Product details

couplingDue to various reasons, the center of mass or inertia axis of the rotor does not coincide with its rotational axis, resulting in unbalanced centrifugal inertia force, centrifugal inertia couple force, and dynamic deflection (vibration mode) during operation, which is called rotor unbalance phenomenon. This unbalance phenomenon will inevitably cause vibration of the shaft system, thereby affecting the normal operation and service life of the machine. Therefore, it must be taken seriously. The degree of imbalance (unbalance U) is usually expressed as the product of the mass m of the rotor and the distance r from the center of mass to the axis of rotation of the rotor, called the mass radial product. It is also expressed in terms of the product of mass and diameter per unit mass, known as eccentricity e (not in a geometric sense). The product of mass and diameter mr is a relative quantity related to the mass of the rotor, while eccentricity e is an absolute quantity independent of the mass of the rotor. The former is more intuitive and commonly used for balancing operations specific to a given rotor, while the latter is used to measure the quality of rotor balance or detect balance accuracy, as well as the balance level of the couplingstandardEvaluate according to e. For flexible rotors, the mode eccentricity (n-th mode) en=Un/mn is used, where Un and mn are the mass of the n-th mode and mode, respectively.
