    gear mesh frequency is > f max what can i do ?????

    motor 2960 rpm drive apump whic have two shafts the first is the low speed shaft 2960 rpm have axial gear with 191 teeth and the second is The high speed shaft 21772 rpm have axial agear with 26 teeth mesh with the first gear as we all know GMF =no of teeth*rpm so 191*2960 = 565360 cpm =...

    the spectrum of motor show high amplitude

    internal inspection was carried out on variable pitch axial flow fan and i found that two links of haydrulic mechansim which moves the pitch of the fan blades were found broken and that is the cause of lossenes and unblanace problem which appear in the motor spectrum and thanks storng...

    the spectrum of motor show high amplitude

    e.motor 1465 rpm drive by t-belt overhung axial variable fan 291 rpm with 6 blades in the motor inboard and out board spectrum i see 0.2x and it is harmonic which reach 16 mm/sec rms (0.2*1465)=293 the high reading was at m1h.m1v.m2h.m2v.m2a i confused in the reason of this high vibration is...
