In general, if the proper use of INA bearings can be used to the fatigue life is reached. But there will be an accident prematurely damage, intolerance usage. This early damage and fatigue life, failure or accident is called quality limits. More due to the installation, the use of lubrication on the pay no attention to the intrusion of foreign bodies from the outside, for the axis, the thermal effect of the shell is not sufficient.
INA Bearing damage state, such as: card of the INA bearing ring rib injury, as a reason to consider the lack of lubricant and is not suitable for row oil structure defects, foreign body, bearing mounting error and shaft deflection too large, these reasons overlap. Therefore, only investigated the damage, it is difficult to know the real reason of the injury. However, if the use of machinery, bearings and conditions of use, the bearings around the structure, to understand the situation before and after the accident, combined with state of the bearing damage and several reasons to examine, we can prevent similar incidents from happening again.
First, the bearing of the oscillation
INA Bearing oscillation INA Bearing damage is very keen, for example, peeling, creasing, corrosion, cracks, wear, etc. will be reflected in the investigation of bearing oscillation, so after it thinks fit to use a special bearing oscillation survey (frequency parser ) to survey the volume of the oscillation after frequency can not infer the exception of the specific situation of things. Figures measured bearing the use of conditions or sensor installation location is not the same, because the purposes of analysis of this requirement prior to the survey value of each machine, confirm that criteria.
Second, the bearing temperature
INA Bearing temperature, the temperature of the bearings outside the room can measure, if the hole can direct investigation of the temperature of the bearing outer ring more bit appropriate.
In general the INA bearing temperature with the operation of the INA Bearing proceed slowly rose up, 1-2 hours to reach the prison stable condition. The normal temperature of the bearing due to the amount of thermal capacity of the machine, the bulk of calories, speed and load without. If appropriate lubricant, install the Ministry, the bearing temperature will rapidly rise up revealed abnormal high temperature, then be sure to repose operation, take the indispensable preparedness approach.
The use of thermal sensors to the office temperature at any time to monitor detection of INA bearings, and a successful semi-automatic alarm when the temperature exceeds the specified value or repose avoid burning shaft accident.
High temperature, often expressed in a situation of abnormal things. The high temperatures in the obstruction of the INA Bearing lubricant agent. Sometimes bearing overheating can be attributed to the bearing lubricant agent. INA Bearing in more than 125 ℃ temperature a long time even move to reduce the survival of bearing age. -Induced high temperature bearing CMU include: lubricating oil is not sufficient or not for himself and even lubricants, lubricating agent. Includes impurities, the load is too large, bearing loss of the ring, the gap is not sufficient, and the oil seal initiation bearing friction.
This reelection surveillance detection INA bearing temperature is indispensable, regardless of the measurement bearing or other tightly closed parts. Conditions of operating conditions has not changed things, no matter what the temperature change can be expressed has failed.
INA Bearing temperature regular measurements by means of the thermometer, the cases according to the number of fonts thermometer, a very accurate measure bearing temperature and revealed according to the given unit of ℃ or Fahrenheit. Close INA bearings, which means when their destruction will lead to the shutdown of the facility, because this type of bearing is best should be retrofitted with a temperature probe observer. The normal condition of things, bearing in just lubricating oil or lubricating oil after there will be a natural temperature rose up Moreover, a continuous one to two days.
