| As our company plan to research and open up the "shoes carry "Mill, during the "Fifth" pla "Fifth" pla plan, the thesisility with the mill that nearest size and nearest useful and get the correct digit to work for resolve the vibration problem in the design of the new mill.It is important rules that Research for Dynamic characteristics of the mill system of single -pinion drives in operation to prevent damage from the resonance between fix frequency and bestir frequencyIn this paper , the pattern of Pinion---Drive shaft---Decelerator gearvertical vibration in the mill system of single -pinion drives is established . Dynamic characteristics of vertical vibration is analyzed and calculated ,and its excitation loads are tested Simultaneously , the model of torsion vibration in system is also established, its dynamic characteristics is analyzed by using recurrence calculus method , thus , this methods current is verified . Finally , the paper studied the dynamic characteristics of 2.6x13m mill system.Mill system of single - pinion drives is lighten, so the design and run of mill system, bestir frequency must avoid inhesion.The design of drive shaft is rational in mill system of single - pinion drives.It is very large that damp of system effect to dynamic characteristics, so the damp is a important parameter.Load of gear box can be decided by measuring of low speed shaft contort. In mill system of single - pinion drives... |
