PREDICTIVE MAINTENANCE OF GEARING MACHINERY
VIBRATION ANALYSIS TOOLS
This paper presents the implementing maintenance management for
organizing and preparing system of spare parts to optimize repair time.
Planning the activities of repair and minimizing „downtime” of the machine can
be made only through detection of possible defects. The machine tools
reliability and safety increase, they give respectively operating costs decreased
lead to a better total cost. By studying the vibration signal produced by a gear in
a machine tool structure and the change of the signal related to the presence of
defects gear can identify various defects. Defects are localized at the contact
between the mechanical parts, which means changing of geometry and
conditions of power transmission, which results in vibrations and shocks, the
measurements for determining the gear failures occur.
