Spherical roller bearing inspection method
Clicks:14250 Date:11-14
Spherical roller bearing produced a certain amount of wear, will be reflected in all aspects, there are several common phenomena.
1. produce ink bar
In the pages of newspapers, a color ink appears a color light or no such ink. In the case of severe wear, the whole picture may appear blurred or not ink. When this fault occurs, you can suspect spherical roller bearing there are problems, but first also need to exclude cots factors.
2. grinding plate
In the newspaper printing process, when the PS edition plates and compared to the previous version is more and more low, grinding phenomenon is serious, and even cracked version of the phenomenon, can also be suspected spherical roller bearing if there is a problem. In this case, first of all need to queue rubber roller pressure is too large factor.
3. machine vibration increase
When the spherical roller bearing in the normal state, the machine will vibrate the sound soft and uniform; when spherical roller bearing wear machine, vibration and sound will increase. Especially during the roller wear, if used a metal rod to a head on the operation side of the shaft neck, a head in the ear, they heard a violent crash obviously.
4. printing cylinder gap change
If spherical roller bearing wear, through the gap between the standard feeler roller, it can be found the printing pressure changes. Especially, when the gap value and standard value are above 0.05mm, the work condition of spherical roller bearing should be focused on. Of course, not all printing drum gap changes are caused by spherical roller bearing wear, and sometimes it may be offset due to eccentricity. Pay special attention to this point.
The circle runout of the 5. roller surface is larger
When spherical roller bearing wear serious, roller surface runout usually above 0.04mm, so it can be measured on the surface of the roller with magnetic table and dial gauge, to determine whether there is the problem.
6. using bearing fault detector for analysis
Now many manufacturers of detection equipment development and production of the bearing fault detector, method of this kind of instrument commonly used shock pulse technology or application status and detection of oil film lubrication state monitoring of spherical roller bearing. Conditional manufacturers can use this method for testing.
In addition, the problem can be found by measuring the temperature of the outer surface of the metal at the spherical roller bearing installation. Under special circumstances, the problem can be found according to the different structural characteristics of the machine. Such as when the GEOMAN newspaper web offset press axial alignment system can not be successfully pulled adjustment, it is possible to indicate the bearing plate cylinder wear, because the plate cylinder surface mechanical transmission structure determines when the plate spherical roller bearing wear will affect a larger adjustment of axial tension register system.
In a word, when judging whether the spherical roller bearing is worn seriously, it should be used synthetically to judge the above situations.
