1. Oil bath lubrication of bearings is a general lubrication method in imported bearings; suitable for lubrication of low and medium speed bearings. The IKO bearing is partially immersed in the groove; the lubricating oil is brought up by the rotating bearing parts; The oil surface that flows back to the oil sump should be slightly lower than the center of the lowest tumbling body.
2, the oil drop lubrication lubrication of the bearing is suitable for the bearing parts that need to supply the lubricating oil quantitatively; the amount of oil drop is appropriate every 3-8 seconds; too much oil will cause the bearing temperature to increase.
3. The circulating oil lubrication of the bearing uses the oil pump to deliver the filtered oil to the bearing components; the lubricating oil after the IKO bearing is filtered and cooled for use. Since the circulating oil can take away certain heat; the bearing is cooled; therefore, the method is applied to Higher speed bearing components.
4. The spray lubrication of the bearing is monotonously shortened by the sprayer and the lubricating oil is turbid to form the oil mist; in the radial bearing; the air flow can effectively cool the bearing and prevent the intrusion of impurities. This method is suitable for the lubrication of high speed and low temperature bearing parts. .
5. The radiation lubrication of the bearing uses the oil pump to shoot the low pressure oil through the nozzle into the bearing; the oil injected into the bearing flows into the oil groove through the other end of the bearing. When the bearing rotates at a high speed; the rolling body and the cage are also rotated at an equal high speed. The surrounding air constitutes the air flow; it is difficult to send the lubricating oil to the bearing by a single lubrication method; at this time, the lubricating oil must be sprayed into the bearing by low-pressure radiation; the position of the nozzle should be placed between the inner ring and the center of the cage.
Different IKO bearing greases are not the same in the general configuration of the bearings; they must be composed in a general analogy; the running time is short; the bearing temperature is low during long hours of operation; and it is stable; this is one A kind of grease that is more ambitious; so it is especially important for the channeling of grease.
Some so-called eddy-flow greases are otherwise; it is not easy to constitute a generalization; even if the generalization is simply collapsed; then the residual grease that is repeatedly returned to the raceway is mixed for a long time; the torque of the bearing is large; the temperature is high; And unbalanced; noise can also occur; grease is also simply transformed and lost.
When the bearing temperature rises, when the bearing temperature rises; the first discriminant can be mishandled; if it is indeed raised; the following should be done:
(1) Check the water pressure of the cooling water; whether the water flow and the pipeline system can be normal. If the water pressure is low, it can be blocked by the filter; if it cannot be disposed of in time; it can be stopped; when it is admitted that it can work;
(2) The oil pressure of the governor should be checked; if the oil pressure is low, the cooling water hydraulic valve can be closed.
(3) Check whether the bearing can have abnormal sound; the bearing can detect whether the bearing swing can be abnormal.
(4) Take the oil sample to investigate whether the oil color can be changed; and carry out the test to see if it can be changed. If the deterioration is recognized; the new oil should be stopped.
(5) Check whether the oil level oil level is normal; if it is abnormal; check if the oil drain valve can be closed. If it is closed, it should be replenished; if it is leaking oil, it should be stopped.
When we use the IKO bearing; if it is found that the temperature is very high; then quickly stop the equipment operation; then find out the reason; and according to the above-mentioned supply treatment plan; but the reason for the bearing heat is different So the method of processing is not the same; so it is still to be detailed in detail; with the assistance of the technical staff to complete.
