How to diagnose gearbox defects early on?
The solutions for analysis and diagnoses of wear and tear are as varied as the possible defects themselves. Damage on bearings is among the most common defects, it becomes noticeable through symptoms like increased noise, elevated bearing temperature or vibrations in the gearbox early on. Detecting bearing damage early on prevents unplanned machine and production shutdowns and any subsequent damages.
An easy and efficient method to detect wear on bearings early on is the analysis of lubricants and monitoring of oil levels. Too high or too low amounts of oil leads to increased bearing temperatures and subsequent damage. Oil analyses will also reveal metallic shavings in the oil, which could be an indicator for increased wear due to overloading.
Thermographic measurements are also a suitable method to detect unusual temperature developments in the bearing and identify causes of damage at an early stage. Thermography is also an easy method which can be conducted without disassembling the gearbox, providing you with important findings about the cause of possible damages in a fast and cost-efficient way.
Wear of gear wheels, seals or tubings are also easily discovered by performing an endoscopy of the gearbox. Here, too, disassembly of the gearbox is not necessary and any damage can be detected quickly and easily.
