor. The rotors within the rotor group together have a number of different angular velocities associated therewith. At least one rotor of the rotor group is equipped with at least one vibration pickup in at least one of each bearing plane and the other measuring plane thereof. As many impulse and phase transmitters are installed in the rotor group as are provided the number of different angular velocities associated with the rotors within the rotor group. At least pertaining vibration signals and a pertaining speed signal are recorded simultaneously, with regard to a respective one of each bearing plane and the other measuring plane. For each bearing plane and the other measuring plane, the coefficients of influence thereof are determined by applying a method of coefficients of influence and setting defined test unbalances. At least one corresponding matrix of coefficients of influence is generated, and a counterbalance mass distribution from the at least one corresponding matrix of coefficients of influence is determined for every operating balance plane of the rotor group. Each bearing plane and measuring plane define one test balance plane.
    • 一种方法有助于同时平衡机械耦合的,同步旋转的转子。 转子相对于彼此具有不同的旋转轴并且共同限定要平衡的转子组。 每个转子具有与其相关联的支承平面和另一测量平面中的至少一个,另一个测量平面显着地描述了每个转子的振动。 转子组内的转子一起具有与其相关联的多个不同的角速度。 转子组的至少一个转子在每个支承平面和另一个测量平面中的至少一个中配备有至少一个振动拾取器。 转子组中安装了许多脉冲和相位变送器,因为与转子组内的转子相关的不同角速度的数量。 关于每个支承平面和另一个测量平面中的相应一个,至少相关振动信号和相关速度信号被同时记录。 对于每个轴承平面和另一个测量平面,其影响系数通过应用影响系数的方法和设定定义的测试不平衡来确定。 产生影响系数的至少一个对应的矩阵,并且对于转子组的每个操作平衡平面确定来自影响系数的至少一个对应矩阵的平衡质量分布。 每个轴承平面和测量平面定义一个测试平衡平面。

    • A Yankee clyinder whose internally heated shell consists of steel or cast iron and is provided with an external layer of pure or alloyed copper, molybdenum, tungsten or another metal whose thermal conductivity greatly exceeds (and preferably amounts to at least twice) the thermal conductivity of the material of the shell. The thickness of the layer is in the range of 0.4-2 millimeters, and the thermal expansion coefficient of its material is identical to or approximates that of the material of the shell. The layer can be applied to the periphery of the shell in molten state in the form of a finely atomized spray. The drying action of such cylinder upon a running paper web greatly exceeds the drying action of a cylinder whose shell consists exclusively of cast iron or steel.
