SPINDLE COUPLING MAINTENANCES cheduled inspections should be performedin order to achieve a long spindle life and proper operation.
    These first inspections are advised tobe:
    1) after 1-2 weeks.
    2) after 4-6 weeks.
    3) after 8-10 weeks.
    Later on, the inspections are to becarried out every 5-6 months or every4000-6000 hours, at least once a year.
    During these inspections, the gear rack should be thoroughly cleaned and the following checking have to be performed:
    a) Flange bolts tightening.
    b) Gear teeth wear control.
    c) Noise and vibrations. In case of anomalousnoise or vibrations , check immediately the cause.
    d) Be sure that no excessive grease leakageis present, caused by seal wear,grease nipple and plugs failure.
    Damaged components should be replaced.
    If toothed components are notreplaced it is advantageous to re-engagethe teeth in the same mesh in which they were running. Top and bottom spindles should be inter changed toequalize tooth wear .
    Always maintain an inventory of spareparts sufficient to insure continuity ofplant operation.
    All gear racks be guarded top revent accidents according to nationaland local safety rules.
