Detects developing faults on gears such as pitting, spalling, and gear cracks using time synchronous averaging to isolate the vibration produced by each gear in a gearbox, while rejecting noise and vibrations from other mechanical components. When a fault such as a pit or crack develops on a tooth, there will be an excessive vibration as the damaged region on the tooth goes through the mesh. This vibration pulse has both low and high frequency content. In most cases, the time synchronous average of the HFE signal will detect the fault earlier and more reliably than standard time synchronous averaging. This analysis can be applied to all the gears in the gearbox using only a single tachometer on the input side of the gearbox. MTC has patented the use of HFE time synchronous averaging for monitoring gears.

Increase Efficiency

• Detect gear mis-assembly following maintenance activities.
• Increase uptime with real-time predictive failure analysis of gears.
• Reduce rapid gear failure caused by misalignments and eccentric running conditions.

Reduce Costs

• Reduce catastrophic failures and unplanned downtime.
• Reduce safety risks related to using hand-held monitoring equipment.
• Maximize effectiveness of downtime by understanding condition of all components in a gearbox.
• Correct root causes of problems rather than running to failure and purchasing expensive components.
