Table "Tbl-1" lists a summary of the possible hazards, their causes and protective
measures for areas with explosion hazards.
Dangers
Possible causes
Protective measures
Hot surfaces
Increased friction and dissipated
power because of wear, improper
assembly, overload, or leaks.
Reduction of the torques and
speeds in comparison to standard
gears
Limiting the motor current and
maximum speed of the motor
Maintenance intervals for wear
parts and lubrication according to
maintenance schedule
Inspection of the temperature
behavior and the running-in
behavior before startup
Regular visual and acoustic
inspections
Prohibition of certain mounting
positions and conditions
Increased surface temperature
because of dust deposits.
Cleaning regulations according to
maintenance plan
Mechanically
caused sparks
Overload on shafts, moving parts
and connection elements.
Reduction of the torques and
external loads in comparison to
standard gears
Limiting the motor current of the
motor
Maximum load test before startup
Electrostatic
loading
Potential differences between
components, cleaning processes,
insulating layers
Grounding the gearhead and the
motor
