PREDICTIVE STUDY OF MACHINE-TOOLS GEARS
This paper is designed to offer a better understanding of the need for
predictive maintenance for safe operation of machine-tools and minimizing idle
time and reducing repair costs. The ultimate goal of predictive maintenance is
the implementation of maintenance works „when appropriate” before the
equipment is damaged during the operation.

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.

EXPERIMENTAL DETERMINATION OF PROFESSIONAL
NOISE, WITH WORKERS HEALTH IMPLICATIONS
This paper presents measurement results of noise level emitted by a
lathe and effects of noise on health worker. It was noted that in some
circumstances the maximum allowable is exceeded which requires the use of
means of protection.

This paper is a survey of the literature on gear vibration and is
designed to offer a better understanding of the need for predictive maintenance
for safe operation of machine-tools and minimizing idle time and reducing repair
costs. The ultimate goal of predictive maintenance is the implementation of
maintenance works „when appropriate” before the equipment is damaged
during the operation. Main failure in a gear couple of a simple gearbox, are
defects on all teeth and defects localized only on a group of teeth. These
defects can be partitioned defects or localized defects.
