INA bearings at work allows slight noise, if the noise is too large or unusual noise or crash, it indicates that the oil-bearing has failed.
Rolling noise is more complex reasons, one is the bearing inner and outer rings with surface wear. Because of this wear and tear, damage to the bearing and the housing, the bearing and shaft with the relationship, leading to a deviation from the correct position axis, the axis moves at high speed generate abnormal sound. When the bearing fatigue, the surface metal flake, but also make the bearing radial clearance increased abnormal sound. In addition, INA Bearing insufficient lubrication, the formation of dry friction, and bearing broken, etc. will have an unusual sound. After the oil-bearing wear Songkuang the cage loose damage, will produce abnormal noise.
At the institutional operation, install the bearing parts allow a certain temperature, when the stroking mechanism housing should not feel hot to normal, otherwise indicates that the bearing temperature.
Oil quality does not meet the requirements or deterioration, lubricant viscosity is too high; institutions assembly too tight (lack of space); INA bearing assembly tight; oil-bearing ring on the shaft or housing rotation; overload; bearing retainer or rolling fragmentation.
From peeling, indentation, corrosion, cracks, wear, etc. will be in INA Bearing vibration measurement reflected view, bearing vibration of the bearing damage is very sensitive, so, through the use of special oil-bearing vibration measurements (frequency analysis etc.) to measure the size of the vibration, frequency points can not be inferred abnormal circumstances. Since the measured values due to the conditions of use of the bearing or sensor installation location is different, so each machine needs prior to analysis and comparison of the measured values determined criteria.
Because INA Bearing peeling even a slight injury, will be an abnormal tone and irregular sound, hence the sound measuring device can be resolved using sound measuring device, for operation of the oil-bearing rolling sound quality for the size and inspection, played the role of prevention in advance.
If the hole can be measured directly using the bearing outer ring temperature is more suitable position. Generally, INA bearing temperature, generally based on the temperature outside the bearing chamber can be inferred. If lubrication, install the appropriate department, the abrupt bearing temperature will rise, there will be an abnormally high temperature, time to stop running, take the necessary precautions. Typically, the bearing temperature rise slowly as the operation starts 1-2 hours after reaching steady state. The normal temperature because of the machine bearing the heat capacity, heat capacity, speed and load are different. If necessary, you can always use the thermal sensor to monitor oil-bearing operating temperature, and to achieve the temperature exceeds a predetermined value or when the alarm automatically stops to prevent burning shaft household accidents.
