Looking for a Best Gear Maintenance ?

You stumbled to the right place!

Bajaj Engineering has developed a gearbox maintenance program consisting of a diagnostics phase, inspection phase (in-shop or on-site) and a repair service. Our proven maintenance program is set-up to minimise downtime and is supported by our in-house diagnostic and machining department and our in-house component manufacturing.

Gearbox Maintenance - Lubrication & Vibration Analysis

Besides gearbox repair, equally important is discovering the root cause of the gearbox failure in order to avoid unplanned machine downtime in the future. To pinpoint equipment failure we perform oil analysis, vibration measurements and thorough visual inspection, for instance examination of abrasive wear patterns and gear tooth pitting.

Root Cause Failure Analysis :

To determine failure root cause we perform both oil analysis and vibration analysis combined with visual inspections. These diagnostic techniques are usually required to monitor the condition of plant machinery and to control the causes of machine failure.

Gearbox Lubrication - Oil Analysis :

In many cases, gear and bearing problems result from contaminated or insufficient oil. Oil filter contamination could cause bearing failure and gear tooth damage. Sometimes insufficient lubrication causes metal-to-metal contact with abrasive wear as a result.

Oil analysis provides important information on wear modes and possible gearbox lubrication problems. On the other hand, visual inspections of wear patterns and gear tooth pitting can reveal lubrication problems e.g. oil leakage or improper lubricants.

Vibration Analysis :

Vibration analysis is an effective technique for monitoring the condition of the gears and bearings and determining the root cause of machine failure. We are able to carry out on-site vibration measurements detecting various sorts of gearbox problems :

  • Gear Damage ( e.g. scoring, abrasive wear )
  • Bearing Defects ( Cage fractures, inner/outer ring damage )
  • Alignment Errors
  • Looseness
  • Imbalance
  • Resonance Areas
