Mill equipment is segmented by a clutch of maximum dynamic load values ??starting with the time required to eliminate the gap is proportional to the fourth power dressing mill, and is inversely proportional to the square of the starting time, the mill start-up time (clutch engagement time) longer, dynamic load smaller, but the long start-up time will increase the clutch heat, reduce the service life of the clutch, a ball mill in addition to the starting process for some reason, since the driving motor may double the rotation frequency to generate torque, the torque during rotation harmonic and grid frequency moment, these transient moments are likely to excite torsional vibrations of mechanical systems, resulting in dynamic load, in addition, also as a result of too much starting torque, soft starter improper operation and the reasons for the gap and other gear, causing shock and vibration a ball mill, to produce dynamic load. Dynamic load when starting mill direct analysis, starting when the ball mill can be divided into three stages: 1. In the case of the work unit is not moving because there is a gap in the transmission system, the prime mover of the rotor acceleration. 2. The movement of the working device yet, due to the elastic deformation of the transmission system, prime mover of the rotor has been moved to the drive system until the force is equal to the external resistance. 3. Operating system begins to move in during the first and second phase, the prime mover of the rotor has a certain speed, the transmission system to obtain initial deformation, the deformation is acting on the working device adapted resistance. 4. The dynamic load segment starting mill is a ball mill drive train presence of occupied space, through the friction clutch segment start, from the power curve, and the angular velocity of the elastic force, the starting clutch torque increase mill works, driveline torque in the elastic member changes, the corresponding change in angular velocity. www.zzyuxi.com mill equipment is typical of large inertia overloaded equipment, design, manufacturing and site installation, you should take full account of the effects of vibration dynamic load. 1. gap mill ball mill drive systems have a greater impact on the dynamic load at the start, and the drive gear clearance gap primarily, if not high precision gear manufacturing, it will have a gap. 2. The impact of dynamic load stiffness is proportional to its secondary ball mill, ball mill for the segment start, due to the use of the flexibility larger pneumatic clutch or hydraulic coupling, the system will help reduce stiffness. 3. Reduce the stiffness of the system can increase the durability and life of mill transmission equipment, because the elastic vibration vibration period of the extension system, while the natural frequency is reduced.
