Balancing
Because of primary shaping processes and machining, the cou-
pling components are manufactured with a mass distribution
about the axis of rotation of the motor, gear unit or driven ma-
chine which is not always ideal.

平衡质量水平

单级和两级平衡
对于盘状体（例如制动盘，耦合轮毂），
called single-level balancing is carried out. The mass compen-
不平衡的原样仅在一个层面上进行。为了
历史原因单层平衡也被称为静态
balancing. On long bodies such as adapters mass compensa-
tion must be implemented at two levels to reduce the couple im-
balance. Two-level balancing is carried out while the rotor body
正在旋转。从历史上看，这被称为动态平衡。

tors have frequently been balanced in accordance with the full

Half parallel key standard
The balancing standard normally applied today. Before balanc-
在g, a half parallel key is inserted in the shaft and another in the
耦合在g hub. Alternatively, balancing can be carried out before
cutting the keyway. The balanced parts must be marked with an
"H". This marking can be dispensed with if it is absolutely clear
which parallel key standard has been applied.
