The inspection items in the operation include the rollover, oscillation, temperature, and smooth condition of the IKO bearing; the details are as follows:
1. The roll sound of IKO bearing is selected by the sounder to check the size and sound quality of the IKO bearing in the operation; IKO bearing even if there is slight peeling and other damage; it will announce abnormal sound and irregular sound; The device can be distinguished.
Second, IKO bearing oscillation IKO bearing oscillation is very sensitive to bearing damage; for example, shedding, indentation, rust, crack, wear, etc. will be reflected in the IKO bearing oscillation measurement; therefore; after the selection of special IKO bearing oscillation measuring device ( Frequency analyzer, etc.) can measure the large oscillation.

Third, IKO bearing temperature IKO bearing temperature; usually the temperature outside the bearing can be estimated; if the oil hole can directly measure the IKO bearing outer ring temperature; then more suitable. Usually; IKO bearing temperature follows the operation The beginning gradually rises; after 1-2 hours, the steady temperature is reached. The normal temperature of the IKO bearing is different due to the heat capacity of the machine; the heat dissipation; the speed and load are different. If it is smooth and the device is suitable, the IKO bearing temperature will rise sharply; Abnormal high temperature; at this time it is necessary to suspend operations; adopt the necessary precautions. Use the thermal sensor to monitor the operating temperature of the IKO bearing at any time; and when the temperature exceeds the rule value, actively alarm or stop the ignition of the shaft.
4. Smooth. The smooth smooth effect of IKO bearing has an important influence on the fatigue life of the rolling bearing and the conflict, wear, temperature rise, oscillation, etc.; there is no normal smoothness; the bearing can not work. Professor analyzes the cause of IKO bearing damage Marked; about 40% of IKO bearing damage is related to poor smoothness. Therefore; IKO bearing's outstanding smoothness is a useful way to reduce bearing conflict and wear. In addition, IKO bearing smooth and heat dissipation; rust and seal Various effects such as flat cushioning; the smoothing effect of IKO bearings can be briefly explained as follows:
a. An oil film is formed between the two tumbling surfaces or the sliding outer surface that touch each other to separate the two outer surfaces; the collision and wear of the touch surface are reduced.
b. When the oil is smooth, especially when the circulating oil is smooth, the oil mist is smooth and the fuel injection is smooth; the smooth oil can take away most of the conflict heat inside the IKO bearing; it has a useful heat dissipation effect.
c. When the grease is smooth, it can avoid foreign matter such as dust from entering the IKO bearing;
d. Smoothing agents have the effect of avoiding metal corrosion.
e. Extend the fatigue life of IKO bearings.
The smooth method of the Vedic leg 蠡 冉 IKO bearing is roughly divided into two types: grease smoothness and oil smoothness. In order to give full play to the function of IKO bearing; the important thing is to use the reduction and application intention; select the smooth method. Table 4 -2 shows the advantages and disadvantages of smooth grease and smooth oil.
ㄈ┲蠡 Smooth grease is a smoothing agent composed of base oil; thickener and additives. When selecting; should choose the grease that is very suitable for the bearing application conditions; because the trademark is not the same; there will be very functional Large difference is not the same; so in the time of selection; it is necessary to pay attention to. Smooth grease commonly used in IKO bearings has calcium-based smooth fat, sodium-based smooth fat, calcium-sodium smooth grease, lithium-based smooth fat, aluminum-based smooth fat and disulfide Molybdenum smooth grease, etc. The number of smooth grease filled in IKO bearing; suitable for 1/2-1/3 of the inner space of the overflow bearing. It should be reduced to 1/3 at high speed. Excessive smooth grease makes the temperature rise.
It’s hard to find
When selecting smooth grease according to the operating temperature; the primary target should be the dropping point; oxidation stability and low temperature function; the dropping point can usually be used to evaluate the high temperature function; the IKO bearing practice temperature should be lower than the dropping point 10-20 ° C. The application temperature should be lower than the dropping point of 20-30 ° C. When selecting smooth grease according to IKO bearing load; for heavy load, choose smooth grease with small penetration. When working under high pressure, the penetration is small; High oil film strength and extreme pressure function. When selecting smooth grease according to environmental conditions; calcium-based smooth fat is not easily soluble in water; suitable for boring and less watery environment.
The leg squats under high speed and high temperature conditions; when the grease is smooth, it can be used with smooth oil. After smooth oil circulation; can take away a lot of heat.
Viscosity is an important characteristic of smooth oil; the viscosity of the powder directly affects the fluidity of the smooth oil and the thickness of the oil film formed by the conflicting surface; the viscosity of the smooth oil at the IKO bearing operating temperature is usually 12-15 cst. The higher the rotational speed, the lower the viscosity; The heavier the load, the higher the viscosity should be. The commonly used smooth oils are mechanical oil, high speed mechanical oil, turbine oil, compacting oil, transformer oil, cylinder oil, etc.
The oil smoothing method includes:
a. Oil bath smooth oil bath smooth is the most common smooth method; suitable for the smoothness of low and medium speed bearings; part of the IKO bearing is immersed in the groove; smooth oil is taken up by the rotating bearing parts; then it flows back to the oil groove Slightly below the middle of the lowest roll.
b. Drip oil smooth drip smooth is suitable for demanding quantitative supply of smooth oil IKO bearing parts; the amount of oil is usually one drop every 3-8 seconds; too much oil will lead to IKO bearing temperature increase.
c. The circulating oil is smooth and the oil is pumped to the IKO bearing parts; the smooth oil after the bearing is filtered and cooled, and then used. Because the circulating oil can take away certain heat; the IKO bearing is cooled; therefore, the method is suitable for high speed. IKO bearing components.
d. The spray is smooth and boring with compressed air and sprayed with smooth oil to form an oil mist; in the eruption bearing; the air flow can effectively cool the IKO bearing and avoid the intrusion of impurities. This method is suitable for the smoothing of high-speed, high-temperature IKO bearing components.
e. The jet light slides the high pressure oil through the nozzle into the IKO bearing; the oil injected into the bearing flows into the oil groove through the other end of the IKO bearing. When the IKO bearing rotates at a high speed; the roll and the cage also rotate around at a suitably high rotational speed. The air constitutes the airflow; it is difficult to send the smooth oil to the IKO bearing in a generally smooth manner; it is necessary to spray the smooth oil into the IKO bearing by means of a high-pressure eruption; the nozzle should be placed in the middle of the inner ring and the cage. between.

. ㄆ撸┤蠡 牟 牟 溆敫 。 a. The smooth grease compensates for the interval because of the mechanical effect; the addition of aging and pollution; the smooth base filled in the IKO bearing equipment will gradually lose its smooth function. Therefore, the smooth rank needs to be continuously compensated and updated. Due to the composition, scale and speed of IKO bearings, etc.; the approximate interval of smooth grease is compensated according to the requirements of the operation time. Others; the professor points out that when the IKO bearing temperature exceeds 70 °C; the IKO bearing temperature rises by 15 °C. It is necessary to use the smooth grease to make up half of the interval. The double-sided closed IKO bearing is now loaded with grease; "HRB" uses the standard smooth grease in these products; the total working temperature scale and other functions are suitable for The regular occasion; and the amount of grease is also related to the size of the IKO bearing; the service life of the grease can usually exceed the IKO bearing life; except for special occasions; no need to make up for smooth grease.
b. Replacement cycle of smooth oil The replacement cycle of smooth oil is different depending on the application conditions and oil quantity; usually; when the working temperature is below 50 °C; when it is used in an excellent environment with less dust; replace once a year; when the oil temperature reaches At 100 ° C; replace it once every 3 months or less.
