Maintenance of Gearboxes and Electric motors

  • Check gear boxes and gear motors periodically for cleanliness. Avoid accumulation of dust on the gear box, motor and motor cowl etc.
  • Check the mounting bolts and electrical connections periodically (once in a month) for correct torque.
  • Apply anti-sieze compound once in twelve months on the motor coupling shaft.
  • Avoid accumulation of dust on the oil seals. This can erode oil seals and cause oil leakage.
  • Check for oil level daily. If required, top it up with correct grade oil as per the table.
    Check the current drawn by the motor periodically as specified in the name plate.
  • Keep the motor clean from dust and oil.
  • Check the seal rings on the electric motor for good condition.
  • Electric motor bearings are lubricated for life. If any abnormal noise is observed, bearing shall be replaced

Dos and Donts

  • Check for oil level daily
  • Fill oil ISOVG320 in gear boxes from size VF110 to VF18
  • Check the condition of the oil seals
  • When fitting the belt driven pulleys, make sure that the shafts are perfectly parallel and that the pulleys are aligned with each other
  • Provide overload protection to the electric motors
  • Protect motor from water and humidity
  • Do not block the breather holes if its is provided. This may lead to the internal pressure and consequent leakage of oil from oil seals and rubber caps.
  • Do not paint on the oil seals Do not hammer the output / input shafts while fitting the pulley or any other drive mechanism. This may lead to breakage of internals
  • Incorrect alignment can cause damage to the motor and the input shaft bearings
  • Avoid over-tensioning the belts since excess tension can cause bearing failure in the gear box
  • Do not run the motor in high voltage fluctuation
  • Do not disturb the original brake settings
  • Do not give brake supply connections separately as it is already connected internally
