The mass diameter product mr is a dependent quantity related to the stator quality

Such imbalance will inevitably cause the shafting Vibration, which will endanger the trouble-free work and life of the equipment. The mass diameter product mr is a dependent quantity related to the stator quality, and the eccentricity e is an absolute quantity irrelevant to the stator quality. In high-speed and heavy-duty power transmission, some couplings also have cushioning, damping and improving the dynamic performance of the shafting effect. It is also effectively expressed by the mass diameter product of enterprise quality, which is called eccentricity e. 

The balance correction of the coupling is very important at work, which is related to the service life of the coupling. The balance grade specification of the coupling is identified by e. In order to correct or reduce the coupling’s potholes to a larger limit, the appropriate balance level should be selected based on the need to select the appropriate balance level, and after the finished product is manufactured and installed on the equipment, the specific balance (correction) vertical plane of the coupling According to the method of improving or reducing the moderate quality, make it exceed the equilibrium level requirement. 

The level of unbalance (unbalance U) is generally expressed by the product mr of the stator mass m and the distance r between the center of mass and the rotation centerline of the stator, which is called the product of mass diameter. The former is used to consider the quality of the stator balance or to test the precision of the balance. This is necessary in our daily use and maintenance process.

 Pay special attention. However, when the coupling is working, due to various reasons, the center of mass or the inertial principal axis does not coincide with the axis of rotation to produce an imbalance. Should we adjust this? Why should the coupling be balanced and corrected? How to balance correction? When the coupling is in operation, it will cause unbalanced suction filter force, suction filter air resistance coupling force and dynamic stiffness (vibration shape), which is called the imbalance of the stator. Extending the service life of the coupling also requires routine maintenance.

 For the flexible stator, the mode eccentricity (the nth mode) en=Un/mn is used, and Un and mn are the nth mode CV Axle Suppliers and first mode quality respectively.. The two are more visualized, and are often used in actual balanced use of the stator.Couplings are mechanical parts used to connect two shafts in different mechanisms so that they can rotate together to transmit torque. The correct balance correction can effectively increase the service life of the coupling
