KOYO import bearings of daily maintenance and maintenance method - bearing latest knowledge

A, KOYO import bearing maintenance technical problems are as follows: the KOYO import bearing maintenance technology of two complex the problem is: 1, when an oil change. 2, how much oil should be changed. If an oil change is too little, the bearing will be scrapped in advance; If there is excessive oil change, KOYO import bearings would get into trouble or long-term harm power coil and roll line. Second, KOYO import bearing maintenance technology: decide when to lubrication and when to stop filling the way is very simple: make a base line, making observation schedule and to monitor the oil. 1, establish a base line KOYO import bearing base line reflected in normal operation, no apparent mistake, enough db strength under the condition of lubrication. Develop basic line three ways: 1) , comparative law: if there is more than the same type of KOYO import bearings, the bearing can be put together to compare. In the same test method or from the same Angle to observe each bearing. Analysis of db strength and sound quality. There is no essential difference (if Less than 8 decibels) We can set it as the basis for each bearing KOYO import db strength. 2) Add lubricating oil, set the base line, when add lubricating oil, listen to sounds, when the intensity of the sound down then up. At this time, don't add too much oil, and set it on the basis of the line. 3) , history: to observe the KOYO import bearing strength of decibels, record every day, and then compare the record of 30 days. If the db intensity change very little or no change ( Less than 8 decibels) , we can set the line, and the comparative value for future observations. 2, set up the observation schedule such as related to production, environment, operation results of equipment key is to choose and set up the main factors of evaluation of mechanical system. After the basic observation line set, is necessary to test once a month. For those who want to high decibel KOYO import bearing lubrication, should be testing the frequency of more frequent, so that you can observe it the possibility of change. If a KOYO import bearings is in a state will be destroyed, the lubricating oil can only temporarily cover a mistake. However, db strength will soon rise to display errors exist. In some cases, this kind of phenomenon will emerge in a few minutes, some needs a few days. 3,, lubrication tests if a KOYO import bearing db based line more than 8 db, we think that the bearing lubrication. When we realized that the bearing lubrication is needed, know when to stop to prevent excessive lubricating oil will appear. Can be finished according to the following three steps: 1) , imported by KOYO bearing manufacturers based on the guidance of dosage calculation, and then into the lubricating oil, not too much. This step is very subjective, and have nothing to do with ultrasonic, and this step never fail. 2) , when injecting grease lubrication technicians used ultrasonic instrument testing bearing. Oil slowly until the db intensity to a base line. 3) As a guide, if there is no base line, the amount of lubricating oil shall cease after the voice down and up. At this moment, the technician should stop continue to use the lubricating oil. 4, ultrasonic KOYO import bearing inspection ultrasonic inspection or monitoring is realized KOYO import bearing damage early ( At the beginning) The most reliable method. When the temperature or low frequency vibration intensity strengthened, ultrasonic warning will be the first ring. Early when bearing damage due to excessive use, the lack of a glut of oil or oil, use this method of inspection KOYO import bearings is very useful. 5, find failure signal like metal on the tracks of globular KOYO import bearings, such as roller or ball bearings began to overuse, small deformation occurs. This kind of situation will produce irregular surface, resulting in increase of ultrasonic. From the initial reading of the amplitude of the change shows that one of two conditions: the failure or lack of lubricating oil and the early bearing failure in advance. If the ultrasonic based line more than eight decibels, will keep on the impact of the noise, accompanied by the noise that lubricating oil failure ( Dry bearing surface) 。 If the ultrasonic reading more than expected readings, at 12 decibels, there will be a collapse of the noise, the noise can be assumed to KOYO import bearings has begun to enter the failure mode.
