1.TIMKEN bearings during use due to the reasons of quality and external conditions, and its carrying capacity, rotation accuracy and wear resistance will change when spherical bearings performance indicators below the use requirement was not working properly, bearing failure or even failure, Rolling in the event such as the failure of unforeseen circumstances, machinery, equipment will stall the loss of function and other anomalies, found to occur in the short term, and take the appropriate measures.
2 bearing vibration
Bearing vibration TIMKEN bearing failure effect is obvious. Example: peeling, creasing, rust, cracks, wear and will be reflected in the detection of bearing vibration, and so through the use of special rolling bearing vibration measuring devices (frequency analyzers and vibration analyzer , etc.) measure the size of the vibration frequency distribution inferred the specific circumstances of the abnormal vibration, the measured values due to the conditions of use of the bearing or sensor installation location is different and therefore require prior analyze the measured value of each machine compared to determine the criteria.
(3) bearing temperature
Usually bearing temperature as the operation began to slowly rise after 1-2 hours to reach steady state. Bearings TIMKEN the normal temperature of the heat capacity of the machine, heat dissipation, speed and load vary. Lubrication, installation is inappropriate, then the bearing The temperature will rise abrupt, abnormal high temperature, then must stop and take the necessary precautions.
TIMKEN bearing metallurgical quality of the materials once the impact Rolling early failure of the main factors. Metallurgical technology (such as advances in bearing steel vacuum degassing, etc.), raw material quality is improved. The proportion of raw material quality factors in the analysis of bearing failure has decreased significantly, but it is still one of the main factors affecting rolling bearing failure. The selection of the adequacy of the still bearing failure analysis must take into consideration.
