IKO bearings in the use of check the maintenance operation key points

Bearing in the operation of inspection is very important, can not be ignored, check the main bearings of rolling noise, vibration, temperature, lubrication condition and so on. We will start with simple introduce IKO bearings rolling, the size of the rumbling and quality check sound device should be used for inspection of auto bearing in operation, with advanced tools can accurately judge the problem, bearing even with slight stripping damage, such as would an exception and irregular, and with the sound of the measuring device can distinguish. Then bearing vibration test to check the bearing damage is very sensitive, peeling, indentation, rust, crack and wear will be reflected in the bearing vibration measurement, therefore, through the use of special auto bearing vibration measuring device ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. However, each machine measured values for IKO bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard. 1, when used in bearing, connecting the surroundings clean, do not stick to fit the sweat and dirt. Designated by the understanding of the staff are allowed to use bearing, especially necessary small sad, indentation, owe loss, etc. For guaranteeing the use of the bearing function, should be in accordance with the equipment work scale, timely to protect bearings, aftercare and inspection, include monitoring operation condition, make up for the smooth agent, assembling a raid on schedule. 2, bearing may not directly on the ground storage ( To more than 30 cm) from the ground To prevent direct light and cold wall. In order to guard against rust, custody is about 20 ℃ temperature, environment humidity below 65%, auto bearing arrangement in acidic atmosphere, easy to rust, discoloration, to use gloves, kapok, waste wipes bearing, axis, a hood, dregs into IKO bearing external and common department is to produce the cause of abnormal, is necessary to carefully. 3, bearing measurement deviation, 10% of the public servants should be as follows. General military difference measurement deviation of 10% ~ 33%, and follow the progress of the grade of public service, the proportion of deviation, the greater the i. e. public servants is smaller, the higher the proportion of deviation, and auto bearing, the public service more than IT5 it's difficult to reach 10%. Measurement deviation means not only can relax 10% inspection and service, but to give must be safe margin, to guaranteeing user acceptance according to the scale to pass the exam. 4, bearing in the past also raided the exiguity and gage block, scales and measurement instruments used in the raid with arrangement in a raid in a piece of metal plate, such as licensing quickly make these objects of homogenization temperature and room temperature. Has to dry or drying IKO bearings, shall delimit the oil drip into the smooth and immediate entrust a raid, the outside situation without the oil film bearing, in the process of all raid shall direct the war and the skin of hands, the operator should wear clean gloves, or hand coated with rust inhibitor, but must prevent the rotation of the hands of anti-rust agent mixed with auto bearing, or you will make the measurement results. Bearing temperature generally have a bearing on the surface of the outdoor temperature can be deduced, for this is simple, if using the oil hole can directly measure temperature of bearing outer ring, is more appropriate. Usually, the temperature of the bearing with operation began to slowly rise, 1 - After 2 hours to reach steady state. IKO bearing normal temperature due to the heat capacity of the machine, heat dissipating capacity, rotational speed and load. If the appropriate lubrication, installation department, the bearing temperature will rise sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions. Based on a lot of test data, because the temperature by lubrication, rotational speed, load, the influence of the environment, so you should use thermal device can monitor cars bearing operating temperature, and implement e. automatic alarm when the temperature is more than the household or stop to prevent the shaft accidents.
