Do you know the balance correction method and principle of diaphragm coupling? Today, Jiangsu Handes diaphragm coupling will take you to find out!

   1. Due to various reasons, the center of mass or inertial principal axis of the diaphragm coupling does not coincide with the axis of rotation. During operation, the phenomenon of unbalanced centrifugal inertial force, centrifugal inertial couple force and dynamic deflection (vibration shape) will occur, which is called The unbalance phenomenon of the rotor, this unbalance phenomenon will inevitably cause the vibration of the shaft system, thereby affecting the normal operation and service life of the machine, so it is important to pay attention to it.

   2. The degree of unbalance (unbalance U) is usually expressed by the product mr of the mass m of the rotor and the distance r from the center of mass to the axis of rotation of the rotor, which is called the product of mass diameter. It is also expressed by the product of mass diameter per unit mass, which is called the eccentricity e (not geometrically eccentric.) The product of mass diameter mr is a relative quantity related to the mass of the rotor, while the eccentricity e is a value that has nothing to do with the mass of the rotor.的量。 The amount.

3. The former is relatively intuitive and is often used for the balancing operation of a specific given rotor, while the latter is used to measure the pros and cons of the rotor balance or to check the balance accuracy. The balance grade standard of the coupling is evaluated by e. For a flexible rotor, use the mode eccentricity (the nth mode) en=Un/mn, and Un and mn are the nth mode and the mass of the first mode respectively.

   4. In order to correct or minimize the unbalance of the coupling, select the appropriate balance level according to the needs, and after the product is manufactured and installed on the machine, on the balance (correction) plane designated by the coupling , By increasing or decreasing the appropriate quality method to achieve the balance level requirements. This process is called balance correction, or balance for short.

   The above is the relevant information of Jiangsu Handes diaphragm coupling, I hope it will be helpful to everyone!
